- The 3 patch series "hung_task: extend blocking task stacktrace dump to
semaphore" from Lance Yang enhances the hung task detector. The
detector presently dumps the blocking tasks's stack when it is blocked
on a mutex. Lance's series extends this to semaphores.
- The 2 patch series "nilfs2: improve sanity checks in dirty state
propagation" from Wentao Liang addresses a couple of minor flaws in
nilfs2.
- The 2 patch series "scripts/gdb: Fixes related to lx_per_cpu()" from
Illia Ostapyshyn fixes a couple of issues in the gdb scripts.
- The 9 patch series "Support kdump with LUKS encryption by reusing LUKS
volume keys" from Coiby Xu addresses a usability problem with kdump.
When the dump device is LUKS-encrypted, the kdump kernel may not have
the keys to the encrypted filesystem. A full writeup of this is in the
series [0/N] cover letter.
- The 2 patch series "sysfs: add counters for lockups and stalls" from
Max Kellermann adds /sys/kernel/hardlockup_count and
/sys/kernel/hardlockup_count and /sys/kernel/rcu_stall_count.
- The 3 patch series "fork: Page operation cleanups in the fork code"
from Pasha Tatashin implements a number of code cleanups in fork.c.
- The 3 patch series "scripts/gdb/symbols: determine KASLR offset on
s390 during early boot" from Ilya Leoshkevich fixes some s390 issues in
the gdb scripts.

- The 11 patch series "Add folio_mk_pte()" from Matthew Wilcox
simplifies the act of creating a pte which addresses the first page in a folio and reduces the amount of plumbing which architecture must implement to provide this. - The 8 patch series "Misc folio patches for 6.16" from Matthew Wilcox is a shower of largely unrelated folio infrastructure changes which clean things up and better prepare us for future work. - The 3 patch series "memory,x86,acpi: hotplug memory alignment advisement" from Gregory Price adds early-init code to prevent x86 from leaving physical memory unused when physical address regions are not aligned to memory block size. - The 2 patch series "mm/compaction: allow more aggressive proactive compaction" from Michal Clapinski provides some tuning of the (sadly, hard-coded (more sadly, not auto-tuned)) thresholds for our invokation of proactive compaction. In a simple test case, the reduction of a guest VM's memory consumption was dramatic. - The 8 patch series "Minor cleanups and improvements to swap freeing code" from Kemeng Shi provides some code cleaups and a small efficiency improvement to this part of our swap handling code. - The 6 patch series "ptrace: introduce PTRACE_SET_SYSCALL_INFO API" from Dmitry Levin adds the ability for a ptracer to modify syscalls arguments. At this time we can alter only "system call information that are used by strace system call tampering, namely, syscall number, syscall arguments, and syscall return value. This series should have been incorporated into mm.git's "non-MM" branch, but I goofed. - The 3 patch series "fs/proc: extend the PAGEMAP_SCAN ioctl to report guard regions" from Andrei Vagin extends the info returned by the PAGEMAP_SCAN ioctl against /proc/pid/pagemap. This permits CRIU to more efficiently get at the info about guard regions. - The 2 patch series "Fix parameter passed to page_mapcount_is_type()" from Gavin Shan implements that fix. No runtime effect is expected because validate_page_before_insert() happens to fix up this error. - The 3 patch series "kernel/events/uprobes: uprobe_write_opcode() rewrite" from David Hildenbrand basically brings uprobe text poking into the current decade. Remove a bunch of hand-rolled implementation in favor of using more current facilities. - The 3 patch series "mm/ptdump: Drop assumption that pxd_val() is u64" from Anshuman Khandual provides enhancements and generalizations to the pte dumping code. This might be needed when 128-bit Page Table Descriptors are enabled for ARM. - The 12 patch series "Always call constructor for kernel page tables" from Kevin Brodsky "ensures that the ctor/dtor is always called for kernel pgtables, as it already is for user pgtables". This permits the addition of more functionality such as "insert hooks to protect page tables". This change does result in various architectures performing unnecesary work, but this is fixed up where it is anticipated to occur. - The 9 patch series "Rust support for mm_struct, vm_area_struct, and mmap" from Alice Ryhl adds plumbing to permit Rust access to core MM structures. - The 3 patch series "fix incorrectly disallowed anonymous VMA merges" from Lorenzo Stoakes takes advantage of some VMA merging opportunities which we've been missing for 15 years. - The 4 patch series "mm/madvise: batch tlb flushes for MADV_DONTNEED and MADV_FREE" from SeongJae Park optimizes process_madvise()'s TLB flushing. Instead of flushing each address range in the provided iovec, we batch the flushing across all the iovec entries. The syscall's cost was approximately halved with a microbenchmark which was designed to load this particular operation. - The 6 patch series "Track node vacancy to reduce worst case allocation counts" from Sidhartha Kumar makes the maple tree smarter about its node preallocation. stress-ng mmap performance increased by single-digit percentages and the amount of unnecessarily preallocated memory was dramaticelly reduced. - The 3 patch series "mm/gup: Minor fix, cleanup and improvements" from Baoquan He removes a few unnecessary things which Baoquan noted when reading the code. - The 3 patch series ""Enhance sysfs handling for memory hotplug in weighted interleave" from Rakie Kim "enhances the weighted interleave policy in the memory management subsystem by improving sysfs handling, fixing memory leaks, and introducing dynamic sysfs updates for memory hotplug support". Fixes things on error paths which we are unlikely to hit. - The 7 patch series "mm/damon: auto-tune DAMOS for NUMA setups including tiered memory" from SeongJae Park introduces new DAMOS quota goal metrics which eliminate the manual tuning which is required when utilizing DAMON for memory tiering. - The 5 patch series "mm/vmalloc.c: code cleanup and improvements" from Baoquan He provides cleanups and small efficiency improvements which Baoquan found via code inspection. - The 2 patch series "vmscan: enforce mems_effective during demotion" from Gregory Price "changes reclaim to respect cpuset.mems_effective during demotion when possible". because "presently, reclaim explicitly ignores cpuset.mems_effective when demoting, which may cause the cpuset settings to violated." "This is useful for isolating workloads on a multi-tenant system from certain classes of memory more consistently." - The 2 patch series ""Clean up split_huge_pmd_locked() and remove unnecessary folio pointers" from Gavin Guo provides minor cleanups and efficiency gains in in the huge page splitting and migrating code. - The 3 patch series "Use kmem_cache for memcg alloc" from Huan Yang creates a slab cache for `struct mem_cgroup', yielding improved memory utilization. - The 4 patch series "add max arg to swappiness in memory.reclaim and lru_gen" from Zhongkun He adds a new "max" argument to the "swappiness=" argument for memory.reclaim MGLRU's lru_gen. This directs proactive reclaim to reclaim from only anon folios rather than file-backed folios. - The 17 patch series "kexec: introduce Kexec HandOver (KHO)" from Mike Rapoport is the first step on the path to permitting the kernel to maintain existing VMs while replacing the host kernel via file-based kexec. At this time only memblock's reserve_mem is preserved. - The 7 patch series "mm: Introduce for_each_valid_pfn()" from David Woodhouse provides and uses a smarter way of looping over a pfn range. By skipping ranges of invalid pfns. - The 2 patch series "sched/numa: Skip VMA scanning on memory pinned to one NUMA node via cpuset.mems" from Libo Chen removes a lot of pointless VMA scanning when a task is pinned a single NUMA mode. Dramatic performance benefits were seen in some real world cases. - The 2 patch series "JFS: Implement migrate_folio for jfs_metapage_aops" from Shivank Garg addresses a warning which occurs during memory compaction when using JFS. - The 4 patch series "move all VMA allocation, freeing and duplication logic to mm" from Lorenzo Stoakes moves some VMA code from kernel/fork.c into the more appropriate mm/vma.c. - The 6 patch series "mm, swap: clean up swap cache mapping helper" from Kairui Song provides code consolidation and cleanups related to the folio_index() function. - The 2 patch series "mm/gup: Cleanup memfd_pin_folios()" from Vishal Moola does that. - The 8 patch series "memcg: Fix test_memcg_min/low test failures" from Waiman Long addresses some bogus failures which are being reported by the test_memcontrol selftest. - The 3 patch series "eliminate mmap() retry merge, add .mmap_prepare hook" from Lorenzo Stoakes commences the deprecation of file_operations.mmap() in favor of the new file_operations.mmap_prepare(). The latter is more restrictive and prevents drivers from messing with things in ways which, amongst other problems, may defeat VMA merging. - The 4 patch series "memcg: decouple memcg and objcg stocks"" from Shakeel Butt decouples the per-cpu memcg charge cache from the objcg's one. This is a step along the way to making memcg and objcg charging NMI-safe, which is a BPF requirement. - The 6 patch series "mm/damon: minor fixups and improvements for code, tests, and documents" from SeongJae Park is "yet another batch of miscellaneous DAMON changes. Fix and improve minor problems in code, tests and documents." - The 7 patch series "memcg: make memcg stats irq safe" from Shakeel Butt converts memcg stats to be irq safe. Another step along the way to making memcg charging and stats updates NMI-safe, a BPF requirement. - The 4 patch series "Let unmap_hugepage_range() and several related functions take folio instead of page" from Fan Ni provides folio conversions in the hugetlb code. -----BEGIN PGP SIGNATURE----- iHUEABYKAB0WIQTTMBEPP41GrTpTJgfdBJ7gKXxAjgUCaDt5qgAKCRDdBJ7gKXxA ju6XAP9nTiSfRz8Cz1n5LJZpFKEGzLpSihCYyR6P3o1L9oe3mwEAlZ5+XAwk2I5x Qqb/UGMEpilyre1PayQqOnct3aSL9Ao= =tYYm -----END PGP SIGNATURE----- Merge tag 'mm-stable-2025-05-31-14-50' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Pull MM updates from Andrew Morton: - "Add folio_mk_pte()" from Matthew Wilcox simplifies the act of creating a pte which addresses the first page in a folio and reduces the amount of plumbing which architecture must implement to provide this. - "Misc folio patches for 6.16" from Matthew Wilcox is a shower of largely unrelated folio infrastructure changes which clean things up and better prepare us for future work. - "memory,x86,acpi: hotplug memory alignment advisement" from Gregory Price adds early-init code to prevent x86 from leaving physical memory unused when physical address regions are not aligned to memory block size. - "mm/compaction: allow more aggressive proactive compaction" from Michal Clapinski provides some tuning of the (sadly, hard-coded (more sadly, not auto-tuned)) thresholds for our invokation of proactive compaction.

require gcc-8 and binutils-2.30
x86 already uses gcc-8 as the minimum version, this changes all other architectures to the same version. gcc-8 is used is Debian 10 and Red Hat Enterprise Linux 8, both of which are still supported, and binutils 2.30 is the oldest corresponding version on those. Ubuntu Pro 18.04 and SUSE Linux Enterprise Server 15 both use gcc-7 as the system compiler but additionally include toolchains that remain supported. With the new minimum toolchain versions, a number of workarounds for older versions can be dropped, in particular on x86_64 and arm64. Importantly, the updated compiler version allows removing two of the five remaining gcc plugins, as support for sancov and structeak features is already included in modern compiler versions. I tried collecting the known changes that are possible based on the new toolchain version, but expect that more cleanups will be possible. Since this touches multiple architectures, I merged the patches through the asm-generic tree. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEo6/YBQwIrVS28WGKmmx57+YAGNkFAmg6vNMACgkQmmx57+YA GNkOmg/+LtR9B2P27GPBeG8HnLTZ8hKELiyYeSk6ZFgQv5hevE37HV35Yru7e7gu wcF6CgYr8ff4CVcHM7y0790oGew1thkqq5CklFIH0EwCDJx/mWfZR1SS2jfZIEWM HSDOlQQd1S8oWia14tSnQos3nW3CB9/ABVTHH+Wvl3xn48WMRvgK2LJgGLuxJrt8 5DD9auHiLjchWB5tB4DU98IgWWgFUGMTsI6IayZ4dkF4CdWqd89h0Y3pjJYeBgHS mPxzR2q8WjEmG9hp7QuZQgn/pAYleJAwHvvkoLrkQ2ieqx3FjWiwFbQp4CG1Sc8L eBR1lnkqS2z/e7xJLfe86fOoKWWu4I0tZKhRan/0+UOGm5nXrGpqSxKS8ZDsRuAp 3fvyhIp1cYSa7Xkok8BFhLEFR0tguXJXnXBc3tWE5VXIfFNd0Ohh1GUYhXDAqWKh i0jN9dSNhokM3AqBi6qZl5kmBnRA3UsIaOg3QRrqN8IlBPp+u7i5xsrJIUWvD95o TO06admmLcCJT8n6ZfNVfRjBgzu8+t54UVaDx9YYwxoNGOSFwqOb8CSPTWPxLmDr RKDUOvO8DBlP7uFz9neP+LxluA3DjurRZvb0z0AmCZ8/RXEmTMCyfP5a6esxquXt 0Bqo6hM9q+TeXTHNS1CNvqLSWWikw+AzS/ZPPvriYFn5lxtbq6c= =pdDC -----END PGP SIGNATURE----- Merge tag 'gcc-minimum-version-6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic Pull compiler version requirement update from Arnd Bergmann: "Require gcc-8 and binutils-2.30 x86 already uses gcc-8 as the minimum version, this changes all other architectures to the same version. gcc-8 is used is Debian 10 and Red Hat Enterprise Linux 8, both of which are still supported, and binutils 2.30 is the oldest corresponding version on those.

soc: devicetree updates for 6.16
There are 11 newly supported SoCs, but these are all either new
variants of existing designs, or straig reuses of the existing
chip in a new package:
- RK3562 is a new chip based on the old Cortex-A53 core, apparently
a low-cost version of the Cortex-A55 based RK3568/RK3566.
- NXP i.MX94 is a minor variation of i.MX93/i.MX95 with a different
set of on-chip peripherals.
- Renesas RZ/V2N (R9A09G056) is a new member of the larger RZ/V2 family
- Amlogic S6/S7/S7D
- Samsung Exynos7870 is an older chip similar to Exynos7885
- WonderMedia wm8950 is a minor variation on the wm8850 chip
- Amlogic s805y is almost idential to s805x
- Allwinner A523 is similar to A527 and T527
- Qualcomm MSM8926 is a variant of MSM8226
- Qualcomm Snapdragon X1P42100 is related to R1E80100
There are also 65 boards, including reference designs for the chips
above, this includes
- 12 new boards based on TI K3 series chips, most of them from
Toradex
- 10 devices using Rockchips RK35xx and PX30 chips
- 2 phones and 2 laptops based on Qualcomm Snapdragon designs
- 10 NXP i.MX8/i.MX9 boards, mostly for embedded/industrial uses
- 3 Samsung Galaxy phones based on Exynos7870
- 5 Allwinner based boards using a variety of ARMv8 chips
- 9 32-bit machines, each based on a different SoC family
Aside from the new hardware, there is the usual set of cleanups and
newly added hardware support on existing machines, for a total of 965
devicetree changesets.

ARM: soc updates for 6.16
The main update in size is the removal of the TI DaVinci DA830 SoC support. DA830 is similar to DA850, which remain supported, but only the reference board was ever supported, and we removed that one 3 years ago as it had never been converted to devicetree. There are some other cleanups for OMAP4 and a few boards using old GPIO interfaces. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEo6/YBQwIrVS28WGKmmx57+YAGNkFAmg532EACgkQmmx57+YA GNk1Wg/+LyNX9SX/OrHa0mIv8MpVd+JqJQccFRQ1M9Yt53xPbG+7iToQkRicMS6+ 1dUPypjt9dSh8dTxwZ4zMEZ/x6Pg8j5CxW74ye0s5ympq/EFCab07DTayZUmj0XL C2NDpCTec47uD8BjAf03wdsw34Qd5I9JIjWXoWo9o4MtUHenaMn86TCuCdWyclMi 8JZLnyW+D+K2u1LAmh43L9JidHYCd90N6gDKpcWL37FrEcJR+8AI8XLNWViyOEq2 ow7aj5KTtcmChslgxMtQcxOJ32g0u3RAUdf24OrptYA0RfYmxzscyWoTpCWYket6 H9xnrz+OHejabVRa484FeHSQRRRgwdNR8eAKNs/NQIf5SM/SWuQy8vQu9wJEA9gm 2iNF6c4vSl65xu/LwamlkIMBEM7XY+ABtkJ63LaLHQaQ2NB7Cc8OebQXRhUNS6Dm tdTdFz5aw+vN1r6zobQ3Lk4DpA0SUueTHOc9GYXdp0piKANWTUL/oYBEVR10gSto vtUOWHUeoeaTffqWTJvOXq9YsXOAk71bBHa+uqrYz2Q12zuohWfB82uPU4jgiWAK SaMCo27HKmTdEctzA0fSEfel26C4SephMmu7QiCtGgwCnR6F1nlztyjjYVzt5DtZ t9iXXIk8K5B7W7WARU8DnSQFHgc49SowbRhrV0EpC4j2grs8Ix0= =8hph -----END PGP SIGNATURE----- Merge tag 'soc-arm-6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull ARM SoC updates from Arnd Bergmann: "The main update in size is the removal of the TI DaVinci DA830 SoC support.

fbdev: Fix fb_set_var to prevent null-ptr-deref in fb_videomode_to_var
If fb_add_videomode() in fb_set_var() fails to allocate memory for
fb_videomode, later it may lead to a null-ptr dereference in
fb_videomode_to_var(), as the fb_info is registered while not having the
mode in modelist that is expected to be there, i.e. the one that is
described in fb_info->var.

The reason is that fb_info->var is being modified in fb_set_var(), and
then fb_videomode_to_var() is called. If it fails to add the mode to
fb_info->modelist, fb_set_var() returns error, but does not restore the
old value of fb_info->var. Restore fb_info->var on failure the same way
it is done earlier in the function.

================================================================
Even though fbcon_init() checks beforehand if fb_match_mode() in
var_to_display() fails, it can not prevent the panic because fbcon_init()
does not return error code. Considering this and the comment in the code
about fb_match_mode() returning NULL - "This should not happen" - it is
better to prevent registering the fb_info if its mode was not set
successfully. Also move fb_add_videomode() closer to the beginning of
do_register_framebuffer() to avoid having to do the cleanup on fail.

fbdev: core: fbcvt: avoid division by 0 in fb_cvt_hperiod()
In fb_find_mode_cvt(), iff mode->refresh somehow happens to be 0x80000000,
cvt.f_refresh will become 0 when multiplying it by 2 due to overflow. It's
then passed to fb_cvt_hperiod(), where it's used as a divider -- division
by 0 will result in kernel oops. Add a sanity check for cvt.f_refresh to
avoid such overflow...

fbcon: Make sure modelist not set on unregistered console
It looks like attempting to write to the "store_modes" sysfs node will
run afoul of unregistered consoles:

If con2fb_map contains a -1 things go wrong here. Instead, return NULL,
as callers of fbcon_info_from_console() are trying to compare against
existing "info" pointers, so error handling should kick in correctly.

==================================================================
By analyzing the vmcore, we found that vc->vc_origin was somehow placed
one line prior to vc->vc_screenbuf when vc was in KD_TEXT mode, and
further writings to /dev/vcs caused out-of-bounds reads (and writes
right after) in vcs_write_buf_noattr().
Our further experiments show that in most cases, vc->vc_origin equals to
vga_vram_base when the console is in KD_TEXT mode, and it's around
vc->vc_screenbuf for the KD_GRAPHICS mode. But via triggerring a
TIOCL_SETVESABLANK ioctl beforehand, we can make vc->vc_origin be around
vc->vc_screenbuf while the console is in KD_TEXT mode, and then by
writing the special 'ESC M' control sequence to the tty certain times
(depends on the value of `vc->state.y - vc->vc_top`), we can eventually
move vc->vc_origin prior to vc->vc_screenbuf. Here's the PoC, tested on
QEMU:
```
int main() {
const int RI_NUM = 10; // should be greater than `vc->state.y - vc->vc_top`
int tty_fd, vcs_fd;
const char *tty_path = "/dev/tty0";
const char *vcs_path = "/dev/vcs";
const char escape_seq[] = "\x1bM"; // ESC + M
const char trigger_seq[] = "Let's trigger an OOB write.";
struct vt_sizes vt_size = { 70, 2 };
int blank = TIOCL_BLANKSCREEN;
tty_fd = open(tty_path, O_RDWR);
char vesa_mode[] = { TIOCL_SETVESABLANK, 1 };
ioctl(tty_fd, TIOCLINUX, vesa_mode);
ioctl(tty_fd, TIOCLINUX, &blank);
ioctl(tty_fd, VT_RESIZE, &vt_size);
for (int i = 0; i < RI_NUM; ++i)
write(tty_fd, escape_seq, sizeof(escape_seq) - 1);
vcs_fd = open(vcs_path, O_RDWR);
write(vcs_fd, trigger_seq, sizeof(trigger_seq));
close(vcs_fd);
close(tty_fd);
return 0;
}
```
To solve this problem, add an address range validation check in
vgacon_scroll(), ensuring vc->vc_origin never precedes vc_screenbuf.

fbdev: arkfb: Cast ics5342_init() allocation type
In preparation for making the kmalloc family of allocators type aware, we need to make sure that the returned type from the allocation matches the type of the variable being assigned. (Before, the allocator would always return "void *", which can be implicitly cast to any pointer type.) The assigned type is "struct dac_info *" but the returned type will be "struct ics5342_info *", which has a larger allocation size. This is by design, as struct ics5342_info contains struct dac_info as its first member.

ring-buffer changes for v6.16:
- Allow the persistent ring buffer to be memory mapped
In the last merge window there was issues with the implementation of
mapping the persistent ring buffer because it was assumed that the
persistent memory was just physical memory without being part of the
kernel virtual address space. But this was incorrect and the persistent
ring buffer can be mapped the same way as the allocated ring buffer is
mapped.
The meta data for the persistent ring buffer is different than the normal
ring buffer and the organization of mapping it to user space is a little
different. Make the updates needed to the meta data to allow the
persistent ring buffer to be mapped to user space.
- Fix cpus_read_lock() with buffer->mutex and cpu_buffer->mapping_lock
Mapping the ring buffer to user space uses the cpu_buffer->mapping_lock.
The buffer->mutex can be taken when the mapping_lock is held, giving the
locking order of: cpu_buffer->mapping_lock -->> buffer->mutex. But there
also exists the ordering:
buffer->mutex -->> cpus_read_lock()
mm->mmap_lock -->> cpu_buffer->mapping_lock
cpus_read_lock() -->> mm->mmap_lock
causing a circular chain of:
cpu_buffer->mapping_lock -> buffer->mutex -->> cpus_read_lock() -->>
mm->mmap_lock -->> cpu_buffer->mapping_lock
By moving the cpus_read_lock() outside the buffer->mutex where:
cpus_read_lock() -->> buffer->mutex, breaks the deadlock chain.
- Do not trigger WARN_ON() for commit overrun
When the ring buffer is user space mapped and there's a "commit overrun"
(where an interrupt preempted an event, and then added so many events it
filled the buffer having to drop events when it hit the preempted event)
a WARN_ON() was triggered if this was read via a memory mapped buffer.
This is due to "missed events" being non zero when the reader page ended
up with the commit page. The idea was, if the writer is on the reader page,
there's only one page that has been written to and there should be no
missed events. But if a commit overrun is done where the writer is off the
commit page and looped around to the commit page causing missed events, it
is possible that the reader page is the commit page with missed events.
Instead of triggering a WARN_ON() when the reader page is the commit page
with missed events, trigger it when the reader page is the tail_page with
missed events. That's because the writer is always on the tail_page if
an event was interrupted (which holds the commit event) and continues off
the commit page.
- Reset the persistent buffer if it is fully consumed
On boot up, if the user fully consumes the last boot buffer of the
persistent buffer, if it reboots without enabling it, there will still be
events in the buffer which can cause confusion. Instead, reset the buffer
when it is fully consumed, so that the data is not read again.
- Clean up some goto out jumps
There's a few cases that the code jumps to the "out:" label that simply
returns a value. There used to be more work done at those labels but now
that they simply return a value use a return instead of jumping to a
label.
- Use guard() to simplify some of the code
Add guard() around some locking instead of jumping to a label to do the
unlocking.
- Use free() to simplify some of the code
Use free(kfree) on variables that will get freed on error and use
return_ptr() to return the variable when its not freed. There's one
instance where free(kfree) simplifies the code on a temp variable that was
allocated just for the function use.

This is a flagday change, thankfully there are very few instances. vfs_submount() is gone - its sole remaining user (trace_automount) had been switched to saner primitives" * tag 'pull-automount' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: kill vfs_submount() saner calling conventions for ->d_automount() |

EFI updates for v6.16
- Add support for emitting a .sbat section into the EFI zboot image, so
that downstreams can easily include revocation metadata in the signed
EFI images
- Align PE symbolic constant names with other projects
- Bug fix for the efi_test module
- Log the physical address and size of the EFI memory map when failing
to map it
- A kerneldoc fix for the EFI stub code

Pull EFI updates from Ard Biesheuvel:
"Not a lot going on in the EFI tree this cycle. The only thing that
stands out is the new support for SBAT metadata, which was a bit
contentious when it was first proposed, because in the initial
incarnation, it would have required us to maintain a revocation index,
and bump it each time a vulnerability affecting UEFI secure boot got
fixed. This was shot down for obvious reasons.
This time, only the changes needed to emit the SBAT section into the
PE/COFF image are being carried upstream, and it is up to the distros
to decide what to put in there when creating and signing the build.
This only has the EFI zboot bits (which the distros will be using for
arm64); the x86 bzImage changes should be arriving next cycle,
presumably via the -tip tree.
Summary:
- Add support for emitting a .sbat section into the EFI zboot image,
so that downstreams can easily include revocation metadata in the
signed EFI images
- Align PE symbolic constant names with other projects
- Bug fix for the efi_test module

I've recently moved computers (among other things) so I'm sending this from a
new machine. The migration process took longer than expected and disrupted my
workflow, but I think I'm ready to go and things should speed up from here.
Luckily, this has been a semi-quiet cycle. The core framework remains unchanged
this time around. In terms of shiny new code though, we have support for the
SpacemiT K1 SoC, Sophgo SG2044, and T-HEAD TH1520 VO clk drivers joining the
usual silicon players like Qualcomm, Samsung, Allwinner, and Renesas.
Surprisingly, the Qualcomm pile was smaller than usual but that is likely
because they put one SoC support inside a driver for a different SoC that is
very similar. Other than all those new clk drivers there are the usual clk data
updates to fix parents, frequency tables, and add missing clks along with some
Kconfig changes to make compile testing simpler and even more DT binding
conversions to boot. The exciting part is still the new SoC support like
SpacemiT and Sophgo support though, which really dominate the diffstat because
they introduce a whole new silicon vendor clk driver.
New Drivers:
- Camera clock controller driver for Qualcomm QCS8300
- DE (display engine) 3.3 clocks on Allwinner H616
- Samsung ExynosAutov920 CPU cluster CL0, CL1 and CL2 clock controllers
- Video Output (VO) subsystem clk controller in the T-HEAD TH1520 SoC
- Clock driver for Sophgo SG2044
- Clock driver for SpacemiT K1 SoC
- Renesas RZ/V2N (R9A09G056) SoC clk driver
Updates:
- Correct data in various SoC clk drivers
- Allow clkaN to be optional in the Qualcomm RPMh clock controller
driver if command db doesn't define it
- Change Kconfig options to not enable by default during compile testing
- Add missing clks in various SoC clk drivers
- Remove some duplicate clk DT bindings and convert some more to YAML

f2fs-for-6.16-rc1
In this round, Matthew converted most of page operations to using folio. Beyond
the work, we've applied some performance tunings such as GC and linear lookup,
in addition to enhancing fault injection and sanity checks.
Enhancement:
- large number of folio conversions
- add a control to turn on/off the linear lookup for performance
- tune GC logics for zoned block device
- improve fault injection and sanity checks
Bug fix:
- handle error cases of memory donation
- fix to correct check conditions in f2fs_cross_rename
- fix to skip f2fs_balance_fs() if checkpoint is disabled
- don't over-report free space or inodes in statvfs
- prevent the current section from being selected as a victim during GC
- fix to calculate first_zoned_segno correctly
- fix to avoid inconsistence in between SIT and SSA for zoned block device
As usual, there are several debugging patches and clean-ups as well.

VFIO updates for v6.16-rc1
- Remove an outdated DMA unmap optimization that relies on a feature
only implemented in AMDv1 page tables. (Jason Gunthorpe)
- Fix various migration issues in the hisi_acc_vfio_pci variant
driver, including use of a wrong DMA address requiring an update to
the migration data structure, resending task completion interrupt
after migration to re-sync queues, fixing a write-back cache
sequencing issue, fixing a driver unload issue, behaving correctly
when the guest driver is not loaded, and avoiding to squash errors
from sub-functions. (Longfang Liu)
- mlx5-vfio-pci variant driver update to make use of the new two-step
DMA API for migration, using a page array directly rather than
using a page list mapped across a scatter list. (Leon Romanovsky)
- Fix an incorrect loop index used when unwinding allocation of dirty
page bitmaps on error, resulting in temporary failure in freeing
unused bitmaps. (Li RongQing)

Restructure the IPMI driver for 6.16
This is a restructure of the IPMI driver, mostly to remove SRCU. The locking had issues, and they were not going to be straightforward to fix. Plus it used tons of memory and was generally a pain. Most of this moves handling of messages out of bh and interrupt context and runs it in thread context. Then getting rid of SRCU is easy.

provided by the architecture's TEE Security Manager. Use it to publish
TDX "Runtime Measurement Registers" ("RTMRs") that either maintain a
hash of stored values (similar to a TPM PCR) or provide statically
provisioned data. These measurements are validated by a relying party.
- Reorganize the drivers/virt/coco/ directory for "host" and "guest"
shared infrastructure.
- Fix a configfs-tsm-report unregister bug

tracing updates for v6.16:
- Have module addresses get updated in the persistent ring buffer The addresses of the modules from the previous boot are saved in the persistent ring buffer. If the same modules are loaded and an address is in the old buffer points to an address that was both saved in the persistent ring buffer and is loaded in memory, shift the address to point to the address that is loaded in memory in the trace event. - Print function names for irqs off and preempt off callsites When ignoring the print fmt of a trace event and just printing the fields directly, have the fields for preempt off and irqs off events still show the function name (via kallsyms) instead of just showing the raw address. - Clean ups of the histogram code The histogram functions saved over 800 bytes on the stack to process events as they come in. Instead, create per-cpu buffers that can hold this information and have a separate location for each context level (thread, softirq, IRQ and NMI). Also add some more comments to the code. - Add "common_comm" field for histograms Add "common_comm" that uses the current->comm as a field in an event histogram and acts like any of the other fields of the event. - Show "subops" in the enabled_functions file When the function graph infrastructure is used, a subsystem has a "subops" that it attaches its callback function to. Instead of the enabled_functions just showing a function calling the function that calls the subops functions, also show the subops functions that will get called for that function too. - Add "copy_trace_marker" option to instances There are cases where an instance is created for tooling to write into, but the old tooling has the top level instance hardcoded into the application. New tools want to consume the data from an instance and not the top level buffer. By adding a copy_trace_marker option, whenever the top instance trace_marker is written into, a copy of it is also written into the instance with this option set. This allows new tools to read what old tools are writing into the top buffer. If this option is cleared by the top instance, then what is written into the trace_marker is not written into the top instance. This is a way to redirect the trace_marker writes into another instance. - Have tracepoints created by DECLARE_TRACE() use trace_<name>_tp() If a tracepoint is created by DECLARE_TRACE() instead of TRACE_EVENT(), then it will not be exposed via tracefs. Currently there's no way to differentiate in the kernel the tracepoint functions between those that are exposed via tracefs or not. A calling convention has been made manually to append a "_tp" prefix for events created by DECLARE_TRACE(). Instead of doing this manually, force it so that all DECLARE_TRACE() events have this notation. - Use __string() for task->comm in some sched events Instead of hardcoding the comm to be TASK_COMM_LEN in some of the scheduler events use __string() which makes it dynamic. Note, if these events are parsed by user space it they may break, and the event may have to be converted back to the hardcoded size. - Have function graph "depth" be unsigned to the user Internally to the kernel, the "depth" field of the function graph event is signed due to -1 being used for end of boundary. What actually gets recorded in the event itself is zero or positive. Reflect this to user space by showing "depth" as unsigned int and be consistent across all events. - Allow an arbitrary long CPU string to osnoise_cpus_write() The filtering of which CPUs to write to can exceed 256 bytes. If a machine has 256 CPUs, and the filter is to filter every other CPU, the write would take a string larger than 256 bytes. Instead of using a fixed size buffer on the stack that is 256 bytes, allocate it to handle what is passed in. - Stop having ftrace check the per-cpu data "disabled" flag The "disabled" flag in the data structure passed to most ftrace functions is checked to know if tracing has been disabled or not. This flag was added back in 2008 before the ring buffer had its own way to disable tracing. The "disable" flag is now not always set when needed, and the ring buffer flag should be used in all locations where the disabled is needed. Since the "disable" flag is redundant and incorrect, stop using it. Fix up some locations that use the "disable" flag to use the ring buffer info. - Use a new tracer_tracing_disable/enable() instead of data->disable flag There's a few cases that set the data->disable flag to stop tracing, but this flag is not consistently used. It is also an on/off switch where if a function set it and calls another function that sets it, the called function may incorrectly enable it. Use a new trace_tracing_disable() and tracer_tracing_enable() that uses a counter and can be nested. These use the ring buffer flags which are always checked making the disabling more consistent. - Save the trace clock in the persistent ring buffer Save what clock was used for tracing in the persistent ring buffer and set it back to that clock after a reboot. - Remove unused reference to a per CPU data pointer in mmiotrace functions - Remove unused buffer_page field from trace_array_cpu structure - Remove more strncpy() instances - Other minor clean ups and fixes -----BEGIN PGP SIGNATURE----- iIoEABYKADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCaDhiqRQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qkheAQDpyRHoXF1AIoEqyahDax8f3vpZQeCH B/mn+YJmU1wuVgEA7AFALov5SHKv4IzoARz68GXtR0jGhP5D8uebUhUqDAQ= =WmFG -----END PGP SIGNATURE----- Merge tag 'trace-v6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing updates from Steven Rostedt: - Have module addresses get updated in the persistent ring buffer The addresses of the modules from the previous boot are saved in the persistent ring buffer.

Instead have the tool return an error status if it exceeds the threadhold. - Define __NR_sched_setattr for LoongArch Define __NR_sched_setattr to allow this to build for LoongArch. - Define _GNU_SOURCE for timerlat_bpf.c Due to modifications of struct sched_attr in utils.h when _GNU_SOURCE is not defined, this can cause errors for timerlat_bpf_init() and breakage in BPF sample collection mode. -----BEGIN PGP SIGNATURE----- iIoEABYKADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCaDeTzBQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qokRAP0XJzos+uvQtkGrqiX5SB/rn1s3/tiD nZagARyiV06BAwEA+NNzqFyx/BLUwMnpx/HFTnIMGXbRVWCVAEeL3t77zgk= =dx7t -----END PGP SIGNATURE----- Merge tag 'trace-tools-v6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing tools updates from Steven Rostedt: - Set distinctive value for failed tests When running "make check" that performs tests on rtla the failure is checked by examining the output.
