This adds the guest portion of the hypercall infrastructure.
Version 3 now follows the beat ABI, but proposes a new
implementation style as
static inline asm functions instead of pure assembler code. That
should allow
the compiler to be more flexible and therefore a better optimization.
If people agree on that new implementation style we might merge this
code.
The current implementation of beat style hypercalls can be found in
arch/powerpc/platforms/cell/beat_hvCall.S

Any reason this isn't 'sc' ?
Also, can we make this "sc 1" so its works when we have HW hypervisor
support?
