Kirill A. Shutemov ba98828088 thp: add option to setup migration entries during PMD split 
We are going to use migration PTE entries to stabilize page counts.  If
the page is mapped with PMDs we need to split the PMD and setup
migration entries.  It's reasonable to combine these operations to avoid
double-scanning over the page table.
