[PATCH 0/4] x86/unwind: add some unwinder warnings

[Josh Poimboeuf <jpoimboe@redhat.com>]

Detect some stack error conditions in the unwinder and warn about them.

These warnings may help with debugging stack corruption issues.

Josh Poimboeuf (4):
  x86/unwind: warn on bad frame pointer
  x86/unwind: ensure stack grows down
  x86/dumpstack: warn on stack recursion
  x86/unwind: detect bad stack return address
