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

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

 * Initialize 'page_size' variable in the python binding, this was sent
   for perf/urgent by mistake, then when merging Ingo removed it, fixing
   the problem for perf/urgent, but when perf/urgent was merged with
   perf/core, where that initialization is needed, made the python
   binding mmap call to fail, fix it by initializing page_size again.

 * Add a browser for 'perf script' and make it available from the report
   and annotate browsers. It does filtering to find the scripts that
   handle events found in the perf.data file used. From Feng Tang

 * Move some functions from symbol.c to more appropriate files, creating
   dso.[ch] in the process, no code changes. From Jiri Olsa

 * Fix mmap error output message for when perf_mmap fails and returns
   !-EPERM, where the default for mmap_pages, INT_MAX, was causing a
   !power of 2 error message, fix from Jiri Olsa.
