Ralf Baechle	a204458acb	[MIPS] unwind_stack should return a value ... ... And gcc 3.4 doesn't even warn out this, grrr. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>	18 years ago
Ralf Baechle	de4b214740	[MIPS] Fix build error if CONFIG_KALLSYMS is undefined. ... CC arch/mips/kernel/traps.o arch/mips/kernel/traps.c: In function 'show_backtrace': arch/mips/kernel/traps.c:110: warning: unused variable 'ra' Signed-off-by: Ralf Baechle <ralf@linux-mips.org>	18 years ago
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.
