um/mm: support __HAVE_ARCH_PTE_SWP_EXCLUSIVE
Let's support __HAVE_ARCH_PTE_SWP_EXCLUSIVE by using bit 10, which is yet
unused for swap PTEs.
The pte_mkuptodate() is a bit weird in __pte_to_swp_entry() for a swap PTE
... but it only messes with bit 1 and 2 and there is a comment in
set_pte(), so leave these bits alone.
While at it, mask the type in __swp_entry().
