From 161deaf225e70dee991744cd3164a30726a1b0eb Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Wed, 29 Jun 2016 00:35:12 +0530 Subject: [PATCH] ppc/xics: Rename existing xics to xics_spapr The common class doesn't change, the KVM one is sPAPR specific. Rename variables and functions to xics_spapr. Retain the type name as "xics" to preserve migration for existing sPAPR guests.
