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: (39 commits) [SCSI] qla2xxx: Update version number to 8.02.00-k5. [SCSI] qla2xxx: Correct display of ISP serial-number. [SCSI] qla2xxx: Correct residual-count handling discrepancies during UNDERRUN handling. [SCSI] qla2xxx: Make driver (mostly) legacy I/O port free. [SCSI] qla2xxx: Fix issue where final flash-segment updates were falling into the slow-path write handler. [SCSI] qla2xxx: Handle unaligned sector writes during NVRAM/VPD updates. [SCSI] qla2xxx: Defer explicit interrupt-polling processing to init-time scenarios. [SCSI] qla2xxx: Resync with latest HBA SSID specification -- 2.2u. [SCSI] sym53c8xx: Remove sym_xpt_async_sent_bdr [SCSI] sym53c8xx: Remove pci_dev pointer from sym_shcb [SCSI] sym53c8xx: Make interrupt handler capable of returning IRQ_NONE [SCSI] sym53c8xx: Get rid of IRQ_FMT and IRQ_PRM [SCSI] sym53c8xx: Use scmd_printk where appropriate [SCSI] sym53c8xx: Simplify DAC DMA handling [SCSI] sym53c8xx: Remove tag_ctrl module parameter [SCSI] sym53c8xx: Remove io_ws, mmio_ws and ram_ws elements [SCSI] sym53c8xx: Remove ->device_id [SCSI] sym53c8xx: Use pdev->revision [SCSI] sym53c8xx: PCI Error Recovery support [SCSI] sym53c8xx: Stop overriding scsi_done ...
