We currently allocate a workqueue per host and only use it for removing the
target. For the session per host case we could be using this workqueue to
be able to do recoveries (block, unblock, timeout handling) in parallel. To
also allow offload drivers to do their session recoveries in parallel, this
drops the per host workqueue and replaces it with a per session one.

Instead of storing the iSCSI task pointer and the session age in the SCSI
pointer, use command-private variables. This patch prepares for removal of
the SCSI pointer from struct scsi_cmnd.
The list of iSCSI drivers has been obtained as follows:
$ git grep -lw iscsi_host_alloc
drivers/infiniband/ulp/iser/iscsi_iser.c
drivers/scsi/be2iscsi/be_main.c
drivers/scsi/bnx2i/bnx2i_iscsi.c
drivers/scsi/cxgbi/libcxgbi.c
drivers/scsi/iscsi_tcp.c
drivers/scsi/libiscsi.c
drivers/scsi/qedi/qedi_main.c
drivers/scsi/qla4xxx/ql4_os.c
include/scsi/libiscsi.h
Note: it is not clear to me how the qla4xxx driver can work without this
patch since it uses the scsi_cmnd::SCp.ptr member for two different
purposes:
- The qla4xxx driver uses this member to store a struct srb pointer.
- libiscsi uses this member to store a struct iscsi_task pointer.

There is a regular need in the kernel to provide a way to declare
having a dynamically sized set of trailing elements in a structure.
Kernel code should always use “flexible array members”[1] for these
cases. The older style of one-element or zero-length arrays should
no longer be used[2].
This code was transformed with the help of Coccinelle:
(next-20220214$ spatch --jobs $(getconf _NPROCESSORS_ONLN) --sp-file script.cocci --include-headers --dir . > output.patch)
@@
identifier S, member, array;
type T1, T2;
@@
struct S {
...
T1 member;
T2 array[
- 0
];
};
UAPI and wireless changes were intentionally excluded from this patch
and will be sent out separately.

The 0-element arrays that are used as memcpy() destinations are actually
flexible arrays. Adjust their structures accordingly so that memcpy()
can better reason able their destination size (i.e. they need to be seen
as "unknown" length rather than "zero").
In some cases, use of the DECLARE_FLEX_ARRAY() helper is needed when a
flexible array is alone in a struct.

The macros cpu_to_le16() and cpu_to_le32() have special cases for
constants. Their __constant_<foo> versions are not required.
On little endian systems, both cpu_to_le16() and __constant_cpu_to_le16()
expand to the same expression. Same is the case with cpu_to_le32().
On big endian systems, cpu_to_le16() expands to __swab16() which has a
__builtin_constant_p check. Similarly, cpu_to_le32() expands to __swab32().
Consequently these macros can be safely used with constants, and hence all
those uses are converted. This was discovered as a part of a checkpatch
evaluation, looking at all reports of WARNING:CONSTANT_CONVERSION error
type.

During ep_disconnect we have been doing iscsi_suspend_tx/queue to block new
I/O but every driver except cxgbi and iscsi_tcp can still get I/O from
__iscsi_conn_send_pdu() if we haven't called iscsi_conn_failure() before
ep_disconnect. This could happen if we were terminating the session, and
the logout timed out before it was even sent to libiscsi.
Fix the issue by adding a helper which reverses the bind_conn call that
allows new I/O to be queued. Drivers implementing ep_disconnect can use this
to make sure new I/O is not queued to them when handling the disconnect.

qla4_82xx_crb_win_lock() spins on a certain hardware state until it's
updated. At the end of each spin, if in_interrupt() is true, it does 20
loops of cpu_relax(). Otherwise, it yields the CPU.
The in_interrupt() macro is ill-defined as it does not provide what the
name suggests, and it does not catch the intended use-case here.
qla4_82xx_crb_win_lock() is always invoked with scsi_qla_host::hw_lock
acquired, with disabled interrupts. If the caller is in process context, as
in qla4_82xx_need_reset_handler(), then in_interrupt() will return false
even though it is not allowed to call schedule().
Remove the in_interrupt() check.
Change qla4_82xx_crb_win_lock() specification to a purely atomic
function. Mark it as static, remove its forward declaration, and move it
above its callers. To avoid hammering the PCI bus while spinning, use a 10
micro-second delay instead of cpu_relax().

The set of core changes here is Christoph's submission path cleanups.
These introduced a couple of regressions when first proposed so they
got held over from the initial merge window pull request to give more
testing time, which they've now had and Syzbot has confirmed the
regression it detected is fixed. The other main changes are two
driver updates (arcmsr, pm80xx) and assorted minor clean ups.

Here are some SPDX-specific changes for 5.10-rc1.
They include:
- driver fixes to make spdxcheck.pl work properly
- add GFDL licenses as "deprecated" but required due to some of
our documentation using them
- add Zlib license as "deprecated" but required because we have
code with this license in the tree.
- convert some drivers to have SPDX identifiers that previously
didn't have them.
All have been in linux-next for a very long time with no reported
issues.

pci_set_mwi() has 'warn_unused_result' so the result should be checked.
Fixes the following W=1 kernel build warning(s):
drivers/scsi/qla4xxx/ql4_init.c: In function ‘qla4xxx_pci_config’:
drivers/scsi/qla4xxx/ql4_init.c:664:6: warning: variable ‘status’ set but not used [-Wunused-but-set-variable]
And if 'status' is removed:
drivers/scsi/qla4xxx/ql4_init.c: In function ‘qla4xxx_pci_config’:
drivers/scsi/qla4xxx/ql4_init.c:666:2: warning: ignoring return value of ‘pci_set_mwi’, declared with attribute warn_unused_result [-Wunused-result]
666 | pci_set_mwi(ha->pdev);
