Pull netfx fixes from David Howells:
"Two fixes, affecting the functions that iterates over the pagecache
unmarking or unlocking pages after an op is complete:
- xas_for_each() loops must call xas_retry() first thing and
immediately do a "continue" in the case that the extracted value is
a special value that indicates that the walk raced with a
modification. Fix the unlock and unmark loops to do this.
- The maths in the unlock loop is dodgy as it could, theoretically,
at some point in the future end up with a starting file pointer
that is in the middle of a folio. This will cause a subtraction to
go negative - but the number is unsigned. Fix the maths to use
absolute file positions instead of relative page indices"

Current dual mode adaptor ("DP++") detection code assumes that all
adaptors support i2c sub-addressing for read operations from the
DP-HDMI adaptor ID buffer. It has been observed that multiple
adaptors do not in fact support this, and always return data starting
at register 0. On affected adaptors, the code fails to read the proper
registers that would identify the device as a type 2 adaptor, and
handles those as type 1, limiting the TMDS clock to 165MHz, even if
the according register would announce a higher TMDS clock.
Fix this by always reading the ID buffer starting from offset 0, and
discarding any bytes before the actual offset of interest.
We tried finding authoritative documentation on whether or not this is
allowed behaviour, but since all the official VESA docs are paywalled,
the best we could come up with was the spec sheet for Texas Instruments'
SNx5DP149 chip family.[1] It explicitly mentions that sub-addressing is
supported for register writes, but *not* for reads (See NOTE in
section 8.5.3). Unless TI openly decided to violate the VESA spec, one
could take that as a hint that sub-addressing is in fact not mandated
by VESA.
The other two adaptors affected used the PS8409(A) and the LT8611,
according to the data returned from their ID buffers.

Currently, we check any received packet whether we have already seen it
previously, regardless of the packet type (sequenced / unsequenced). We
do this by checking the sequence number. This assumes that sequence
numbers are valid for both sequenced and unsequenced packets. However,
this assumption appears to be incorrect.
On some devices, the sequence number field of unsequenced packets (in
particular HID input events on the Surface Pro 9) is always zero. As a
result, the current retransmission check kicks in and discards all but
the first unsequenced packet, breaking (among other things) keyboard and
touchpad input.
Note that we have, so far, only seen packets being retransmitted in
sequenced communication. In particular, this happens when there is an
ACK timeout, causing the EC (or us) to re-send the packet waiting for an
ACK. Arguably, retransmission / duplication of unsequenced packets
should not be an issue as there is no logical condition (such as an ACK
timeout) to determine when a packet should be sent again.
Therefore, remove the retransmission check for unsequenced packets
entirely to resolve the issue.

The current logic in the Intel PMC driver will forcefully attach it
when detecting any CPU on the intel_pmc_core_platform_ids array,
even if the matching ACPI device is not present.
There's no checking in pmc_core_probe() to assert that the PMC device
is present, and hence on virtualized environments the PMC device
probes successfully, even if the underlying registers are not present.
Before commit 21ae435709 ("platform/x86: intel_pmc_core: Substitute PCI
with CPUID enumeration") the driver would check for the presence of a
specific PCI device, and that prevented the driver from attaching when
running virtualized.
Fix by only forcefully attaching the PMC device when not running
virtualized. Note that virtualized platforms can still get the device
to load if the appropriate ACPI device is present on the tables
provided to the VM.
Make an exception for the Xen initial domain, which does have full
hardware access, and hence can attach to the PMC if present.

Previously, the s2idle quirk was only active for the 21A0 machine type
of the P14s Gen2a product. This also enables it for the second 21A1 type,
thus reducing wake-up times from s2idle.

These drivers work on our other FPGAs, for example the non-SoC PolarFire
connected to an FU-540 via chiplink. Make the entry a wee bit more
generic to match. While at it, remove the / from the heading so that it
matches other, neighbouring RISC-V entries.

Following some discussion both on & off list, I have volunteered to take
over maintaining the miscellaneous RISC-V devicetrees & soc drivers from
Palmer to ease his load.
So far only SiFive and Microchip have stuff in drivers/soc. For the
former, a SiFive entry exists with a dead GitHub repo - so remove that
to avoid confusion since the patches for drivers/soc & devicetrees will
be routed via my tree & other drivers go through their subsystem trees.
The Microchip directory only contains a RISC-V driver for now, but is
likely to contain drivers for other archs in the future. To that end,
change the PolarFire SoC entry to specifically mention the RISC-V driver
& the new directory level entry does not mention an architecture.

The bridge driver can offload VLANs to the underlying hardware either
via switchdev or the 8021q driver. When the former is used, the VLAN is
marked in the bridge driver with the 'BR_VLFLAG_ADDED_BY_SWITCHDEV'
private flag.
To avoid the memory leaks mentioned in the cited commit, the bridge
driver will try to delete a VLAN via the 8021q driver if the VLAN is not
marked with the previously mentioned flag.
When the VLAN protocol of the bridge changes, switchdev drivers are
notified via the 'SWITCHDEV_ATTR_ID_BRIDGE_VLAN_PROTOCOL' attribute, but
the 8021q driver is also called to add the existing VLANs with the new
protocol and delete them with the old protocol.
In case the VLANs were offloaded via switchdev, the above behavior is
both redundant and buggy. Redundant because the VLANs are already
programmed in hardware and drivers that support VLAN protocol change
(currently only mlx5) change the protocol upon the switchdev attribute
notification. Buggy because the 8021q driver is called despite these
VLANs being marked with 'BR_VLFLAG_ADDED_BY_SWITCHDEV'. This leads to
memory leaks [1] when the VLANs are deleted.
Fix by not calling the 8021q driver for VLANs that were already
programmed via switchdev.

Currently, if driver is in phy-imp(phy controlled by imp firmware) mode, as
driver did not update phy link ksettings after initialization process or
not update advertising when getting phy link ksettings from firmware, it
may set incorrect phy link ksettings for firmware in resetting process.

sk->sk_receive_queue is protected by skb queue lock, but for KCM
sockets its RX path takes mux->rx_lock to protect more than just
skb queue. However, kcm_recvmsg() still only grabs the skb queue
lock, so race conditions still exist.
We can teach kcm_recvmsg() to grab mux->rx_lock too but this would
introduce a potential performance regression as struct kcm_mux can
be shared by multiple KCM sockets.
So we have to enforce skb queue lock in requeue_rx_msgs() and handle
skb peek case carefully in kcm_wait_data(). Fortunately,
skb_recv_datagram() already handles it nicely and is widely used by
other sockets, we can just switch to skb_recv_datagram() after
getting rid of the unnecessary sock lock in kcm_recvmsg() and
kcm_splice_read(). Side note: SOCK_DONE is not used by KCM sockets,
so it is safe to get rid of this check too.
