This small series adds support for the HFSCR (Hypervisor Facility Status &
Control Register) in POWER8. It just sets the bits we know about at this
stage. This is useful only when MSR HV=1.
The HFSCR is the same as the FSCR except it's for hypervisors. It controls the
available of various facilities in OS and userspace levels. It also indicates
the cause of a hypervisor facility unavailable interrupt (although we are not
using this here).
Make description of the HFSCR more verbose as suggested by benh.
