[PATCH v6 0/7] set_memory() routines and STRICT_MODULE_RWX

[Russell Currey <ruscur@russell.cc>]

Back again, just minor changes.

v5: https://patchwork.ozlabs.org/project/linuxppc-dev/list/?series=160869

Changes since v5:
	[1/8]: Patch 8/8 squashed as suggested by Andrew Donnellan
	       Added a note to the comment of change_page_attr()
	       Rename size to sz to meet 90 chars without multiple lines

	[8/8]: Removed, change_memory_attr() section squashed, rest dropped
	       as suggested by Christophe Leroy (since I just assumed it was
	       the right thing to do instead of actually checking)

Thanks for the feedback.
