Subject: mm: page_alloc: embed OOM killing naturally into allocation slowpath fix
When retrying the allocation after potentially invoking OOM, make sure
the alloc flags are recalculated, as they have to consider TIF_MEMDIE.
Restore the original restart label, but rename it to 'retry' to match
the should_alloc_retry() it depends on.
