      tools arch kvm: Sync kvm headers with the kernel sources · c499d1f4
      Arnaldo Carvalho de Melo authored
      To pick up the changes from:
      
        41040cf7 ("arm64/sve: Fix missing SVE/FPSIMD endianness conversions")
        6ca00dfa ("KVM: x86: Modify struct kvm_nested_state to have explicit fields for data")
      
      None entail changes in tooling.
      
      This silences these tools/perf build warnings:
      
        Warning: Kernel ABI header at 'tools/arch/x86/include/uapi/asm/kvm.h' differs from latest version at 'arch/x86/include/uapi/asm/kvm.h'
