The driver is unable to successfully login with remote device. During pt2pt
login, the driver completes its FLOGI request with the remote device having
WWN precedence. The remote device issues its own (delayed) FLOGI after
accepting the driver's and, upon transmitting the FLOGI, immediately
recognizes it has already processed the driver's FLOGI thus it transitions
to sending a PLOGI before waiting for an ACC to its FLOGI.
In the driver, the FLOGI is received and an ACC sent, followed by the PLOGI
being received and an ACC sent. The issue is that the PLOGI reception
occurs before the response from the adapter from the FLOGI ACC is
received. Processing of the PLOGI sets state flags to perform the REG_RPI
mailbox command and proceed with the rest of discovery on the port. The
same completion routine used by both FLOGI and PLOGI is generic in
nature. One of the things it does is clear flags, and those flags happen to
drive the rest of discovery. So what happened was the PLOGI processing set
the flags, the FLOGI ACC completion cleared them, thus when the PLOGI ACC
completes it doesn't see the flags and stops.
Fix by modifying the generic completion routine to not clear the rest of
discovery flag (NLP_ACC_REGLOGIN) unless the completion is also associated
with performing a mailbox command as part of its handling. For things such
as FLOGI ACC, there isn't a subsequent action to perform with the adapter,
thus there is no mailbox cmd ptr. PLOGI ACC though will perform REG_RPI
upon completion, thus there is a mailbox cmd ptr.

Some systems are reporting the following log message during driver unload
or system shutdown:
ics_rtas_set_affinity: No online cpus in the mask
A prior commit introduced the writing of an empty affinity mask in calls to
irq_set_affinity_hint() when disabling interrupts or when there are no
remaining online CPUs to service an eq interrupt. At least some ppc64
systems are checking whether affinity masks are empty or not.
Do not call irq_set_affinity_hint() with an empty CPU mask.

Commit 98aee70d19a7 ("qla2xxx: Add endianizer to max_payload_size
modifier.") in 2014 broke qla2xxx on sparc64, e.g. as in the Sun Blade 1000

default initialization. Also mark the second frame_payload_size in nvram_t
__le16 to avoid new sparse warnings.

When multiple adapters are present in the system, pci hot-removing second
adapter leads to the following warning as both the adapters registered
thermal zone device with same thermal zone name/type.
Therefore, use unique thermal zone name during thermal zone device
initialization. Also mark thermal zone dev NULL once unregistered.

It's writing too much data. regmap_bulk_write expects number of
register sized chunks to write, not a byte sized length of the
bounce buffer. Bounce buffer needs to be padded too, so that
regmap_bulk_write will not read past the end of the buffer.

While reviewing a separate patch, I noticed that the formatting of the
commands, variables, and arguments was not in a monospaced font like the
rest of the Kbuild documentation (see kbuild/kconfig.rst for an
example). This is due to a lack of "::" before indented command blocks
and single backticks instead of double backticks for inline formatting.
Add those so that the document looks nicer in an HTML format, while not
ruining the look in plain text.
As a result of this, we can remove the escaped backslashes in the last
code block and move them to single backslashes.

First set of IIO fixes for the 5.9 cycle
Most of the fixes this time are for a long term issue that Lars-Peter
Clausen identified recently.
IIO assumes that any data pushed to the buffer interface (either kfifo
or another in kernel consumer) are naturally aligned. Unfortunately
this isn't true in a number of drivers, mostly by failing to ensure
the buffer used is aligned suitably for an s64 timestamp.
For the ones covered this time we use a structure to enforce this
alignment, with the added need for __aligned(8) to ensure 8 byte
alignment of the timestamp on x86_32 and similar platforms where
it would be 4 byte aligned giving different padded from some other
architectures.
Patches to make this requirement clearer and potentially cause an
error print will follow once we've cleaned up existing cases.
Note that it is a very hard to hit problem and as a result of this
as we only have one bug report despite the problem being present
for many years.
Other fixes:
* cros_ec:
- set gyroscope default frequency. For some older boards not having
this set can lead to a choice that doesn't work.

The basic permission bits (protection bits in AmigaOS) have been broken
in Linux' AFFS - it would only set bits, but never delete them.
Also, contrary to the documentation, the Archived bit was not handled.
Let's fix this for good, and set the bits such that Linux and classic
AmigaOS can coexist in the most peaceful manner.
Also, update the documentation to represent the current state of things.

On the older-gen 32-bit SoCs the meson-saradc driver is used to read the
SoC temperature. This requires reading calibration data from the eFuse.
Looking up the calibration data nvmem-cell requires the OF device_node
pointer to be available in the struct device which is passed to
devm_nvmem_cell_get(). This however got lost with commit 8cb631ccbb1952
("iio: Remove superfluous of_node assignments") from indio_dev->dev. As
devm_nvmem_cell_get() is called in the initialization phase the
device_node is not yet available because the NVMEM cell is looked up
before iio_device_register() is called (which would then set the
device_node automatically).
Use the parent device to look up the NVMEM cell instead to fix this
issue.

One of a class of bugs pointed out by Lars in a recent review.
iio_push_to_buffers_with_timestamp assumes the buffer used is aligned
to the size of the timestamp (8 bytes). This is not guaranteed in
this driver which uses an array of smaller elements on the stack.
As Lars also noted this anti pattern can involve a leak of data to
userspace and that indeed can happen here. We close both issues by
moving to a suitable structure in the iio_priv() data.
This data is allocated with kzalloc so no data can leak apart
from previous readings.
The explicit alignment of ts is necessary to ensure correct padding
on architectures where s64 is only 4 bytes aligned such as x86_32.

One of a class of bugs pointed out by Lars in a recent review.
iio_push_to_buffers_with_timestamp assumes the buffer used is aligned
to the size of the timestamp (8 bytes). This is not guaranteed in
this driver which uses a 32 byte array of smaller elements on the stack.
As Lars also noted this anti pattern can involve a leak of data to
userspace and that indeed can happen here. We close both issues by
moving to a suitable structure in the iio_priv() data with alignment
explicitly requested. This data is allocated with kzalloc so no
data can leak apart from previous readings. The explicit alignment
isn't technically needed here, but it reduced fragility and avoids
cut and paste into drivers where it will be needed.
If we want this in older stables will need manual backport due to
driver reworks.

dev_pm_opp_remove_table() should drop a reference to the OPP table only
if the DT OPP table was parsed earlier with a call to
dev_pm_opp_of_add_table() earlier. Else it may end up dropping the
reference to the OPP table, which was added as a result of other calls
like dev_pm_opp_set_clkname(). And would hence result in undesirable
behavior later on when caller would try to free the resource again.

The Saitek X52 family of joysticks has a pair of axes that were
originally (by the Windows driver) used as mouse pointer controls. The
corresponding usage page is the Game Controls page, which is not
recognized by the generic HID driver, and therefore, both axes get
mapped to ABS_MISC. The quirk makes the second axis get mapped to
ABS_MISC+1, and therefore made available separately.
One Saitek X52 device is already fixed. This patch fixes the other two
known devices with VID/PID 06a3:0255 and 06a3:0762.

The USB composition, defining the set of exported functions, is dynamic
in newer Quectel modems. Default functions can be disabled and
alternative functions can be enabled instead. The alternatives
includes class functions using interface pairs, which should be
handled by the respective class drivers.
Active interfaces are numbered consecutively, so static
blacklisting based on interface numbers will fail when the
composition changes. An example of such an error, where the
option driver has bound to the CDC ECM data interface,
preventing cdc_ether from handling this function:

The 'this_cpu_ptr()' is used to obtain the AEAD key' TFM on the current
CPU for encryption, however the execution can be preemptible since it's
actually user-space context, so the 'using smp_processor_id() in
preemptible' has been observed.
We fix the issue by using the 'get/put_cpu_ptr()' API which consists of
a 'preempt_disable()' instead.

Even if support for the IPU was compiled in, we may run on a device
(e.g. the Qi LB60) where the IPU is not available, or simply with an old
devicetree without the IPU node. In that case the ingenic-drm refused to
probe.
Fix the driver so that it will probe even if the IPU node is not present
in devicetree (but then IPU support is disabled of course).

Pull x86 fixes from Thomas Gleixner:
"Three interrupt related fixes for X86:
- Move disabling of the local APIC after invoking fixup_irqs() to
ensure that interrupts which are incoming are noted in the IRR and
not ignored.
- Unbreak affinity setting.
The rework of the entry code reused the regular exception entry
code for device interrupts. The vector number is pushed into the
errorcode slot on the stack which is then lifted into an argument
and set to -1 because that's regs->orig_ax which is used in quite
some places to check whether the entry came from a syscall.
But it was overlooked that orig_ax is used in the affinity cleanup
code to validate whether the interrupt has arrived on the new
target. It turned out that this vector check is pointless because
interrupts are never moved from one vector to another on the same
CPU. That check is a historical leftover from the time where x86
supported multi-CPU affinities, but not longer needed with the now
strict single CPU affinity. Famous last words ...
- Add a missing check for an empty cpumask into the matrix allocator.
The affinity change added a warning to catch the case where an
interrupt is moved on the same CPU to a different vector. This
triggers because a condition with an empty cpumask returns an
assignment from the allocator as the allocator uses for_each_cpu()
without checking the cpumask for being empty. The historical
inconsistent for_each_cpu() behaviour of ignoring the cpumask and
unconditionally claiming that CPU0 is in the mask struck again.
Sigh.

Most of the CPU mask operations behave the same way, but for_each_cpu() and
it's variants ignore the cpumask argument and claim that CPU0 is always in
the mask. This is historical, inconsistent and annoying behaviour.
The matrix allocator uses for_each_cpu() and can be called on UP with an
empty cpumask. The calling code does not expect that this succeeds but
until commit e027fffff799 ("x86/irq: Unbreak interrupt affinity setting")
this went unnoticed. That commit added a WARN_ON() to catch cases which
move an interrupt from one vector to another on the same CPU. The warning
triggers on UP.
Add a check for the cpumask being empty to prevent this.

Commit ef91bb196b0d ("kernel.h: Silence sparse warning in
lower_32_bits") caused new warnings to show in the fsldma driver, but
that commit was not to blame: it only exposed some very incorrect code
that tried to take the low 32 bits of an address.
That made no sense for multiple reasons, the most notable one being that
that code was intentionally limited to only 32-bit ppc builds, so "only
low 32 bits of an address" was completely nonsensical. There were no
high bits to mask off to begin with.
But even more importantly fropm a correctness standpoint, turning the
address into an integer then caused the subsequent address arithmetic to
be completely wrong too, and the "+1" actually incremented the address
by one, rather than by four.
Which again was incorrect, since the code was reading two 32-bit values
and trying to make a 64-bit end result of it all. Surprisingly, the
iowrite64() did not suffer from the same odd and incorrect model.
This code has never worked, but it's questionable whether anybody cared:
of the two users that actually read the 64-bit value (by way of some C
preprocessor hackery and eventually the 'get_cdar()' inline function),
one of them explicitly ignored the value, and the other one might just
happen to work despite the incorrect value being read.
This patch at least makes it not fail the build any more, and makes the
logic superficially sane. Whether it makes any difference to the code
_working_ or not shall remain a mystery.
