Driver received a SCSI completion after it posted the cleanup request. This
leads to a problem that one ref count wasn't released leading to
flush_active_ios to get struck. The callback from libfc never returned and
other ports were not processed leading to APD.
Decrease the refcnt as well as try to complete if something is waiting for
completion.

Filesystem goes to read-only after continuous error injection because RQE
was handled in deferred context, leading to mismatch between CQE and RQE.
Specifically, this patch makes the following changes:
- Process the RQE with CQE in interrupt context, before putting it into
the work queue.
- Producer and consumer indices are also updated in the interrupt context
to guarantee the the order of processing.

The qla2xxx driver had this issue as well when the newer array firmware
returned the retry_delay_timer in the fcp_rsp. The bnx2fc is not handling
the masking of the scope bits either so the retry_delay_timestamp value
lands up being a large value added to the timer timestamp delaying I/O for
up to 27 Minutes. This patch adds similar code to handle this to the
bnx2fc driver to avoid the huge delay.

"This is mostly update of the usual drivers: qla2xxx, hpsa, lpfc, ufs,

The big merge conflict this time around is the SPDX licence tags.
Following discussion on linux-next, we believe our version to be more
accurate than the one in the tree, so the resolution is to take our
version for all the SPDX conflicts"
Note on the SPDX license tag conversion conflicts: the SCSI tree had
done its own SPDX conversion, which in some cases conflicted with the
treewide ones done by Thomas & co.
In almost all cases, the conflicts were purely syntactic: the SCSI tree
used the old-style SPDX tags ("GPL-2.0" and "GPL-2.0+") while the
treewide conversion had used the new-style ones ("GPL-2.0-only" and
"GPL-2.0-or-later").
In these cases I picked the new-style one.
In a few cases, the SPDX conversion was actually different, though. As
explained by James above, and in more detail in a pre-pull-request
thread:
"The other problem is actually substantive: In the libsas code Luben
Tuikov originally specified gpl 2.0 only by dint of stating:
* This file is licensed under GPLv2.
In all the libsas files, but then muddied the water by quoting GPLv2
verbatim (which includes the or later than language). So for these
files Christoph did the conversion to v2 only SPDX tags and Thomas
converted to v2 or later tags"
So in those cases, where the spdx tag substantially mattered, I took the
SCSI tree conversion of it, but then also took the opportunity to turn
the old-style "GPL-2.0" into a new-style "GPL-2.0-only" tag.
Similarly, when there were whitespace differences or other differences
to the comments around the copyright notices, I took the version from
the SCSI tree as being the more specific conversion.
Finally, in the spdx conversions that had no conflicts (because the
treewide ones hadn't been done for those files), I just took the SCSI
tree version as-is, even if it was old-style. The old-style conversions
are perfectly valid, even if the "-only" and "-or-later" versions are
perhaps more descriptive.

scsi: megaraid_sas: Remove few debug counters from IO path
...
If cb_arg alloc failed, we can't release the struct orig_io_req refcount
before we take its refcount. As Saurav said, move the srr_err label down
to avoid unnecessary refcount release and nullptr free.

The reason that there was a mismatch is that the SCSI command is actual
returned from the cleanup handler. In previous testing, the type of
cleanup notification we'd get from the CQE did not trigger the code that
returned the SCSI command. To overcome the previous behavior we would put
a reference in bnx2fc_abts_cleanup() to account for the SCSI command.
However, in cases where the SCSI command is actually off, we end up with an
extra put.
The fix for this is to only take the extra put in bnx2fc_abts_cleanup if
the completion for the cleanup times out.

For bnx2fc, the source FCoE MAC is stored in the fcoe_port struct in the
data_src_mac field. Currently this is set in fcoe_ctlr_recv_flogi which
ends up setting it by simply using fc_fcoe_set_mac() which only uses the
default FCF-MAC. We still want to store the source FCoE MAC in
port->data_src_mac but we want to snoop the FLOGI response payload so as to
set it in the following method:
1. If a granted_mac is found, use that.
2. If not granted_mac is there but there is a FCF-MAP from the FCF then
create the MAC from the FCF-MAP and the destination ID from the frame.
3. If there is no FCF-MAP the use the spec. default FCF-MAP and the
destination ID from the frame.

mmiowb() is now implied by spin_unlock() on architectures that require
it, so there is no reason to call it from driver code. This patch was
generated using coccinelle:
@mmiowb@
@@
- mmiowb();
and invoked as:
$ for d in drivers include/linux/qed sound; do \
spatch --include-headers --sp-file mmiowb.cocci --dir $d --in-place; done
NOTE: mmiowb() has only ever guaranteed ordering in conjunction with
spin_unlock(). However, pairing each mmiowb() removal in this patch with
the corresponding call to spin_unlock() is not at all trivial, so there
is a small chance that this change may regress any drivers incorrectly
relying on mmiowb() to order MMIO writes between CPUs using lock-free
synchronisation. If you've ended up bisecting to this commit, you can
reintroduce the mmiowb() calls using wmb() instead, which should restore
the old behaviour on all architectures other than some esoteric ia64
systems.

commit 1917d42d14 ("fcoe: use enum for fip_mode") introduces a separate
enum for the fip_mode that shall be used during initialisation handling
until it is passed to fcoe_ctrl_link_up to set the initial fip_state. That
change was incomplete and gcc quietly converted in various places between
the fip_mode and the fip_state enum values with implicit enum conversions,
which fortunately cannot cause any issues in the actual code's execution.
clang however warns about these implicit enum conversions in the scsi
drivers. This commit consolidates the use of the two enums, guided by
clang's enum-conversion warnings.
This commit now completes the use of the fip_mode: It expects and uses
fip_mode in {bnx2fc,fcoe}_interface_create and fcoe_ctlr_init, and it calls
fcoe_ctrl_set_set() with the correct values in fcoe_ctlr_link_up(). It
also breaks the association between FIP_MODE_AUTO and FIP_ST_AUTO to
indicate these two enums are distinct.
