lockdep: fix irqs on/off ip tracing
Impact: fix lockdep lock-api-caller output when irqsoff tracing is enabled 81d68a96 "ftrace: trace irq disabled critical timings" added wrappers around trace_hardirqs_on/off_caller. However these functions use __builtin_return_address(0) to figure out which function actually disabled or enabled irqs. The result is that we save the ips of trace_hardirqs_on/off instead of the real caller. Not very helpful. However since the patch from Steven the ip already gets passed. So use that and get rid of __builtin_return_address(0) in these two functions. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
