[ARM] stacktrace fix
ab1b6f03a10ba1f5638188ab06bf46e33ac3a160 said
- remove the unused task argument to save_stack_trace, it's always current
then broke arm:
arch/arm/kernel/stacktrace.c:56: error: conflicting types for 'save_stack_trace'
include/linux/stacktrace.h:11: error: previous declaration of 'save_stack_trace' was here
