[RFC GIT PULL] perf updates

[Frederic Weisbecker]

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
	
Soeren reported some time ago that callchains were broken on
x86_64 with cpu-clock/task-clock events. After some time I
finally found the problem was in the irq low level arg saving.
It touches fragile code though, I hope some people can
have a look over the fix.

Thanks,
	Frederic
