Fix build error due to stacktrace API change. Now save_stack_trace() tries to save all kernel context, including interrupts and exception. Also some asm code are changed a bit so that we can detect the end of current context easily. Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
