Merge tag 'trace-3.12' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
Pull tracing updates from Steven Rostedt:
"Not much changes for the 3.12 merge window. The major tracing changes
are still in flux, and will have to wait for 3.13.
The changes for 3.12 are mostly clean ups and minor fixes.
H Peter Anvin added a check to x86_32 static function tracing that
helps a small segment of the kernel community.
Oleg Nesterov had a few changes from 3.11, but were mostly clean ups
and not worth pushing in the -rc time frame.
Li Zefan had small clean up with annotating a raw_init with __init.
I fixed a slight race in updating function callbacks, but the race is
so small and the bug that happens when it occurs is so minor it's not
even worth pushing to stable.
The only real enhancement is from Alexander Z Lam that made the
tracing_cpumask work for trace buffer instances, instead of them all
sharing a global cpumask"
