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. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
