[ Upstream commit e2f6ea61b6f3e4ebbb7dff857eea6220c18cd17b ]

The original .txt bindings had the OV2680 power supply names correct,
but the transition from .txt to yaml spelled them incorrectly.

Fix the OV2680 power supply names as the original .txt bindings
as these are the names used by the OV2680 driver and in devicetree.

[ Upstream commit c8c4353685778e75e186103411e9d01a4a3f2b90 ]

The temperature output register of the Loongson-2K2000 is defined in the
chip configuration domain, which is different from the Loongson-2K1000,
so it can't be fallbacked.

We need to use two groups of registers to describe it: the first group
is the high and low temperature threshold setting register; the second
group is the temperature output register.

It is true that this fix will cause ABI corruption, but it is necessary
otherwise the Loongson-2K2000 temperature sensor will not work properly.

commit 19fb11d7220b8abc016aa254dc7e6d9f2d49b178 upstream.

Add a required clock property as we can't access the device registers if
the AXI bus clock is not properly enabled.

Note this clock is a very fundamental one that is typically enabled
pretty early during boot. Independently of that, we should really rely on
it to be enabled.

Userspace had been unknowingly relying on a non-stable interface of
kernel internals to determine if partition scanning is enabled for a
given disk. Provide a stable interface for this purpose instead.

commit 14e70e4660d6ecaf503c461f072949ef8758e4a1 upstream.

To update effective size quota of DAMOS schemes on DAMON sysfs file
interface, user should write 'update_schemes_effective_quotas' to the
kdamond 'state' file.  But the document is mistakenly saying the input
string as 'update_schemes_effective_bytes'.  Fix it (s/bytes/quotas/).

commit da2a061888883e067e8e649d086df35c92c760a7 upstream.

The example usage of DAMOS filter sysfs files, specifically the part of
'matching' file writing for memcg type filter, is wrong.  The intention is
to exclude pages of a memcg that already getting enough care from a given
scheme, but the example is setting the filter to apply the scheme to only
the pages of the memcg.  Fix it.

commit d43ddd5c91802a46354fa4c4381416ef760676e2 upstream.

Running "make htmldocs" on a newly installed Sphinx 7.3.7 ends up in
a build error:

    Sphinx parallel build error:
    AttributeError: module 'docutils.nodes' has no attribute 'reprunicode'

docutils 0.21 has removed nodes.reprunicode, quote from release note [1]:

  * Removed objects:

    docutils.nodes.reprunicode, docutils.nodes.ensure_str()
        Python 2 compatibility hacks

Sphinx 7.3.0 supports docutils 0.21 [2]:

kernel_include.py, whose origin is misc.py of docutils, uses reprunicode.

Upstream docutils removed the offending line from the corresponding file
(docutils/docutils/parsers/rst/directives/misc.py) in January 2022.
Quoting the changelog [3]:

    Deprecate `nodes.reprunicode` and `nodes.ensure_str()`.

    Drop uses of the deprecated constructs (not required with Python 3).

Do the same for kernel_include.py.

Tested against:
  - Sphinx 2.4.5 (docutils 0.17.1)
  - Sphinx 3.4.3 (docutils 0.17.1)
  - Sphinx 5.3.0 (docutils 0.18.1)
  - Sphinx 6.2.1 (docutils 0.19)
  - Sphinx 7.2.6 (docutils 0.20.1)
  - Sphinx 7.3.7 (docutils 0.21.2)

docutils 0.21 has removed nodes.reprunicode, quote from release note [1]:

  * Removed objects:

    docutils.nodes.reprunicode, docutils.nodes.ensure_str()
        Python 2 compatibility hacks

Sphinx 7.3.0 supports docutils 0.21 [2]:

kernel_include.py, whose origin is misc.py of docutils, uses reprunicode.

Upstream docutils removed the offending line from the corresponding file
(docutils/docutils/parsers/rst/directives/misc.py) in January 2022.
Quoting the changelog [3]:

    Deprecate `nodes.reprunicode` and `nodes.ensure_str()`.

    Drop uses of the deprecated constructs (not required with Python 3).

Do the same for kernel_include.py.

Tested against:
  - Sphinx 2.4.5 (docutils 0.17.1)
  - Sphinx 3.4.3 (docutils 0.17.1)
  - Sphinx 5.3.0 (docutils 0.18.1)
  - Sphinx 6.2.1 (docutils 0.19)
  - Sphinx 7.2.6 (docutils 0.20.1)
  - Sphinx 7.3.7 (docutils 0.21.2)

commit 8af2d1ab78f2342f8c4c3740ca02d86f0ebfac5a upstream.

sched_core_share_pid() copies the cookie to userspace with
put_user(id, (u64 __user *)uaddr), expecting 64 bits of space.
The "unsigned long" datatype that is documented in core-scheduling.rst
however is only 32 bits large on 32 bit architectures.

Document "unsigned long long" as the correct data type that is always
64bits large.

This matches what the selftest cs_prctl_test.c has been doing all along.

Fixes: 0159bb020ca9 ("Documentation: Add usecases, design and interface for core scheduling")

Pull networking fixes from Paolo Abeni:
 "Including fixes from bluetooth and IPsec.

  The bridge patch is actually a follow-up to a recent fix in the same
  area. We have a pending v6.8 AF_UNIX regression; it should be solved
  soon, but not in time for this PR.

  Current release - regressions:

   - eth: ks8851: Queue RX packets in IRQ handler instead of disabling
     BHs

   - net: bridge: fix corrupted ethernet header on multicast-to-unicast

  Current release - new code bugs:

   - xfrm: fix possible bad pointer derferencing in error path

  Previous releases - regressionis:

   - core: fix out-of-bounds access in ops_init

   - ipv6:
      - fix potential uninit-value access in __ip6_make_skb()
      - fib6_rules: avoid possible NULL dereference in fib6_rule_action()

   - tcp: use refcount_inc_not_zero() in tcp_twsk_unique().

   - rtnetlink: correct nested IFLA_VF_VLAN_LIST attribute validation

   - rxrpc: fix congestion control algorithm

   - bluetooth:
      - l2cap: fix slab-use-after-free in l2cap_connect()
      - msft: fix slab-use-after-free in msft_do_close()

   - eth: hns3: fix kernel crash when devlink reload during
     initialization

   - eth: dsa: mv88e6xxx: add phylink_get_caps for the mv88e6320/21
     family

  Previous releases - always broken:

   - xfrm: preserve vlan tags for transport mode software GRO

   - tcp: defer shutdown(SEND_SHUTDOWN) for TCP_SYN_RECV sockets
