perf/urgent fixes:

. Revert "perf pmu: Fix pmu events parsing rule", as it broke Intel PT
   event description parsing (Arnaldo Carvalho de Melo)
 
 . Sync x86's cpufeatures.h and kvm UAPI headers with the kernel sources,
   suppressing the ABI drift warnings (Arnaldo Carvalho de Melo)
 
 - Remove duplicated entry for westmereep-dp in Intel's mapfile.csv (William Cohen)
 
 - Fix typo in 'perf bench numa' options description (Yisheng Xie)
