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 20c82768 ("drm: bridge:
samsung-dsim: Fix init during host transfer") and 0c14d313 ("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.

All entities must be drained in the DRM scheduler run job worker to
avoid the following case. An entity found that is ready, no job found
ready on entity, and run job worker goes idle with other entities + jobs
ready. Draining all ready entities (i.e. loop over all ready entities)
in the run job worker ensures all job that are ready will be scheduled.

   - 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"

Pull overlayfs fix from Amir Goldstein:
 "Change the on-disk format for the new "xwhiteouts" feature introduced
  in v6.7

  The change reduces unneeded overhead of an extra getxattr per readdir.
  The only user of the "xwhiteout" feature is the external composefs
  tool, which has been updated to support the new on-disk format.

  This change is also designated for 6.7.y"
