From 9f0b079320ad1cc71ad7ea4e0ed0b64cd72bbd6d Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Thu, 7 Apr 2011 21:56:03 +0000 Subject: powerpc: Use MSR_64BIT in places Use the new MSR_64BIT in a few places. Some of these are already ifdef'ed for BOOKE vs BOOKS, but it's still clearer, MSR_SF does not immediately parse as "MSR bit for 64bit".
