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

Annotation fixes/improvements from Arnaldo Carvalho de Melo:

. Make the annotatation toggles (hide_src_code, jump_arrows, use_offset, etc)
  global so that navigation doesn't resets them on new annotations.

. Introduce an '[annotate]' config file section to allow permanent changes
  to the annotate browser defaults.
