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

See individual patches for more details. First few patches are generic
x86 changes. The rest is Hyper-V specific.

I've checked the assembly code as well as putting in a test patch to
make sure the hypercall interface is implemented correctly.

Wei.
