The attached patch splits some memory-related procfs files into MMU and !MMU
versions and places them in separate conditionally-compiled files. A header
file local to the fs/proc/ directory is used to declare functions and the like.

Additionally, a !MMU-only proc file (/proc/maps) is provided so that master VMA
list in a uClinux kernel is viewable.
