[PATCH 00/11] perf tools: Sync kernel and tools headers for v6.17

[PATCH 00/11] perf tools: Sync kernel and tools headers for v6.17

[Namhyung Kim]

Hello,

I'll carry these changes on the perf-tools tree to update perf tools to
understand new syscalls and parameters.  You can refer to README file in
the tools/include/uapi directory why it's needed.

Thanks,
Namhyung

[PATCH 05/11] tools headers: Sync arm64 headers with the kernel source

[Namhyung Kim]

To pick up the changes in this cset:

  efe676a1a7554219 arm64: proton-pack: Add new CPUs 'k' values for branch mitigation
  e18c09b204e81702 arm64: Add support for HIP09 Spectre-BHB mitigation
  a9b5bd81b294d30a arm64: cputype: Add MIDR_CORTEX_A76AE
  53a52a0ec7680287 arm64: cputype: Add comments about Qualcomm Kryo 5XX and 6XX cores
  401c3333bb2396aa arm64: cputype: Add QCOM_CPU_PART_KRYO_3XX_GOLD
  86edf6bdcf0571c0 smccc/kvm_guest: Enable errata based on implementation CPUs
  0bc9a9e85fcf4ffb KVM: arm64: Work around x1e's CNTVOFF_EL2 bogosity

This addresses these perf build warnings:

  Warning: Kernel ABI header differences:
    diff -u tools/arch/arm64/include/asm/cputype.h arch/arm64/include/asm/cputype.h

But the following two changes cannot be applied since they introduced
new build errors in util/arm-spe.c.  So it still has the warning after
this change.

  c8c2647e69bedf80 arm64: Make  _midr_in_range_list() an exported function
  e3121298c7fcaf48 arm64: Modify _midr_range() functions to read MIDR/REVIDR internally

Please see tools/include/uapi/README for further details.

Hi Namhyung,

Thanks for working on this. It is on our todo list for automatic
generating MIDR. Sorry for any troubling during the syncing.

Just a minor comment below.

Currently, no one uses this API. It seems to me that we don't need to
sync this code chunk.

Otherwise, other changes LGTM.

No worries, and thanks for your review.  I'm glad you noticed the issue
and have it in you TODO list. :)

Ok, but it'd be easier for me just to have the change anyway.
