2011-12-07MIPS: irq: Remove IRQF_DISABLEDYong Zhang1-5/+5
Since commit [e58aa3d2: genirq: Run irq handlers with interrupts disabled], We run all interrupt handlers with interrupts disabled and we even check and yell when an interrupt handler returns with interrupts enabled (see commit [b738a50a: genirq: Warn when handler enables interrupts]). So now this flag is a NOOP and can be removed.

2010-04-30MIPS: die() does not call die notifier chainYury Polyanskiy2-2/+2
The MIPS implementation of die() forgets to call notify_die() and thus notifiers registered via register_die_notifier() are not called. This results in kgdb not being activated on exceptions. The only subtlety is that notify_die declares its regs argument w/o const, so the const had to be removed from mips die() as well.

2009-01-15irq: update all arches for new irq_desc, fixMike Travis2-2/+2
Impact: fix build errors Since the SPARSE IRQS changes redefined how the kstat irqs are organized, arch's must use the new accessor function: kstat_incr_irqs_this_cpu(irq, DESC); If CONFIG_SPARSE_IRQS is set, then DESC is a pointer to the irq_desc which has a pointer to the kstat_irqs. If not, then the .irqs field of struct kernel_stat is used instead. Signed-off-by: Mike Travis <travis@sgi.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
