This is more changes than I'd like this late although the diffstat is
still fairly small, I kept on holding off as new fixes came in to give
things time to soak in -next but should probably have tagged and sent an
additional pull request earlier.
There's some relatively large fixes to the twl6030 driver to fix issues
with the TWL6032 variant which resulted from some work on the core
TWL6030 driver, a couple of fixes for error handling paths (mostly in
the core), and a nice stability fix for the sgl51000 driver that's been
pulled out of a BSP.

"Weekly fixes, amdgpu has not quite settled down.
Most of the changes are small, and the non-amdgpu ones are all fine.
There are a bunch of DP MST DSC fixes that fix some issues introduced
in a previous larger MST rework.
The biggest one is mainly propagating some error values properly
instead of bool returns, and I think it just looks large but doesn't
really change anything too much, except propagating errors that are
required to avoid deadlocks. I've gone over it and a few others and
they've had some decent testing over the last few weeks.

By looking up the source code and communicating with Pavel, the
implementation of this atomic poll refs should continue the loop of
io_poll_check_events() just to avoid somewhere else to grab the
ownership. Therefore, this patch simply adds another AND operation to
make sure the loop will stop if it finds the poll_refs is exactly equal
to IO_POLL_CANCEL_FLAG. Since io_poll_cancel_req() grabs ownership and
will finally make its way to io_req_complete_failed(), the req will
be reclaimed as expected.

[ 14.083622] ==================================================================
The actual tracing of this bug is shown below:
commit 8c71fe7502 ("io_uring: ensure fput() called correspondingly
when direct install fails") adds an additional fput() in
io_fixed_fd_install() when io_file_bitmap_get() returns error values. In
that case, the routine will never make it to io_install_fixed_file() due
to an early return.
static int io_fixed_fd_install(...)
{
if (alloc_slot) {
...
ret = io_file_bitmap_get(ctx);
if (unlikely(ret < 0)) {
io_ring_submit_unlock(ctx, issue_flags);
fput(file);
return ret;
}
...
}
...
ret = io_install_fixed_file(req, file, issue_flags, file_slot);
...
}
In the above scenario, the reference is okay as io_fixed_fd_install()
ensures the fput() is called when something bad happens, either via
bitmap or via inner io_install_fixed_file().
However, the commit 61c1b44a21 ("io_uring: fix deadlock on iowq file
slot alloc") breaks the balance because it places fput() into the common
path for both io_file_bitmap_get() and io_install_fixed_file(). Since
io_install_fixed_file() handles the fput() itself, the reference
underflow come across then.
There are some extra commits make the current code into
io_fixed_fd_install() -> __io_fixed_fd_install() ->
io_install_fixed_file()
However, the fact that there is an extra fput() is called if
io_install_fixed_file() calls fput(). Traversing through the code, I
find that the existing two callers to __io_fixed_fd_install():
io_fixed_fd_install() and io_msg_send_fd() have fput() when handling
error return, this patch simply removes the fput() in
io_install_fixed_file() to fix the bug.

poll_refs carry two functions, the first is ownership over the request.
The second is notifying the io_poll_check_events() that there was an
event but wake up couldn't grab the ownership, so io_poll_check_events()
should retry.
We want to make poll_refs more robust against overflows. Instead of
always incrementing it, which covers two purposes with one atomic, check
if poll_refs is elevated enough and if so set a retry flag without
attempts to grab ownership. The gap between the bias check and following
atomics may seem racy, but we don't need it to be strict. Moreover there
might only be maximum 4 parallel updates: by the first and the second
poll entries, __io_arm_poll_handler() and cancellation. From those four,
only poll wake ups may be executed multiple times, but they're protected
by a spin.

Replace atomically substracting the ownership reference at the end of
arming a poll with a cmpxchg. We try to release ownership by setting 0
assuming that poll_refs didn't change while we were arming. If it did
change, we keep the ownership and use it to queue a tw, which is fully
capable to process all events and (even tolerates spurious wake ups).
It's a bit more elegant as we reduce races b/w setting the cancellation
flag and getting refs with this release, and with that we don't have to
worry about any kinds of underflows. It's not the fastest path for
polling. The performance difference b/w cmpxchg and atomic dec is
usually negligible and it's not the fastest path.

If a file zone transitions to the offline or readonly state from an
active state, we must clear the zone active flag and decrement the
active seq file counter. Do so in zonefs_account_active() using the new
zonefs inode flags ZONEFS_ZONE_OFFLINE and ZONEFS_ZONE_READONLY. These
flags are set if necessary in zonefs_check_zone_condition() based on the
result of report zones operation after an IO error.

Commit 868f9f2f8e ("vfs: fix copy_file_range() regression in cross-fs
copies") removed fallback to generic_copy_file_range() for cross-fs
cases inside vfs_copy_file_range().
To preserve behavior of nfsd and ksmbd server-side-copy, the fallback to
generic_copy_file_range() was added in nfsd and ksmbd code, but that
call is missing sb_start_write(), fsnotify hooks and more.
Ideally, nfsd and ksmbd would pass a flag to vfs_copy_file_range() that
will take care of the fallback, but that code would be subtle and we got
vfs_copy_file_range() logic wrong too many times already.
Instead, add a flag to explicitly request vfs_copy_file_range() to
perform only generic_copy_file_range() and let nfsd and ksmbd use this
flag only in the fallback path.
This choise keeps the logic changes to minimum in the non-nfsd/ksmbd code
paths to reduce the risk of further regressions.

There are a bunch of late fixes that just came in, in particular
a longer series for Rockchips devicetree files, but most of those
just address cosmetic errors that were found during the binding
validation.
There are a couple of code changes:
- A regression fix to the IXP42x PCI bus
- A fix for a memory leak on optee, and another one for mach-mxs
- Two fixes for the sunxi rsb bus driver, to address
problems with the shutdown logic
The rest are small but important devicetree fixes for a number of
individual boards, addressing issues across all platforms:
- arm global timer on older rockchip SoCs is unstable and
needs to be disabled in favor of a more reliable clocksource
- Corrections to fix bluetooth, mmc, and networking on
a few Rockchip boards
- at91/sam9g20ek UDC needs a pin controller config change
- an omap board runs into mmc probe errors because of regulator
nodes in the wrong place
- imx8mp-evk has a minor inaccuracy with its pin config,
but without user visible impact
- The Allwinner H6 Hantro G2 video decoder needs an IOMMU

The size of the TOD programmable field was incorrectly increased from
four to eight bytes with commit 1a2c5840ac ("s390/dump: cleanup CPU
save area handling").
This leads to an elf notes section NT_S390_TODPREG which has a size of
eight instead of four bytes in case of kdump, however even worse is
that the contents is incorrect: it is supposed to contain only the
contents of the TOD programmable field, but in fact contains a mix of
the TOD programmable field (32 bit upper bits) and parts of the CPU
timer register (lower 32 bits).
Fix this by simply changing the size of the todpreg field within the
save area structure. This will implicitly also fix the size of the
corresponding elf notes sections.
This also gets rid of this compile time warning:

The root cause of the problem is that the queues are not
disable on the error handling path when register_netdevice()
fails in virtnet_probe(), resulting in an error "-ENOENT"
returned in the next modprobe call in setup_vq().
virtio_pci_modern_device uses virtqueues to send or
receive message, and "queue_enable" records whether the
queues are available. In vp_modern_find_vqs(), all queues
will be selected and activated, but once queues are enabled
there is no way to go back except reset.
Fix it by reset virtio device on error handling path. This
makes error handling follow the same order as normal device
cleanup in virtnet_remove() which does: unregister, destroy
failover, then reset. And that flow is better tested than
error handling so we can be reasonably sure it works well.
