The ISA support in Buslogic has been broken for a long time, as all
the I/O path expects a struct device for DMA mapping that is derived from
the PCI device, which would simply crash for ISA adapters.

To remove the last user of the unchecked_isa_dma flag and thus the block
layer ISA bounce buffering switch this driver to use its own local bounce
buffer. This has the effect of not needing the chain indirection and
supporting and unlimited number of segments. It does however limit the
transfer size for each command to something that can be reasonable
allocated by dma_alloc_coherent like 8K.

Fix the following out-of-bounds warnings by enclosing some structure
members into new structure objects upiu_req and upiu_rsp:
include/linux/fortify-string.h:20:29: warning: '__builtin_memcpy' offset [29, 48] from the object at 'treq' is out of the bounds of referenced subobject 'req_header' with type 'struct utp_upiu_header' at offset 16 [-Warray-bounds]

Refactor the code by making it more structured.
The problem is that the original code is trying to copy data into a bunch
of struct members adjacent to each other in a single call to memcpy(). Now
that a new struct _upiu_req_ enclosing all those adjacent members is
introduced, memcpy() doesn't overrun the length of &treq.req_header,
because the address of the new struct object _upiu_req_ is used as the
destination, instead. The same problem is present when memcpy() overruns
the length of the source &treq.rsp_header; in this case the address of the
new struct object _upiu_rsp_ is used, instead.
Also, this helps with the ongoing efforts to enable -Warray-bounds and
avoid confusing the compiler.

While diag reset is in progress there is short duration where all access to
controller's PCI config space from the host needs to be blocked. This is
due to a hardware limitation of the IOC controllers.
Block all access to controller's config space from userland applications by
calling pci_cfg_access_lock() while diag reset is in progress and unlocking
it again after the controller comes back to ready state.

Enhance performance by adding sequential stream detection for RAID5/RAID6
sequential write requests. Reduce stripe lock contention with full-stripe
write operations.
There is one common stripe lock for each RAID volume that can be set by
either the RAID engine or the AIO engine. The AIO path has I/O request
sizes well below the stripe size resulting in many Read-Modify-Write
operations.
Sending the request to the RAID engine allows for coalescing requests into
full stripe operations resulting in reduced Read-Modify-Write operations.

Boot failure was observed on an HP rx3600 ia64 machine with RAID bus

kernel unaligned access to 0xe000000105dd8b95, ip=0xa000000100b87551

swapper/0[1]: error during unaligned kernel access
The unaligned access comes from 'struct CommandList' that happens to be
packed. Commit f749d8b7a9 ("scsi: hpsa: Correct dev cmds outstanding for
retried cmds") introduced unexpected padding and unaligned atomic_t from
natural alignment to something else.
This change removes packing annotation from a struct not intended to be
sent to controller as is. This restores natural `atomic_t` alignment.
The change was tested on the same rx3600 machine.

The hpsa driver uses data structures which contain a combination of driver
internals and commands sent directly to the hardware. To manage alignment
for the hardware portions the driver used #pragma pack(1).
Commit f749d8b7a9 ("scsi: hpsa: Correct dev cmds outstanding for retried
cmds") switched an existing variable from int to bool. Due to the pragma an
atomic_t in the same data structure ended up being misaligned and broke
boot on ia64.
Add __packed to every struct and union in the header file. Subsequent
commits will address the actual atomic_t misalignment regression.
The commit is a no-op at least on ia64:

Commit b43abcbbd5 ("scsi: fnic: Ratelimit printks to avoid flooding when

couple of debug-mode messages to reduce logging overrun when debugging the
driver. The code:
> if (printk_ratelimit())
> FNIC_FCS_DBG(KERN_DEBUG, fnic->lport->host,
> "Start VLAN Discovery\n");
ends up calling printk_ratelimit() quite often, triggering many kernel
messages about callbacks being supressed.
The fix is to decompose FNIC_FCS_DBG(), then change the order of checks so
that printk_ratelimit() is only called if driver debugging is enabled.

Session was stuck due to explicit logout to target timing out. The target
was in an unresponsive state. This timeout induced an error to the GNL
command from moving forward.

A kernel panic was observed due to a timing issue between the sync thread
and the initiator processing a login response from the target. The session
reopen can be invoked both from the session sync thread when iscsid
restarts and from iscsid through the error handler. Before the initiator
receives the response to a login, another reopen request can be sent from
the error handler/sync session. When the initial login response is
subsequently processed, the connection has been closed and the socket has
been released.
To fix this a new connection state, ISCSI_CONN_BOUND, is added:
- Set the connection state value to ISCSI_CONN_DOWN upon
iscsi_if_ep_disconnect() and iscsi_if_stop_conn()
- Set the connection state to the newly created value ISCSI_CONN_BOUND
after bind connection (transport->bind_conn())
- In iscsi_set_param(), return -ENOTCONN if the connection state is not
either ISCSI_CONN_BOUND or ISCSI_CONN_UP

I first assumed this was a gcc bug, as that should not happen, but a
reduced test case makes it clear that this happens when the loop counter is
not bounded by the array size.
Help the compiler out by adding an explicit limit here to make the code
slightly more robust and avoid the warning.

Instead of strcpy'ing into a stack buffer, just let additional_notice point
to a string literal living in .rodata. This is better in a few ways:
- Smaller .text - instead of gcc compiling the strcpys as a bunch of
immediate stores (effectively encoding the string literal in the
instruction stream), we only pay the price of storing the literal in
.rodata.
- Faster, because there's no string copying.
- Smaller stack usage (with my compiler, 72 bytes instead of 176 for the
sole caller, bnx2i_indicate_kcqe)
Moreover, it's currently possible for additional_notice[] to get used
uninitialized, so some random stack garbage would be passed to printk() -
in the worst case without any '\0' anywhere in those 64 bytes. That could
be fixed by initializing additional_notice[0], but the same is achieved
here by initializing the new pointer variable to "".
Also give the message pointer a similar treatment - there's no point making
temporary copies on the stack of those two strings.

Calling vha->hw->tgt.tgt_ops->free_cmd() from qlt_xmit_response() is wrong
since the command for which a response is sent must remain valid until the
SCSI target core calls .release_cmd(). It has been observed that the
following scenario triggers a kernel crash:
- qlt_xmit_response() calls qlt_check_reserve_free_req()
- qlt_check_reserve_free_req() returns -EAGAIN
- qlt_xmit_response() calls vha->hw->tgt.tgt_ops->free_cmd(cmd)
- transport_handle_queue_full() tries to retransmit the response
Fix this crash by reverting the patch that introduced it.

During MQ enablement of the ibmvfc driver ibmvfc_wait_for_ops() was
missed. This function is responsible for waiting on commands to complete
that match a certain criteria such as LUN or cancel key. The implementation
as is only scans the CRQ for events ignoring any sub-queues and as a result
will exit successfully without doing anything when operating in MQ
channelized mode.
Check the MQ and channel use flags to determine which queues are
applicable, and scan each queue accordingly. Note in MQ mode SCSI commands
are only issued down sub-queues and the CRQ is only used for driver
specific management commands. As such the CRQ events are ignored when
operating in MQ mode with channels.

For various EH activities the ibmvfc driver uses ibmvfc_wait_for_ops() to
wait for the completion of commands that match a given criteria be it
cancel key, or specific LUN. With recent changes commands are completed
outside the lock in bulk by removing them from the sent list and adding
them to a private completion list. This introduces a potential race in
ibmvfc_wait_for_ops() since the criteria for a command to be outstanding is
no longer simply being on the sent list, but instead not being on the free
list.
Avoid this race by scanning the entire command event pool and checking that
any matching command that ibmvfc needs to wait on is not already on the
free list.
