* git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi-misc-2.6: (110 commits) [SCSI] qla2xxx: Refactor call to qla2xxx_read_sfp for thermal temperature. [SCSI] qla2xxx: Unify the read/write sfp mailbox command routines. [SCSI] qla2xxx: Clear complete initialization control block. [SCSI] qla2xxx: Allow an override of the registered maximum LUN. [SCSI] qla2xxx: Add host number in reset and quiescent message logs. [SCSI] qla2xxx: Correctly read sfp single byte mailbox register. [SCSI] qla2xxx: Add qla82xx_rom_unlock() function. [SCSI] qla2xxx: Log if qla82xx firmware fails to load from flash. [SCSI] qla2xxx: Use passed in host to initialize local scsi_qla_host in queuecommand function [SCSI] qla2xxx: Correct buffer start in edc sysfs debug print. [SCSI] qla2xxx: Update firmware version after flash update for ISP82xx. [SCSI] qla2xxx: Fix hang during driver unload when vport is active. [SCSI] qla2xxx: Properly set the dsd_list_len for dsd_chaining in cmd type 6. [SCSI] qla2xxx: Fix virtual port failing to login after chip reset. [SCSI] qla2xxx: Fix vport delete hang when logins are outstanding. [SCSI] hpsa: Change memset using sizeof(ptr) to sizeof(*ptr) [SCSI] ipr: Rate limit DMA mapping errors [SCSI] hpsa: add P2000 to list of shared SAS devices [SCSI] hpsa: do not attempt PCI power management reset method if we know it won't work.
