Pull spi fixes from Mark Brown:
"A few bigger things here, the main one being that there were changes
to the atmel driver in this cycle which made it possible to kill
transfers being used for filesystem I/O which turned out to be very
disruptive, the series of patches here undoes that and hardens things
up further.
There's also a few smaller driver specific changes, the main one being
to revert a change that duplicted delays"

__bio_for_each_segment assumes that the first struct bio_vec argument
doesn't change - it calls "bio_advance_iter_single((bio), &(iter),
(bvl).bv_len)" to advance the iterator. Unfortunately, the dm-integrity
code changes the bio_vec with "bv.bv_len -= pos". When this code path
is taken, the iterator would be out of sync and dm-integrity would
report errors. This happens if the machine is out of memory and
"kmalloc" fails.
Fix this bug by making a copy of "bv" and changing the copy instead.

After commit db5e653d7c9f ("md: delay choosing sync action to
md_start_sync()"), md_start_sync() will hold 'reconfig_mutex', however,
in order to make sure event_work is done, __md_stop() will flush
workqueue with reconfig_mutex grabbed, hence if sync_work is still
pending, deadlock will be triggered.
Fortunately, former pacthes to fix stopping sync_thread already make sure
all sync_work is done already, hence such deadlock is not possible
anymore. However, in order not to cause confusions for people by this
implicit dependency, delay flushing event_work to dm-raid where
'reconfig_mutex' is not held, and add some comments to emphasize that
the workqueue can't be flushed with 'reconfig_mutex'.

Currently the __uprobe_register will return 0 (success) when called with
negative offset. The reason is that the call to register_for_each_vma and
then build_map_info won't return error for negative offset. They just won't
do anything - no matching vma is found so there's no registered breakpoint
for the uprobe.
I don't think we can change the behaviour of __uprobe_register and fail
for negative uprobe offset, because apps might depend on that already.
But I think we can still make the change and check for it on bpf multi
link syscall level.
Also moving the __get_user call and check for the offsets to the top of
loop, to fail early without extra __get_user calls for ref_ctr_offset
and cookie arrays.

Commit 6624e780a577fc596788 ("ice: split ice_vsi_setup into smaller
functions") has refactored a bunch of code involved in PFR. In this
process, TC queue number adjustment for XDP was lost. Bring it back.
Lack of such adjustment causes interface to go into no-carrier after a
reset, if XDP program is attached, with the following message:
ice 0000:b1:00.0: Failed to set LAN Tx queue context, error: -22
ice 0000:b1:00.0 ens801f0np0: Failed to open VSI 0x0006 on switch 0x0001

Previously, the ice driver had support for using a handler for bonding
netdev events to ensure that conflicting features were not allowed to be
activated at the same time. While this was still in place, additional
support was added to specifically support SRIOV and LAG together. These
both utilized the netdev event handler, but the SRIOV and LAG feature was
behind a capabilities feature check to make sure the current NVM has
support.
The exclusion part of the event handler should be removed since there are
users who have custom made solutions that depend on the non-exclusion of
features.
Wrap the creation/registration and cleanup of the event handler and
associated structs in the probe flow with a feature check so that the
only systems that support the full implementation of LAG features will
initialize support. This will leave other systems unhindered with
functionality as it existed before any LAG code was added.

When there is bpf_list_head or bpf_rb_root field in map value, the free
of map btf and the free of map value may run concurrently and there may
be use-after-free problem, so add two test cases to demonstrate it. And
the use-after-free problem can been easily reproduced by using bpf_next
tree and a KASAN-enabled kernel.
The first test case tests the racing between the free of map btf and the
free of array map. It constructs the racing by releasing the array map in
the end after other ref-counter of map btf has been released. To delay
the free of array map and make it be invoked after btf_free_rcu() is
invoked, it stresses system_unbound_wq by closing multiple percpu array
maps before it closes the array map.
The second case tests the racing between the free of map btf and the
free of inner map. Beside using the similar method as the first one
does, it uses bpf_map_delete_elem() to delete the inner map and to defer
the release of inner map after one RCU grace period.
The reason for using two skeletons is to prevent the release of outer
map and inner map in map_in_map_btf.c interfering the release of bpf
map in normal_map_btf.c.

When creating new VSIs, they are assigned into an aggregator node in the
scheduler tree. Information about which aggregator node a VSI is assigned
into is maintained by the vsi->agg_node structure. In ice_vsi_decfg(), this
information is being destroyed, by overwriting the valid flag and the
agg_id field to zero.
For VF VSIs, this breaks the aggregator node configuration replay, which
depends on this information. This results in VFs being inserted into the
default aggregator node. The resulting configuration will have unexpected
Tx bandwidth sharing behavior.
This was broken by commit 6624e780a577 ("ice: split ice_vsi_setup into
smaller functions"), which added the block to reset the agg_node data.
The vsi->agg_node structure is not managed by the scheduler code, but is
instead a wrapper around an aggregator node ID that is tracked at the VSI
layer. Its been around for a long time, and its primary purpose was for
handling VFs. The SR-IOV VF reset flow does not make use of the standard VSI
rebuild/replay logic, and uses vsi->agg_node as part of its handling to
rebuild the aggregator node configuration.
The logic for aggregator nodes stretches back to early ice driver code from
commit b126bd6bcd67 ("ice: create scheduler aggregator node config and move
VSIs")
The logic in ice_vsi_decfg() which trashes the ice_agg_node data is clearly
wrong. It destroys information that is necessary for handling VF reset,. It
is also not the correct way to actually remove a VSI from an aggregator
node. For that, we need to implement logic in the scheduler code. Further,
non-VF VSIs properly replay their aggregator configuration using existing
scheduler replay logic.
To fix the VF replay logic, remove this broken aggregator node cleanup
logic. This is the simplest way to immediately fix this.
This ensures that VFs will have proper aggregate configuration after a
reset. This is especially important since VFs often perform resets as part
of their reconfiguration flows. Without fixing this, VFs will be placed in
the default aggregator node and Tx bandwidth will not be shared in the
expected and configured manner.

There's nothing wrong with this commit, but this is dead code now

For some reason, the wait_on_bit() in nfsd4_deleg_getattr_conflict()
is waiting forever, preventing a clean server shutdown. The
requesting client might also hang waiting for a reply to the
conflicting GETATTR.
Invoking wait_on_bit() in an nfsd thread context is a hazard. The
correct fix is to replace this wait_on_bit() call site with a
mechanism that defers the conflicting GETATTR until the CB_GETATTR
completes or is known to have failed.
That will require some surgery and extended testing and it's late
in the v6.7-rc cycle, so I'm reverting now in favor of trying again
in a subsequent kernel release.
This is my fault: I should have recognized the ramifications of
calling wait_on_bit() in here before accepting this patch.
Thanks to Dai Ngo <dai.ngo@oracle.com> for diagnosing the issue.

The Laptop 13 (AMD Ryzen 7040Series) BIOS 03.03 has a workaround
included in the EC firmware that will cause the EC to emit a "spurious"
keypress during the resume from s0i3 [1].
This series of keypress events can be observed in the kernel log on
resume.
```
atkbd serio0: Unknown key pressed (translated set 2, code 0x6b on isa0060/serio0).
atkbd serio0: Use 'setkeycodes 6b <keycode>' to make it known.
atkbd serio0: Unknown key released (translated set 2, code 0x6b on isa0060/serio0).
atkbd serio0: Use 'setkeycodes 6b <keycode>' to make it known.
```
In some user flows this is harmless, but if a user has specifically
suspended the laptop and then closed the lid it will cause the laptop
to wakeup. The laptop wakes up because the ACPI SCI triggers when
the lid is closed and when the kernel sees that IRQ1 is "also" active.
The kernel can't distinguish from a real keyboard keypress and wakes the
system.
Add the model into the list of quirks to disable keyboard wakeup source.
This is intentionally only matching the production BIOS version in hopes
that a newer EC firmware included in a newer BIOS can avoid this behavior.

The KERNEL_FPR mask only contains a flag for the first eight vector
registers. However floating point registers overlay parts of the first
sixteen vector registers.
This could lead to vector register corruption if a kernel fpu context uses
any of the vector registers 8 to 15 and is interrupted or calls a
KERNEL_FPR context. If that context uses also vector registers 8 to 15,
their contents will be corrupted on return.
Luckily this is currently not a real bug, since the kernel has only one
KERNEL_FPR user with s390_adjust_jiffies() and it is only using floating
point registers 0 to 2.
Fix this by using the correct bits for KERNEL_FPR.

mptcp: misc. fixes for v6.7
Here are a few fixes related to MPTCP:
Patch 1 avoids skipping some subtests of the MPTCP Join selftest by
mistake when using older versions of GCC. This fixes a patch introduced
in v6.4, backported up to v6.1.
Patch 2 fixes an inconsistent state when using MPTCP + FastOpen. A fix
for v6.2.
Patch 3 adds a description for MPTCP Kunit test modules to avoid a
warning.
Patch 4 adds an entry to the mailmap file for Geliang's email addresses.

The netlink PM can race with fastopen self-connect attempts, shutting
down the first subflow via:
MPTCP_PM_CMD_DEL_ADDR -> mptcp_nl_remove_id_zero_address ->
mptcp_pm_nl_rm_subflow_received -> mptcp_close_ssk
and transitioning such subflow to FIN_WAIT1 status before the syn-ack
packet is processed. The MPTCP code does not react to such state change,
leaving the connection in not-fallback status and the subflow handshake
uncompleted, triggering the following splat:

To address the issue, catch the racing subflow state change and
use it to cause the MPTCP fallback. Such fallback is also used to
cause the first subflow state propagation to the msk socket via
mptcp_set_connected(). After this change, the first subflow can
additionally propagate the TCP_FIN_WAIT1 state, so rename the
helper accordingly.
Finally, if the state propagation is delayed to the msk release
callback, the first subflow can change to a different state in between.
Cache the relevant target state in a new msk-level field and use
such value to update the msk state at release time.

MPC backups tests will skip unexpected sometimes (For example, when
compiling kernel with an older version of gcc, such as gcc-8), since
static functions like mptcp_subflow_send_ack also be listed in
/proc/kallsyms, with a 't' in front of it, not 'T' ('T' is for a global
function):
> grep "mptcp_subflow_send_ack" /proc/kallsyms
0000000000000000 T __pfx___mptcp_subflow_send_ack
0000000000000000 T __mptcp_subflow_send_ack
0000000000000000 t __pfx_mptcp_subflow_send_ack
0000000000000000 t mptcp_subflow_send_ack
In this case, mptcp_lib_kallsyms_doesnt_have "mptcp_subflow_send_ack$"
will be false, MPC backups tests will skip. This is not what we expected.
The correct logic here should be: if mptcp_subflow_send_ack is not a
global function in /proc/kallsyms, do these MPC backups tests. So a 'T'
must be added in front of mptcp_subflow_send_ack.

net: phy: add PHY package base addr + mmd APIs
This small series is required for the upcoming qca807x PHY that
will make use of PHY package mmd API and the new implementation
with read/write based on base addr.
The MMD PHY package patch currently has no use but it will be
used in the upcoming patch and it does complete what a PHY package
may require in addition to basic read/write to setup global PHY address.

Some PHY in PHY package may require to read/write MMD regs to correctly
configure the PHY package.
Add support for these additional required function in both lock and no
lock variant.
It's assumed that the entire PHY package is either C22 or C45. We use
C22 or C45 way of writing/reading to mmd regs based on the passed phydev
whether it's C22 or C45.

Restructure phy_write_mmd and phy_read_mmd to implement generic helper
for direct mdiobus access for mmd and use these helper for phydev user.
This is needed in preparation of PHY package API that requires generic
access to the mdiobus and are deatched from phydev struct but instead
access them based on PHY package base_addr and offsets.

Current API for PHY package are limited to single address to configure
global settings for the PHY package.
It was found that some PHY package (for example the qca807x, a PHY
package that is shipped with a bundle of 5 PHY) requires multiple PHY
address to configure global settings. An example scenario is a PHY that
have a dedicated PHY for PSGMII/serdes calibrarion and have a specific
PHY in the package where the global PHY mode is set and affects every
other PHY in the package.
Change the API in the following way:
- Change phy_package_join() to take the base addr of the PHY package
instead of the global PHY addr.
- Make __/phy_package_write/read() require an additional arg that
select what global PHY address to use by passing the offset from the
base addr passed on phy_package_join().
Each user of this API is updated to follow this new implementation
following a pattern where an enum is defined to declare the offset of the
addr.
We also drop the check if shared is defined as any user of the
phy_package_read/write is expected to use phy_package_join first. Misuse
of this will correctly trigger a kernel panic for NULL pointer
exception.

Switch addr type in phy_package_shared struct to u8.
The value is already checked to be non negative and to be less than

On some silicon variants the number of available CAM entries are
less. Reserving one entry for each NIX-LF for default DMAC based pkt
forwarding rules will reduce the number of available CAM entries
further. Hence add configurability via devlink to set maximum number of
NIX-LFs needed which inturn frees up some CAM entries.

Pull CXL (Compute Express Link) fixes from Dan Williams:
"A collection of CXL fixes.
The touch outside of drivers/cxl/ is for a helper that allocates
physical address space. Device hotplug tests showed that the driver
failed to utilize (skipped over) valid capacity when allocating a new
memory region. Outside of that, new tests uncovered a small crop of
lockdep reports.
There is also some miscellaneous error path and leak fixups that are
not urgent, but useful to cleanup now.
- Fix alloc_free_mem_region()'s scan for address space, prevent false
negative out-of-space events
- Fix sleeping lock acquisition from CXL trace event (atomic context)
- Fix put_device() like for the new CXL PMU driver
- Fix wrong pointer freed on error path
- Fixup several lockdep reports (missing lock hold) from new
assertion in cxl_num_decoders_committed() and new tests"
