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

See individual patches for more details. The first patch adds an
executable fixmap facility, which is x86 generic. The rest of the series
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.
