Re: [PATCH] alpha: fix page fault handling for r16-r18 targets

y git, the off-by-two bug was introduced in linux 2.1.32 when trap_a{0,1,2} fields were inserted into struct pt_regs on alpha without an appropriate dpf_reg() update. Before 2.1.32 (back to 2.1.7 when dpf_reg() was introduced) there was another off-by-one bug in dpf_reg(): r16 was written into struc
