A required unlock_page will be missed in a very rare (but possible) race
condition. Acked by Hugh, who says:

	It'll be hard to hit because of the additional page_mapped test above,
	with truncate unmapping ptes from mms before it advances to removing
	pages from cache; but nothing to prevent it happening.

There are a few devices that use lots of ioremap space.  vmalloc space is a
showstopper problem for them.

this patch adds the vmalloc=<size> boot parameter to override
__VMALLOC_RESERVE.  The default is 128mb right now - e.g.  vmalloc=256m
doubles the size.
