tools uapi x86: Sync vmx.h with the kernel To pick up the changes from: 2b27924bb1d4 ("KVM: nVMX: always use early vmcs check when EPT is disabled") That causes this object in the tools/perf build process to be rebuilt: CC /tmp/build/perf/arch/x86/util/kvm-stat.o But it isn't using VMX_ABORT_ prefixed constants, so no change in behaviour. This silences this perf build warning: Warning: Kernel ABI header at 'tools/arch/x86/include/uapi/asm/vmx.h' differs from latest version at 'arch/x86/include/uapi/asm/vmx.h' diff -u tools/arch/x86/include/uapi/asm/vmx.h arch/x86/include/uapi/asm/vmx.h Cc: Adrian Hunter <firstname.lastname@example.org> Cc: Jiri Olsa <email@example.com> Cc: Namhyung Kim <firstname.lastname@example.org> Cc: Paolo Bonzini <email@example.com> Link: https://firstname.lastname@example.org Signed-off-by: Arnaldo Carvalho de Melo <email@example.com>
