[ Upstream commit ea6055c46eda1e19e02209814955e13f334bbe1b ]
Since commit 39a6ac11df65 ("spi/pl022: Devicetree support w/o platform data")
the 'num-cs' parameter cannot be passed through platform data when probing
with devicetree. Instead, it's a required devicetree property.
Fix the binding documentation so the property is properly specified.

For networking applications, platforms need to provide one CPU per each user
space data plane thread. These CPUs shouldn't be interrupted by kernel at all
unless userspace has requested for some functionality. Currently, there are
background kernel activities that are running on almost every CPU, like:
timers/hrtimers/watchdogs/etc, and these are required to be migrated to other
CPUs.
To achieve that, this patch adds another option to cpusets, i.e. 'quiesce'.
Writing '1' on this file would migrate these unbound/unpinned timers/hrtimers
away from the CPUs of the cpuset in question. Also it would disallow addition of
any new unpinned timers/hrtimers to isolated CPUs (This would be handled in next
patch). Writing '0' will disable isolation of CPUs in current cpuset and
unpinned timers/hrtimers would be allowed in future on these CPUs.
Currently, only timers and hrtimers are migrated. This would be followed by
other kernel infrastructure later if required.

A new revision of the Marvell Armada 38x hardware datasheet unveiled

Make it possible to disable offloading writes by setting the optional
'submit_from_crypt_cpus' table argument.
There are some situations where offloading write bios from the
encryption threads to a single thread degrades performance
significantly.
The default is to offload write bios to the same thread because it
benefits CFQ to have writes submitted using the same IO context.

It is common to have a linear extrapolation from
the current sensor readings and the actual temperature
value. This is specially the case when the sensor
is in use to extrapolate hotspots.
This patch adds slope and offset constants for
single sensor linear extrapolation equation. Because
the same sensor can be use in different locations,
from board to board, these constants are added
as part of thermal_zone_params.
The constants are available through sysfs.
It is up to the device driver to determine
the usage of these values.

The power allocator governor is a thermal governor that controls system
and device power allocation to control temperature. Conceptually, the
implementation divides the sustainable power of a thermal zone among
all the heat sources in that zone.
This governor relies on "power actors", entities that represent heat
sources. They can report current and maximum power consumption and
can set a given maximum power consumption, usually via a cooling
device.
The governor uses a Proportional Integral Derivative (PID) controller
driven by the temperature of the thermal zone. The output of the
controller is a power budget that is then allocated to each power
actor that can have bearing on the temperature we are trying to
control. It decides how much power to give each cooling device based
on the performance they are requesting. The PID controller ensures
that the total power budget does not exceed the control temperature.

The fair share governor has the concept of weights, which is the
influence of each cooling device in a thermal zone. The current
implementation forces the weights of all cooling devices in a thermal
zone to add up to a 100. This complicates setups, as you need to know
in advance how many cooling devices you are going to have. If you bind a
new cooling device, you have to modify all the other cooling devices
weights, which is error prone. Furthermore, you can't specify a
"default" weight for platforms since that default value depends on the
number of cooling devices in the platform.
This patch generalizes the concept of weight by allowing any number to
be a "weight". Weights are now relative to each other. Platforms that
don't specify weights get the same default value for all their cooling
devices, so all their cdevs are considered to be equally influential.
It's important to note that previous users of the weights don't need to
alter the code: percentages continue to work as they used to. This
patch just removes the constraint of all the weights in a thermal zone
having to add up to a 100. If they do, you get the same behavior as
before. If they don't, fair share now works for that platform.

Currently you can specify the weight of the cooling device in the device
tree but that information is not populated to the
thermal_bind_params where the fair share governor expects it to
be. The of thermal zone device doesn't have a thermal_bind_params
structure and arguably it's better to pass the weight inside the
thermal_instance as it is specific to the bind of a cooling device to a
thermal zone parameter.
Core thermal code is fixed to populate the weight in the instance from
the thermal_bind_params, so platform code that was passing the weight
inside the thermal_bind_params continue to work seamlessly.
While we are at it, create a default value for the weight parameter for
those thermal zones that currently don't define it and remove the
hardcoded default in of-thermal.

Commit 39d99cff76bf ("thermal: cpu_cooling: introduce
of_cpufreq_cooling_register") taught the cpu cooling device to register
devices that were linked to the device tree but didn't update the
cpu-cooling-api documentation. Fix it.

[ Upstream commit ee136af4a064c2f61e2025873584d2c7ec93f4ae ]
The usb-storage driver sets max_sectors = 240 in its scsi-host template,
for uas we do not want to do that for all devices, but testing has shown
that some devices need it.
This commit adds a US_FL_MAX_SECTORS_240 flag for such devices, and
implements support for it in uas.c, while at it it also adds support
for US_FL_MAX_SECTORS_64 to uas.c.

[ Upstream commit 94aa033efcac47b09db22cb561e135baf37b7887 ]
This fixes a bug introduced with commit c05c4186bbe4 ("KVM: s390:
add floating irq controller").
get_all_floating_irqs() does copy_to_user() while holding
a spin lock. Let's fix this by filling a temporary buffer
first and copy it to userspace after giving up the lock.

commit cf5d318865e25f887d49a0c6083bbc6dcd1905b1 upstream.
When a vcpu calls SYSTEM_OFF or SYSTEM_RESET with PSCI v0.2, the vcpus
should really be turned off for the VM adhering to the suggestions in
the PSCI spec, and it's the sane thing to do.
Also, clarify the behavior and expectations for exits to user space with
the KVM_EXIT_SYSTEM_EVENT case.

commit 3ad8b3de526a76fbe9466b366059e4958957b88f upstream.
The implementation of KVM_ARM_VCPU_INIT is currently not doing what
userspace expects, namely making sure that a vcpu which may have been
turned off using PSCI is returned to its initial state, which would be
powered on if userspace does not set the KVM_ARM_VCPU_POWER_OFF flag.
Implement the expected functionality and clarify the ABI.
