[PATCH 0/2] powerpc: HFSCR enablement for POWER8

[Michael Neuling]

Benh, 

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).

v2:
  Make description of the HFSCR more verbose as suggested by benh.
