65a29c166f [SCSI] lpfc 8.1.7: Misc Fixes
Misc Fixes:
 - Fix some sparse warnings - casts of address space
 - Fix handling of the adapter registration string. Each invocation
   was byteswapping, so every other adapter init attempt failed.
 - Correct comments and default value for the lpfc_max_luns parameter

  - removes the checks from lpfc_pci_remove_one() validating the

9290831f00 [SCSI] lpfc 8.1.4 : Introduce lpfc_reset_barrier() function for resets on dual channel adapters
Introduce lpfc_reset_barrier() function for resets on dual channel adapters

Workaround for a hardware errata on dual channel asics. There is a
potential for the chip to lock up on a reset if a shared dma engine is in
use. The (ugly) work around requires a reset process which uses a mailbox
command to synchronize the independent channels prior to the reset to
avoid the issue. Unfortunately, the timing windows required to ensure this
workaround succeeds are very specific, meaning we can't release the cpu
during the barrier.

Fix deadlock in lpfc_fdmi_tmo_handler

lpfc_fdmi_tmo_handler was calling lpfc_fdmi_cmd with the host_lock
held.  lpfc_fdmi_cmd assumes the host_lock is released as it calls functions
that acquire the host_lock.  lpfc_fdmi_tmo_handler acquired the host_lock to
protect access to work_hba_events.  This was already checked in the worker
thread so we can remove that code completely and remove access to the
host_lock.
