Matthew Wilcox (Oracle) d973692944 iov: remove copy_page_from_iter_atomic()
All callers now use copy_folio_from_iter_atomic(), so convert
copy_page_from_iter_atomic().  While I'm in there, use kmap_local_folio()
and pagefault_disable() instead of kmap_atomic().  That allows preemption
and/or task migration to happen during the copy_from_user().  Also use the
new folio_test_partial_kmap() predicate instead of open-coding it.
