Atsushi Nemoto	1924600cdb	[MIPS] Make unwind_stack() can dig into interrupted context ... If the PC was ret_from_irq or ret_from_exception, there will be no more normal stackframe. Instead of stopping the unwinding, use PC and RA saved by an exception handler to continue unwinding into the interrupted context. This also simplifies the CONFIG_STACKTRACE code.

Atsushi Nemoto	23126692e3	[MIPS] Stacktrace build-fix and improvement ... 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.
