[PATCH] irq-flags: consolidate flags for request_irq
The recent interrupt rework introduced bit value conflicts with sparc. Instead of introducing new architecture flags mess, move the interrupt SA_ flags out of the signal namespace and replace them by interrupt related flags. This allows to remove the obsolete SA_INTERRUPT flag and clean up the bit field values. This patch: Move the interrupt related SA_ flags out of linux/signal.h and rename them to IRQF_ . This moves the interrupt related flags out of the signal namespace and allows to remove the architecture dependencies. SA_INTERRUPT is not needed by userspace and glibc so it can be removed safely. The existing SA_ constants are kept for easy transition and will be removed after a 6 month grace period.
