v5 cover letter: https://lore.kernel.org/kernel-hardening/20191030073111.140493-1-ruscur@russell.cc/
v4 cover letter: https://lists.ozlabs.org/pipermail/linuxppc-dev/2019-October/198268.html
v3 cover letter: https://lists.ozlabs.org/pipermail/linuxppc-dev/2019-October/198023.html

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
forward.

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: Set ARCH_HAS_STRICT_MODULE_RWX
  powerpc/configs: Enable STRICT_MODULE_RWX in skiroot_defconfig
