0e875ee5e8 remoteproc updates for v6.9 
Qualcomm SM8650 audio, compute and modem remoteproc are added. Qualcomm
 X1 Elite audio and compute remoteprocs are added, after support for
 shutting down the bootloader-loaded firmware loaded into the audio DSP..
 
 A dozen drivers in the subsystem are transitioned to use devres helpers
 for remoteproc and memory allocations.
 
 It makes it possible to acquire in-kernel handle to individual
 remoteproc instances in a cluster.
 
 The release of DMA memory for remoteproc virtio is corrected to ensure
 that restarting due to a watchdog bite doesn't attempt to allocate the
 memory again without first freeing it.
 
 Last, but not least, a couple of DeviceTree binding cleanups.

bfb1ad3c6a firewire: core: add memo about the caller of show functions for device attributes 
In the case of firewire core function, the caller of show functions for
device attributes is not only sysfs user, but also device initialization.

This commit adds memo about it against the typical assumption that the
functions are just dedicated to sysfs user.

42c2a75694 Updates to tools/tracing and verification for 6.9: 
Tracing:
 
 - Update makefiles for latency-collector and RTLA, using tools/build/
   makefiles like perf does, inheriting its benefits. For example, having a
   proper way to handle library dependencies.
 
 - The timerlat tracer has an interface for any tool to use.  rtla timerlat
   tool uses this interface dispatching its own threads as workload. But,
   rtla timerlat could also be used for any other process. So, add 'rtla
   timerlat -U' option, allowing the timerlat tool to measure the latency of
   any task using the timerlat tracer interface.
 
 Verification:
 
 - Update makefiles for verification/rv, using tools/build/ makefiles like
   perf does, inheriting its benefits.  For example, having a proper way to
   handle dependencies.

f2fd2aad19 kconfig: tests: test dependency after shuffling choices 
Commit c8fb7d7e48 ("kconfig: fix broken dependency in randconfig-
generated .config") fixed the issue, but I did not add a test case.

This commit adds a test case that emulates the reported situation.
The test would fail without c8fb7d7e48.

To handle the choice "choose X", FOO must be calculated beforehand.
FOO depends on A, which is a member of another choice "choose A or B".
Kconfig _temporarily_ assumes the value of A to proceed. The choice
"choose A or B" will be shuffled later, but the result may or may not
meet "FOO depends on A". Kconfig should invalidate the symbol values
and recompute them.

In the real example for ARCH=arm64, the choice "Instrumentation type"
needs the value of CPU_BIG_ENDIAN. The choice "Endianness" will be
shuffled later.

47ad16894c kconfig: tests: add a test for randconfig with dependent choices 
Since commit 3b9a19e089 ("kconfig: loop as long as we changed some
symbols in randconfig"), conf_set_all_new_symbols() is repeated until
there is no more choice left to be shuffled. The motivation was to
shuffle a choice nested in another choice.

Although commit 09d5873e4d ("kconfig: allow only 'config', 'comment',
and 'if' inside 'choice'") disallowed the nested choice structure,
we must still keep 3b9a19e089 because there are still cases where
conf_set_all_new_symbols() must iterate.

scripts/kconfig/tests/choice_randomize/Kconfig is the test case.
The second choice depends on 'B', which is the member of the first
choice.

With 3b9a19e089 reverted, we would never get the pattern specified by
scripts/kconfig/tests/choice_randomize/expected_config2.

A real example can be found in lib/Kconfig.debug. Without 3b9a19e089,
the randconfig would not shuffle the "Compressed Debug information"
choice, which depends on DEBUG_INFO, which is derived from another
choice "Debug information".

My goal is to refactor Kconfig so that randconfig will work more
simply, without using the loop.

For now, let's add a test case to ensure all dependent choices are
shuffled, as it is a somewhat tricky case for the current Kconfig.

a23c05fd76 tools/rtla: Add -U/--user-load option to timerlat 
The timerlat tracer provides an interface for any application to wait
for the timerlat's periodic wakeup. Currently, rtla timerlat uses it
to dispatch its user-space workload (-u option).

But as the tracer interface is generic, rtla timerlat can also be used
to monitor any workload that uses it. For example, a user might
place their own workload to wait on the tracer interface, and
monitor the results with rtla timerlat.

Add the -U option to rtla timerlat top and hist. With this option, rtla
timerlat will not dispatch its workload but only setting up the
system, waiting for a user to dispatch its workload.

The sample code in this patch is an example of python application
that loops in the timerlat tracer fd.

To use it, dispatch:

 # rtla timerlat -U

In a terminal, then run the python program on another terminal,
specifying the CPU to run it. For example, setting on CPU 1:

 #./timerlat_load.py 1

Then rtla timerlat will start printing the statistics of the
./timerlat_load.py app.

An interesting point is that the "Ret user Timer Latency" value
is the overall response time of the load. The sample load does
a memory copy to exemplify that.

The stop tracing options on rtla timerlat works in this setup
as well, including auto analysis.

01474dc706 tools/rtla: Use tools/build makefiles to build rtla 
Use tools/build/ makefiles to build rtla, inheriting the benefits of
it. For example, having a proper way to handle dependencies.

rtla is built using perf infra-structure when building inside the
kernel tree.

At this point, rtla diverges from perf in two points: Documentation
and tarball generation/build.

At the documentation level, rtla is one step ahead, placing the
documentation at Documentation/tools/rtla/, using the same build
tools as kernel documentation. The idea is to move perf
documentation to the same scheme and then share the same makefiles.

rtla has a tarball target that the (old) RHEL8 uses. The tarball was
kept using a simple standalone makefile for compatibility. The
standalone makefile shares most of the code, e.g., flags, with
regular buildings.

The tarball method was set as deprecated. If necessary, we can make
a rtla tarball like perf, which includes the entire tools/build.
But this would also require changes in the user side (the directory
structure changes, and probably the deps to build the package).

Inspired on perf and objtool.

f9c035492f more s390 updates for 6.9 merge window 
- Various virtual vs physical address usage fixes
 
 - Add new bitwise types and helper functions and use them in s390 specific
   drivers and code to make it easier to find virtual vs physical address
   usage bugs. Right now virtual and physical addresses are identical for
   s390, except for module, vmalloc, and similar areas. This will be
   changed, hopefully with the next merge window, so that e.g. the kernel
   image and modules will be located close to each other, allowing for
   direct branches and also for some other simplifications.
 
   As a prerequisite this requires to fix all misuses of virtual and
   physical addresses. As it turned out people are so used to the concept
   that virtual and physical addresses are the same, that new bugs got added
   to code which was already fixed. In order to avoid that even more code
   gets merged which adds such bugs add and use new bitwise types, so that
   sparse can be used to find such usage bugs.
 
   Most likely the new types can go away again after some time
 
 - Provide a simple ARCH_HAS_DEBUG_VIRTUAL implementation
 
 - Fix kprobe branch handling: if an out-of-line single stepped relative
   branch instruction has a target address within a certain address area in
   the entry code, the program check handler may incorrectly execute cleanup
   code as if KVM code was executed, leading to crashes
 
 - Fix reference counting of zcrypt card objects
 
 - Various other small fixes and cleanups

 - Add new bitwise types and helper functions and use them in s390
   specific drivers and code to make it easier to find virtual vs
   physical address usage bugs.

   Right now virtual and physical addresses are identical for s390,
   except for module, vmalloc, and similar areas. This will be changed,
   hopefully with the next merge window, so that e.g. the kernel image
   and modules will be located close to each other, allowing for direct
   branches and also for some other simplifications.

   As a prerequisite this requires to fix all misuses of virtual and
   physical addresses. As it turned out people are so used to the
   concept that virtual and physical addresses are the same, that new
   bugs got added to code which was already fixed. In order to avoid
   that even more code gets merged which adds such bugs add and use new
   bitwise types, so that sparse can be used to find such usage bugs.

   Most likely the new types can go away again after some time

 - Provide a simple ARCH_HAS_DEBUG_VIRTUAL implementation

 - Fix kprobe branch handling: if an out-of-line single stepped relative
   branch instruction has a target address within a certain address area
   in the entry code, the program check handler may incorrectly execute
   cleanup code as if KVM code was executed, leading to crashes

 - Fix reference counting of zcrypt card objects

 - Various other small fixes and cleanups

24f5bb9f24 tracing: Just use strcmp() for testing __string() and __assign_str() match 
As __assign_str() no longer uses its "src" parameter, there's a check to
make sure nothing depends on it being different than what was passed to
__string(). It originally just compared the pointer passed to __string()
with the pointer passed into __assign_str() via the "src" parameter. But
there's a couple of outliers that just pass in a quoted string constant,
where comparing the pointers is UB to the compiler, as the compiler is
free to create multiple copies of the same string constant.

Instead, just use strcmp(). It may slow down the trace event, but this
will eventually be removed.

Also, fix the issue of passing NULL to strcmp() by adding a WARN_ON() to
make sure that both "src" and the pointer saved in __string() are either
both NULL or have content, and then checking if "src" is not NULL before
performing the strcmp().

- A single fix for ASMedia HBAs.
    These HBAs do not indicate that they support SATA Port Multipliers
    CAP.SPM (Supports Port Multiplier) is not set.
 
    Likewise, they do not allow you to probe the devices behind an
    attached PMP, as defined according to the SATA-IO PMP specification.
 
    Instead, they have decided to implement their own version of PMP,
    and because of this, plugging in a PMP actually works, even if the
    HBA claims that it does not support PMP.
 
    Revert a recent quirk for these HBAs, as that breaks ASMedia's own
    implementation of PMP.
 
    Unfortunately, this will once again give some users of these HBAs
    significantly increased boot time. However, a longer boot time for
    some, is the lesser evil compared to some other users not being able
    to detect their drives at all.

96cf51accc exfat: do not sync parent dir if just update timestamp 
When sync or dir_sync is enabled, there is no need to sync the
parent directory's inode if only for updating its timestamp.

1. If an unexpected power failure occurs, the timestamp of the
   parent directory is not updated to the storage, which has no
   impact on the user.

2. The number of writes will be greatly reduced, which can not
   only improve performance, but also prolong device life.

af02c72d0b exfat: convert exfat_find_empty_entry() to use dentry cache 
Before this conversion, each dentry traversed needs to be read
from the storage device or page cache. There are at least 16
dentries in a sector. This will result in frequent page cache
searches.

After this conversion, if all directory entries in a sector are
used, the sector only needs to be read once.

d97e060673 exfat: convert exfat_init_ext_entry() to use dentry cache 
Before this conversion, in exfat_init_ext_entry(), to init
the dentries in a dentry set, the sync times is equals the
dentry number if 'dirsync' or 'sync' is enabled.
That affects not only performance but also device life.

After this conversion, only needs to be synchronized once if
'dirsync' or 'sync' is enabled.

4e1aa22fea exfat: move free cluster out of exfat_init_ext_entry() 
exfat_init_ext_entry() is an init function, it's a bit strange
to free cluster in it. And the argument 'inode' will be removed
from exfat_init_ext_entry(). So this commit changes to free the
cluster in exfat_remove_entries().

Code refinement, no functional changes.
