[RFC GIT PULL] perf updates

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


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.


Frederic Weisbecker (2):
x86: Fix rbp saving in pt_regs on irq entry
perf: Build tools with frame pointer
