Make secretmem set AS_NO_DIRECT_MAP on its struct address_space, to drop
all the vma_is_secretmem()/secretmem_mapping() checks that are based on
checking explicitly for the secretmem ops structures.
This drops a optimization in gup_fast_folio_allowed() where
secretmem_mapping() was only called if CONFIG_SECRETMEM=y. secretmem is
enabled by default since commit b758fe6df50d ("mm/secretmem: make it on
by default"), so the secretmem check did not actually end up elided in
most cases anymore anyway.

Ah, there it is. Can both patches somehow be squashed?
