[PATCH 8/14] UML - Remove __u64 usage from physical memory subsystem

[Jeff Dike <jdike@addtoit.com>]

Eliminate some uses of __u64 in the physical memory support.  It's
hard to get a definition of __u64 in both kernel and userspace code on
x86_64, so this changes them to unsigned long long.

There are also a copyright update and formatting comment removal from
the affected header.
