Alan (4):
libata cmd64x: whack into a shape that looks like the documentation
libata hpt3xn: Hopefully sort out the DPLL logic versus the vendor code
libata: set_mode, Fix the FIXME
libata-sff: Don't call bmdma_stop on non DMA capable controllers
David Woodhouse (1):
Fix Maple PATA IRQ assignment.
Tejun Heo (6):
sata_via: don't diddle with ATA_NIEN in ->freeze
ahci: improve and limit spurious interrupt messages, take#3
libata: implement ATA_FLAG_IGN_SIMPLEX and use it in sata_uli
ahci: fix endianness in spurious interrupt message
sata_via: style clean up, no indirect method call in LLD
ahci: use 0x80 as wait stat value instead of 0xff
