Add UML filesystems
Please pull http://jdike.stearns.org:5000/fs-2.5 This adds the two UML-specific filesystems to 2.5. hostfs allows directories on the host to be mounted as a filesystem within a UML. hppfs allows a UML's /proc to be modified from the host. This is useful in honeypots by allowing the UML /proc to be made to look like a physical box, making it harder for an attacker to recognize a compromised box as a UML. Note that these add the filesystems under arch/um/fs since these are only usable in UML. If it would be better to have them under fs instead, then I will fix that.
