It is possible that remote processor is already running before
linux boot or remoteproc platform driver probe. Implement required
remoteproc framework ops to provide resource table address and
connect or disconnect with remote processor in such case.

Duplicate FB_BLANK_ constants as BACKLIGHT_POWER__ constants in the
backlight header file. Allows backlight drivers to avoid including
the fbdev header file and removes a compile-time dependency between
the two subsystems.
The new BACKLIGHT_POWER_ constants have the same values as their
FB_BLANK_ counterparts. Hence UAPI and internal semantics do not
change. The backlight drivers can be converted one by one. Each
instance of FB_BLANK_UNBLANK becomes BACKLIGHT_POWER_ON, each of
FB_BLANK_POWERDOWN becomes BACKLIGHT_POWER_OFF, and FB_BLANK_NORMAL
becomes BACKLIGHT_POWER_REDUCED.
Backlight code or drivers do not use FB_BLANK_VSYNC_SUSPEND and
FB_BLANK_HSYNC_SUSPEND, so no new constants for these are being
added.
The semantics of FB_BLANK_NORMAL appear inconsistent. In fbdev,
NORMAL means display off with sync enabled. In backlight code,
this translates to turn the backlight off, but some drivers
interpret it as backlight on. So we keep the current code as is,
but mark BACKLIGHT_POWER_REDUCED as deprecated. Drivers should be
fixed and the constant removed. This affects ams369fg06 and a few
DRM panel drivers.
v2:
- rename BL_CORE_ power constants to BACKLIGHT_POWER_ (Sam)
- fix documentation

For varying privacy and security reasons, sometimes we would like to
completely silence the _serial_ console, and only enable it when needed.
But there are many existing systems that depend on this _serial_ console,
so add acpi=nospcr to disable console in ACPI SPCR table as default
_serial_ console.

Two missing check in virtio_net_hdr_to_skb() allowed syzbot
to crash kernels again
1. After the skb_segment function the buffer may become non-linear
(nr_frags != 0), but since the SKBTX_SHARED_FRAG flag is not set anywhere
the __skb_linearize function will not be executed, then the buffer will
remain non-linear. Then the condition (offset >= skb_headlen(skb))
becomes true, which causes WARN_ON_ONCE in skb_checksum_help.
2. The struct sk_buff and struct virtio_net_hdr members must be
mathematically related.
(gso_size) must be greater than (needed) otherwise WARN_ON_ONCE.
(remainder) must be greater than (needed) otherwise WARN_ON_ONCE.
(remainder) may be 0 if division is without remainder.

There are two issues around seqpacket_allow:
1. seqpacket_allow is not initialized when socket is
created. Thus if features are never set, it will be
read uninitialized.
2. if VIRTIO_VSOCK_F_SEQPACKET is set and then cleared,
then seqpacket_allow will not be cleared appropriately
(existing apps I know about don't usually do this but
it's legal and there's no way to be sure no one relies
on this).
To fix:
- initialize seqpacket_allow after allocation
- set it unconditionally in set_features

Add a way for firmware to tell the OS that ATS is supported by the PCI
root complex. An endpoint with ATS enabled may send Translation Requests
and Translated Memory Requests, which look just like Normal Memory
Requests with a non-zero AT field. So a root controller that ignores the
AT field may simply forward the request to the IOMMU as a Normal Memory
Request, which could end badly. In any case, the endpoint will be
unusable.
The ats-supported property allows the OS to only enable ATS in endpoints
if the root controller can handle ATS requests. Only add the property to
pcie-host-ecam-generic for the moment. For non-generic root controllers,
availability of ATS can be inferred from the compatible string.

As like the 'epc_init' event, that is used to signal the EPF drivers about
the EPC initialization, let's introduce 'epc_deinit' event that is used to
signal EPC deinitialization.
The EPC deinitialization applies only when any sort of fundamental reset
is supported by the endpoint controller as per the PCIe spec.
Reference: PCIe r6.0, sec 4.2.5.9.1 and 6.6.1.
Currently, some EPC drivers like pcie-qcom-ep and pcie-tegra194 support
PERST# as the fundamental reset. So the 'deinit' event will be notified to
the EPF drivers when PERST# assert happens in the above mentioned EPC
drivers.
The EPF drivers, on receiving the event through the epc_deinit() callback
should reset the EPF state machine and also cleanup any configuration that
got affected by the fundamental reset like BAR, DMA etc...
This change also warrants skipping the cleanups in unbind() if already done
in epc_deinit().

While creating a new RSS context, bnxt_rfs_capable() currently
makes a strict check to see if the required VNICs are already
available. If the current VNICs are not what is required,
either too many or not enough, it will call the firmware to
reserve the exact number required.
There is a bug in the firmware when the driver tries to
relinquish some reserved VNICs and RSS contexts. It will
cause the default VNIC to lose its RSS configuration and
cause receive packets to be placed incorrectly.
Workaround this problem by skipping the resource reduction.
The driver will not reduce the VNIC and RSS context reservations
when a context is deleted. The resources will be available for
use when new contexts are created later.
Potentially, this workaround can cause us to run out of VNIC
and RSS contexts if there are a lot of VF functions creating
and deleting RSS contexts. In the future, we will conditionally
disable this workaround when the firmware fix is available.

In case of invalid INI file mlxsw_linecard_types_init() deallocates memory
but doesn't reset pointer to NULL and returns 0. In case of any error
occurred after mlxsw_linecard_types_init() call, mlxsw_linecards_init()
calls mlxsw_linecard_types_fini() which performs memory deallocation again.
Add pointer reset to NULL.
Found by Linux Verification Center (linuxtesting.org) with SVACE.

Few fixes also to mac80211 and iwlwifi.
* tag 'wireless-2024-07-04' of git://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless:
wifi: iwlwifi: mvm: check vif for NULL/ERR_PTR before dereference
wifi: iwlwifi: mvm: avoid link lookup in statistics
wifi: iwlwifi: mvm: don't wake up rx_sync_waitq upon RFKILL
wifi: iwlwifi: properly set WIPHY_FLAG_SUPPORTS_EXT_KEK_KCK

Move allocation tagging specific code in the allocation path into
alloc_tagging_slab_alloc_hook, similar to how freeing path uses
alloc_tagging_slab_free_hook. No functional changes, just code
cleanup.
