[GIT PULL] x86/mm for 7.4-rc1

[Dave Hansen]

Hi Linus,

Please pull some x86/mm changes for 7.4-rc1. The __add_pages() and
pgd_clear() ones are pretty mundane.

But the W^X ones are worth calling out. Effectively, the checks that
were supposed to be looking out for Write+Exec permission mappings
were busted. This fixes them, so we should all be on the lookout for
new warnings, both false positives and real ones.
