[2/5]: Use patch_instruction() instead of memcpy() thanks to mpe Thanks for the feedback, hopefully this is the final iteration. I have a patch to remove the STRICT_KERNEL_RWX incompatibility with RELOCATABLE for book3s64 coming soon, so with that we should have a great basis for powerpc RWX going forward.
