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. Signed-off-by: Steven Rostedt <srostedt@redhat.com>
