powerpc/ppc64: ftrace, handle module trampolines for dyn ftrace
Impact: Allow 64 bit PowerPC to trace modules with dynamic ftrace
This adds code to handle the PPC64 module trampolines, and allows for
PPC64 to use dynamic ftrace.
Thanks to Paul Mackerras for these updates:
- fix the mod and rec->arch.mod NULL checks.
- fix to is_bl_op compare.
Thanks to Milton Miller for:
- finding the nasty race with using two nops, and recommending
instead that I use a branch 8 forward.
