Subject: [PATCH 04/11] tools headers: Sync x86 kvm and cpufeature headers with the kernel
Date: Mon,  2 Dec 2024 19:53:42 -0800	[thread overview]
Message-ID: <20241203035349.1901262-5-namhyung@kernel.org> (raw)
In-Reply-To: <20241203035349.1901262-1-namhyung@kernel.org>

To pick up the changes in this cset:

  a0423af92cb31e6f ("x86: KVM: Advertise CPUIDs for new instructions in Clearwater Forest")
  0c487010cb4f79e4 ("x86/cpufeatures: Add X86_FEATURE_AMD_WORKLOAD_CLASS feature bit")
  1ad4667066714369 ("x86/cpufeatures: Add X86_FEATURE_AMD_HETEROGENEOUS_CORES")
  104edc6efca62838 ("x86/cpufeatures: Rename X86_FEATURE_FAST_CPPC to have AMD prefix")
  3ea87dfa31a7b0bb ("x86/cpufeatures: Add a IBPB_NO_RET BUG flag")
  ff898623af2ed564 ("x86/cpufeatures: Define X86_FEATURE_AMD_IBPB_RET")
  dcb988cdac85bad1 ("KVM: x86: Quirk initialization of feature MSRs to KVM's max configuration")

This addresses these perf build warnings:

  Warning: Kernel ABI header differences:
    diff -u tools/arch/x86/include/asm/cpufeatures.h arch/x86/include/asm/cpufeatures.h
    diff -u tools/arch/x86/include/uapi/asm/kvm.h arch/x86/include/uapi/asm/kvm.h

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