Subject: mm/vmalloc.c: add a schedule point to vmalloc()
It is not uncommon on busy servers to get stuck hundred of ms in vmalloc()
calls (like file descriptor expansions).
Add a cond_resched() to __vmalloc_area_node() to be gentle to
other tasks.
[akpm@xxxxxxxxxxxxxxxxxxxx: only do it for __GFP_WAIT, per David]
