[PATCH 0/3] powerpc/module_64: Fix _mcount() stub

[Naveen N. Rao]

This series addresses the crash reported by Qian Cai on ppc64le with 
-mprofile-kernel here:
https://lore.kernel.org/r/15AC5B0E-A221-4B8C-9039-FA96B8EF7C88@lca.pw

While fixing patch_instruction() should address the crash, we should 
still change the default stub we setup for _mcount() for cases where a 
kernel is built without ftrace.

- Naveen


Naveen N. Rao (3):
  powerpc/module_64: Consolidate ftrace code
  powerpc/module_64: Simplify check for -mprofile-kernel ftrace
    relocations
  powerpc/module_64: Use special stub for _mcount() with
    -mprofile-kernel
