Jérôme Glisse 8c3328f1f3 mm/migrate: migrate_vma() unmap page from vma while collecting pages 
Common case for migration of virtual address range is page are map only
once inside the vma in which migration is taking place.  Because we
already walk the CPU page table for that range we can directly do the
unmap there and setup special migration swap entry.
