Subject: [PATCH 1/1] tools kvm headers arm64: Update KVM headers from the kernel sources
Date: Sat, 12 Mar 2022 10:32:48 -0300	[thread overview]
Message-ID: <YiyhAK6sVPc83FaI@kernel.org> (raw)


FYI, I'm carrying this on my perf tools tree,

Regards,

- Arnaldo

----

To pick the changes from:

  a5905d6af492ee6a ("KVM: arm64: Allow SMCCC_ARCH_WORKAROUND_3 to be discovered and migrated")

That don't causes any changes in tooling (when built on x86), only
addresses this perf build warning:

  Warning: Kernel ABI header at 'tools/arch/arm64/include/uapi/asm/kvm.h' differs from latest version at 'arch/arm64/include/uapi/asm/kvm.h'
  diff -u tools/arch/arm64/include/uapi/asm/kvm.h arch/arm64/include/uapi/asm/kvm.h
