[PATCH v2 0/2] mm: PAGE_KERNEL_* fallbacks

["Luis R. Rodriguez" <mcgrof@kernel.org>]

While dusting out the firmware loader closet I spotted a PAGE_KERNEL_*
fallback hack. This hurts my eyes, and it should also be blinding
others. Turns out we have other PAGE_KERNEL_* fallback hacks in
other places.

This moves them to asm-generic, and keeps track of architectures which
need some love or review. At least 0-day was happy with the changes.

Matthew Wilcox did put together a PAGE_KERNEL_RO patch for ia64, that
needs review and testing, and if it goes well it should be merged.

Luis R. Rodriguez (2):
  mm: provide a fallback for PAGE_KERNEL_RO for architectures
  mm: provide a fallback for PAGE_KERNEL_EXEC for architectures
