Subject: uml: remove __u64 usage from physical memory subsystem
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.
