[MIPS] lockdep: Add STACKTRACE_SUPPORT and enable LOCKDEP_SUPPORT Implement stacktrace interface by using unwind_stack() and enable lockdep support in Kconfig. Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

[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.

MIPS: Add new unwind_stack variant The unwind_stack_by_address variant supports unwinding based on any kernel code address. This symbol is also exported so it can be called from modules.

[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>
