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

I think we know patch 5 will need a respin because of the STRICT RWX vs
livepatching issue (https://github.com/linuxppc/issues/issues/375).

So should I take patches 2,3,4 for now?

Yes you can take them now I think.

Thanks
Christophe
