Subject: [PATCH v1 0/5] Implement livepatch on PPC32

This series implements livepatch on PPC32.

This is largely copied from what's done on PPC64.

Christophe Leroy (5):
  livepatch: Fix build failure on 32 bits processors
  powerpc/ftrace: No need to read LR from stack in _mcount()
  powerpc/ftrace: Add module_trampoline_target() for PPC32
  powerpc/ftrace: Activate HAVE_DYNAMIC_FTRACE_WITH_REGS on PPC32
  powerpc/ftrace: Add support for livepatch to PPC32
