This patch implements sil24_restart_controller for those cases. This patch also makes sure that P...

Problem Details: Since irq.c uses smp_send_all_nop, we must define it for UP builds as well. Make it a static inline so it gets optimized away. This forces irq.c to include <asm/smp.h> though. Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>

Problem Details: - DMA boundary was being handled incorrectly. Copied the code from ata_fill_sg(), since Marvell has the same DMA boundary needs. (we can't use ata_fill_sg directly since we have different hardware descriptors) - cleaned up the SATA phy reset code, to deal with various errata
