linux-toradex.git/include/asm-mips/stacktrace.h, branch v2.6.20-rc4 Linux kernel for Apalis and Colibri modules [MIPS] Make unwind_stack() can dig into interrupted context 2006-10-01T22:16:59+00:00 Atsushi Nemoto anemo@mba.ocn.ne.jp 2006-09-29T09:02:51+00:00 1924600cdb3143cdcc32b6fa43325739503659b9 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.
