Merge tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI fixes from James Bottomley:
"Nine fixes: The most important core one is the dma_max_mapping_size
fix that corrects the boot problem Gunter Roeck was having. A couple
of other driver only fixes are significant, like the cxgbi selector
support addition, the alua 2 second delay and the fdomain build fix"
* tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:
scsi: scsi_dh_alua: always use a 2 second delay before retrying RTPG
scsi: ibmvfc: fix WARN_ON during event pool release
scsi: fcoe: fix a typo
scsi: megaraid_sas: Make some functions static
scsi: megaraid_sas: fix panic on loading firmware crashdump
scsi: megaraid_sas: fix spelling mistake "megarid_sas" -> "megaraid_sas"
scsi: core: fix the dma_max_mapping_size call
scsi: fdomain: fix building pcmcia front-end
scsi: target: cxgbit: add support for IEEE_8021QAZ_APP_SEL_STREAM selector
