Subject: [PATCH 0/2] powerpc: HFSCR enablement for POWER8
Date: Wed,  6 Mar 2013 14:35:22 +1100	[thread overview]
Message-ID: <1362540924-15253-1-git-send-email-mikey@neuling.org> (raw)

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.

Mikey
