+Subject: [PATCH 6/7] scsi: lpfc: Fix oops when fewer hdwqs than cpus
+
+When tearing down the adapter for a reset, online/offline, or driver
+unload, the queue free routine would hit a GPF oops.  This only occurs on
+conditions where the number of hardware queues created is fewer than the
+number of cpus in the system. In this condition cpus share a hardware
+queue. And of course, it's the 2nd cpu that shares a hardware that
+attempted to free it a second time and hit the oops.
+
+Fix by reworking the cpu to hardware queue mapping such that:
+Assignment of hardware queues to cpus occur in two passes:
+first pass: is first time assignment of a hardware queue to a cpu.
+  This will set the LPFC_CPU_FIRST_IRQ flag for the cpu.
+second pass: for cpus that did not get a hardware queue they will
+  be assigned one from a primary cpu (one set in first pass).
+
+Deletion of hardware queues is driven by cpu itteration, and queues
+will only be deleted if the LPFC_CPU_FIRST_IRQ flag is set.
+
+Also contains a few small cleanup fixes and a little better logging.
