Lockdep is needed for proving the spinlocks and rwlocks work fine on our platform. It also requires calling the trace_hardirqs_off() and trace_hardirqs_on() pair of routines when entering and exiting an interrupt. For OpenRISC the interrupt stack frame does not support frame pointers, so to call trace_hardirqs_on() and trace_hardirqs_off() here the macro's build up a stack frame each time. There is one necessary small change in _sys_call_handler to move interrupt enabling later so they can get re-enabled during syscall restart. This was done to fix lockdep warnings that are now possible due to this patch. Signed-off-by: Stafford Horne <shorne@gmail.com> |
