The megaraid_sas driver supports single LUN for RAID devices. That is LUN
0. All other LUNs are unsupported. When a device scan on a logical target
with invalid LUN number is invoked through sysfs, that target ends up
getting removed.
Add LUN ID validation in the slave destroy function to avoid the target
deletion.

In commit edb854a3680b ("scsi: core: Reallocate device's budget map on
queue depth change"), the sbitmap for the device budget map may be
reallocated after the slave device depth is configured.
When the sbitmap is reallocated we use the result from
scsi_device_max_queue_depth() for the sbitmap size, but don't resize to
match the actual device queue depth.
Fix by resizing the sbitmap after reallocating the budget sbitmap. We do
this instead of init'ing the sbitmap to the device queue depth as the user
may want to change the queue depth later via sysfs or other.

The adapter request_limit is hardcoded to be INITIAL_SRP_LIMIT which is
currently an arbitrary value of 800. Increase this value to 1024 which
better matches the characteristics of the typical IBMi Initiator that
supports 32 LUNs and a queue depth of 32.
This change also has the secondary benefit of being a power of two as
required by the kfifo API. Since, Commit ab9bb6318b09 ("Partially revert
"kfifo: fix kfifo_alloc() and kfifo_init()"") the size of IU pool for each
target has been rounded down to 512 when attempting to kfifo_init() those

The whole passthrough ioctl path looks completely broken. For example it
DMA maps the scatterlist and after that copies data to it, which is
prohibited by the DMA API contract.
Moreover, in pmcraid_alloc_sglist(), the pointer returned by a
sgl_alloc_order() call is not recorded anywhere which is pointless.
So remove the PMCRAID_PASSTHROUGH_IOCTL ioctl implementation entirely.
Should it be needed, we should reimplement it using the proper block layer

When recovering from a pci-parity error the driver is failing to re-create
queues, causing recovery to fail. Looking deeper, it was found that the
interrupt vector count allocated on the recovery was fewer than the vectors
originally allocated. This disparity resulted in CPU map entries with stale
information. When the driver tries to re-create the queues, it attempts to
use the stale information which indicates an eq/interrupt vector that was
no longer created.
Fix by clearng the cpup map array before enabling and requesting the IRQs
in the lpfc_sli_reset_slot_s4 routine().

When injecting EEH errors the port is getting hung up waiting on the node
list to empty, message number 0233. The driver is stuck at this point and
also can't unload. The driver makes transport remoteport delete calls which
try to abort I/O's, but the EEH daemon has already called the driver to
detach and the detachment has set the global FC_UNLOADING flag. There are
several code paths that will avoid I/O cleanup if the FC_UNLOADING flag is
set, resulting in transports waiting for I/O while the driver is waiting on
transports to clean up.
Additionally, during study of the list, a locking issue was found in
lpfc_sli_abort_iocb_ring that could corrupt the list.
A special case was added to the lpfc_cleanup() routine to call
lpfc_sli_flush_rings() if the driver is FC_UNLOADING and if the pci-slot
is offline (e.g. EEH).
The SLI4 part of lpfc_sli_abort_iocb_ring() is changed to use the
ring_lock. Also added code to cancel the I/Os if the pci-slot is offline
and added checks and returns for the FC_UNLOADING and HBA_IOQ_FLUSH flags
to prevent trying to send an I/O that we cannot handle.

Following EEH errors, the driver can crash or hang when deleting the
localport or when attempting to unload.
The EEH handlers in the driver did not notify the NVMe-FC transport before
tearing the driver down. This was delayed until the resume steps. This
worked for SCSI because lpfc_block_scsi() would notify the
scsi_fc_transport that the target was not available but it would not clean
up all the references to the ndlp.
The SLI3 prep for dev reset handler did the lpfc_offline_prep() and
lpfc_offline() calls to get the port stopped before restarting. The SLI4
version of the prep for dev reset just destroyed the queues and did not
stop NVMe from continuing. Also because the port was not really stopped
the localport destroy would hang because the transport was still waiting
for I/O. Additionally, a devloss tmo can fire and post events to a stopped
worker thread creating another hang condition.
lpfc_sli4_prep_dev_for_reset() is modified to call lpfc_offline_prep() and
lpfc_offline() rather than just lpfc_scsi_dev_block() to ensure both SCSI
and NVMe transports are notified to block I/O to the driver.
Logic is added to devloss handler and worker thread to clean up ndlp
references and quiesce appropriately.

Fix this by introducing the local variable port_id to store the port ID
value before executing mpt3sas_transport_port_remove(). This local variable
is then used in the call to ioc_info() instead of dereferencing the freed
port structure.

treewide: Replace zero-length arrays with flexible-array members
There are three sets of updates for 5.18 in the asm-generic tree:
- The set_fs()/get_fs() infrastructure gets removed for good. This
was already gone from all major architectures, but now we can
finally remove it everywhere, which loses some particularly
tricky and error-prone code.
There is a small merge conflict against a parisc cleanup, the
solution is to use their new version.
- The nds32 architecture ends its tenure in the Linux kernel. The
hardware is still used and the code is in reasonable shape, but
the mainline port is not actively maintained any more, as all
remaining users are thought to run vendor kernels that would never
be updated to a future release.
There are some obvious conflicts against changes to the removed
files.
- A series from Masahiro Yamada cleans up some of the uapi header
files to pass the compile-time checks.

Commit 01d0c698536f ("sr: implement ->free_disk to simplify refcounting")
refactored sr_block_open(), initialized one variable with a duplicate
assignment (probably an unintended copy & paste duplication) and turned one
error case into an early return, which makes the initialization of the
return variable needless.
So, simplify the local variable initialization in sr_block_open() to make
the code a bit more clear.

When aborting a SCSI command through fnic, there is a race with the fnic
interrupt handler which can result in the SCSI command and its request
being completed twice. If the interrupt handler claims the command by
setting CMD_SP to NULL first, the abort handler assumes the interrupt
handler has completed the command and returns SUCCESS, causing the request
for the scsi_cmnd to be re-queued.
But the interrupt handler may not have finished the command yet. After it
drops the spinlock protecting CMD_SP, it does memory cleanup before finally
calling scsi_done() to complete the scsi_cmnd. If the call to scsi_done
occurs after the abort handler finishes and re-queues the request, the
completion of the scsi_cmnd will advance and try to double complete a
request already queued for retry.
This patch fixes the issue by moving scsi_done() and any other use of
scsi_cmnd to before the spinlock is released by the interrupt handler.

This patch refactors the BSG paths to use SLI-4 as the primary interface.
- Conversion away from using SLI-3 iocb structures to set/access fields in
common routines. Use the new generic get/set routines that were added.
This move changes code from indirect structure references to using local
variables with the generic routines.
- Refactor routines when setting non-generic fields, to have both SLI3 and
