Subject: [PATCH] powerpc: Fix PowerPC 750CL CPU features
Date: Thu, 12 Apr 2007 07:49:06 -0500 [thread overview]
Message-ID: <1176382146.6379.28.camel@zod.rchland.ibm.com> (raw)
PowerPC 750CL has high BATs. The patch below sets cpu_features to match that.
Without it, the original firmware mappings in the high BATs aren't cleared
which can cause "odd" address translations to occur.
