026e680b0a pwm: A fix targeting v6.9-rc3
This fixes a regression intoduced by an off-by-one in v6.9-rc1 making
 the pwm-pxa and the pwm driver in ti-sn65dsi86 unusable for most
 consumer drivers because the default period wasn't set.

43853e843a arm64: dts: rockchip: Remove unsupported node from the Pinebook Pro dts
Remove a redundant node from the Pine64 Pinebook Pro dts, which is intended
to provide a value for the delay in PCI Express enumeration, but that isn't
supported without additional out-of-tree kernel patches.

There were already efforts to upstream those kernel patches, because they
reportedly make some PCI Express cards (such as LSI SAS HBAs) usable in
Pine64 RockPro64 (which is also based on the RK3399);  otherwise, those PCI
Express cards fail to enumerate.  However, providing the required background
and explanations proved to be a tough nut to crack, which is the reason why
those patches remain outside of the kernel mainline for now.

If those out-of-tree patches eventually become upstreamed, the resulting
device-tree changes will almost surely belong to the RK3399 SoC dtsi.  Also,
the above-mentioned unusable-without-out-of-tree-patches PCI Express devices
are in all fairness not usable in a Pinebook Pro without some extensive
hardware modifications, which is another reason to delete this redundant
node.  When it comes to the Pinebook Pro, only M.2 NVMe SSDs can be installed
out of the box (using an additional passive adapter PCB sold separately by
Pine64), which reportedly works fine with no additional patches.

24a9799aa8 smb: client: fix UAF in smb2_reconnect_server()
The UAF bug is due to smb2_reconnect_server() accessing a session that
is already being teared down by another thread that is executing
__cifs_put_smb_ses().  This can happen when (a) the client has
connection to the server but no session or (b) another thread ends up
setting @ses->ses_status again to something different than
SES_EXITING.

To fix this, we need to make sure to unconditionally set
@ses->ses_status to SES_EXITING and prevent any other threads from
setting a new status while we're still tearing it down.

The following can be reproduced by adding some delay to right after
the ipc is freed in __cifs_put_smb_ses() - which will give
smb2_reconnect_server() worker a chance to run and then accessing
@ses->ipc:

kinit ...
mount.cifs //srv/share /mnt/1 -o sec=krb5,nohandlecache,echo_interval=10
[disconnect srv]
ls /mnt/1 &>/dev/null
sleep 30
kdestroy
[reconnect srv]
sleep 10
umount /mnt/1

2bec1bbd55 dlm: remove callback reference counting

Copy interesting callback info into the lkb struct rather
than maintaining pointers to callback structs from the lkb.

986ae3c2a8 dlm: fix race between final callback and remove
This patch fixes the following issue:

node 1 is dir
node 2 is master
node 3 is other

1->2: unlock
2: put final lkb, rsb moved to toss
2->1: unlock_reply
1: queue lkb callback with EUNLOCK
2->1: remove
1: receive_remove ignored (rsb on keep because of queued lkb callback)
1: complete lkb callback, put_lkb, move rsb to toss
3->1: lookup
1->3: lookup_reply master=2
3->2: request
2->3: request_reply EBADR

In summary:
An unexpected lkb reference causes the rsb to remain on the wrong list.
The rsb being on the wrong list causes receive_remove to be ignored.
An ignored receive_remove causes inconsistent dir and master state.

This sequence requires an unusually long delay in delivering the unlock
callback, because the remove message from 2->1 usually happens after
some seconds.  So, it's not known exactly how frequently this sequence
occurs in pratice.  It's possible that the same end result could also
have another unknown cause.

The solution for this issue is to further separate callback state
from the lkb, so that an lkb reference (and from that, an rsb ref)
are not held while a callback remains queued.  Then, within the
unlock_reply, the lkb will be freed and the rsb moved to the toss
list. So, the receive_remove will not be ignored.

ad191e0eee dlm: fix user space lock decision to copy lvb
This patch fixes the copy lvb decision for user space lock requests.
Checking dlm_lvb_operations is done earlier, where granted/requested
lock modes are available to use in the matrix.

The decision had been moved to the wrong location, where granted mode
and requested mode where the same, which causes the dlm_lvb_operations
matix to produce the wrong copy decision. For PW or EX requests, the
caller could get invalid lvb data.

a46c27026d blk-mq: don't schedule block kworker on isolated CPUs
Kernel parameter of `isolcpus=` or 'nohz_full=' are used to isolate CPUs
for specific task, and it isn't expected to let block IO disturb these CPUs.
blk-mq kworker shouldn't be scheduled on isolated CPUs. Also if isolated
CPUs is run for blk-mq kworker, long block IO latency can be caused.

Kernel workqueue only respects CPU isolation for WQ_UNBOUND, for bound
WQ, the responsibility is on user because CPU is specified as WQ API
parameter, such as mod_delayed_work_on(cpu), queue_delayed_work_on(cpu)
and queue_work_on(cpu).

So not run blk-mq kworker on isolated CPUs by removing isolated CPUs
from hctx->cpumask. Meantime use queue map to check if all CPUs in this
hw queue are offline instead of hctx->cpumask, this way can avoid any
cost in fast IO code path, and is safe since hctx->cpumask are only
used in the two cases.

Only moving whole files, fixing Makefile and bunch of includes.

Some changes to ice_devlink file was done even in representor part (Tx
topology), so keep it as final patch to not mess up with rebasing.

After moving to devlink folder there is no need to have such long name
for these files. Rename them to simple devlink.

95ad92d687 ice: Add switch recipe reusing feature
New E810 firmware supports the corresponding functionality, so the driver
allows PFs to subscribe the same switch recipes. Then when the PF is done
with a switch recipes, the PF can ask firmware to free that switch recipe.

When users configure a rule to PFn into E810 switch component, if there is
no existing recipe matching this rule's pattern, the driver will request
firmware to allocate and return a new recipe resource for the rule by
calling ice_add_sw_recipe() and ice_alloc_recipe(). If there is an existing
recipe matching this rule's pattern with different key value, or this is a
same second rule to PFm into switch component, the driver checks out this
recipe by calling ice_find_recp(), the driver will tell firmware to share
using this same recipe resource by calling ice_subscribable_recp_shared()
and ice_subscribe_recipe().

When firmware detects that all subscribing PFs have freed the switch
recipe, firmware will free the switch recipe so that it can be reused.

This feature also fixes a problem where all switch recipes would eventually
be exhausted because switch recipes could not be freed, as freeing a shared
recipe could potentially break other PFs that were using it.

d29a8134c7 ice: avoid the PTP hardware semaphore in gettimex64 path
The PTP hardware semaphore (PFTSYN_SEM) is used to synchronize
operations that program the PTP timers. The operations involve issuing
commands to the sideband queue. The E810 does not have a hardware
sideband queue, so the admin queue is used. The admin queue is slow.
I have observed delays in hundreds of milliseconds waiting for
ice_sq_done.

When phc2sys reads the time from the ice PTP clock and PFTSYN_SEM is
held by a task performing one of the slow operations, ice_ptp_lock can
easily time out. phc2sys gets -EBUSY and the kernel prints:
  ice 0000:XX:YY.0: PTP failed to get time
These messages appear once every few seconds, causing log spam.

The E810 datasheet recommends an algorithm for reading the upper 64 bits
of the GLTSYN_TIME register. It matches what's implemented in
ice_ptp_read_src_clk_reg. It is robust against wrap-around, but not
necessarily against the concurrent setting of the register (with
GLTSYN_CMD_{INIT,ADJ}_TIME commands). Perhaps that's why
ice_ptp_gettimex64 also takes PFTSYN_SEM.

The race with time setters can be prevented without relying on the PTP
hardware semaphore. Using the "ice_adapter" from the previous patch,
we can have a common spinlock for the PFs that share the clock hardware.
It will protect the reading and writing to the GLTSYN_TIME register.
The writing is performed indirectly, by the hardware, as a result of
the driver writing GLTSYN_CMD_SYNC in ice_ptp_exec_tmr_cmd. I wasn't
sure if the ice_flush there is enough to make sure GLTSYN_TIME has been
updated, but it works well in my testing.

My test code can be seen here:
https://gitlab.com/mschmidt2/linux/-/commits/ice-ptp-host-side-lock-10
It consists of:
 - kernel threads reading the time in a busy loop and looking at the
   deltas between consecutive values, reporting new maxima.
 - a shell script that sets the time repeatedly;
 - a bpftrace probe to produce a histogram of the measured deltas.
Without the spinlock ptp_gltsyn_time_lock, it is easy to see tearing.
Deltas in the [2G, 4G) range appear in the histograms.
With the spinlock added, there is no tearing and the biggest delta I saw
was in the range [1M, 2M), that is under 2 ms.

0e2bddf9e5 ice: add ice_adapter for shared data across PFs on the same NIC
There is a need for synchronization between ice PFs on the same physical
adapter.

Add a "struct ice_adapter" for holding data shared between PFs of the
same multifunction PCI device. The struct is refcounted - each ice_pf
holds a reference to it.

Its first use will be for PTP. I expect it will be useful also to
improve the ugliness that is ice_prot_id_tbl.
