Merge tag 'perf-core-for-mingo' of git://git./linux/kernel/git/acme/linux into perf/core

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

 * 'perf trace' arg formatting improvements to allow masking arguments
   in syscalls such as futex and open, where the some arguments are
   ignored and thus should not be printed depending on other args.

 * Beautify futex open, openat, open_by_handle_at, lseek and futex syscalls.

 * Add dummy software event to use when wanting just to keep receiving
   PERF_RECORD_{MMAP,COMM,etc}, add test for it, from Adrian Hunter.

 * Fix symbol offset computation for some dsos in 'perf script', from David Ahern.

 * Skip unsupported hardware events in 'perf list', from Namhyung Kim.
