This patch sereis implements several important functionalities to run
Xen on top of Hyper-V.

See individual patches for more details.

I can only test them lightly and look at disassembly output to check
correctness at this stage. At the very least Xen on Hyper-V boots up
okay, so it is not breaking anything.

Wei.
