When we want to execute device pm functions asynchronously, we'll
do the following for the device:
1) reinit_completion(&dev->power.completion);
2) Check if the device enables asynchronous suspend.
3) If necessary, execute the corresponding function asynchronously.
There are a lot of such repeated operations here, in fact we can avoid
this. So introduce dpm_async_fn() to have better code readability and
reuse.
And use this function to do some cleanup.

Commit 2fb4719b2560 ("cpufreq / boost: Kconfig: Support for
software-managed BOOST") added the CONFIG_CPU_FREQ_BOOST_SW config.
However EXYNOS based cpufreq drivers have been removed because of
switching to cpufreq-dt driver which will set boost-attr if required.
So, let's remove this option and update cpufreq_generic_attr[].

Badly-designed systems might have (for example) active-high wake pins
that default to high (e.g., because of external pull ups) until they
have an active firmware which starts driving it low. This can cause an
interrupt storm in the time between request_irq() and disable_irq().
We don't support shared interrupts here, so let's just pre-configure the
interrupt to avoid auto-enabling it.

To be able to predict the sleep duration for a CPU entering idle, it
is essential to know the expiration time of the next timer. Both the
teo and the menu cpuidle governors already use this information for
CPU idle state selection.
Moving forward, a similar prediction needs to be made for a group of
idle CPUs rather than for a single one and the following changes
implement a new genpd governor for that purpose.
In order to support that feature, add a new function called
tick_nohz_get_next_hrtimer() that will return the next hrtimer
expiration time of a given CPU to be invoked after deciding
whether or not to stop the scheduler tick on that CPU.
Make the cpuidle core call tick_nohz_get_next_hrtimer() right
before invoking the ->enter() callback provided by the cpuidle
driver for the given state and store its return value in the
per-CPU struct cpuidle_device, so as to make it available to code
outside of cpuidle.
Note that at the point when cpuidle calls tick_nohz_get_next_hrtimer(),
the governor's ->select() callback has already returned and indicated
whether or not the tick should be stopped, so in fact the value
returned by tick_nohz_get_next_hrtimer() always is the next hrtimer
expiration time for the given CPU, possibly including the tick (if
it hasn't been stopped).

To enable a CPU device to be attached to a PM domain managed by genpd,
make a few changes to it for convenience.
To be able to quickly find out what CPUs are attached to a genpd,
which typically becomes useful from a genpd governor as subsequent
changes are about to show, add a cpumask to struct generic_pm_domain
to be updated when a CPU device gets attached to the genpd containing
that cpumask. Also, propagate the cpumask changes upwards in the
domain hierarchy to the master PM domains. This way, the cpumask for
a genpd hierarchically reflects all CPUs attached to the topology
below it.
Finally, make this an opt-in feature, to avoid having to manage CPUs
and the cpumask for a genpd that don't need it. To that end, add
a new genpd configuration bit, GENPD_FLAG_CPU_DOMAIN.

Add a data pointer to the genpd_power_state struct, to allow a genpd
backend driver to store per-state specific data. To introduce the
pointer, change the way genpd deals with freeing of the corresponding
allocated data.
More precisely, clarify the responsibility of whom that shall free the
data, by adding a ->free_states() callback to the generic_pm_domain
structure. The one allocating the data will be expected to set the
callback, to allow genpd to invoke it from genpd_remove().

Although XOR hash function can perform very well on some special use
cases, to align with all drivers, mlx5 driver should use Toeplitz hash
by default.
Toeplitz is more stable for the general use case and it is more standard
and reliable.
On top of that, since XOR (MLX5_RX_HASH_FN_INVERTED_XOR8) gives only a
repeated 8 bits pattern. When used for udp tunneling RSS source port
manipulation it results in fixed source port, which will cause bad RSS
spread.

This reverts commit b820e6fb0978f9c2ac438c199d2bb2f35950e9c9.
Prior the commit we are reverting, checksum unnecessary was only set when
both the L3 OK and L4 OK bits are set on the CQE. This caused packets
of IP protocols such as SCTP which are not dealt by the current HW L4
parser (hence the L4 OK bit is not set, but the L4 header type none bit
is set) to go through the checksum none code, where currently we wrongly
report checksum unnecessary for them, a regression. Fix this by a revert.
Note that on our usual track we report checksum complete, so the revert
isn't expected to have any notable performance impact. Also, when we are
not on the checksum complete track, the L4 protocols for which we report
checksum none are not high performance ones, we will still report
checksum unnecessary for UDP/TCP.

When an ethernet frame with ip payload is padded, the padding octets are
not covered by the hardware checksum.
Prior to the cited commit, skb checksum was forced to be CHECKSUM_NONE
when padding is detected. After it, the kernel will try to trim the
padding bytes and subtract their checksum from skb->csum.
In this patch we fixup skb->csum for any ip packet with tail padding of
any size, if any padding found.
FCS case is just one special case of this general purpose patch, hence,
it is removed.

ACPICA commit b233720031a480abd438f2e9c643080929d144c3
ASL operation_regions declare a range of addresses that it uses. In a
perfect world, the range of addresses should be used exclusively by
the AML interpreter. The OS can use this information to decide which
drivers to load so that the AML interpreter and device drivers use
different regions of memory.
During table load, the address information is added to a global
address range list. Each node in this list contains an address range
as well as a namespace node of the operation_region. This list is
deleted at ACPI shutdown.
Unfortunately, ASL operation_regions can be declared inside of control
methods. Although this is not recommended, modern firmware contains
such code. New module level code changes unintentionally removed the
functionality of adding and removing nodes to the global address
range list.
A few months ago, support for adding addresses has been re-
implemented. However, the removal of the address range list was
missed and resulted in some systems to crash due to the address list
containing bogus namespace nodes from operation_regions declared in
control methods. In order to fix the crash, this change removes
dynamic operation_regions after control method termination.

Push getting the reference for the encoders' power domains into the
encoder get_power_domains() hook instead of doing this from the caller.
This way the encoder can store away the corresponding wakerefs.
This fixes the DSI encoder disabling, which didn't release these
power references it acquired during HW state readout.
Note that longtime ownership for the corresponding wakerefs can be thus
acquired / released in two ways. Nevertheless there is always only one
owner for them:
After HW readout (booting/system resume):
- encoder->get_power_domains() acquires
- encoder->disable*() releases
After a modeset (calling intel_atomic_commit()):
- encoder->enable*() acquires
- encoder->disable*() releases
* can be any of the encoder enable/disable hooks.
v2:
- Check that the DSI io_wakerefs are unset both during encoder HW
readout and enabling. (Chris)

If scsi cmd sglist is not suitable for DDP then csiostor driver uses
preallocated buffers for DDP, because of this data copy is required from
DDP buffer to scsi cmd sglist before calling ->scsi_done().

If the RX completion indicates RX buffers errors, the RX ring will be
disabled by firmware and no packets will be received on that ring from
that point on. Recover by resetting the device.

There is logic to check that the RX/TPA consumer index is the expected
index to work around a hardware problem. However, the potentially bad
consumer index is first used to index into an array to reference an entry.
This can potentially crash if the bad consumer index is beyond legal
range. Improve the logic to use the consumer index for dereferencing
after the validity check and log an error message.

Make sure SKBTX_HW_TSTAMP (i.e. SOF_TIMESTAMPING_TX_HARDWARE) has been
enabled for this skb. It does fix the issue where normal socks that
aren't expecting a timestamp will not wake up on select, but when a
user does want a SOF_TIMESTAMPING_TX_HARDWARE it does work.

qlcnic driver uses u16 to store SPEED_UKNOWN ethtool constant,
which is defined as -1, resulting in value truncation and
thus incorrect test results against SPEED_UNKNOWN.
For example, the following test will print "False":
u16 speed = SPEED_UNKNOWN;
if (speed == SPEED_UNKNOWN)
printf("True");
else
printf("False");
Change storage of speed to use u32 to avoid this issue.

calc_tpm2_event_size() has an invalid signature because
it returns a 'size_t' where as its signature says that
it returns 'int'.

The poll condition should only check response_length,
because reads should only be issued if there is data to read.
The response_read flag only prevents double writes.
The problem was that the write set the response_read to false,
enqued a tpm job, and returned. Then application called poll
which checked the response_read flag and returned EPOLLIN.
Then the application called read, but got nothing.
After all that the async_work kicked in.
Added also mutex_lock around the poll check to prevent
other possible race conditions.

tpm_chip_start/stop() should be also called for TPM 1.x devices on
suspend. Add that functionality back. Do not lock the chip because
it is unnecessary as there are no multiple threads using it when
doing the suspend.
