From e0622bd9f2fccc8a801fa7aaf4fa6d7c728c3a78 Mon Sep 17 00:00:00 2001 From: Paul Mackerras Date: Wed, 8 Jan 2014 21:25:27 +1100 Subject: KVM: PPC: Book3S HV: Handle new LPCR bits on POWER8 POWER8 has a bit in the LPCR to enable or disable the PURR and SPURR registers to count when in the guest. Set this bit. POWER8 has a field in the LPCR called AIL (Alternate Interrupt Location) which is used to enable relocation-on interrupts. Allow userspace to set this field.
