This adds basic support for delivering 2 level event channels to a guest.
Initially, it only supports delivery via the IRQ routing table, triggered
by an eventfd. In order to do so, it has a kvm_xen_set_evtchn_fast()
function which will use the pre-mapped shared_info page if it already
exists and is still valid, while the slow path through the irqfd_inject
workqueue will remap the shared_info page if necessary.
It sets the bits in the shared_info page but not the vcpu_info; that is
deferred to __kvm_xen_has_interrupt() which raises the vector to the
appropriate vCPU.
Add a 'verbose' mode to xen_shinfo_test while adding test cases for this.

Eric Dumazet suggested to allow users to modify max GRO packet size.
We have seen GRO being disabled by users of appliances (such as
wifi access points) because of claimed bufferbloat issues,
or some work arounds in sch_cake, to split GRO/GSO packets.
Instead of disabling GRO completely, one can chose to limit
the maximum packet size of GRO packets, depending on their
latency constraints.
This patch adds a per device gro_max_size attribute
that can be changed with ip link command.

ASoC: Updates for v5.17
Not much going on framework release this time, but a big update for
drivers especially the Intel and SOF ones.
- Refinements and cleanups around the delay() APIs.
- Wider use of dev_err_probe().
- Continuing cleanups and improvements to the SOF code.
- Support for pin switches in simple-card derived cards.
- Support for AMD Renoir ACP, Asahi Kasei Microdevices AKM4375, Intel

Currently, the CAN netlink interface provides no easy ways to check
the capabilities of a given controller. The only method from the
command line is to try each CAN_CTRLMODE_* individually to check
whether the netlink interface returns an -EOPNOTSUPP error or not
(alternatively, one may find it easier to directly check the source
code of the driver instead...)
This patch introduces a method for the user to check both the
supported and the static capabilities. The proposed method introduces
a new IFLA nest: IFLA_CAN_CTRLMODE_EXT which extends the current
IFLA_CAN_CTRLMODE. This is done to guaranty a full forward and
backward compatibility between the kernel and the user land
applications.
The IFLA_CAN_CTRLMODE_EXT nest contains one single entry:
IFLA_CAN_CTRLMODE_SUPPORTED. Because this entry is only used in one
direction: kernel to userland, no new struct nla_policy are
introduced.
Below table explains how IFLA_CAN_CTRLMODE_SUPPORTED (hereafter:
"supported") and can_ctrlmode::flags (hereafter: "flags") allow us to
identify both the supported and the static capabilities, when masked
with any of the CAN_CTRLMODE_* bit flags:
supported & flags & Controller capabilities
CAN_CTRLMODE_* CAN_CTRLMODE_*

Change the driver where WQ interrupt is requested only when wq is being
enabled. This new scheme set things up so that request_threaded_irq() is
only called when a kernel wq type is being enabled. This also sets up for
future interrupt request where different interrupt handler such as wq
occupancy interrupt can be setup instead of the wq completion interrupt.
Not calling request_irq() until the WQ actually needs an irq also prevents
wasting of CPU irq vectors on x86 systems, which is a limited resource.
idxd_flush_pending_descs() is moved to device.c since descriptor flushing
is now part of wq disable rather than shutdown().

When a mesh link is in blocked state, it is very useful to still allow
auth requests from the peer to re-establish it.
When a remote node is power cycled, the peer state can easily end up
in blocked state if multiple auth attempts are performed. Since this
can lead to several minutes of downtime, we should accept auth attempts
of the peer after it has come back.

This driver allows user space to fetch telemetry data from the
firmware with the help of the Platform Firmware Runtime Telemetry
interface.
Both PFRU and PFRT are based on ACPI _DSM interfaces located under
special device objects in the ACPI Namespace, but these interfaces
are different from each other, so it is better to provide a separate
driver from each of them, even though they share some common

Introduce the pfr_update driver which can be used for Platform Firmware
Runtime code injection and driver update [1].
The user is expected to provide the EFI capsule, and pass it to the
driver by writing the capsule to a device special file. The capsule
is transferred by the driver to the platform firmware with the help
of an ACPI _DSM method under the special ACPI Platform Firmware
Runtime Update device (INTC1080), and the actual firmware update is
carried out by the low-level Management Mode code in the platform
firmware.
This change allows certain pieces of the platform firmware to be
updated on the fly while the system is running (runtime) without the
need to restart it, which is key in the cases when the system needs to
be available 100% of the time and it cannot afford the downtime related
to restarting it, or when the work carried out by the system is
particularly important, so it cannot be interrupted, and it is not
practical to wait until it is complete.

Currently the cq counters are allocated in userspace memory,
and mapped by the driver to the device address space.
A new requirement that is part of new future API related to this one,
requires that cq counters will be allocated in kernel memory.
We leverage the existing cb_create API with KERNEL_MAPPED flag set to
allocate this memory.
That way we gain two things:
1. The memory cannot be freed while in use since it's protected
by refcount in driver.
2. No need to wake up the user thread upon each interrupt from CQ,
because the kernel has direct access to the counter. Therefore,
it can make comparison with the target value in the interrupt
handler and wake up the user thread only if the counter reaches the
target value. This is instead of waking the thread up to copy counter
value from user then go sleep again if target value wasn't reached.

event.

In order to increase maximum wait-for-interrupt timeout, change it
to 64 bit variable. This wait is used only by newer ASICs, so no
problem in changing this interface at this time.

Kernel generates mapping change message, XFRM_MSG_MAPPING,
when a source port chage is detected on a input state with UDP
encapsulation set. Kernel generates a message for each IPsec packet
with new source port. For a high speed flow per packet mapping change
message can be excessive, and can overload the user space listener.
Introduce rate limiting for XFRM_MSG_MAPPING message to the user space.
The rate limiting is configurable via netlink, when adding a new SA or
updating it. Use the new attribute XFRMA_MTIMER_THRESH in seconds.
v1->v2 change:
update xfrm_sa_len()
v2->v3 changes:
use u32 insted unsigned long to reduce size of struct xfrm_state
fix xfrm_ompat size Reported-by: kernel test robot <lkp@intel.com>
accept XFRM_MSG_MAPPING only when XFRMA_ENCAP is present

This macro is defined by glibc itself, which makes the issue go unnoticed on
those systems. On non-glibc systems it causes build failures on several

====================
This time we have:
* ndo_fill_forward_path support in mac80211, to let drivers use it
* association comeback notification for userspace, to be able
to react more sensibly to long delays
* support for background radar detection hardware in some chipsets
* SA Query Procedures offload on the AP side
* more logging if we find problems with HT/VHT/HE
* various cleanups and minor fixes

Add a flag attribute to use in ap settings to indicate userspace
supports offloading of SA Query procedures to driver. Also add AP SME
device feature flag to advertise that the SA Query procedures offloaded
to driver when userspace indicates support for offloading of SA Query
procedures.
Driver handles SA Query procedures in driver's SME it self and skip
sending SA Query request or response frames to userspace when userspace
indicates support for SA Query procedures offload. But if userspace
doesn't advertise support for SA Query procedures offload driver shall
not offload SA Query procedures handling.
Also userspace with SA Query procedures offload capability shall skip SA
Query specific validations when driver indicates support for handling SA
Query procedures.

In previous method each AP settings flag is represented by a top-level
flag attribute and conversion to enum cfg80211_ap_settings_flags had to
be done before sending them to driver. This commit is to make it easier
to define new AP settings flags and sending them to driver.
This commit also deprecate sending of
%NL80211_ATTR_EXTERNAL_AUTH_SUPPORT in %NL80211_CMD_START_AP. But to
maintain backwards compatibility checks for
%NL80211_ATTR_EXTERNAL_AUTH_SUPPORT in %NL80211_CMD_START_AP when
%NL80211_ATTR_AP_SETTINGS_FLAGS not present in %NL80211_CMD_START_AP.

ETSI standard defines "Offchannel CAC" as:
"Off-Channel CAC is performed by a number of non-continuous checks
spread over a period in time. This period, which is required to
determine the presence of radar signals, is defined as the Off-Channel
CAC Time..
Minimum Off-Channel CAC Time 6 minutes and Maximum Off-Channel CAC Time
4 hours..".
mac80211 implementation refers to a dedicated hw chain used for continuous
radar monitoring. Rename offchannel_* references to background_* in
order to avoid confusion with ETSI standard.
