afs: Fix interruption of operations
The afs filesystem driver allows unstarted operations to be cancelled by
signal, but most of these can easily be restarted (mkdir for example). The
primary culprits for reproducing this are those applications that use
SIGALRM to display a progress counter.
File lock-extension operation is marked uninterruptible as we have a
limited time in which to do it, and the release op is marked
uninterruptible also as if we fail to unlock a file, we'll have to wait 20
mins before anyone can lock it again.
The store operation logs a warning if it gets interruption, e.g.:
kAFS: Unexpected error from FS.StoreData -4
because it's run from the background - but it can also be run from
fdatasync()-type things. However, store options aren't marked
interruptible at the moment.
Fix this in the following ways:
(1) Mark store operations as uninterruptible. It might make sense to
relax this for certain situations, but I'm not sure how to make sure
that background store ops aren't affected by signals to foreground
processes that happen to trigger them.
(2) In afs_get_io_locks(), where we're getting the serialisation lock for
talking to the fileserver, return ERESTARTSYS rather than EINTR
because a lot of the operations (e.g. mkdir) are restartable if we
haven't yet started sending the op to the server.

The above patch is supposed to fix a register index error on mt2701. It
is not clear if the problem solved is a hang or just an invalid value
returned, my guess is the second. The patch introduces, though, a new
hang on MT8173 device making them unusable. So, seems reasonable, revert
the patch because introduces a worst issue.
The reason I send a revert instead of trying to fix the issue for MT8173
is because the information needed to fix the issue is in the datasheet
and is not public. So I am not really able to fix it.
Fixes the following bug when CONFIG_MTK_THERMAL is set on MT8173
devices.

drm/i915: Recalculate FBC w/a stride when needed
Currently we're failing to recalculate the gen9 FBC w/a stride
unless something more drastic than just the modifier itself has
changed. This often leaves us with FBC enabled with the linear
fbdev framebuffer without the w/a stride enabled. That will cause
an immediate underrun and FBC will get promptly disabled.
Fix the problem by checking if the w/a stride is about to change,
and go through the full dance if so. This part of the FBC code
is still pretty much a disaster and will need lots more work.
But this should at least fix the immediate issue.

mm: document warning in move_normal_pmd() and make it warn only once
Naresh Kamboju reported that the LTP tests can cause warnings on i386
going back all the way to v5.0, and bisected it to commit 2c91bd4a4e2e
("mm: speed up mremap by 20x on large regions").
The warning in move_normal_pmd() is actually mostly correct, but we have
a very unusual special case at process creation time, when we may move
the stack down with an overlapping mode (kind of like a "memmove()"
except using the page tables).
And when you have just the right condition of "move a large initial
stack by the right alignment in the end, but with the early part of the
move being only page-aligned", we'll be in a situation where we're
trying to move a normal PMD entry on top of an already existing - but
now empty - PMD entry.
The warning is still worth having, in case it ever triggers other cases,
and perhaps as a reminder that we could do the stack move case more
efficiently (although it's clearly rare enough that it probably doesn't
matter).
But make it do WARN_ON_ONCE(), so that you can't flood the logs with it.
And add a *big* comment above it to explain and remind us what's going
on, because it took some figuring out to see how this could trigger.
Kudos to Joel Fernandes for debugging this.

Clang 8 was chosen as a minimum version for this check because there

reality, MIPS was not even buildable until clang 9 so that check was not
technically necessary. Just remove all compiler checks and just assume

mlxsw: pci: Fix use-after-free in case of failed devlink reload
In case devlink reload failed, it is possible to trigger a
use-after-free when querying the kernel for device info via 'devlink dev
info' [1].
This happens because as part of the reload error path the PCI command
interface is de-initialized and its mailboxes are freed. When the
devlink '->info_get()' callback is invoked the device is queried via the
command interface and the freed mailboxes are accessed.
Fix this by initializing the command interface once during probe and not
during every reload.
This is consistent with the other bus used by mlxsw (i.e., 'mlxsw_i2c')
and also allows user space to query the running firmware version (for
example) from the device after a failed reload.

====================
net: macb: Wake-on-Lan magic packet fixes and GEM handling
Here is a split series to fix WoL magic-packet on the current macb driver. Only
fixes in this one based on current net/master.
Changes in v5:
- Addressed the error code returned by phylink_ethtool_set_wol() as suggested
by Russell.
If PHY handles WoL, MAC doesn't stay in the way.
- Removed Florian's tag on 3/5 because of the above changes.
- Correct the "Fixes" tag on 1/5.
Changes in v4:
- Pure bug fix series for 'net'. GEM addition and MACB update removed: will be
sent later.
Changes in v3:
- Revert some of the v2 changes done in macb_resume(). Now the resume function
supports in-depth re-configuration of the controller in order to deal with
deeper sleep states. Basically as it was before changes introduced by this
series
- Tested for non-regression with our deeper Power Management mode which cuts
power to the controller completely
Changes in v2:
- Add patch 4/7 ("net: macb: fix macb_suspend() by removing call to netif_carrier_off()")
needed for keeping phy state consistent
- Add patch 5/7 ("net: macb: fix call to pm_runtime in the suspend/resume functions") that prevent

- Collect review tags on 3 first patches from Florian: Thanks!
- Review of macb_resume() function

Change the way the "magic-packet" DT property is handled in the
macb_probe() function, matching DT binding documentation.
Now we mark the device as "wakeup capable" instead of calling the
device_init_wakeup() function that would enable the wakeup source.
For Ethernet WoL, enabling the wakeup_source is done by
using ethtool and associated macb_set_wol() function that
already calls device_set_wakeup_enable() for this purpose.
That would reduce power consumption by cutting more clocks if
"magic-packet" property is set but WoL is not configured by ethtool.

ALSA: usb-audio: Fix race against the error recovery URB submission
USB MIDI driver has an error recovery mechanism to resubmit the URB in
the delayed timer handler, and this may race with the standard start /
stop operations. Although both start and stop operations themselves
don't race with each other due to the umidi->mutex protection, but
this isn't applied to the timer handler.
For fixing this potential race, the following changes are applied:
- Since the timer handler can't use the mutex, we apply the
umidi->disc_lock protection at each input stream URB submission;
this also needs to change the GFP flag to GFP_ATOMIC
- Add a check of the URB refcount and skip if already submitted
- Move the timer cancel call at disconnection to the beginning of the
procedure; this assures the in-flight timer handler is gone properly
before killing all pending URBs

io_uring: account user memory freed when exit has been queued
We currently account the memory after the exit work has been run, but
that leaves a gap where a process has closed its ring and until the
memory has been accounted as freed. If the memlocked ulimit is
borderline, then that can introduce spurious setup errors returning
-ENOMEM because the free work hasn't been run yet.
Account this as freed when we close the ring, as not to expose a tiny
gap where setting up a new ring can fail.

ALSA: line6: Sync the pending work cancel at disconnection
Recently syzkaller reported a UAF in LINE6 driver, and it's likely
because we call cancel_delayed_work() at the disconnect callback
instead of cancel_delayed_work_sync(). Let's use the correct one
instead.
ALSA: line6: Perform sanity check for each URB creation
LINE6 drivers create stream URBs with a fixed pipe without checking
its validity, and this may lead to a kernel WARNING at the submission
when a malformed USB descriptor is passed.
For avoiding the kernel warning, perform the similar sanity checks for
each pipe type at creating a URB.
Call percpu_ref_exit() on error path to avoid
refcount memleak.

driver core: Avoid deferred probe due to fw_devlink_pause/resume()
With the earlier patch in this series, all devices that deferred probe
due to fw_devlink_pause() will have their probes delayed till the
deferred probe thread is kicked off during late_initcall. This will also
affect all their consumers.
This delayed probing in unnecessary. So this patch just keeps track of
the devices that had their probe deferred due to fw_devlink_pause() and
attempts to probe them once during fw_devlink_resume().
