Ahh. Fallback_alloc() does not do the check for GFP_WAIT as done in
cache_grow(). Thus interrupts are disabled when we call kmem_getpages()

Duplicate the handling of GFP_WAIT in cache_grow().
Jay could you try this patch?
The patch seems to fix the bug. I've been running about an hour with it now,
and I haven't seen any error messages. Prior to the patch, I'd see the messages
within a few minutes of starting a login session.
