Merge tag 'perf-core-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git...

Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:

 * Tidy up sample parsing validation, from Adrian Hunter.

 * Make events stream always parsable by adding a new sample_type bit:
   PERF_SAMPLE_IDENTIFIER, that when requested will be always aat a fixed
   position in all PERF_RECORD_ records, from Adrian Hunter.

 * Add a sample parsing test, from Adrian Hunter.

 * Add option to 'perf trace' to analyze events in a file versus live,
   so that one can do:

   [root@zoo ~]# perf record -a -e raw_syscalls:* sleep 1
   [ perf record: Woken up 0 times to write data ]
   [ perf record: Captured and wrote 25.150 MB perf.data (~1098836 samples) ]
   [root@zoo ~]# perf trace -i perf.data -e futex --duration 1
      17.799 ( 1.020 ms): 7127 futex(uaddr: 0x7fff3f6c6674, op: 393, val: 1, utime: 0x7fff3f6c6470, ua
     113.344 (95.429 ms): 7127 futex(uaddr: 0x7fff3f6c6674, op: 393, val: 1, utime: 0x7fff3f6c6470, uaddr2: 0x7fff3f6c6648, val3: 4294967
     133.778 ( 1.042 ms): 18004 futex(uaddr: 0x7fff3f6c6674, op: 393, val: 1, utime: 0x7fff3f6c6470, uaddr2: 0x7fff3f6c6648, val3: 429496
   [root@zoo ~]#

   From David Ahern.

 * Honor target pid / tid options in 'perf trace' when analyzing a file,
   from David Ahern.

 * Handle missing HUGEPAGE defines in the mmap beautifier in 'perf trace',
   from David Ahern.
