Add some (configurable) expensive sanity checking to catch wrong address

Hmmm.. We could use include/linux/bounds.h to make
VMALLOC_START/VMALLOC_END (or whatever you need for checking the memory
boundaries) a cpp constant which may allow the use in page_32.h without
circular dependencies.
I like the idea, I'll get back with a patch in few days (sorry, too busy).
Anyway bounds.h should be include/asm/ thing though.
