My previous patch to prevent BPMP from being enabled on big
endian kernels caused a build regression:
WARNING: unmet direct dependencies detected for TEGRA_BPMP
Depends on [n]: ARCH_TEGRA [=y] && TEGRA_HSP_MBOX [=y] && TEGRA_IVC [=y] && !CPU_BIG_ENDIAN [=y]
Selected by [y]:
- ARCH_TEGRA_186_SOC [=y] && ARCH_TEGRA [=y] && ARM64 [=y]
- ARCH_TEGRA_194_SOC [=y] && ARCH_TEGRA [=y] && ARM64 [=y]
- ARCH_TEGRA_234_SOC [=y] && ARCH_TEGRA [=y] && ARM64 [=y]
Add even more such dependencies for the SoC types that use
the BPMP driver.
Fixes: 4ddb1bf1a837 ("tegra: mark BPMP driver as little-endian only")

lld cannot build for ARMv4/v4T targets because it inserts 'blx' instructions
that are unsupported there:
ld.lld: warning: lld uses blx instruction, no object with architecture supporting feature detected
Add a Kconfig time dependency to prevent those targets from being
selected in randconfig builds.

The integrated assembler in clang does not understand the xscale
specific mra/mar instructions:
arch/arm/mach-pxa/pxa27x.c:136:15: error: unsupported architectural extension: xscale
asm volatile(".arch_extension xscale\n\t"
arch/arm/mach-pxa/pxa27x.c:136:40: error: invalid instruction, did you mean: mcr, mla, mrc, mrs, msr?
mra r2, r3, acc0
Since these are coprocessor features, the same can be expressed using
mrrc/mcrr, so use that for builds with IAS.

Pull more nfsd updates from Chuck Lever:
"This contains a number of crasher fixes that were not ready for the
initial pull request last week.
In particular, Jeff's patch attempts to address reference count
underflows in NFSD's filecache, which have been very difficult to
track down because there is no reliable reproducer.
Common failure modes:
https://bugzilla.kernel.org/show_bug.cgi?id=216691#c11
https://bugzilla.kernel.org/show_bug.cgi?id=216674#c6
https://bugzilla.redhat.com/show_bug.cgi?id=2138605
The race windows were found by inspection and the clean-ups appear
sensible and pass regression testing, so we include them here in the
hope that they address the problem. However we remain vigilant because
we don't have 100% certainty yet that the problem is fully addressed.
Summary:
- Address numerous reports of refcount underflows in NFSD's filecache
- Address a UAF in callback setup error handling
- Address a UAF during server-to-server copy"

Pull MSI fixes from Marc Zyngier:
"Thomas tasked me with sending out a few urgent fixes after the giant
MSI rework that landed in 6.2, as both s390 and powerpc ended-up
suffering from it (they do not use the full core code infrastructure,
leading to these previously undetected issues):
- Return MSI_XA_DOMAIN_SIZE as the maximum MSI index when the
architecture does not make use of irq domains instead of returning
0, which is pretty limiting.
- Check for the presence of an irq domain when validating the MSI
iterator, as s390/powerpc won't have one.
- Fix powerpc's MSI backends which fail to clear the descriptor's IRQ
field on teardown, leading to a splat and leaked descriptors"

Since 2f2940d16823 ("genirq/msi: Remove filter from
msi_free_descs_free_range()"), the core MSI code relies on the
msi_desc->irq field to have been cleared before the descriptor
can be freed, as it indicates that there is no association with
a device anymore.
The irq domain code provides this guarantee, and so does s390,
which is one of the two architectures not using irq domains for
MSIs.
Powerpc, however, is missing this particular requirements,
leading in a splat and leaked MSI descriptors.
Adding the now required irq reset to the handful of powerpc backends
that implement MSIs fixes that particular problem.

Pull perf tools updates from Arnaldo Carvalho de Melo:
"Libraries:
- Drop the old copy of libtraceevent in tools/lib/traceevent/ now
that all major distros ship it from its external repository.
This is now just another feature detection, emitting a warning when
the libtraceevent-dev[el] package isn't installed, disabling the
build of perf features and tools that strictly require parsing
things from tracefs while keeping the core functionality present
and working with a subset of the events, the most used ones like
CPU cycles, hardware cache and also vendor events, etc.
This was tested with lots of containers for Fedora, Debian,
OpenSUSE, Alpine Linux, Ubuntu, with cross builds, etc.
Build:
- Update to C standard to gnu11, like was done for the kernel.
- Install the tools/lib/ libraries locally instead of having headers
searched directly from the source code directories, to help the
cases where we can build either from in-kernel source libraries or
from the same library shipped as a distro package, as is the case
with libbpf and was the case with libtraceevent.
perf stat:
- Do not delay the workload with --delay, the delay is just for
starting to count the events, to skip noise at workload startup.
- When we have events for each cgroup, the metric should be printed
for each cgroup separately.
$ perf stat -a --for-each-cgroup system.slice,user.slice --metric-only sleep 1
Performance counter stats for 'system wide':
GHz insn per cycle branch-misses of all branches
system.slice 3.792 0.61 3.24%
user.slice 3.661 2.32 0.37%
- Fix printing field separator in CSV metrics output.
- Fix --metric-only --json output.
- Fix summary output in CSV with --metric-only.
- Update event group check for support of uncore event.
perf test:
- Stop requiring a C toolchain in shell tests, instead add a workload
option that has all the previously C snippets built as part of
'perf test -w' that then get used in the 'perf test' shell scripts.
- Add event group test for events in multiple PMUs
- The "kernel lock contention analysis" test should not print
warnings in quiet mode.
- Add attr tests for ARM64's new VG register.
- Fix record test on KVM guests, as using precise flag with the
br_inst_retired.near_call event causes the test fail on KVM guests,
even when the guests have PMU forwarding enabled and the event
itself is supported, so just remove the precise flag from the
event.
- Add mechanism for skipping attr tests on specific kernel versions
where it is known that these checks will fail.
- Skip watchpoint tests if no watchpoints available.
- Add more Intel PT 'perf test' entries: hybrid CPUs, split the
packet decoder into a suite of subtests.
perf script:
- Introduce task analyzer python script, where one first records some events:
Recording can be done in two ways:
$ perf script record tasks-analyzer -- sleep 10
$ perf record -e sched:sched_switch -a -- sleep 10
The script can parse any perf.data files, as long as it has
sched:sched_switch events, other events will be ignored.
The most simple report use case is to just call the script without
arguments.
Runtime is the time the task was running on the CPU, Time Out-In is
the time between the process being scheduled *out* and scheduled
back *in*. So the last time span between two executions:
$ perf script report tasks-analyzer
Switched-In Switched-Out CPU PID TID Comm Runtime Time Out-In

perf record:
- Add remaining branch filters: "no_cycles", "no_flags" & "hw_index",
to be used with hardware such as Intel's LBR that allows things
like stitching stacks of two samples to overcome the limits of the
number of LBR registers.
Symbol resolution:
- Handle .debug files created with 'objcopy --only-keep-debug', where
program headers are zeroed and thus can't be used for adjustments,
use the info in the runtime_ss (runtime ELF) instead.
perf trace:
- Add BPF based augmenter for the 'perf_event_open's 'struct
perf_event_attr' argument.
- Add BPF based augmenter for the 'clock_gettime's 'struct timespec'
argument.
- In both cases the syscall tracepoint has just the pointer value, we
need to hook a BPF program to collect the pointer contents, and
then, in userspace, pretty print it in 'perf trace'.
perf list:
- Introduce JSON output of events.
- Streamline how the expression specifying what events should be
shown is handled, fixing several corner cases, such as the metric
filter that is specified as a glob but was using strstr().
perf probe:
- Fix to avoid crashing if DW_AT_decl_file is NULL, coping with clang
generating DWARF5 like that.
- Use dwarf_attr_integrate() as generic DWARF attr accessor as it
supersedes dwarf_attr(), supporting abstact origin DIEs.
perf inject:
- Set PERF_RECORD_MISC_BUILD_ID_SIZE in the PERF_RECORD_HEADER_BUILD_ID
so that perf.data readers can get the real build-id size and avoid
trailing zeroes.
perf data:
- Add tracepoint fields when converting a perf.data file to JSON.
arm64:
- Fix mksyscalltbl, don't lose syscalls due to sort -nu.
- Add Arm Neoverse V2 PMU events.
riscv:
- Add riscv sbi firmware std event files.
- Add Sifive U74 vendor events (JSON) file.
- Add some more events and metrics for Alderlake/Alderlake-N.
Documentation:
- Add data documentation for the PMU structs in the C source code.
Miscellaneous:
- Periodic sanitization of headers, adding missing includes, removing
needless ones, creating new ones, etc.
- Use sig_atomic_t for signal handlers to avoid undefined behaviour
in all perf tools.
- Fixes for libbpf 1.0+ compatibility (maps, etc) on 'perf trace' BPF
examples.
- Remove some old perf bpf examples, leave the best ones that
demonstrate how to associate BPF functions to points in the kernel.
- Make quiet mode consistent between tools.
- Use dedicated non-atomic clear/set bit helpers.
- Use "grep -E" instead of "egrep" as recommended by warning emitted
by GNU grep since at least version 3.8.
- Complete list of supported subcommands in the 'perf daemon' help
message.
- Update John Garry's email address for arm64 perf tooling on the

This was a mismerge of a semantic conflict in my merge of the driver
core updates, where commit ff62b8e6588f ("driver core: make struct
class.devnode() take a const *") changed the devnode function pointer
type. In the meantime, the drm tree I merged earlier had introduced a
new use of that in commit 8bf4889762a8 ("drivers/accel: define kconfig
and register a new major").
And of course this happens when I'm traveling with my laptop, and thus
didn't do a full allmodconfig build between every pull and before
pushing my work out.
So I only noticed later as I was doing my full build.

domain is present
On architectures such as s390 that do not use irq domains for MSI,
returning 0 as the maximum MSI index is a bit counter-productive,
as it indicates that no MSI can be allocated. Bad idea.
Instead, return the maximum we're willing to support in the MSI
backing store (MSI_XA_DOMAIN_SIZE), and let the arch code do its
usual thing.
Thanks to Matthew Rosato for fixing the fix.

For architectures such as s390 and powerpc that do not use
irq domains for MSIs, dev->msi.domain is always NULL, so
the per-device, per-bus MSI domain is also guaranteed to
be NULL.
So checking one without checking the other is bound to result
in a splat, followed by a memory leak as we don't free the MSI
descriptors.
Add the missing check.

It's caused by the assert_spin_locked() failing in assert_pte_locked().
The assert fails because the PTE was unlocked in text_area_cpu_up_mm(),
and never relocked.
The PTE page shouldn't be freed, the patching_mm is only used for
patching on this CPU, only that single PTE is ever mapped, and it's only
unmapped at CPU offline.
In fact assert_pte_locked() has a special case to ignore init_mm
entirely, and the patching_mm is more-or-less like init_mm, so possibly
the check could be skipped for patching_mm too.
But for now be conservative, and use the proper PTE accessors at
patching time, so that the PTE lock is held while the PTE is used. That
also avoids the warning in assert_pte_locked().
With that it's no longer necessary to save the PTE in
cpu_patching_context for the mm_patch_enabled() case.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core updates from Greg KH:
"Here is the set of driver core and kernfs changes for 6.2-rc1.
The "big" change in here is the addition of a new macro,
container_of_const() that will preserve the "const-ness" of a pointer
passed into it.
The "problem" of the current container_of() macro is that if you pass
in a "const *", out of it can comes a non-const pointer unless you
specifically ask for it. For many usages, we want to preserve the
"const" attribute by using the same call. For a specific example, this
series changes the kobj_to_dev() macro to use it, allowing it to be
used no matter what the const value is. This prevents every subsystem
from having to declare 2 different individual macros (i.e.
kobj_const_to_dev() and kobj_to_dev()) and having the compiler enforce
the const value at build time, which having 2 macros would not do
either.
The driver for all of this have been discussions with the Rust kernel
developers as to how to properly mark driver core, and kobject,
objects as being "non-mutable". The changes to the kobject and driver
core in this pull request are the result of that, as there are lots of
paths where kobjects and device pointers are not modified at all, so
marking them as "const" allows the compiler to enforce this.
So, a nice side affect of the Rust development effort has been already
to clean up the driver core code to be more obvious about object
rules.
All of this has been bike-shedded in quite a lot of detail on lkml
with different names and implementations resulting in the tiny version
we have in here, much better than my original proposal. Lots of
subsystem maintainers have acked the changes as well.
Other than this change, included in here are smaller stuff like:
- kernfs fixes and updates to handle lock contention better
- vmlinux.lds.h fixes and updates
- sysfs and debugfs documentation updates
- device property updates
All of these have been in the linux-next tree for quite a while with
no problems"

The actual clock feeding into the Mali GPU on the MT8183 is from the
clock gate in the MFGCFG block, not CLK_TOP_MFGPLL_CK from the TOPCKGEN
block, which itself is simply a pass-through placeholder for the MFGPLL
in the APMIXEDSYS block.
Fix the hardware description with the correct clock reference.

The size of device tree node secmon (bl31_secmon_reserved) was
incorrect. It should be increased to 2MiB (0x200000).
The origin setting will cause some abnormal behavior due to
trusted-firmware-a and related firmware didn't load correctly.
The incorrect behavior may vary because of different software stacks.
For example, it will cause build error in some Yocto project because
it will check if there was enough memory to load trusted-firmware-a
to the reserved memory.
When mt8195-demo.dts sent to the upstream, at that time the size of
BL31 was small. Because supported functions and modules in BL31 are
basic sets when the board was under early development stage.
Now BL31 includes more firmwares of coprocessors and maturer functions
so the size has grown bigger in real applications. According to the value
reported by customers, we think reserved 2MiB for BL31 might be enough
for maybe the following 2 or 3 years.
