Suren Baghdasaryan 51eab7ecc4 BACKPORT: selftests/mm: add separate UFFDIO_MOVE test for PMD splitting
Add a test for UFFDIO_MOVE ioctl operating on a hugepage which has to be
split because destination is marked with MADV_NOHUGEPAGE.  With this we
cover all 3 cases: normal page move, hugepage move, hugepage splitting
before move.
