b72eb8435b usb: xhci: Fix USB 3.1 supported protocol parsing
xHCI host controllers can have both USB 3.1 and 3.0 extended speed
protocol lists. If the USB3.1 speed is parsed first and 3.0 second then
the minor revision supported will be overwritten by the 3.0 speeds and
the USB3 roothub will only show support for USB 3.0 speeds.

This was the case with a xhci controller with the supported protocol
capability listed below.
In xhci-mem.c, the USB 3.1 speed is parsed first, the min_rev of usb3_rhub
is set as 0x10.  And then USB 3.0 is parsed.  However, the min_rev of
usb3_rhub will be changed to 0x00. If USB 3.1 device is connected behind
this host controller, the speed of USB 3.1 device just reports 5G speed
using lsusb.

073cf9e20c Merge branch 'udp-reduce-cache-pressure'
Paolo Abeni says:

====================
udp: reduce cache pressure

In the most common use case, many skb fields are not used by recvmsg(), and
the few ones actually accessed lays on cold cachelines, which leads to several
cache miss per packet.

This patch series attempts to reduce such misses with different strategies:
* caching the interesting fields in the scratched space
* avoid accessing at all uninteresting fields
* prefetching

Tested using the udp_sink program by Jesper[1] as the receiver, an h/w l4 rx
hash on the ingress nic, so that the number of ingress nic rx queues hit by the
udp traffic could be controlled via ethtool -L.

The udp_sink program was bound to the first idle cpu, to get more
stable numbers.

On a single numa node receiver:

b65ac44674 udp: try to avoid 2 cache miss on dequeue
when udp_recvmsg() is executed, on x86_64 and other archs, most skb
fields are on cold cachelines.
If the skb are linear and the kernel don't need to compute the udp
csum, only a handful of skb fields are required by udp_recvmsg().
Since we already use skb->dev_scratch to cache hot data, and
there are 32 bits unused on 64 bit archs, use such field to cache
as much data as we can, and try to prefetch on dequeue the relevant
fields that are left out.

This can save up to 2 cache miss per packet.

v1 -> v2:
  - changed udp_dev_scratch fields types to u{32,16} variant,
    replaced bitfiled with bool

0a463c78d2 udp: avoid a cache miss on dequeue
Since UDP no more uses sk->destructor, we can clear completely
the skb head state before enqueuing. Amend and use
skb_release_head_state() for that.

All head states share a single cacheline, which is not
normally used/accesses on dequeue. We can avoid entirely accessing
such cacheline implementing and using in the UDP code a specialized
skb free helper which ignores the skb head state.

This saves a cacheline miss at skb deallocation time.

v1 -> v2:
  replaced secpath_reset() with skb_release_head_state()

ACPICA commit ed0389cb11a61e63c568ac1f67948fc6a7bd1aeb

An invalid opcode indicates something seriously wrong with the
input AML file. The AML parser is immediately confused and lost,
causing the resulting parse tree to be ill-formed. The actual
disassembly can then cause numerous unrelated errors and faults.

This change aborts the disassembly upon discovery of such an
opcode during the AML parse phase.

cf45b58cd1 ACPICA: Core: Always set GPIO VendorOffset
ACPICA commit 51a92f414de7af1f7f7524de3f61daf5413cac9f

Acpiexec gives this warning when resources containing GPIOs are extracted
using Resource command:

  **** Data mismatch in descriptor [00] type 8C, Offset 00000000 ****
  Mismatch at byte offset 13: is 00, should be 25
  **** Data mismatch in descriptor [01] type 8C, Offset 00000025 ****
  Mismatch at byte offset 13: is 00, should be 25

This happens because we do not set VendorOffset when doing resource to AML
conversion. Fix this by always setting VendorOffset.

ACPICA commit 08b83591c0db751769d61fa889f4f50f575aeffb

PinGroupConfig() is analogous to PinGroupFunction() but instead of mode
(muxing), it is used to apply specific fine-grained configuration to a
set of referenced pins.

The format of this new resource is:

  PinGroupConfig (Shared/Exclusive, PinConfigType, PinConfigValue,
                  ResourceSource, ResourceSourceIndex, ResourceSourceLabel,
                  ResourceUsage, DescriptorName, VendorData)

The PinConfigType/PinConfigValue are the same used by PinConfig()
resource.

Here also the combination of ResourceSource and ResourceSourceLabel is
used to specify the PinGroup() this resource refers to.

f8a6c86644 ACPICA: ACPI 6.2: Add support for PinGroupFunction() resource
ACPICA commit bd9a745749eac7137cd23085e6bdeb322de14ea2

PinGroupFunction() is a new resource introduced with ACPI 6.2. It is
used with PinGroup() to configure specific mode for a set of pins
exposed by a GPIO controller.

The format of the resource is:

  PinGroupFunction (Shared/Exclusive, FunctionNumber, ResourceSource,
                    ResourceSourceIndex, ResourceSourceLabel,
                    ResourceUsage, DescriptorName, VendorData)

The resource_source and ResourceSourceLabel fields are used to specify
the PinGroup() resource referenced by PinGroupFunction().

  Device (GPIO)
  {
      Name (_CRS, ResourceTemplate () {
          PinGroup ("group1") {2, 3}
          PinGroup ("group2") {4, 5}
          ...
      })
  }

  Device (I2C)
  {
      Name (_CRS, ResourceTemplate () {
          PinGroupFunction (Exclusive, 6, "^GPIO", 0, "mygroup2")
      })
  }

In the above example the PinGroupFunction() references the second
PinGroup() resource (using label "mygroup2" and configures pins 4 and 5
into mode 6.

fdaa098077 ACPICA: ACPI 6.2: Add support for PinGroup() resource
ACPICA commit 7d928e3174fb19d7dc0066b03c30bea07c001563

ACPI 6.2 introduced a new resource that is used to declare set of pins
belonging to a GPIO controller. This resource is referenced by new
PinGroupFunction() and PinGroupConfig() resources using ResourceSource
and ResourceLabel fields.

The PinGroup() resource looks like this:

  PinGroup (ResourceLabel, ResourceUsage, DescriptorName,
            VendorData) {Pin List}

This resource should be listed in _CRS under the GPIO/pincontroller
device providing these pins.

97028ce6fc ACPICA: ACPI 6.2: Add support for PinConfig() resource
ACPICA commit a06fdba686cefccd5dd5b93b52fa0f1e3f984906

ACPI 6.2 introduced a new resource that is used to specify fine-grained
configuration of a pin or set of pins used by a device. The ASL syntax of
this new resource looks like:

  PinConfig (Shared/Exclusive, PinConfigType, PinConfigValue,
             ResourceSource, ResourceSourceIndex, ResourceUsage,
             DescriptorName, Vendordata) {Pin List}

PinConfigType is an integer with following accepted values:

  0x00 (Default) - No configuration is applied to the pin
  0x01 (Bias Pull-up) - Pin is pulled up using certain size resistor
  0x02 (Bias Pull-down) - Pin is pulled down using certain size resistor
  0x03 (Bias Default) - Set to default biasing
  0x04 (Bias Disable) - All bias settings will be disabled
  0x05 (Bias High Impedance) - Configure the pin as hi_z
  0x06 (Bias Bus Hold) - Configure the pin in a weak latch state where
                         it drives the last value on a tristate bus
  0x07 (Drive Open Drain) - Configure the pin into open drain state
  0x08 (Drive Open Source) - Configure the pin into open source state
  0x09 (Drive Push Pull) - Configure the pin into push-pull state
  0x0a (Drive Strength) - How much the pin can supply current
  0x0b (Slew Rate) - Configure slew rate of the pin
  0x0c (Input Debounce) - Enable input debouncer for the pin
  0x0d (Input Schmitt Trigger) - Enable schmitt trigger for the pin
  0x0e - 0x7f - Reserved
  0x80 - 0xff - Vendor defined types

The PinConfigValue depends on the type and is expressed as units
suitable for that type (for example bias uses Ohms).

ACPICA commit 6bbc6357f7061f1243601adde0ea45f7a89274e0

ACPI 6.2 introduced a new resource that is used to describe how certain
pins are muxed for a device. The ASL syntax of this new resource looks
like below:

  PinFunction(Shared, PinConfig, FunctionNumber, ResourceSource,
              ResourceSourceIndex, ResourceUsage, DescriptorName,
              VendorData) {Pin List}

Which is pretty similar to GpioIo()/GpioInt() resources.

Teach ACPICA about this new resource.

Move Switch code to new dmswitch.c file. Also improves algorithm to
handle multiple levels of Switch statements and perform legacy

Commit 27ed3cd2eb (cpufreq: conservative: Fix the logic in frequency
decrease checking) removed the 10 point substraction when comparing the
load against down_threshold but did not remove the related limit for the
down_threshold value.  As a result, down_threshold lower than 11 is not
allowed even though values from 1 to 10 do work correctly too. The
comment ("cannot be lower than 11 otherwise freq will not fall") also
does not apply after removing the substraction.

For this reason, allow down_threshold to take any value from 1 to 99
and fix the related comment.
