To pick up changes from:

  b0a3f0e894f34e01 ("arm64/sysreg: Replace TCR_EL1 field macros")
  3bbf004c4808e2c3 ("arm64: cputype: Add Neoverse-V3AE definitions")
  e185c8a0d84236d1 ("arm64: cputype: Add NVIDIA Olympus definitions")
  52b49bd6de29a89a ("arm64: cputype: Remove duplicate Cortex-X1C definitions")

This should address these tools/perf build warnings:

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

Please see tools/include/README.kernel-copies.

Note that this is still out of sync due to is_midr_in_range_list().

Just remind, this is duplicated with patch [1], so you may decide
which one to pick for merging.

Otherwise, LGTM:

Oh, thanks for the reminder.  I've missed it.  I think it's small enough
to merge to perf-tools tree.  I'll drop this part.
