[PATCH] UML filesystems

[Jeff Dike]

Please pull
	http://jdike.stearns.org:5000/fs-2.5

This adds the two UML filesystems to the 2.5 tree - hostfs allows a directory
on the host to be mounted as a filesystem inside UML, and hppfs is an overlay
over /proc which allows the content of the UML's /proc to be controlled from
the host.

These are going into fs/hostfs and fs/hppfs.

The changes here include the merge into 2.5 and subsequent bug fixes.
