9cb78c16f5 scsi: use 64-bit LUNs 
The SCSI standard defines 64-bit values for LUNs, and large arrays
employing large or hierarchical LUN numbers become more and more
common.

So update the linux SCSI stack to use 64-bit LUN numbers.

53151bbb83 [SCSI] lpfc 8.3.43: Fixed not processing task management IOCB response status 
This patch implements the changes requested by Jeremy Linton:
http://marc.info/?l=linux-scsi&m=136242124409687&w=2

The patch revises the command issuing behavior, detecting cases where the
Task Mgmt command may have completed but with a non-successful status, which it
previously treated as a successful TMF. The patch also corrects a flushing of
I/O that was done which should only be done on successful TMF completion.
