Merge tag 'perf-core-for-mingo-4.21-20190103' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux

 into perf/urgent

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

perf c2c:

  Jiri Olsa:

  - Change the default coalesce setup to from '--coalesce pid,iaddr' to just '--coalesce iaddr'.

  - Increase the HITM ratio limit for displayed cachelines.

perf script:

  Andi Kleen:

  - Fix LBR skid dump problems in brstackinsn.

perf trace:

  Arnaldo Carvalho de Melo:

  - Check if the raw_syscalls:sys_{enter,exit} are setup before setting tp filter.

  - Do not hardcode the size of the tracepoint common_ fields.

  - Beautify USBDEFFS_ ioctl commands.

  Colin Ian King:

  - Use correct SECCOMP prefix spelling, "SECOMP_*" -> "SECCOMP_*".

perf python:

  Jiri Olsa:

  - Do not force closing original perf descriptor in evlist.get_pollfd().

tools misc:

  Jiri Olsa:

  - Allow overriding CFLAGS and LDFLAGS.

perf build:

  Stanislav Fomichev:

  - Don't unconditionally link the libbfd feature test to -liberty and -lz

thread-stack:

  Adrian Hunter:

  - Fix processing for the idle task, having a stack per cpu.
