Unless the controller is not responding at boot or after suspend/resume,
the driver never resets the controller on x86/ACPI platforms. The driver
still requesting the reset pin at probe() though in case it needs it.
Until now the driver has always requested the reset pin with GPIOD_IN
as type. The idea being to put the pin in high-impedance mode to save
power until the driver actually wants to issue a reset.
But this means that just requesting the pin can cause issues, since
requesting it in another mode then GPIOD_ASIS may cause the pinctrl
driver to touch the pin settings. We have already had issues before
due to a bug in the pinctrl-cherryview.c driver which has been fixed in
commit 921daeeca91b ("pinctrl: cherryview: Preserve
CHV_PADCTRL1_INVRXTX_TXDATA flag on GPIOs").
And now it turns out that requesting the reset-pin as GPIOD_IN also stops
the touchscreen from working on the GPD P2 max mini-laptop. The behavior
of putting the pin in high-impedance mode relies on there being some
external pull-up to keep it high and there seems to be no pull-up on the
GPD P2 max, causing things to break.
This commit fixes this by requesting the reset pin as is when using
the x86/ACPI code paths to lookup the GPIOs; and by not dropping it
back into input-mode in case the driver does end up issuing a reset
for error-recovery.

The ASUS UM325UA suffers from the same issue as the ASUS UX425UA, which
is a very similar laptop. The i8042 device is not usable immediately
after boot and fails to initialize, requiring a deferred retry.

Implements genpd and reset providers for downstream devices. Each
instance of the driver binds to a single register and represents a
single SoC power domain.
The driver does not currently implement all features (clockgate-only
state, misc flags), but we declare the respective registers for
documentation purposes. These features will be added as they become
useful for downstream devices.
This also creates the apple/soc tree and Kconfig submenu.

Commit 598a90f2002c ("scsi: qla2xxx: add ring buffer for tracing debug

ql_dbg_log event is disabled. It harms performance because some strings are
formatted in fastpath and/or interrupt context.

According to ZBC and SPC specifications, the unit of ALLOCATION LENGTH
field of REPORT ZONES command is byte. However, current scsi_debug
implementation handles it as number of zones to calculate buffer size to
report zones. When the ALLOCATION LENGTH has a large number, this results
in too large buffer size and causes memory allocation failure. Fix the
failure by handling ALLOCATION LENGTH as byte unit.

iavf_set_ringparams doesn't communicate to the user that
1. The user requested descriptor count is out of range. Instead it
just quietly sets descriptors to the "clamped" value and calls it
done. This makes it look an invalid value was successfully set as
the descriptor count when this isn't actually true.
2. The user provided descriptor count needs to be inflated for alignment
reasons.
This behavior is confusing. The ice driver has already addressed this
by rejecting invalid values for descriptor count and
messaging for alignment adjustments.
Do the same thing here by adding the error and info messages.

The entries in the DMA translation tables for our IOMMU must specify
physical addresses of either the next level table or the final page
to be mapped for DMA. Currently however the code simply passes the
virtual addresses of both. On the other hand we still need to walk the
tables via their virtual addresses so we need to do a phys_to_virt()
when setting the entries and a virt_to_phys() when getting them.
Similarly when passing the I/O translation anchor to the hardware we
must also specify its physical address.
As the DMA and IOMMU APIs we are implementing already use the correct
phys_addr_t type for the address to be mapped let's also thread this
through instead of treating it as just an unsigned long.
Note: this currently doesn't fix a real bug, since virtual addresses
are indentical to physical ones.

qdio_handle_activate_check() tries to re-use one of the queue-specific

logic to select that handler is overly complex - in practice both
qdio drivers have at least one Input Queue, so we never take the other
paths.
Make things more obvious by removing this unused code, and clearly
spelling out that we re-use the Input Handler for generic error

commit fa1a8c23eb7d ("s390: cio: Delay uevents for subchannels")
introduced suppression of uevents for a subchannel until after it is
clear that the subchannel would not be unregistered again
immediately. This was done to avoid uevents being generated for I/O
subchannels with no valid device, which can happen on LPAR.
However, this also has some drawbacks: All subchannel drivers need to
manually remove the uevent suppression and generate an ADD uevent as
soon as they are sure that the subchannel will stay around. This misses
out on all uevents that are not the initial ADD uevent that would be
generated while uevents are suppressed; for example, all subchannels
were missing the BIND uevent.
As uevents being generated even for I/O subchannels without an
operational device turned out to be not as bad as missing uevents and
complicating the code flow, let's remove uevent suppression for
subchannels.

The write pointer in NVMe ZNS is invalid for a zone in zone state full.
The same also holds true for ZAC/ZBC.
The current behavior for NVMe is to simply propagate the wp reported by
the drive, even for full zones. Since the wp is invalid for a full zone,
the wp reported by the drive may be any value.
The way that the sd_zbc driver handles a full zone is to always report
the wp as zone start + zone len, regardless of what the drive reported.
null_blk also follows this convention.
Do the same for NVMe, so that a BLKREPORTZONE ioctl reports the write
pointer for a full zone in a consistent way, regardless of the interface
of the underlying zoned block device.
blkzone report before patch:
start: 0x000040000, len 0x040000, cap 0x03e000, wptr 0xfffffffffffbfff8

Suppress setting the metadata feature in the namespace so that the

Currently, due to the sequential use of min_t() and clamp_t() macros,
in cdc_ncm_check_tx_max(), if dwNtbOutMaxSize is not set, the logic
sets tx_max to 0. This is then used to allocate the data area of the
SKB requested later in cdc_ncm_fill_tx_frame().
This does not cause an issue presently because when memory is
allocated during initialisation phase of SKB creation, more memory
(512b) is allocated than is required for the SKB headers alone (320b),
leaving some space (512b - 320b = 192b) for CDC data (172b).
However, if more elements (for example 3 x u64 = [24b]) were added to
one of the SKB header structs, say 'struct skb_shared_info',
increasing its original size (320b [320b aligned]) to something larger
(344b [384b aligned]), then suddenly the CDC data (172b) no longer
fits in the spare SKB data area (512b - 384b = 128b).
Consequently the SKB bounds checking semantics fails and panics:
skbuff: skb_over_panic: text:ffffffff830a5b5f len:184 put:172 \
head:ffff888119227c00 data:ffff888119227c00 tail:0xb8 end:0x80 dev:<NULL>

By overriding the max value with the default CDC_NCM_NTB_MAX_SIZE_TX
when not offered through the system provided params, we ensure enough
data space is allocated to handle the CDC data, meaning no crash will
occur.

Although it is unlikely that stack could transmit a non LSO
skb with length > MTU, however in some cases or environment such
occurrences actually resulted into firmware asserts due to packet
length being greater than the max supported by the device (~9700B).
This patch adds the safeguard for such odd cases to avoid firmware
asserts.
v2: Added "Fixes" tag with one of the initial driver commit
which enabled the TX traffic actually (as this was probably
day1 issue which was discovered recently by some customer
environment)

cgroup.h (therefore swap.h, therefore half of the universe)
includes bpf.h which in turn includes module.h and slab.h.
Since we're about to get rid of that dependency we need
to clean things up.
v2: drop the cpu.h include from cacheinfo.h, it's not necessary
and it makes riscv sensitive to ordering of include files.

Since commit 041284181226 ("of/irq: Allow matching of an interrupt-map
local to an interrupt controller"), a handful of interrupt controllers
have stopped working correctly. This is due to the DT exposing a
non-sensical interrupt-map property, and their drivers relying on the
kernel ignoring this property.
Since we cannot realistically fix this terrible behaviour, add a quirk
for the limited set of devices that have implemented this monster,
and document that this is a pretty bad practice.
