Merge tag 'perf-core-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core
Pull perf/tools improvements and fixes from Arnaldo Carvalho de Melo:
* Honour -m option in 'trace', the tool was offering the option to
set the mmap size, but wasn't using it when doing the actual mmap
on the events file descriptors, fix from Jiri Olsa.
* Correct the message in feature-libnuma checking, swowing the right
devel package names for various distros, from Dongsheng Yang.
* Polish 'readn' function and introduce its counterpart, 'writen', from
Jiri Olsa.
* Start moving timechart state from global variables to a 'perf_tool' derived
'timechart' struct.
