Subject: [PATCH FYI] tools kvm headers arm64: Update KVM headers from the kernel sources
Date: Wed, 30 Mar 2022 13:14:25 -0300 [thread overview]
Message-ID: <YkSB4Q7kWmnaqeZU@kernel.org> (raw)
Just FYI, I'm carrying this on the perf tools tree.

To pick the changes from:
34739fd95fab3a5e ("KVM: arm64: Indicate SYSTEM_RESET2 in kvm_run::system_event flags field")
583cda1b0e7d5d49 ("KVM: arm64: Refuse to run VCPU if the PMU doesn't match the physical CPU")
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'
