Pull drm fixes from Dave Airlie:
"Lots going on for rc2, ivpu has a bunch of stabilisation and debugging
work, then amdgpu and xe are the main fixes. i915, exynos have a few,
then some misc panel and bridge fixes.
Worth mentioning are three regressions. One of the nouveau fixes in
6.7 for a serious deadlock had side effects, so I guess we will bring
back the deadlock until I can figure out what should be done properly.
There was a scheduler regression vs amdgpu which was reported in a few
places and is now fixed. There was an i915 vs simpledrm problem
resulting in black screens, that is reverted also.
I'll be working on a proper nouveau fix, it kinda looks like one of
those cases where someone tried to use an atomic where they should
have probably used a lock, but I'll see.

The FORCE_STOP_STATE bit is unsuitable to force the DSI link into LP-11
mode. It seems the bridge internally queues DSI packets and when the
FORCE_STOP_STATE bit is cleared, they are sent in close succession
without any useful timing (this also means that the DSI lanes won't go
into LP-11 mode). The length of this gibberish varies between 1ms and
5ms. This sometimes breaks an attached bridge (TI SN65DSI84 in this
case). In our case, the bridge will fail in about 1 per 500 reboots.
The FORCE_STOP_STATE handling was introduced to have the DSI lanes in
LP-11 state during the .pre_enable phase. But as it turns out, none of
this is needed at all. Between samsung_dsim_init() and
samsung_dsim_set_display_enable() the lanes are already in LP-11 mode.
The code as it was before commit 20c827683de0 ("drm: bridge:
samsung-dsim: Fix init during host transfer") and 0c14d3130654 ("drm:
bridge: samsung-dsim: Fix i.MX8M enable flow to meet spec") was correct
in this regard.
This patch basically reverts both commits. It was tested on an i.MX8M
SoC with an SN65DSI84 bridge. The signals were probed and the DSI
packets were decoded during initialization and link start-up. After this
patch the first DSI packet on the link is a VSYNC packet and the timing
is correct.
Command mode between .pre_enable and .enable was also briefly tested by
a quick hack. There was no DSI link partner which would have responded,
but it was made sure the DSI packet was send on the link. As a side
note, the command mode seems to just work in HS mode. I couldn't find
that the bridge will handle commands in LP mode.
Fixes: 20c827683de0 ("drm: bridge: samsung-dsim: Fix init during host transfer")

Pull networking fixes from Paolo Abeni:
"Including fixes from bpf, netfilter and WiFi.
Jakub is doing a lot of work to include the self-tests in our CI, as a
result a significant amount of self-tests related fixes is flowing in
(and will likely continue in the next few weeks).
Current release - regressions:
- bpf: fix a kernel crash for the riscv 64 JIT
- bnxt_en: fix memory leak in bnxt_hwrm_get_rings()
- revert "net: macsec: use skb_ensure_writable_head_tail to expand
the skb"
Previous releases - regressions:
- core: fix removing a namespace with conflicting altnames
- tc/flower: fix chain template offload memory leak
- tcp:
- make sure init the accept_queue's spinlocks once
- fix autocork on CPUs with weak memory model
- udp: fix busy polling
- mlx5e:
- fix out-of-bound read in port timestamping
- fix peer flow lists corruption
- iwlwifi: fix a memory corruption
Previous releases - always broken:
- netfilter:
- nft_chain_filter: handle NETDEV_UNREGISTER for inet/ingress
basechain
- nft_limit: reject configurations that cause integer overflow
- bpf: fix bpf_xdp_adjust_tail() with XSK zero-copy mbuf, avoiding a
NULL pointer dereference upon shrinking
- llc: make llc_ui_sendmsg() more robust against bonding changes
- smc: fix illegal rmb_desc access in SMC-D connection dump
- dpll: fix pin dump crash for rebound module
- bnxt_en: fix possible crash after creating sw mqprio TCs
- hv_netvsc: calculate correct ring size when PAGE_SIZE is not 4kB
Misc:
- several self-tests fixes for better integration with the netdev CI
- added several missing modules descriptions"

This commit fixes RCU grace period stalls, which are observed when
an outgoing CPU's quiescent state reporting results in wakeup of
one of the grace period kthreads, to complete the grace period. If
those kthreads have SCHED_FIFO policy, the wake up can indirectly
arm the RT bandwith timer to the local offline CPU. Earlier migration
of the hrtimers from the CPU introduced in commit 5c0930ccaad5
("hrtimers: Push pending hrtimers away from outgoing CPU earlier")
results in this timer getting ignored. If the RCU grace period
kthreads are waiting for RT bandwidth to be available, they may
never be actually scheduled, resulting in RCU stall warnings.

use of xa_insert instead of xa_store to flag case of duplicate insertion.
It also simplifies ffa_partitions_cleanup() with xa_for_each() and xa_erase()
instead of xa_extract() and kfree(). Finally it includes fixes around

1. A spurious IRQ related to the late reply can get wrongly associated
with the new enqueued request resulting in misinterpretation of data
in shared memory. This race-condition can be detected by looking at
the channel status bits which the platform must set to the channel
free before triggering the completion IRQ. Adding a consistency check
to validate such condition will fix the issue.

Since commit 26c9d152ebf3 ("dt-bindings: tpm: Consolidate TCG TIS
bindings"), several issues are reported by "make dtbs_check" for arm64
devicetrees:
The compatible property needs to contain the chip's name in addition to
the generic "tcg,tpm_tis-spi" and the nodename needs to be "tpm@0"
rather than "cr50@0":
tpm@1: compatible: ['tcg,tpm_tis-spi'] is too short
from schema $id: http://devicetree.org/schemas/tpm/tcg,tpm_tis-spi.yaml#
cr50@0: $nodename:0: 'cr50@0' does not match '^tpm(@[0-9a-f]+)?$'
from schema $id: http://devicetree.org/schemas/tpm/google,cr50.yaml#
Fix these schema violations.
