[PATCH] More address space checking
* generate a warning when we cast _between_ address spaces (e.g. cast
from __user to __iomem).
* optional (on -Wcast-to-as) warning when casting _TO_ address space
(e.g. when normal pointer is cast to __iomem one - that caught a lot
of crap in drivers). casts from unsigned long are still OK, so's
cast from 0, so's __force cast, of course.
