David Hildenbrand bff9beaa2e powerpc/pgtable: support __HAVE_ARCH_PTE_SWP_EXCLUSIVE for book3s 
Right now, the last 5 bits (0x1f) of the swap entry are used for the type
and the bit before that (0x20) is used for _PAGE_SWP_SOFT_DIRTY.  We
cannot use 0x40, as that collides with _RPAGE_RSV1 -- contained in
_PAGE_HPTEFLAGS.  The next candidate would be _RPAGE_SW3 (0x200) -- which
is used for _PAGE_SOFT_DIRTY for !swp ptes.

So let's just use _PAGE_SOFT_DIRTY for _PAGE_SWP_SOFT_DIRTY (to make it
easier to grasp) and use 0x20 now for _PAGE_SWP_EXCLUSIVE.
