perf updates

Ingo,

Please pull the perf/core branch that can be found at:

git://git.kernel.org/pub/scm/linux/kernel/git/frederic/random-tracing.git
perf/core

The changelog of the rbp/pt_regs patch has been refined and the CFI annotations reported by Jan (and another I found lately) have been fixed, hopefully.

Thanks,
Frederic

In dump_stack function, bp isn't used anymore, which is introduced by commit 9c0729dc8062bed96189bd14ac6d4920f3958743. This patch removes bp completely.
