Pull perf tools fixes from Arnaldo Carvalho de Melo:

 - Prevent reading into undefined memory in the expression lexer,
   accounting for a trailer backslash followed by the null byte.

 - Fix file mode when copying files to the build id cache, the problem
   happens when the cache directory is in a different file system than
   the file being cached, otherwise the mode was preserved as only a
   hard link would be done to save space.

 - Fix a related build-id 'perf test' entry that checked that permission
   when caching PE (Portable Executable) files, used when profiling
   Windows executables under wine.

 - Sync the tools/ copies of kvm headers, build_bug.h, socket.h and
   arm64's cputype.h with the kernel sources.
