The request_t 'handle' member is 32-bits wide, hence use wrt_reg_dword().
Change the cast in the wrt_reg_byte() call to make it clear that a regular
pointer is casted to an __iomem pointer.
Note: 'pkt' points to I/O memory for the qlafx00 adapter family and to
coherent memory for all other adapter families.
This patch fixes the following Coverity complaint:
CID 358864 (#1 of 1): Reliance on integer endianness (INCOMPATIBLE_CAST)
incompatible_cast: Pointer &pkt->handle points to an object whose effective
type is unsigned int (32 bits, unsigned) but is dereferenced as a narrower
unsigned short (16 bits, unsigned). This may lead to unexpected results
depending on machine endianness.

Since commit 84af7a6194 ("checkpatch: kconfig: prefer 'help' over

decreasing, but there are still more than 2400 instances.
This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.
There are a variety of indentation styles found.
a) 4 spaces + '---help---'
b) 7 spaces + '---help---'
c) 8 spaces + '---help---'
d) 1 space + 1 tab + '---help---'
e) 1 tab + '---help---' (correct indentation)
f) 1 tab + 1 space + '---help---'
g) 1 tab + 2 spaces + '---help---'
In order to convert all of them to 1 tab + 'help', I ran the
following commend:

The following sequence of commands result in an incorrect failure message
being printed:
echo 0x7fffffff > /sys/module/qla2xxx/parameters/logging
modprobe target_core_mod
modprobe tcm_qla2xxx
mkdir /sys/kernel/config/target/qla2xxx

qla2xxx [0001:00:02.0]-e881:1: qla2x00_wait_for_hba_online() failed
The reason of this message is the QLA_FUNCTION_FAILED code that
qla2x00_wait_for_hba_online() returns. However, qlt_disable_vha() expects
that adapter is offlined and QLA_FUNCTION_FAILED informs about the offline
state of the adapter.
The qla2x00_abort_isp() function finishes the execution at the point of
checking the adapter's mode (for example, qla_tgt_mode_enabled()) because
of the qlt_disable_vha() calls qlt_clear_mode() method. It means that
qla2x00_abort_isp() keeps vha->flags.online is equal to zero. Finally,
qla2x00_wait_for_hba_online() checks the state of this flag and returns
QLA_FUNCTION_FAILED error code.
This patch changes the failure message which informs about adapter's
offline state.

The bitfields mpi_fw_dump_reading and mpi_fw_dumped are currently signed
which is not recommended as the representation is an implementation defined
behaviour. Fix this by making the bit-fields unsigned ints.

In NPIV environment, a NPIV host may use a queue pair created by base host
or other NPIVs, so the check for a queue pair created by this NPIV is not
correct, and can cause an abort to fail, which in turn means the NVME
command not returned. This leads to hang in nvme_fc layer in
nvme_fc_delete_association() which waits for all I/Os to be returned, which
is seen as hang in the application.

Today, upon an MPI failure AEN, on top of collecting an MPI dump, a regular
firmware dump is also taken and then chip reset. This is disruptive to IOs
and not required. Make the firmware dump collection, followed by chip
reset, optional (not done by default).
Firmware dump buffer and MPI dump buffer are independent of each
other with this change and each can have dump that was taken at two
different times for two different issues. The MPI dump is saved in a
separate buffer and is retrieved differently from firmware dump.
To collect full dump on MPI failure AEN, a module parameter is
introduced:
ql2xfulldump_on_mpifail (default: 0)

qlt_free_session_done() tries to post async PRLO / LOGO, and waits for the
completion of these async commands. If UNLOADING is set, this is doomed to
timeout, because the async logout command will never complete.
The only way to avoid waiting pointlessly is to fail posting these commands
in the first place if the driver is in UNLOADING state. In general,
posting any command should be avoided when the driver is UNLOADING.
With this patch, "rmmod qla2xxx" completes without noticeable delay.

The purpose of the UNLOADING flag is to avoid port login procedures to
continue when a controller is in the process of shutting down. It makes
sense to set this flag before starting session teardown.
Furthermore, use atomic test_and_set_bit() to avoid the shutdown being run
multiple times in parallel. In qla2x00_disable_board_on_pci_error(), the
test for UNLOADING is postponed until after the check for an already
disabled PCI board.

The original patch was to resolve the lldd being able to be unloaded
while being used to talk to the boot device of the system. However, the
end result of the original patch is that any driver unload while a nvme
controller is live via the lldd is now being prohibited. Given the module
reference, the module teardown routine can't be called, thus there's no
way, other than manual actions to terminate the controllers.
