[PATCH 0/3] Convert x86/mm/pat to ptdescs

["Vishal Moola (Oracle)" <vishal.moola@gmail.com>]

x86/mm/pat should be using ptdescs. One line has already been
converted to pagetable_free(), while the allocation sites use
get_free_pages(). This causes issues separately allocating ptdescs
from struct page.

These patches convert the allocation/free sites to use ptdescs. In
the short term, this helps enable Matthew's work to allocate frozen
pagetables. And in the long term, this will help us cleanly split
ptdesc allocations from struct page.

------

Based on current mm-new.

Vishal Moola (Oracle) (3):
  x86/mm/pat: Convert pte code to use ptdescs
  x86/mm/pat: Convert pmd code to use ptdescs
  x86/mm/pat: Convert split_large_page() to use ptdescs
