MIPS: uprobes: remove incorrect set_orig_insn
Generic kernel code implements a weak version of set_orig_insn that moves cached 'insn' from arch_uprobe to the original code location when the trap is removed. MIPS variant used arch_uprobe->orig_inst which was never initialised properly, so this code only inserted a nop instead of the original instruction. With that change orig_inst can also be safely removed. Signed-off-by: Marcin Nowakowski <marcin.nowakowski@imgtec.com> Fixes: 40e084a506eb ('MIPS: Add uprobes support.')
