The KSZ9031 PHY skew timings for rxc/txc, originally set to achieve
the desired phase shift between clock- and data-signal, now trigger a
kernel warning when used in rgmii-id mode:
*-skew-ps values should be used only with phy-mode = "rgmii"
This is because commit bcf3440c6d ("net: phy: micrel: add phy-mode
support for the KSZ9031 PHY") now configures own timings when
phy-mode = "rgmii-id". Device trees wanting to set their own delays
should use phy-mode "rgmii" instead as the warning prescribes.
The "standard" timings now used with "rgmii-id" work fine on this
board, so drop the explicit timings in the device tree and thereby
silence the warning.

Some metrics (such as DRAM_BW_Use) consists of uncore events and
duration_time. For uncore events, counter->core.system_wide is true. But
for duration_time, counter->core.system_wide is false so
target.system_wide is set to false.
Then 'enable_on_exec' is set in perf_event_attr of uncore event. Kernel
will return error when trying to open the uncore event.
This patch skips the duration_time in setup_system_wide then
target.system_wide will be set to true for the evlist of uncore events +
duration_time.

During a code inspection, I found a serious bug in the log intent item
recovery code when an intent item cannot complete all the work and
decides to requeue itself to get that done. When this happens, the
item recovery creates a new incore deferred op representing the
remaining work and attaches it to the transaction that it allocated. At
the end of _item_recover, it moves the entire chain of deferred ops to
the dummy parent_tp that xlog_recover_process_intents passed to it, but
fail to log a new intent item for the remaining work before committing
the transaction for the single unit of work.
xlog_finish_defer_ops logs those new intent items once recovery has
finished dealing with the intent items that it recovered, but this isn't
sufficient. If the log is forced to disk after a recovered log item
decides to requeue itself and the system goes down before we call
xlog_finish_defer_ops, the second log recovery will never see the new
intent item and therefore has no idea that there was more work to do.
It will finish recovery leaving the filesystem in a corrupted state.
The same logic applies to /any/ deferred ops added during intent item
recovery, not just the one handling the remaining work.

In xfs_growfs_rt(), we enlarge bitmap and summary files by allocating
new blocks for both files. For each of the new blocks allocated, we
allocate an xfs_buf, zero the payload, log the contents and commit the
transaction. Hence these buffers will eventually find themselves
appended to list at xfs_ail->ail_buf_list.
Later, xfs_growfs_rt() loops across all of the new blocks belonging to
the bitmap inode to set the bitmap values to 1. In doing so, it
allocates a new transaction and invokes the following sequence of
functions,
- xfs_rtfree_range()
- xfs_rtmodify_range()
- xfs_rtbuf_get()
We pass '&xfs_rtbuf_ops' as the ops pointer to xfs_trans_read_buf().
- xfs_trans_read_buf()
We find the xfs_buf of interest in per-ag hash table, invoke
xfs_buf_reverify() which ends up assigning '&xfs_rtbuf_ops' to
xfs_buf->b_ops.
On the other hand, if xfs_growfs_rt_alloc() had allocated a few blocks
for the bitmap inode and returned with an error, all the xfs_bufs
corresponding to the new bitmap blocks that have been allocated would
continue to be on xfs_ail->ail_buf_list list without ever having a
non-NULL value assigned to their b_ops members. An AIL flush operation
would then trigger the following warning message to be printed on the
console,

Common Processor board is the baseboard that has most of the actual
connectors, power supply etc. A SOM (System on Module) is plugged on
to the common processor board and this contains the SoC, PMIC, DDR and
basic high speed components necessary for functionality.
Note:
* The minimum configuration required to boot up the board is System On
Module(SOM) + Common Processor Board.
* Since there is just a single SOM and Common Processor Board, we are
maintaining common processor board as the base dts and SOM as the dtsi
that we include. In the future as more SOM's appear, we should move
common processor board as a dtsi and include configurations as dts.
* All daughter cards beyond the basic boards shall be maintained as
overlays.

It was missed when I was forking Loongson2ef from Loongson64 but
should be applied to Loongson2ef as march=loongson2f
will also enable Loongson MMI in GCC-9+.

Recently we applied a fix to cover the whole OSS sequencer ioctls with
the mutex for dealing with the possible races. This works fine in
general, but in theory, this may lead to unexpectedly long stall if an
ioctl like SNDCTL_SEQ_SYNC is issued and an event with the far future
timestamp was queued.
For fixing such a potential stall, this patch changes the mutex lock
applied conditionally excluding such an ioctl command. Also, change
the mutex_lock() with the interruptible version for user to allow
escaping from the big-hammer mutex.

Updated the reset driver to support Versal platform.
As part of adding Versal support
- Added Versal specific compatible string.
- Reset Id and number of resets are different for Versal and ZynqMP,
hence taken care of these two based on compatible string.

Added documentation and Versal reset indices to describe
about Versal reset driver bindings.
In Versal all reset indices includes Class, SubClass, Type, Index
information whereas class refers to clock, reset, power etc.,
Underlying firmware in Versal have such classification and expects
the ID to be this way.
[13:0] - Index bits
[19:14] - Type bits
[25:20] - SubClass bits
[31:26] - Class bits.

CPUs may fail to enter the chosen idle state if there was a
pending interrupt, causing the cpuidle driver to return an error
value.
Record that and export it via sysfs along with the other idle state
statistics.
This could prove useful in understanding behavior of the governor
and the system during usecases that involve multiple CPUs.
