From 03054d51a70e8c273df5d9bc31fea6c843eaa1c3 Mon Sep 17 00:00:00 2001 From: Anton Blanchard Date: Sat, 29 Apr 2006 09:51:06 +1000 Subject: [PATCH] powerpc: Add cputable entry for POWER6 Add a cputable entry for the POWER6 processor. The SIHV and SIPR bits in the mmcra have moved in POWER6, so disable support for that until oprofile is fixed. Also tell firmware that we know about POWER6.
