This is the final round of mostly small fixes in our initial submit.
It's mostly minor fixes and driver updates. The only change of note
is adding a virt_boundary_mask to the SCSI host and host template to
parametrise this for NVMe devices instead of having them do a call in
slave_alloc. It's a fairly straightforward conversion except in the
two NVMe handling drivers that didn't set it who now have a virtual
infinity parameter added.

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.

According to the SAS spec, an expander device shall transmit BROADCAST
(CHANGE) from at least one phy in each expander port other than the
expander port that is the cause for transmitting BROADCAST (CHANGE).
As such, for when the link is lost for a root PHY attached to an expander
PHY, we get no broadcast event.
This causes an issue for libsas, in that we will not revalidate the domain
for these events.
As a solution, for when a root PHY is formed or deformed from a root port,
insert a broadcast event to trigger a domain revalidation.

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.

case CCISS_GETHEARTBEAT:
^
The root cause is that the _IOC macro can generate really large numbers,
which don't fit into type 'int', which is used for the cmd parameter in
the ioctls in scsi_host_template. My research into how GCC and Clang are
handling this at a low level didn't prove fruitful. However, looking at
the rest of the kernel tree, all ioctls use an 'unsigned int' for the
cmd parameter, which will fit all of the _IOC values in the scsi/ata
subsystems.
Make that change because none of the ioctls expect a negative value for
any command, it brings the ioctls inline with the reset of the kernel,
and it removes ambiguity, which is never good when dealing with compilers.

The same effects can be achieved by setting the dma_boundary to
PAGE_SIZE - 1 and the max_segment_size to PAGE_SIZE, so shift those
settings into the drivers. Note that in many cases the setting might
be bogus, but this keeps the status quo.

Most SCSI drivers want to enable "clustering", that is merging of

Smatch generates a warning:
drivers/scsi/scsi_lib.c:1656 scsi_mq_done() warn: test_bit() takes a bit number
The problem is that SCMD_STATE_COMPLETE is supposed to be bit number 0
and not a mask like "(1 << 0)". It is used like this:
if (test_and_set_bit(SCMD_STATE_COMPLETE, &scmd->state))
The test_and_set_bit() has a shift built in so it's a double left shift
and uses bit number 1 instead of number 0. This bug is harmless because
it's done consistently and it doesn't clash with any other flags.

The scsi timeout error handling had been directly updating the block
layer's request state to prevent a error handling and a natural completion
from completing the same request twice. Fix this layering violation
by having scsi control the fate of its commands with scsi owned flags
rather than use blk-mq's.

hisi_sas, smartpqi, megaraid_sas, arcmsr. In addition, with the
continuing absence of Nic we have target updates for tcmu and target
core (all with reviews and acks). The biggest observable change is
going to be that we're (again) trying to switch to mulitqueue as the
default (a user can still override the setting on the kernel command
line). Other major core stuff is the removal of the remaining
Microchannel drivers, an update of the internal timers and some
reworks of completion and result handling.

To avoid introducing problems like those fixed in commit f7068114d4
("sr: pass down correctly sized SCSI sense buffer"), this creates a macro
wrapper for scsi_execute() that verifies the size of the sense buffer
similar to what was done for command string sizes in commit 3756f6401c
("exec: avoid gcc-8 warning for get_task_comm").
Another solution could be to add a length argument to scsi_execute(),
but this function already takes a lot of arguments and Jens was not fond
of that approach.
Additionally, this moves the SCSI_SENSE_BUFFERSIZE definition into
scsi_device.h, and removes a redundant include for scsi_device.h from
scsi_cmnd.h.
