Arnaldo Carvalho de Melo d976a6e9d9 tools headers: Sync copy of kvm UAPI headers 
In 801e459a6f ("KVM: x86: Add a framework for supporting MSR-based
features") a new ioctl was introduced, which with this sync of the kvm
UAPI headers, makes 'perf trace' know about it:

  $ cd /tmp/build/perf/trace/beauty/generated/ioctl/
  $ diff -u kvm_ioctl_array.c.old kvm_ioctl_array.c
  --- /tmp/kvm_ioctl_array.c	2018-03-05 11:55:38.409145056 -0300
  +++ /tmp/build/perf/trace/beauty/generated/ioctl/kvm_ioctl_array.c	2018-03-05 11:56:17.456153501 -0300

 	[0x04] = "GET_VCPU_MMAP_SIZE",
 	[0x05] = "GET_SUPPORTED_CPUID",
 	[0x09] = "GET_EMULATED_CPUID",
  +	[0x0a] = "GET_MSR_FEATURE_INDEX_LIST",
 	[0x40] = "SET_MEMORY_REGION",
 	[0x41] = "CREATE_VCPU",
 	[0x42] = "GET_DIRTY_LOG",

So when using 'perf trace -e ioctl' that will appear along with the
others, like in this excerpt of a system wide session:

  14.556 ( 0.006 ms): CPU 0/KVM/16077 ioctl(fd: 19<anon_inode:kvm-vcpu:0>, cmd: KVM_RUN) = 0

This also silences the perf build header copy drift verifier:

  make: Entering directory '/home/acme/git/perf/tools/perf'
    BUILD:   Doing 'make -j4' parallel build
  Warning: Kernel ABI header at 'tools/include/uapi/linux/kvm.h' differs from latest version at 'include/uapi/linux/kvm.h'
