[PATCH 0/7] perf updates and fixes

[Frederic Weisbecker <fweisbec@gmail.com>]

Hi,

The series is not yet mergeable because it would break PowerPc
(hot regs snapshot API has been changed, and I don't know how
to update PowerPc for that).

But if you're fine with the ideas, I can integrate the necessary
changes to fix this, and also separate fixes and updates.

Thanks.

Frederic Weisbecker (7):
  perf: Drop the frame reliablity check
  perf: Fetch hot regs from the template caller
  x86: Unify dumpstack.h and stacktrace.h
  perf: Move perf_arch_fetch_caller_regs into a macro
  perf: Make perf_fetch_caller_regs rewind to the first caller only
  perf: Use hot regs with software sched/migrate events
  perf: Correctly align perf event tracing buffer
