Retain the PIP packet payload as is, instead of just the CR3, because it
contains also the VMX NR flag which is needed to track VM-Entry.

vmlaunch and vmresume as branch instructions.
Note, sample flags will show "VMentry" even if the VM-Entry fails.

This fix is for a failure that occurred in the DWARF unwind perf test.
Stack unwinders may probe memory when looking for frames.
Memory sanitizer will poison and track uninitialized memory on the
stack, and on the heap if the value is copied to the heap.
This can lead to false memory sanitizer failures for the use of an
uninitialized value.
Avoid this problem by removing the poison on the copied stack.
The full msan failure with track origins looks like:

x86 arch provides the testing for conversion between tsc and perf time,
the testing is located in x86 arch folder. Move this testing out from
x86 arch folder and place it into the common testing folder, so allows
to execute tsc testing on other architectures (e.g. Arm64).
This patch removes the inclusion of "arch-tests.h" from the testing
code, this can avoid building failure if any arch has no this header
file.
Committer testing:
$ perf test -v tsc
Couldn't bump rlimit(MEMLOCK), failures may take place when creating BPF maps, etc

And update linux/linkage.h, which requires in turn that we make these
files switch from ENTRY()/ENDPROC() to SYM_FUNC_START()/SYM_FUNC_END():

tools/perf/arch/arm/tests/regs_load.S
tools/perf/arch/powerpc/tests/regs_load.S

We also need to switch SYM_FUNC_START_LOCAL() to SYM_FUNC_START() for
the functions used directly by 'perf bench', and update
tools/perf/check_headers.sh to ignore those changes when checking if the
kernel original files drifted from the copies we carry.
This is to get the changes from:

And pick the shortest name: 'struct maps'.
The split existed because we used to have two groups of maps, one for
functions and one for variables, but that only complicated things,
sometimes we needed to figure out what was at some address and then had
to first try it on the functions group and if that failed, fall back to
the variables one.
That split is long gone, so for quite a while we had only one struct
maps per struct map_groups, simplify things by combining those structs.
First patch is the minimum needed to merge both, follow up patches will
rename 'thread->mg' to 'thread->maps', etc.

As this isn't used at all in mmap.h but in evlist.h, so to cut down the
header dependency tree, move it to where it is used.
Also add mmap.h to the places using it but previously getting it
indirectly via evlist.h.
Add missing pthread.h to evlist.h, as it has a pthread_t struct member
and was getting the header via mmap.h.
Noticed while processing a Jiri's libperf batch touching mmap.h, where
almost everything gets rebuilt because evlist.h is so popular, so cut
down't this rebuild the world party.

Now that there's a common version of the decoder for all tools, use it
instead of the local copy.
Also use perf's check-headers.sh script to diff the decoder files to
make sure they remain in sync with the kernel version. Objtool has a
similar check.
Committer notes:
Had to keep this all pointing explicitely to x86 headers/files, i.e.
instead of asm/isnn.h we had to use ../include/asm/insn.h when the files
were in differemt dirs, or just replace "<asm/foo.h>" with "foo.h".
This way we continue to be able to process perf.data files with Intel PT
traces in distros other than x86.
Also fixed up the awk script paths to use $(srcdir)/tools/arch instead
or relative directories so that we keep detached tarballs (make help |
grep perf) working.
For now the include lines in these headers are being ignored so as not
to flag false reports of kernel/tools out of sync.
