Pull perf tools fixes from Arnaldo Carvalho de Melo:

 - Fix the 'local_weight', 'weight' (memory access latency),
   'local_ins_lat', 'ins_lat' (instruction latency) and 'pstage_cyc'
   (pipeline stage cycles) sort key sample aggregation.

 - Fix 'perf test' entry for watchpoints on s/390.

 - Fix branch_stack entry endianness check in the 'perf test' sample
   parsing test.

 - Fix ARM SPE handling on 'perf inject'.

 - Fix memory leaks detected with ASan.

 - Fix build on arm64 related to reallocarray() availability.

 - Sync copies of kernel headers: cpufeatures, kvm, MIPS syscalltable
   (futex_waitv).
