mm: accept memory in __alloc_pages_bulk()
Currently, the kernel only accepts memory in get_page_from_freelist(), but
there is another path that directly takes pages from free lists -
__alloc_page_bulk(). This function can consume all accepted memory and
will resort to __alloc_pages_noprof() if necessary.
Conditionally accepted in __alloc_pages_bulk().
The same issue may arise due to deferred page initialization. Kick the
deferred initialization machinery before abandoning the zone, as the
kernel does in get_page_from_freelist().
