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.

e12f0a3dec [SCSI] sr: partial revert of 24669f75a3
The patch

[SCSI] SCSI core kmalloc2kzalloc

Has an incorrect piece in sr_ioctl.c; it changes buffer from kmalloc
to kzalloc, but then removes the clearing of the stack variable struct
packet_command.  This, in turn leaves rubbish in the sense pointer
which the sr_do_ioctl() command then happily writes to ... oops.

Thanks to Mike Christie <michaelc@cs.wisc.edu> for spotting this.

Ok, so here is my first take at satisfying this request.
Be warned, that beyond compiling, and checking that the new module
doesn't immediately blow up, there hasn't yet been a lot of testing.

But this should allow you to comment on the changes, and move forward
with dropping scsi_request from the kernel code.

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.
