Merge master.kernel.org:/pub/scm/linux/kernel/git/jejb/scsi-misc-2.6
* master.kernel.org:/pub/scm/linux/kernel/git/jejb/scsi-misc-2.6: (85 commits) [SCSI] 53c700: remove reliance on deprecated cmnd fields [SCSI] hptiop: don't use cmnd->bufflen [SCSI] hptiop: HighPoint RocketRAID 3xxx controller driver [SCSI] aacraid: small misc. cleanups [SCSI] aacraid: Update supported product information [SCSI] aacraid: Fix return code interpretation [SCSI] scsi_transport_sas: fix panic in sas_free_rphy [SCSI] remove RQ_SCSI_* flags [SCSI] remove scsi_request infrastructure [SCSI] mptfusion: change driver revision to 3.03.10 [SCSI] mptfc: abort of board reset leaves port dead requiring reboot [SCSI] mptfc: fix fibre channel infinite request/response loop [SCSI] mptfc: set fibre channel fw target missing timers to one second [SCSI] mptfusion: move fc event/reset handling to mptfc [SCSI] spi transport: don't allow dt to be set on SE or HVD buses [SCSI] aic7xxx: expose the bus setting to sysfs [SCSI] scsi: remove Documentation/scsi/cpqfc.txt [SCSI] drivers/scsi: Use ARRAY_SIZE macro [SCSI] Remove last page_address from dc395x.c [SCSI] hptiop: HighPoint RocketRAID 3xxx controller driver ... Fixed up conflicts in drivers/message/fusion/mptbase.c manually (due to the sparc interrupt cleanups)
