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