There are 3 speical error codes: -EAGAIN/-EFBIG/-ESTALE.
After calling try_get_cap_refs, ceph_try_get_caps test for the
-EAGAIN twice. Ensure that it tests for -ESTALE instead.

When serial console has been assigned to ttyPS1 (which is serial1 alias)
console index is not updated property and pointing to index -1 (statically
initialized) which ends up in situation where nothing has been printed on
the port.
The commit 18cc7ac8a28e ("Revert "serial: uartps: Register own uart console

accident.

Commit f458d039db7e ("kvm: ioapic: Lazy update IOAPIC EOI") introduces
the following infinite loop:

The re-entrancy happens because the irq state is the OR of
the interrupt state and the resamplefd state. That is, we don't
want to show the state as 0 until we've had a chance to set the
resamplefd. But if the interrupt has _not_ gone low then
ioapic_set_irq is invoked again, causing an infinite loop.
This can only happen for a level-triggered interrupt, otherwise
irqfd_inject would immediately set the KVM_USERSPACE_IRQ_SOURCE_ID high
and then low. Fortunately, in the case of level-triggered interrupts the VMEXIT already happens because
TMR is set. Thus, fix the bug by restricting the lazy invocation
of the ack notifier to edge-triggered interrupts, the only ones that
need it.

Current logic incorrectly uses the enum ioapic_irq_destination_types
to check the posted interrupt destination types. However, the value was
set using APIC_DM_XXX macros, which are left-shifted by 8 bits.
Fixes by using the APIC_DM_FIXED and APIC_DM_LOWEST instead.

Due to a bug-report that was compiler-dependent, I updated one of my
machines to gcc-10. That shows a lot of new warnings. Happily they
seem to be mostly the valid kind, but it's going to cause a round of
churn for getting rid of them..
This is the really low-hanging fruit of removing a couple of zero-sized
arrays in some core code. We have had a round of these patches before,
and we'll have many more coming, and there is nothing special about
these except that they were particularly trivial, and triggered more
warnings than most.

cachefiles_read_or_alloc_pages()
The patch which changed cachefiles from calling ->bmap() to using the
bmap() wrapper overwrote the running return value with the result of
calling bmap(). This causes an assertion failure elsewhere in the code.
Fix this by using ret2 rather than ret to hold the return value.
The oops looks like:

As of v5.7-rc2, Linux now prints the following message at boot:
[ 33.848525] platform sound_spdif: deferred probe pending
This is because sound_spdif is waiting on its CPU DAI &spdif to probe,
but &spdif is disabled in the device tree.
Exposure of the SPDIF pin is board-specific functionality, so the sound
card and codec DAI belong in the individual board DTS, not the SoC DTSI.
In fact, no in-tree A64 board DTS enables &spdif, so let's remove the
card and DAI entirely.

An older version of the analog codec binding referenced the headphone
amplifier binding as "hpvcc". However, by the time it was merged in
commit 21dd30200e3d ("ASoC: dt-bindings: sun50i-codec-analog: Add
headphone amp regulator supply"), the regulator reference was renamed to
"cpvdd". This board's device tree still uses the old name, which fails
to work at runtime, and which causes a warning from `make dtbs_check`.
Resolve both by fixing the name.

The obvious fix would be to use 'spin_lock_init()' on 'pchan->lock'
before attempting to call 'spin_lock_irqsave()' in 'owl_dma_get_pchan()'.
However, according to Manivannan Sadhasivam, 'pchan->lock' was supposed
to only protect 'pchan->vchan' while 'od->lock' does a similar job in
'owl_dma_terminate_pchan()'.
Therefore, this patch substitutes 'pchan->lock' with 'od->lock' and
removes the 'lock' attribute in 'owl_dma_pchan' struct.

Hugh reported that his trusty G5 crashed after a few hours under load
with an "Unrecoverable exception 380".
The crash is in interrupt_return() where we check lazy_irq_pending(),
which calls get_paca() and with CONFIG_DEBUG_PREEMPT=y that goes to
check_preemption_disabled() via debug_smp_processor_id().
As Nick explained on the list:
Problem is MSR[RI] is cleared here, ready to do the last few things
for interrupt return where we're not allowed to take any other
interrupts.
SLB interrupts can happen just about anywhere aside from kernel
text, global variables, and stack. When that hits, it appears to be
unrecoverable due to RI=0.
The problematic access is in preempt_count() which is:
return READ_ONCE(current_thread_info()->preempt_count);
Because of THREAD_INFO_IN_TASK, current_thread_info() just points to
current, so the access is to somewhere in kernel memory, but not on
the stack or in .data, which means it can cause an SLB miss. If we
take an SLB miss with RI=0 it is fatal.
The easiest solution is to add a version of lazy_irq_pending() that
doesn't do the preemption check and call it from the interrupt return
path.

Commit 317d9313925c ("ALSA: hda/realtek - Set default power save node to
0") makes the ALC225 have pop noise on S3 resume and cold boot.
The previous fix enable power save node universally for ALC225, however
it makes some ALC225 systems unable to produce any sound.
So let's only enable power save node for the affected Dell Wyse
platform.

DMA channel request should use device struct from platform device struct.
Currently it's using iio device struct. But at this stage when probing,
device struct isn't yet registered (e.g. device_register is done in
iio_device_register). Since commit 71723a96b8b1 ("dmaengine: Create
symlinks between DMA channels and slaves"), a warning message is printed
as the links in sysfs can't be created, due to device isn't yet registered:
- Cannot create DMA slave symlink
- Cannot create DMA dma:rx symlink
Fix this by using device struct from platform device to request dma chan.

During initial submission the selection of the channel was done using
the scan_index member of the iio_chan_spec structure. It was an abuse
because this member is supposed to be used with a buffer so it was
removed.
However there was still the need to be able to known how to select a
channel, the correct member to store this information is address.
Thanks to this it is possible to select any other channel than the
channel 0.

If the serial interface is used, the 8-bit address should be latched using
the rising edge of the WR/FSYNC signal.
This basically means that a CS change is required between the first byte
sent, and the second one.
This change splits the single-transfer transfer of 2 bytes into 2 transfers
with a single byte, and CS change in-between.
Note fixes tag is not accurate, but reflects a point beyond which there
are too many refactors to make backporting straight forward.

The snd-firewire-lib.ko has 'amdtp-packet' event of tracepoints. Current
printk format for the event includes 'sizeof(u8)' macro expected to be
extended in compilation time. However, this is not done. As a result,
perf tools cannot parse the event for printing:
$ mount -l -t debugfs

$ cat /sys/kernel/debug/tracing/events/snd_firewire_lib/amdtp_packet/format
