This indicates that the pgoff is unaligned.  After analysis, I confirm the
vma is mapped to /dev/zero.  Such a vma certainly has vm_file, but it is
set to anonymous by mmap_zero().  So even if it's mmapped by 2m-unaligned,
it can pass the check in thp_vma_allowable_order() as it is an
anonymous-mmap, but then be collapsed as a file-mmap.

It seems the problem has existed for a long time, but actually, since we
have khugepaged_max_ptes_none check before, we will skip collapse it as it
is /dev/zero and so has no present page.  But commit d8ea7cc854 limit
the check for only khugepaged, so the BUG_ON() can be triggered by
madvise_collapse().

Add vma_is_anonymous() check to make such vma be processed by
hpage_collapse_scan_pmd().

c60f5156e6 KVM: x86: Free vCPUs before freeing VM state
commit 17bcd71442 upstream.

Free vCPUs before freeing any VM state, as both SVM and VMX may access
VM state when "freeing" a vCPU that is currently "in" L2, i.e. that needs
to be kicked out of nested guest mode.

Commit 6fcee03df6 ("KVM: x86: avoid loading a vCPU after .vm_destroy was
called") partially fixed the issue, but for unknown reasons only moved the
MMU unloading before VM destruction.  Complete the change, and free all
vCPU state prior to destroying VM state, as nVMX accesses even more state
than nSVM.

In addition to the AVIC, KVM can hit a use-after-free on MSR filters:

and an upcoming fix to process injectable interrupts on nested VM-Exit
will access the PIC:

   kvm_destroy_vm+0x172/0x300 [kvm]
   kvm_vcpu_release+0x31/0x50 [kvm]

Inarguably, both nSVM and nVMX need to be fixed, but punt on those
cleanups for the moment.  Conceptually, vCPUs should be freed before VM
state.  Assets like the I/O APIC and PIC _must_ be allocated before vCPUs
are created, so it stands to reason that they must be freed _after_ vCPUs
are destroyed.

69fbb3f174 drm/i915/dp: Fix 2.7 Gbps DP_LINK_BW value on g4x
commit 9e0c433d0c upstream.

On g4x we currently use the 96MHz non-SSC refclk, which can't actually
generate an exact 2.7 Gbps link rate. In practice we end up with 2.688
Gbps which seems to be close enough to actually work, but link training
is currently failing due to miscalculating the DP_LINK_BW value (we
calcualte it directly from port_clock which reflects the actual PLL
outpout frequency).

Ideas how to fix this:
- nudge port_clock back up to 270000 during PLL computation/readout
- track port_clock and the nominal link rate separately so they might
  differ a bit
- switch to the 100MHz refclk, but that one should be SSC so perhaps
  not something we want

While we ponder about a better solution apply some band aid to the
immediate issue of miscalculated DP_LINK_BW value. With this
I can again use 2.7 Gbps link rate on g4x.

c7f864d345 Drivers: hv: Make the sysfs node size for the ring buffer dynamic
commit 65995e97a1 upstream.

The ring buffer size varies across VMBus channels. The size of sysfs
node for the ring buffer is currently hardcoded to 4 MB. Userspace
clients either use fstat() or hardcode this size for doing mmap().
To address this, make the sysfs node size dynamic to reflect the
actual ring buffer size for each channel. This will ensure that
fstat() on ring sysfs node always returns the correct size of
ring buffer.

beddf74e40 ARM: 9448/1: Use an absolute path to unified.h in KBUILD_AFLAGS
[ Upstream commit 87c4e1459e ]

After commit d5c8d6e0fa ("kbuild: Update assembler calls to use proper
flags and language target"), which updated as-instr to use the
'assembler-with-cpp' language option, the Kbuild version of as-instr
always fails internally for arch/arm with

  <command-line>: fatal error: asm/unified.h: No such file or directory
  compilation terminated.

because '-include' flags are now taken into account by the compiler
driver and as-instr does not have '$(LINUXINCLUDE)', so unified.h is not
found.

This went unnoticed at the time of the Kbuild change because the last
use of as-instr in Kbuild that arch/arm could reach was removed in 5.7
by commit 541ad0150c ("arm: Remove 32bit KVM host support") but a
stable backport of the Kbuild change to before that point exposed this
potential issue if one were to be reintroduced.

Follow the general pattern of '-include' paths throughout the tree and
make unified.h absolute using '$(srctree)' to ensure KBUILD_AFLAGS can
be used independently.

3d12349ade x86/hyperv: Fix APIC ID and VP index confusion in hv_snp_boot_ap()
[ Upstream commit 86c48271e0 ]

To start an application processor in SNP-isolated guest, a hypercall
is used that takes a virtual processor index. The hv_snp_boot_ap()
function uses that START_VP hypercall but passes as VP index to it
what it receives as a wakeup_secondary_cpu_64 callback: the APIC ID.

As those two aren't generally interchangeable, that may lead to hung
APs if the VP index and the APIC ID don't match up.

Update the parameter names to avoid confusion as to what the parameter
is. Use the APIC ID to the VP index conversion to provide the correct
input to the hypercall.

f1b3ad11ec KVM: x86/hyper-v: Skip non-canonical addresses during PV TLB flush
[ Upstream commit fa787ac07b ]

In KVM guests with Hyper-V hypercalls enabled, the hypercalls
HVCALL_FLUSH_VIRTUAL_ADDRESS_LIST and HVCALL_FLUSH_VIRTUAL_ADDRESS_LIST_EX
allow a guest to request invalidation of portions of a virtual TLB.
For this, the hypercall parameter includes a list of GVAs that are supposed
to be invalidated.

However, when non-canonical GVAs are passed, there is currently no
filtering in place and they are eventually passed to checked invocations of
INVVPID on Intel / INVLPGA on AMD.  While AMD's INVLPGA silently ignores
non-canonical addresses (effectively a no-op), Intel's INVVPID explicitly
signals VM-Fail and ultimately triggers the WARN_ONCE in invvpid_error():

  invvpid failed: ext=0x0 vpid=1 gva=0xaaaaaaaaaaaaa000
  WARNING: CPU: 6 PID: 326 at arch/x86/kvm/vmx/vmx.c:482
  invvpid_error+0x91/0xa0 [kvm_intel]

  CPU: 6 UID: 0 PID: 326 Comm: kvm-vm Not tainted 6.15.0 #14 PREEMPT(voluntary)

    kvm_hv_vcpu_flush_tlb+0x24f/0x4f0 [kvm]
    kvm_arch_vcpu_ioctl_run+0x3013/0x5810 [kvm]

Hyper-V documents that invalid GVAs (those that are beyond a partition's
GVA space) are to be ignored.  While not completely clear whether this
ruling also applies to non-canonical GVAs, it is likely fine to make that
assumption, and manual testing on Azure confirms "real" Hyper-V interprets
the specification in the same way.

Skip non-canonical GVAs when processing the list of address to avoid
tripping the INVVPID failure.  Alternatively, KVM could filter out "bad"
GVAs before inserting into the FIFO, but practically speaking the only
downside of pushing validation to the final processing is that doing so
is suboptimal for the guest, and no well-behaved guest will request TLB
flushes for non-canonical addresses.

d483bf624f KVM: x86: model canonical checks more precisely
[ Upstream commit 9245fd6b85 ]

As a result of a recent investigation, it was determined that x86 CPUs
which support 5-level paging, don't always respect CR4.LA57 when doing
canonical checks.

In particular:

1. MSRs which contain a linear address, allow full 57-bitcanonical address
regardless of CR4.LA57 state. For example: MSR_KERNEL_GS_BASE.

2. All hidden segment bases and GDT/IDT bases also behave like MSRs.
This means that full 57-bit canonical address can be loaded to them
regardless of CR4.LA57, both using MSRS (e.g GS_BASE) and instructions
(e.g LGDT).

3. TLB invalidation instructions also allow the user to use full 57-bit
address regardless of the CR4.LA57.

Finally, it must be noted that the CPU doesn't prevent the user from
disabling 5-level paging, even when the full 57-bit canonical address is
present in one of the registers mentioned above (e.g GDT base).

In fact, this can happen without any userspace help, when the CPU enters
SMM mode - some MSRs, for example MSR_KERNEL_GS_BASE are left to contain
a non-canonical address in regard to the new mode.

Since most of the affected MSRs and all segment bases can be read and
written freely by the guest without any KVM intervention, this patch makes
the emulator closely follow hardware behavior, which means that the
emulator doesn't take in the account the guest CPUID support for 5-level
paging, and only takes in the account the host CPU support.

33f61ecabb ext4: refactor ext4_punch_hole()
[ Upstream commit 982bf37da0 ]

The current implementation of ext4_punch_hole() contains complex
position calculations and stale error tags. To improve the code's
clarity and maintainability, it is essential to clean up the code and
improve its readability, this can be achieved by: a) simplifying and
renaming variables; b) eliminating unnecessary position calculations;
c) writing back all data in data=journal mode, and drop page cache from
the original offset to the end, rather than using aligned blocks,
d) renaming the stale error tags.

After commit 'ad5cd4f4ee4d ("ext4: fix fallocate to use file_modified to
update permissions consistently"), we can update mtime and ctime
appropriately through file_modified() when doing zero range, collapse
rage, insert range and punch hole, hence there is no need to explicit
update times in those paths, just drop them.

a5ae7fa30c erofs: fix large fragment handling
[ Upstream commit b44686c839 ]

Fragments aren't limited by Z_EROFS_PCLUSTER_MAX_DSIZE. However, if
a fragment's logical length is larger than Z_EROFS_PCLUSTER_MAX_DSIZE
but the fragment is not the whole inode, it currently returns
-EOPNOTSUPP because m_flags has the wrong EROFS_MAP_ENCODED flag set.
It is not intended by design but should be rare, as it can only be
reproduced by mkfs with `-Eall-fragments` in a specific case.

Let's normalize fragment m_flags using the new EROFS_MAP_FRAGMENT.

`Z_EROFS_ADVISE_INLINE_PCLUSTER` cannot be ignored, as `h_idata_size`

Additionally, merge `z_idataoff` and `z_fragmentoff` since these two

 - Set `compressedblks = 1` directly for non-bigpcluster cases.  This
   simplifies the logic a bit since lcluster sizes larger than one block
   are unsupported and the details remain unclear.

 - For Z_EROFS_LCLUSTER_TYPE_PLAIN pclusters, avoid assuming

   Z_EROFS_ADVISE_BIG_PCLUSTER_2 is set.

It basically has no impact to existing valid images, but it's useful to
find the gap to prepare for large PLAIN pclusters.

[ Upstream commit 47bddabbf6 ]

For QPIC V2 onwards there is a separate register to read
last code word "QPIC_NAND_READ_LOCATION_LAST_CW_n".

qcom_param_page_type_exec() is used to read only one code word
If it configures the number of code words to 1 in QPIC_NAND_DEV0_CFG0
register then QPIC controller thinks its reading the last code word,
since we are having separate register to read the last code word,
we have to configure "QPIC_NAND_READ_LOCATION_LAST_CW_n" register
to fetch data from QPIC buffer to system memory.

Without this change page read was failing with timeout error

b49b543f4e comedi: comedi_test: Fix possible deletion of uninitialized timers
commit 1b98304c09 upstream.

In `waveform_common_attach()`, the two timers `&devpriv->ai_timer` and
`&devpriv->ao_timer` are initialized after the allocation of the device
private data by `comedi_alloc_devpriv()` and the subdevices by
`comedi_alloc_subdevices()`.  The function may return with an error
between those function calls.  In that case, `waveform_detach()` will be
called by the Comedi core to clean up.  The check that
`waveform_detach()` uses to decide whether to delete the timers is
incorrect.  It only checks that the device private data was allocated,
but that does not guarantee that the timers were initialized.  It also
needs to check that the subdevices were allocated.  Fix it.

commit bec15191d5 upstream.

This patch fixes Type-C compliance test TD 4.7.6 - Try.SNK DRP Connect
SNKAS.

tVbusON has a limit of 275ms when entering SRC_ATTACHED. Compliance
testers can interpret the TryWait.Src to Attached.Src transition after
Try.Snk as being in Attached.Src the entire time, so ~170ms is lost
to the debounce timer.

Setting the data role can be a costly operation in host mode, and when
completed after 100ms can cause Type-C compliance test check TD 4.7.5.V.4
to fail.

Turn VBUS on before tcpm_set_roles to meet timing requirement.
