Juergen Gross 47ae4b05d0 virt, sched: Add generic vCPU pinning support
Add generic virtualization support for pinning the current vCPU to a
specified physical CPU. As this operation isn't performance critical
(a very limited set of operations like BIOS calls and SMIs is expected
to need this) just add a hypervisor specific indirection.
