EC_CMD_HOST_EVENT_GET_WAKE_MASK
As with cros_ec_cmd_xfer_status(), etc., it's not enough to simply check
for the return status of send_command() -- that only covers transport or
other similarly-fatal errors. One must also check the ->result field, to
see whether the command really succeeded. If not, we can't use the data
it returns.
The caller of cros_ec_get_host_event_wake_mask() ignores this, and so
for example, on EC's where the command is not implemented, we're using
junk (or in practice, all zeros) for our wake-mask. We should be using a
non-zero default (currently, it's supposed to be all-1's).
Fix this by checking the ->result field and returning -EPROTO for
errors.
I might label this as fixing commit 29d99b966d60 ("cros_ec: Don't signal
wake event for non-wake host events"), except that this fix alone
actually may make things worse, as it now allows for a lot more spurious
wakeups. The patch "platform/chrome: cros_ec_proto: ignore battery/AC
wakeups on old ECs" helps to mitigate this.

ECs that don't implement EC_CMD_HOST_EVENT_GET_WAKE_MASK should still
have some reasonable default mask -- otherwise, they'll treat a variety
of EC signals as spurious wakeups. Battery and AC events can be
especially common, for devices that have been sitting at full charge
plugged into AC for a long time, as they may cycle their charging off
and on, or their battery may start reporting failures as it ages.
Treating these as wakeups does not serve a useful purpose, and is
instead often counterproductive. And indeed, later ECs (that implement
the mask) don't include these events in their wake-mask.
Note that this patch doesn't do anything without the subsequent patch
("platform/chrome: cros_ec_proto: check for missing
EC_CMD_HOST_EVENT_GET_WAKE_MASK"), because
cros_ec_get_host_event_wake_mask() currently does not return an error if
EC_CMD_HOST_EVENT_GET_WAKE_MASK is not implemented.
Some additional notes:
While the EC typically knows not to wake the CPU for these unimportant
events once the CPU reaches a sleep state, it doesn't really have a way
to know that the CPU is "almost" asleep, unless it has support for
EC_CMD_HOST_SLEEP_EVENT. Alas, these older ECs do not support that
command either, so this solution is not 100% complete.

On some machines (nami), interrupt latency cause samples to appear
to be from the future and are pegged to the current time.
We would see samples with this pattern:
[t, t + ~5ms, t + ~10ms, t + ~10ms + 100us, t + ~10ms + 200us],
(current now) (current now)
(t is the last timestamp time)
Last 2 samples would be barely spread, causing applications to
complain.
We now spread the entire sequence. This is not great: in the example
the sensor was supposed to send samples every 5ms, it now appears to
send one every 2.5ms, but it is slightly closer to reality:
sampling time in the example above
At sensor level
1 2 3 4 5
+-----5ms-----+-----5ms-----+-----5ms-----+----5ms-----+---> t
Before, at host level
1 2 3 4 5
--interrupt delay------+-----5ms-----+-----5ms-----+-+-+---> t
Afer, at host level
1 2 3 4 5
--interrupt delay------+-2.5ms-+-2.5ms-+-2.5ms-+-2.5ms-+---> t

Drivers using legacy power management .suspen()/.resume() callbacks
have to manage PCI states and device's PM states themselves. They also
need to take care of standard configuration registers.
Switch to generic power management framework using a single
"struct dev_pm_ops" variable to take the unnecessary load from the driver.
This also avoids the need for the driver to directly call most of the PCI
helper functions and device power state control functions as through
the generic framework, PCI Core takes care of the necessary operations,
and drivers are required to do only device-specific jobs.

in the way of reading calibration data and converting temperature.
MT8173, MT8183, MT2701 and MT2712 belongs to version 1 thermal
system, and MT7622 belongs to version 2.
In order to handle both systems, the suffix _V1 is appended to the

Accept the DRM_FORMAT_MOD_NVIDIA_16BX2_BLOCK()
family of modifiers to handle broken userspace
Xorg modesetting and Mesa drivers. Existing Mesa
drivers are still aware of only these older
format modifiers which do not differentiate
between different variations of the block linear
layout. When the format modifier support flag was
flipped in the nouveau kernel driver, the X.org
modesetting driver began attempting to use its
format modifier-enabled framebuffer path. Because
the set of format modifiers advertised by the
kernel prior to this change do not intersect with
the set of format modifiers advertised by Mesa,
allocating GBM buffers using format modifiers
fails and the modesetting driver falls back to
non-modifier allocation. However, it still later
queries the modifier of the GBM buffer when
creating its DRM-KMS framebuffer object, receives
the old-format modifier from Mesa, and attempts
to create a framebuffer with it. Since the kernel
is still not aware of these formats, this fails.
Userspace should not be attempting to query format
modifiers of GBM buffers allocated with a non-
format-modifier-aware allocation path, but to
avoid breaking existing userspace behavior, this
change accepts the old-style format modifiers when
creating framebuffers and applying them to planes
by translating them to the equivalent new-style
modifier. To accomplish this, some layout
parameters must be assumed to match properties of
the device targeted by the relevant ioctls. To
avoid perpetuating misuse of the old-style
modifiers, this change does not advertise support
for them. Doing so would imply compatibility
between devices with incompatible memory layouts.

The function invokes bpf_prog_inc(), which increases the reference
count of a bpf_prog object "rq->xdp_prog" if the object isn't NULL.
The refcount leak issues take place in two error handling paths. When
either mlx5_wq_ll_create() or mlx5_wq_cyc_create() fails, the function
simply returns the error code and forgets to drop the reference count
increased earlier, causing a reference count leak of "rq->xdp_prog".
Fix this issue by jumping to the error handling path err_rq_wq_destroy
while either function fails.

The modified flow_context fields in FTE must be indicated in
modify_enable bitmask. Previously, the misc bit in modify_enable is
always set as source vport must be set for each rule. So, when parsing
vxlan/gre/geneve/qinq rules, this bit is not set because those are all
from the same misc fileds that source vport fields are located at, and
we don't need to set the indicator twice.
After adding per vport tables for mirroring, misc bit is not set, then
firmware syndrome happens. To fix it, set the bit wherever misc fileds
are changed. This also makes it unnecessary to check misc fields and set
the misc bit accordingly in metadata matching, so here remove it.
Besides, flow_source must be specified for uplink because firmware
will check it and some actions are only allowed for packets received
from uplink.

The SCSI midlayer does not allow state transitions from SDEV_BLOCK to
SDEV_BLOCK so calling scsi_target_block() from __rport_fast_io_fail() is
wrong as the port is already blocked. Similarly, we don't need to call
scsi_target_unblock() afterwards as the function has already done this.

Some UFS devices require delay after VCC power rail is turned off.
Introduce a device quirk "DELAY_AFTER_LPM" to add 5ms delay after VCC
power-off during suspend flow.

Commit 5ff843721467 ("scsi: virtio_scsi: unplug LUNs when events missed")
missed a corner case in which all the LUNs are unplugged at the same time.
In this case INQUIRY returns DID_BAD_TARGET. Detect this and unplug the
LUN.

platform_get_resource() may fail and return NULL, so we had better
check its return value to avoid a NULL pointer dereference a bit later
in the code. Fix it to use devm_platform_ioremap_resource_byname()
instead of calling platform_get_resource_byname() and devm_ioremap().

Drivers using legacy power management .suspen()/.resume() callbacks
have to manage PCI states and device's PM states themselves. They also
need to take care of standard configuration registers.
Switch to generic power management framework using a single
"struct dev_pm_ops" variable to take the unnecessary load from the driver.
This also avoids the need for the driver to directly call most of the PCI
helper functions and device power state control functions, as through
the generic framework PCI Core takes care of the necessary operations,
and drivers are required to do only device-specific jobs.
