Matthew Wilcox (Oracle) e183cf9322 mm/page_owner: change split_page_owner to take a count 
[ Upstream commit 8fb156c9ee2db94f7127c930c89917634a1a9f56 ]

The implementation of split_page_owner() prefers a count rather than the
old order of the page.  When we support a variable size THP, we won't
have the order at this point, but we will have the number of pages.
So change the interface to what the caller and callee would prefer.
