Add support for Versal CPM as Root Port.
The Versal ACAP devices include CCIX-PCIe Module (CPM). The integrated
block for CPM along with the integrated bridge can function as PCIe Root
Port.
Bridge error and legacy interrupts in Versal CPM are handled using Versal
CPM specific interrupt line.

Before switch from discontigmem to sparsemem, there always was
CONFIG_NEED_MULTIPLE_NODES=y because it was selected by DISCONTIGMEM.
Without DISCONTIGMEM it is possible to have SPARSEMEM without NUMA for
SGI_IP27 and as many things there rely on custom node definition, the
build breaks.
As Thomas noted "... there are right now too many places in IP27 code,
which assumes NUMA enabled", the simplest solution would be to always
enable NUMA for SGI-IP27 builds.

Pull hmm updates from Jason Gunthorpe:
"Ralph has been working on nouveau's use of hmm_range_fault() and
migrate_vma() which resulted in this small series. It adds reporting
of the page table order from hmm_range_fault() and some optimization
of migrate_vma():
- Report the size of the page table mapping out of hmm_range_fault().
This makes it easier to establish a large/huge/etc mapping in the
device's page table.
- Allow devices to ignore the invalidations during migration in cases
where the migration is not going to change pages.
For instance migrating pages to a device does not require the
device to invalidate pages already in the device.
- Update nouveau and hmm_tests to use the above"

"This is the bulk of GPIO changes for the v5.9 kernel cycle.
There is nothing too exciting in it, but a new macro that fixes a
build failure on a minor ARM32 platform that appeared yesterday is
part of it so we better merge it.
Core changes:
- Introduce the for_each_requested_gpio() macro to help in dependent
code all over the place. Also patch a few locations to use it while
we are at it.
- Split out the sysfs code into its own file.
- Split out the character device code into its own file, then make a
set of refactorings and improvements to this code. We are setting
the stage to revamp the userspace API a bit in the next cycle.
- Fix a whole slew of kerneldoc that was wrong or missing.
New drivers:
- The PCA953x driver now supports the PCAL9535.
Driver improvements:
- A host of incremental modernizations and improvements to the
PCA953x driver.
- Incremental improvements to the Xilinx Zynq driver.
- Some improvements to the GPIO aggregator driver.
- I ran all over the place switching all threaded and other drivers
requesting their own IRQ while using the core GPIO IRQ helpers to
pass the GPIO irq chip as a template instead of calling the
explicit set-up functions. Next merge window we may retire the old

The msg_zerocopy test pins the sender and receiver threads to separate
cores to reduce variance between runs.
But it hardcodes the cores and skips core 0, so it fails on machines
with the selected cores offline, or simply fewer cores.
The test mainly gives code coverage in automated runs. The throughput
of zerocopy ('-z') and non-zerocopy runs is logged for manual
inspection.
Continue even when sched_setaffinity fails. Just log to warn anyone
interpreting the data.

====================
selftests: rtnetlink: Fix for false-negative return values
This patchset will address the false-negative return value issue
caused by the following:
1. The return value "ret" in this script will be reset to 0 from
the beginning of each sub-test in rtnetlink.sh, therefore this
rtnetlink test will always pass if the last sub-test has passed.
2. The test result from two sub-tests in kci_test_encap() were not
being processed, thus they will not affect the final test result
of this test.

kci_test_encap() is actually composed by two different sub-tests,
kci_test_encap_vxlan() and kci_test_encap_fou()

Although we can detect the chip revision 100% at runtime, it is useful
to specify it in the device tree compatible string too, because
otherwise there would be no way to assess the correctness of device tree
bindings statically, without booting a board (only some switch versions
have internal RGMII delays and/or an SGMII port).
But for testing the P/Q/R/S support, what I have is a reworked board
with the SJA1105T replaced by a pin-compatible SJA1105Q, and I don't
want to keep a separate device tree blob just for this one-off board.
Since just the chip has been replaced, its RGMII delay setup is
inherently the same (meaning: delays added by the PHY on the slave
ports, and by PCB traces on the fixed-link CPU port).
For this board, I'd rather have the driver shout at me, but go ahead and
use what it found even if it doesn't match what it's been told is there.
[ 2.970826] sja1105 spi0.1: Device tree specifies chip SJA1105T but found SJA1105Q, please fix it!

Without ub->ifindex set for ipv6 address in tipc_udp_enable(),
ipv6_sock_mc_join() may make the wrong dev join the multicast
address in enable_mcast(). This causes that tipc links would
never be created.
So fix it by getting the right netdev and setting ub->ifindex,
as it does for ipv4 address.

This reverts commit 71130f29979c7c7956b040673e6b9d5643003176.
In commit 71130f29979c ("vxlan: fix tos value before xmit") we want to
make sure the tos value are filtered by RT_TOS() based on RFC1349.
0 1 2 3 4 5 6 7
+-----+-----+-----+-----+-----+-----+-----+-----+
| PRECEDENCE | TOS | MBZ |
+-----+-----+-----+-----+-----+-----+-----+-----+
But RFC1349 has been obsoleted by RFC2474. The new DSCP field defined like
0 1 2 3 4 5 6 7
+-----+-----+-----+-----+-----+-----+-----+-----+
| DS FIELD, DSCP | ECN FIELD |
+-----+-----+-----+-----+-----+-----+-----+-----+
So with
IPTOS_TOS_MASK 0x1E
RT_TOS(tos) ((tos)&IPTOS_TOS_MASK)
the first 3 bits DSCP info will get lost.
To take all the DSCP info in xmit, we should revert the patch and just push
all tos bits to ip_tunnel_ecn_encap(), which will handling ECN field later.

The historic requirement for XFS to invalidate cached pages on
direct IO reads has been lost in the twisty pages of history - it was
inherited from Irix, which implemented page cache invalidation on
read as a method of working around problems synchronising page
cache state with uncached IO.
XFS has carried this ever since. In the initial linux ports it was
necessary to get mmap and DIO to play "ok" together and not
immediately corrupt data. This was the state of play until the linux
kernel had infrastructure to track unwritten extents and synchronise
page faults with allocations and unwritten extent conversions
(->page_mkwrite infrastructure). IOws, the page cache invalidation
on DIO read was necessary to prevent trivial data corruptions. This
didn't solve all the problems, though.
There were peformance problems if we didn't invalidate the entire
page cache over the file on read - we couldn't easily determine if
the cached pages were over the range of the IO, and invalidation
required taking a serialising lock (i_mutex) on the inode. This
serialising lock was an issue for XFS, as it was the only exclusive
lock in the direct Io read path.
Hence if there were any cached pages, we'd just invalidate the
entire file in one go so that subsequent IOs didn't need to take the
serialising lock. This was a problem that prevented ranged
invalidation from being particularly useful for avoiding the
remaining coherency issues. This was solved with the conversion of
i_mutex to i_rwsem and the conversion of the XFS inode IO lock to
use i_rwsem. Hence we could now just do ranged invalidation and the
performance problem went away.
However, page cache invalidation was still needed to serialise
sub-page/sub-block zeroing via direct IO against buffered IO because
bufferhead state attached to the cached page could get out of whack
when direct IOs were issued. We've removed bufferheads from the
XFS code, and we don't carry any extent state on the cached pages
anymore, and so this problem has gone away, too.
IOWs, it would appear that we don't have any good reason to be
invalidating the page cache on DIO reads anymore. Hence remove the
invalidation on read because it is unnecessary overhead,
not needed to maintain coherency between mmap/buffered access and
direct IO anymore, and prevents anyone from using direct IO reads
from intentionally invalidating the page cache of a file.

Tegra HDA has audio data buffer for upto tens of frames, this buffer
can help to avoid underflow. HW will keep issuing new data fetch
request when buffers are not full and current BDL is not done. When SW
disable DMA RUN bit for a stream, HW can't cancel the already issued data
fetch request and hence it can't stop DMA. HW has to wait for all issued
data fetch request get data returned before it stops DMA.
This HW behavior is not in sync with HDA spec which says DMA RUN bit
should be cleared within 1 audio frame. For Tegra, DMA RUN bit was
active for more than one audio frame, due to this the timeout in
snd_hdac_stream_sync function is not helping. When Stream reset set
and clear happens during DMA RUN bit active state it results in Memory
Decode error.
Unfortunately, there is no way to detect when these data accesses have
completed, but testing has shown that a 100us delay between Stream reset
set and clear operation for Tegra avoids the memory decode error.
Therefore, adding a 100us dma stop delay.

Some ioctls via OSS sequencer API may race and lead to UAF when the
port create and delete are performed concurrently, as spotted by a
couple of syzkaller cases. This patch is an attempt to address it by
serializing the ioctls with the existing register_mutex.
Basically OSS sequencer API is an obsoleted interface and was designed
without much consideration of the concurrency. There are very few
applications with it, and the concurrent performance isn't asked,
hence this "big hammer" approach should be good enough.

Pull documentation updates from Jonathan Corbet:
"It's been a busy cycle for documentation - hopefully the busiest for a
while to come. Changes include:
- Some new Chinese translations
- Progress on the battle against double words words and non-HTTPS
URLs
- Some block-mq documentation
- More RST conversions from Mauro. At this point, that task is
essentially complete, so we shouldn't see this kind of churn again
for a while. Unless we decide to switch to asciidoc or
something...:)
- Lots of typo fixes, warning fixes, and more"
