[PATCH 03/10] 8xx: Tag DAR with 0x00f0 to catch buggy instructions.

dcbz, dcbf, dcbi, dcbst and icbi do not set DAR when they cause a DTLB Error. Dectect this by tagging DAR with 0x00f0 at every exception exit that modifies DAR. Test for DAR=0x00f0 in DataTLBError and bail to handle_page_fault(). Signed-off-by: Joakim Tjernlund joakim.tjernl...@transmode.se ---
