rose /proc code does not serialize timer accesses.
Initial report by Bernard F6BVP Pidoux exhibits overflow amounting
to 116 ticks on its HZ=250 system.
Full timer access serialization would imho be overkill as rose /proc
does not enforce consistency between displayed ROSE_STATE_XYZ and
timer values during changes of state.
The patch may also fix similar behavior in ax25 /proc, ax25 ioctl
and netrom /proc as they all exhibit the same timer serialization
policy. This point has not been reported though.
The sole remaining use of ax25_display_timer - ax25 rtt valuation -
may also perform marginally better but I have not analyzed it too
deeply.

For packets scheduled to RPM and LBK, NIX_AF_PSE_CHANNEL_LEVEL[BP_LEVEL]
selects the TL3 or TL2 scheduling level as the one used for link/channel
selection and backpressure. For each scheduling queue at the selected
level: Setting NIX_AF_TL3_TL2(0..255)_LINK(0..12)_CFG[ENA] = 1 allows
the TL3/TL2 queue to schedule packets to a specified RPM or LBK link
and channel.
There is an issue in the code where NIX_AF_PSE_CHANNEL_LEVEL[BP_LEVEL]
is set to TL3 where as the NIX_AF_TL3_TL2(0..255)_LINK(0..12)_CFG is
configured for TL2 queue in some cases. As a result packets will not
transmit on that link/channel. This patch fixes the issue by configuring
the NIX_AF_TL3_TL2(0..255)_LINK(0..12)_CFG register depending on the
NIX_AF_PSE_CHANNEL_LEVEL[BP_LEVEL] value.

====================
Octeontx2 AF driver fixes for NPC
This patchset includes AF driver fixes wrt packet parser NPC.
Following are the changes:
Patch 1: The parser nibble configuration must be same for
TX and RX interfaces and if not fix up is applied. This fixup was
applied only for default profile currently and it has been fixed
to apply for all profiles.
Patch 2: Firmware image may not be present all times in the kernel image
and default profile is used mostly hence suppress the warning.
Patch 3: This patch fixes a corner case where NIXLF is detached but
without freeing its mcam entries which results in resource leak.
Patch 4: SMAC is overlapped with DMAC mistakenly while installing
rules based on SMAC. This patch fixes that.

cow fork
On a higly fragmented filesystem a Direct IO write can fail with -ENOSPC error
even though the filesystem has sufficient number of free blocks.
This occurs if the file offset range on which the write operation is being
performed has a delalloc extent in the cow fork and this delalloc extent
begins much before the Direct IO range.
In such a scenario, xfs_reflink_allocate_cow() invokes xfs_bmapi_write() to
allocate the blocks mapped by the delalloc extent. The extent thus allocated
may not cover the beginning of file offset range on which the Direct IO write
was issued. Hence xfs_reflink_allocate_cow() ends up returning -ENOSPC.
The following script reliably recreates the bug described above.
#!/usr/bin/bash

I /think/ this can happen if xfs_qm_flush_one is racing with
xfs_qm_dquot_isolate (i.e. dquot reclaim) when the second function has
taken the dquot flush lock but xfs_qm_dqflush hasn't yet locked the
dquot buffer, let alone queued it to the delwri list. In this case,
flush_one will fail to get the dquot flush lock, but it can lock the
incore buffer, but xfs_buf_delwri_pushbuf will then trip over this
ASSERT, which checks that the buffer isn't on a delwri list. The hang
results because the _delwri_submit_buffers ignores non DELWRI_Q buffers,
which means that xfs_buf_iowait waits forever for an IO that has not yet
been scheduled.
AFAICT, a reasonable solution here is to detect a dquot buffer that is
not on a DELWRI list, drop it, and return -EAGAIN to try the flush
again. It's not /that/ big of a deal if quotacheck writes the dquot
buffer repeatedly before we even set QUOTA_CHKD.

If a blkdev_issue_flush fails, fsync needs to report that to upper
levels. Modify xfs_file_fsync to capture the errors, while trying to
flush as much data and log updates to disk as possible.
If log writes cannot flush the data device, we need to shut down the log
immediately because we've violated a log invariant. Modify this code to
check the return value of blkdev_issue_flush as well.
This behavior seems to go back to about 2.6.15 or so, which makes this
fixes tag a bit misleading.

Vishal notes that when attempting to define a second pmem region on a
device the DPA allocation fails with a message of the form:
decoder11.1: failed to reserve skipped space
Recall that the skip setting is used when there is a pmem allocation in
the presence of free ram DPA space. The first pmem allocation skips over
the free ram and subsequent pmem allocations do not require a skip. The
bug is that a skip is still attempted and the DPA reservation code
flags the double skip allocation conflict.

The endpoint decode granularity must be <= the window granularity
otherwise capacity in the endpoints is lost in the decode. Consider an
attempt to have a region granularity of 512 with 4 devices within a
window that maps 2 host bridges at a granularity of 256 bytes:
HPA DPA Offset HB Port EP
0x0 0x0 0 0 0
0x100 0x0 1 0 2
0x200 0x100 0 0 0
0x300 0x100 1 0 2
0x400 0x200 0 1 1
0x500 0x200 1 1 3
0x600 0x300 0 1 1
0x700 0x300 1 1 3
0x800 0x400 0 0 0
0x900 0x400 1 0 2
0xA00 0x500 0 0 0
0xB00 0x500 1 0 2
Notice how endpoint0 maps HPA 0x0 and 0x200 correctly, but then at HPA
0x800 it results in DPA 0x200-0x400 on being skipped.
Fix this by restricing the region granularity to be equal to the window
granularity resulting in the following for a x4 region under a x2 window
at a granularity of 256.
HPA DPA Offset HB Port EP
0x0 0x0 0 0 0
0x100 0x0 1 0 2
0x200 0x0 0 1 1
0x300 0x0 1 1 3
0x400 0x100 0 0 0
0x500 0x100 1 0 2
0x600 0x100 0 1 1
0x700 0x100 1 1 3
Not that it ever made practical sense to support region granularity >
window granularity. The window rotates host bridges causing endpoints to
never see a consecutive stream of requests at the desired granularity
without breaks to issue cycles to the other host bridge.

In cases where the decode fans out as it traverses downstream, the
interleave granularity needs to increment to identify the port selector
bits out of the remaining address bits. For example, recall that with an
x2 parent port intereleave (IW == 1), the downstream decode for children
of those ports will either see address bit IG+8 always set, or address
bit IG+8 always clear. So if the child port needs to select a downstream
port it can only use address bits starting at IG+9 (where IG and IW are
the CXL encoded values for interleave granularity (ilog2(ig) - 8) and
ways (ilog2(iw))).
When the parent port interleave is x1 no such masking occurs and the
child port can maintain the granularity that was routed to the parent
port.

- Fix probe/remove methods in cafe NAND
- Support unprotected spare data pages in qcom_nandc
SPI NOR core changes:
- move SECT_4K_PMC flag out of the core as it's a vendor specific
flag
- s/addr_width/addr_nbytes/g: address width means the number of IO
lines used for the address, whereas in the code it is used as the
number of address bytes.
- do not change nor->addr_nbytes at SFDP parsing time. At the SFDP
parsing time we should not change members of struct spi_nor, but
instead fill members of struct spi_nor_flash_parameters which could
later on be used by the callers.
- track flash's internal address mode so that we can use 4B opcodes
together with opcodes that don't have a 4B opcode correspondent.
SPI NOR manufacturer drivers changes:
- esmt: Rename "f25l32qa" flash name to "f25l32qa-2s".
- micron-st: Skip FSR reading if SPI controller does not support it
to allow flashes that support FSR to work even when attached to
such SPI controllers.

git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
Pull tracing updates from Steven Rostedt:
- Runtime verification infrastructure
This is the biggest change here. It introduces the runtime
verification that is necessary for running Linux on safety critical
systems.
It allows for deterministic automata models to be inserted into the
kernel that will attach to tracepoints, where the information on
these tracepoints will move the model from state to state.
If a state is encountered that does not belong to the model, it will
then activate a given reactor, that could just inform the user or
even panic the kernel (for which safety critical systems will detect
and can recover from).
- Two monitor models are also added: Wakeup In Preemptive (WIP - not to
be confused with "work in progress"), and Wakeup While Not Running
(WWNR).
- Added __vstring() helper to the TRACE_EVENT() macro to replace
several vsnprintf() usages that were all doing it wrong.
- eprobes now can have their event autogenerated when the event name is
left off.
- The rest is various cleanups and fixes.

Currently much of the smb1 code is built even when
CONFIG_CIFS_ALLOW_INSECURE_LEGACY is disabled.
Move cifssmb.c to only be compiled when insecure legacy is disabled,
and move various SMB1/CIFS helper functions to that ifdef. Some
functions that were not SMB1/CIFS specific needed to be moved out of
cifssmb.c
This shrinks cifs.ko by more than 10% which is good - but also will
help with the eventual movement of the legacy code to a distinct
module. Follow on patches can shrink the number of ifdefs by
code restructuring where smb1 code is wedged in functions that
should be calling dialect specific helper functions instead,
and also by moving some functions from file.c/dir.c/inode.c into
smb1 specific c files.

Jonathan notes:
"Curiously interleave ways = 1 for the EPs which is obviously wrong"
...while testing the latest CXL development branch on QEMU.
It turns out the region creation process failed to program the endpoint
decoders. This was missed because the default settings of x1 at 4K
intereleave still results in the region appearing to function. Jonathan
caught the bug by reverse mapping the translations that need to happen
for the QEMU support.

Dan reports:
The error handling in cxl_port_attach_region() looks like it might
have a similar bug. The cxl_rr->nr_targets++; might want a --.
That function is more complicated.
Indeed cxl_rr->nr_targets leaks when cxl_rr_ep_add() fails, but that
flow is not clear. Fix the bug and the clarity by separating the 'new'
region-reference case from the 'extend' region-reference case. This also
moves the host-physical-address (HPA) validation, that the HPA of a new
region being accounted to the port is greater than the HPA of all other
regions associated with the port, to alloc_region_ref().
Introduce @nr_targets_inc to track when the error exit path needs to
clean up cxl_rr->nr_targets.

The re-checking of loop termination conditions to determine "success"
makes it hard to see that @rc is initialized in all cases. Remove those
to make it explicit that @rc reflects a commit error and that the rest
of logic is concerned with unwinding committed decoders.
This change potentially results in cxl_region_decode_reset() being
