From 06f862c8ce0893b5525ce90f39168eaf4608ecc6 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Wed, 1 Aug 2007 16:39:51 +0900 Subject: [PATCH] sh: Fix pgd mismatch from cached TTB in unhandled fault. When reading the cached TTB value and extracting the pgd, we accidentally applied a __va() to it and bumped it off in to bogus space which ended up causing multiple faults in the error path. Fix it up so unhandled faults don't do strange and highly unorthodox things when oopsing.
