From 32019828d9012e584017a824f84798248c0060dd Mon Sep 17 00:00:00 2001 From: Haavard Skinnemoen Date: Wed, 13 Feb 2008 12:32:34 +0100 Subject: [PATCH] avr32: Fix broken pte dump code in do_page_fault() The per-task page tables only cover the first 2GiB of the address space. For kernel addresses, we need to do the lookup in init's page tables. This is a temporary workaround until we modify the per-task page tables to cover the whole 4GiB address space.
