Subject: [PATCH v6 0/5] Implement STRICT_MODULE_RWX for powerpc

v5 cover letter:
v4 cover letter:
v3 cover letter:

Changes since v5:
	[1/5]: Addressed review comments from Christophe Leroy (thanks!)
	[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

Russell Currey (5):
  powerpc/mm: Implement set_memory() routines
  powerpc/kprobes: Mark newly allocated probes as RO
  powerpc/mm/ptdump: debugfs handler for W+X checks at runtime
  powerpc/configs: Enable STRICT_MODULE_RWX in skiroot_defconfig
