Pull perf tools fixes from Arnaldo Carvalho de Melo:

 - Fix alignment for cpu map masks in event encoding.

 - Support reading PERF_FORMAT_LOST, perf tool counterpart for a feature
   that was added in this merge window.

 - Sync perf tools copies of kernel headers: socket, msr-index, fscrypt,
   cpufeatures, i915_drm, kvm, vhost, perf_event.
