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
