   as with older kernels where those tracepoints are present.

 - Also make it handle the new "node" kmem:kmalloc and
   kmem:kmem_cache_alloc tracepoint field introduced in that same
   commit.

 - Fix hardware tracing PMU address filter duplicate symbol selection,
   that was preventing to match with static functions with the same name
   present in different object files.

 - Fix regression on what linux/types.h file gets used to build the "BPF
   prologue" 'perf test' entry, the system one lacks the fmode_t
   definition used in this test, so provide that type in the test
   itself.

 - Avoid build breakage with libbpf < 0.8.0 + LIBBPF_DYNAMIC=1. If the
   user asks for linking with the libbpf package provided by the distro,
   then it has to be >= 0.8.0. Using the libbpf supplied with the kernel
   would be a fallback in that case.

 - Fix the build when libbpf isn't available or explicitly disabled via
   NO_LIBBPF=1.

 - Don't try to install libtraceevent plugins as its not anymore in the
   kernel sources and will thus always fail.

The newly added spi-cs-setup-ns doesn't really fit with the existing
property names for delays, rename it so that it does before it makes it
into a release and becomes ABI.

The two debug messages in spidev_open() dereference spidev->spi without
taking the lock and without checking if it's not null. This can lead to
a crash. Drop the messages as they're not needed - the user-space will
get informed about ENOMEM with the syscall return value.

There's a spinlock in place that is taken in file_operations callbacks
whenever we check if spidev->spi is still alive (not null). It's also
taken when spidev->spi is set to NULL in remove().

This however doesn't protect the code against driver unbind event while
one of the syscalls is still in progress. To that end we need a lock taken
continuously as long as we may still access spidev->spi. As both the file
ops and the remove callback are never called from interrupt context, we
can replace the spinlock with a mutex.

In 746bd29e ("perf build: Use tools/lib headers from install
path") we stopped having the tools/lib/ directory from the kernel
sources in the header include path unconditionally, which breaks the
build on systems with older versions of libbpf-devel, in this case 0.7.0
as some of the structures and function declarations present in the newer
version of libbpf included in the kernel sources (tools/lib/bpf) are not
anymore used, just the ones in the system libbpf.

So instead of trying to provide alternative functions when the
libbpf-bpf_program__set_insns feature test fails, fail a
LIBBPF_DYNAMIC=1 build (requesting the use of the system's libbpf) and
emit this build error message:

  $ make LIBBPF_DYNAMIC=1 -C tools/perf
  Makefile.config:593: *** Error: libbpf devel library needs to be >= 0.8.0 to build with LIBBPF_DYNAMIC, update or build statically with the version that comes with the kernel sources.  Stop.
  $

For v6.3 these tests will be revamped and we'll require libbpf 1.0 as a
minimal version for using LIBBPF_DYNAMIC=1, most distros should have it
by now or at v6.3 time.

The $(LIBBPF) target should only be a dependency of prepare if the
static version of libbpf is needed. Add a new LIBBPF_STATIC variable
that is set by Makefile.config. Use LIBBPF_STATIC to determine whether
the CFLAGS, etc. need updating and for adding $(LIBBPF) as a prepare
dependency.

As Makefile.config isn't loaded for "clean" as a target, always set
LIBBPF_OUTPUT regardless of whether it is needed for $(LIBBPF). This
is done to minimize conditional logic for $(LIBBPF)-clean.

perf kmem: Support field "node" in evsel__process_alloc_event() coping with recent tracepoint restructuring

Commit 11e9734b ("mm/slab_common: unify NUMA and UMA version of
tracepoints") adds the field "node" into the tracepoints 'kmalloc' and
'kmem_cache_alloc', so this patch modifies the event process function to
support the field "node".

If field "node" is detected by checking function evsel__field(), it
stats the cross allocation.

When the "node" value is NUMA_NO_NODE (-1), it means the memory can be
allocated from any memory node, in this case, we don't account it as a
cross allocation.

We had already disabled this warning for gcc-12 due to bugs in the value
range analysis, but it turns out we end up having some similar problems
with gcc-11.3 too, so let's disable it there too.

Older gcc versions end up being increasingly less relevant, and
hopefully clang and newer version of gcc (ie gcc-13) end up working
reliably enough that we still get the build coverage even when we
disable this for some versions.

While running 'perf test' for bpf, observed that "BPF prologue

powerpc:

  2 errors generated.

The test code tests/bpf-script-test-prologue.c uses fmode_t.  And the
error above is for "fmode_t" which is defined in include/linux/types.h
as part of kernel build directory: "/lib/modules/<kernel_version>/build"
that comes from kernel devel [ soft link to /usr/src/<kernel_version> ].

Clang picks this header file from "-working-directory" build option that
specifies this build folder.

But the commit 14e4b9f4 ("perf trace: Raw augmented syscalls fix
libbpf 1.0+ compatibility") changed the include directory to use:
"/usr/include".

Post this change, types.h from /usr/include/ is getting picked upwhich
doesn’t contain definition of "fmode_t" and hence fails to compile.

Compilation command before this commit:

  /usr/bin/clang -D__KERNEL__ -D__NR_CPUS__=72 -DLINUX_VERSION_CODE=0x50e00 -xc  -I/root/lib/perf/include/bpf -nostdinc -I./arch/powerpc/include -I./arch/powerpc/include/generated  -I./include -I./arch/powerpc/include/uapi -I./arch/powerpc/include/generated/uapi -I./include/uapi -I./include/generated/uapi -include ./include/linux/compiler-version.h -include ./include/linux/kconfig.h  -Wno-unused-value -Wno-pointer-sign -working-directory /lib/modules/<ver>/build -c - -target bpf  -g -O2 -o -

Compilation command after this commit:

  /usr/bin/clang -D__KERNEL__ -D__NR_CPUS__=72 -DLINUX_VERSION_CODE=0x50e00 -xc  -I/usr/include/ -nostdinc -I./arch/powerpc/include -I./arch/powerpc/include/generated  -I./include -I./arch/powerpc/include/uapi -I./arch/powerpc/include/generated/uapi -I./include/uapi -I./include/generated/uapi -include ./include/linux/compiler-version.h -include ./include/linux/kconfig.h  -Wno-unused-value -Wno-pointer-sign -working-directory /lib/modules/<ver>/build -c - -target bpf  -g -O2 -o -

The difference is addition of -I/usr/include/  in the first line which
is causing the error. Fix this by adding typedef for "fmode_t" in the
testcase to solve the compile issue.

TPM 1 is sometimes broken across system suspends, due to races or
locking issues or something else that haven't been diagnosed or fixed
yet, most likely having to do with concurrent reads from the TPM's
hardware random number generator driver. These issues prevent the system
from actually suspending, with errors like:

  tpm tpm0: A TPM error (28) occurred continue selftest
  ...
  tpm tpm0: A TPM error (28) occurred attempting get random
  ...
  tpm tpm0: Error (28) sending savestate before suspend
  tpm_tis 00:08: PM: __pnp_bus_suspend(): tpm_pm_suspend+0x0/0x80 returns 28
  tpm_tis 00:08: PM: dpm_run_callback(): pnp_bus_suspend+0x0/0x10 returns 28
  tpm_tis 00:08: PM: failed to suspend: error 28
  PM: Some devices failed to suspend, or early wake event detected

This issue was partially fixed by 23393c64

 ("char: tpm: Protect
tpm_pm_suspend with locks"), in a last minute 6.1 commit that Linus took
directly because the TPM maintainers weren't available. However, it
seems like this just addresses the most common cases of the bug, rather
than addressing it entirely. So there are more things to fix still,
apparently.

In lieu of actually fixing the underlying bug, just allow system suspend
to continue, so that laptops still go to sleep fine. Later, this can be
reverted when the real bug is fixed.

Commit 55d1cbbb

 ("hfs/hfsplus: use WARN_ON for sanity check") fixed
a build warning by turning a comment into a WARN_ON(), but it turns out
that syzbot then complains because it can trigger said warning with a
corrupted hfs image.

The warning actually does warn about a bad situation, but we are much
better off just handling it as the error it is.  So rather than warn
about us doing bad things, stop doing the bad things and return -EIO.

While at it, also fix a memory leak that was introduced by an earlier
fix for a similar syzbot warning situation, and add a check for one case
that historically wasn't handled at all (ie neither comment nor
subsequent WARN_ON).
