To pick the changes from:

  3d8f61bf ("x86: KVM: Add common feature flag for AMD's PSFD")
  3763bf58 ("x86/cpufeatures: Redefine synthetic virtual NMI bit as AMD's "real" vNMI")
  6449dcb0 ("x86: CPUID and CR3/CR4 flags for Linear Address Masking")
  be8de49b ("x86/speculation: Identify processors vulnerable to SMT RSB predictions")
  e7862eda ("x86/cpu: Support AMD Automatic IBRS")
  faabfcb1 ("x86/cpu, kvm: Add the SMM_CTL MSR not present feature")
  5b909d4a ("x86/cpu, kvm: Add the Null Selector Clears Base feature")
  84168ae7 ("x86/cpu, kvm: Move X86_FEATURE_LFENCE_RDTSC to its native leaf")
  a9dc9ec5 ("x86/cpu, kvm: Add the NO_NESTED_DATA_BP feature")
  f8df91e7 ("x86/cpufeatures: Add macros for Intel's new fast rep string features")
  78335aac ("x86/cpufeatures: Add Bandwidth Monitoring Event Configuration feature flag")
  f334f723 ("x86/cpufeatures: Add Slow Memory Bandwidth Allocation feature flag")
  a018d2e3 ("x86/cpufeatures: Add Architectural PerfMon Extension bit")

This causes these perf files to be rebuilt and brings some X86_FEATURE
that will be used when updating the copies of
tools/arch/x86/lib/mem{cpy,set}_64.S with the kernel sources:

  CC       /tmp/build/perf/bench/mem-memcpy-x86-64-asm.o
  CC       /tmp/build/perf/bench/mem-memset-x86-64-asm.o

And addresses this perf build warning:

  Warning: Kernel ABI header at 'tools/arch/x86/include/asm/cpufeatures.h' differs from latest version at 'arch/x86/include/asm/cpufeatures.h'
  diff -u tools/arch/x86/include/asm/cpufeatures.h arch/x86/include/asm/cpufeatures.h
