[PATCH 0/6] x86/dumpstack: replace dump_trace() with a new unwinder

[Josh Poimboeuf]

The last version was posted as part of a much larger patch set:

  https://lkml.kernel.org/r/cover.1471525031.git.jpoimboe@xxxxxxxxxx

People complained about the set being too big, so it was split up into
more digestible pieces.  All the prerequisite patches for the unwinder
have now been merged.

See patch 1/6 for the background and justification for this change.

Josh Poimboeuf (6):
  x86/unwind: add new unwind interface and implementations
  perf/x86: convert perf_callchain_kernel() to use the new unwinder
  x86/stacktrace: convert save_stack_trace_*() to use the new unwinder
  oprofile/x86: convert x86_backtrace() to use the new unwinder
  x86/dumpstack: convert show_trace_log_lvl() to use the new unwinder
  x86/dumpstack: remove dump_trace() and related callbacks
