[PATCH] CRIS update: drivers
Updates to device drivers. * Use I/O and DMA allocators. * Use wait_event_interruptible instead of interrutiple_sleep_on. * Added spinlocks SMP. * Changed restore_flags to local_irq_restore etc. * Updated IDE driver include to fit 2.6.12. Signed-off-by: Mikael Starvik <starvik@axis.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
