git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms into irq/urgent
Pull irqchip fixes from Marc Zyngier:
- Fix the mbigen driver to properly free its MSI descriptors on teardown
- Fix the TI INTA driver to avoid handling spurious interrupts from masked interrupts
- Fix the SiFive PLIC driver to use the correct interrupt priority mask
- Fix the Amlogic Meson gpio driver creative locking
- Fix the GICv4.1 virtual SGI set_affinity callback to update the effective affinity
- Allow the GICv4.x driver to synchronize with the HW pending table parsing
- Fix a couple of missing static attributes

The copy_to/from_user() functions return the number of bytes remaining
but we want to return negative error codes. I changed a couple checks
in raw_ioctl_ep_read() and raw_ioctl_ep0_read() to show that we still
we returning zero on error.

If queue->size check in raw_event_queue_fetch() fails (which normally
shouldn't happen, that check is a fail-safe), the function returns
without reenabling interrupts. This patch fixes that issue, along with
propagating the cause of failure to the function caller.

A DMA transfer can be in progress while vbus is lost due to a cable

peripheral hang. The patch ensures that endpoints are disabled before

[ 13.886857] lock(&irq_desc_lock_class);
[ 13.891014]
[ 13.891014] *** DEADLOCK ***
The issue can occur when CPU1 is doing something like irq_set_type()
and CPU0 performing an interrupt allocation, for example. Taking
an interrupt (like the one being reconfigured) would lead to a deadlock.
A solution to this is:
- Reorder the locking so that meson_gpio_irq_update_bits takes the lock
itself at all times, instead of relying on the caller to lock or not,
hence making the RMW sequence atomic,
- Rework the critical section in meson_gpio_irq_request_channel to only
cover the allocation itself, and let the gpio_irq_sel_pin callback
deal with its own locking if required,
- Take the private spin-lock with interrupts disabled at all times

The ti_sci_inta_irq_handler() does not take into account INTA IRQs state
(masked/unmasked) as it uses INTA_STATUS_CLEAR_j register to get INTA IRQs
status, which provides raw status value.
This causes hard IRQ handlers to be called or threaded handlers to be
scheduled many times even if corresponding INTA IRQ is masked.
Above, first of all, affects the LEVEL interrupts processing and causes
unexpected behavior up the system stack or crash.
Fix it by using the Interrupt Masked Status INTA_STATUSM_j register which
provides masked INTA IRQs status.

A request may not be completed because not all the TRBs are prepared for
it. This happens when we run out of available TRBs. When some TRBs are
completed, the driver needs to prepare the rest of the TRBs for the
request. The check dwc3_gadget_ep_request_completed() shouldn't be
checking the amount of data received but rather the number of pending
TRBs. Revise this request completion check.

If an error occurs in q6v5_probe() after the proxy power domains
are attached, but before qcom_add_ipa_notify_subdev() is called,
qcom_remove_ipa_notify_subdev() is called in the error path, which
is a bug. Fix this by having that call be reached through a
different label.
Additionally, if qcom_add_sysmon_subdev() returns an error, the
subdevs that had already been added will not be properly removed.
Fix this by having the added subdevs (including the IPA notify one)
be removed in this case.
Finally, arrange for the sysmon subdev to be removed before the rest
in the event rproc_add() returns an error.
Have cleanup activity done in q6v5_remove() be done in the reverse
order they are set up in q6v5_probe() (the same order they're done
in the q6v5_probe() error path). Use a local variable for the
remoteproc pointer, which is used repeatedly.

The driver uses __napi_schedule_irqoff() which is fine as long as it is
invoked with disabled interrupts by everybody. Since the commit
mentioned below the driver may invoke xgbe_isr_task() in tasklet/softirq
context. This may lead to list corruption if another driver uses
__napi_schedule_irqoff() in IRQ context.
Use __napi_schedule() which safe to use from IRQ and softirq context.

After commit bfcb813203e619a8960a819bf533ad2a108d8105 ("net: dsa:
configure the MTU for switch ports") my Lamobo R1 platform which uses
an allwinner,sun7i-a20-gmac compatible Ethernet MAC started to fail
by rejecting a MTU of 1536. The reason for that is that the DMA
capabilities are not readable on this version of the IP, and there
is also no 'tx-fifo-depth' property being provided in Device Tree. The
property is documented as optional, and is not provided.
Chen-Yu indicated that the FIFO sizes are 4KB for TX and 16KB for RX, so
provide these values through platform data as an immediate fix until
various Device Tree sources get updated accordingly.

"This fixes a small race between allocating a snapshot buffer and

On a slow machine, the trigger can occur before the snapshot is

trigger fixes the problem"

If seq_file .next function does not change position index,
read after some lseek can generate unexpected output:
$ dd if=/proc/keys bs=1 # full usual output

But a read after lseek in middle of last line results in the partial

Move the inode dirty data flushing to a workqueue so that multiple
threads can take advantage of a single thread's flushing work. The
ratelimiting technique used in bdd4ee4 was not successful, because
threads that skipped the inode flush scan due to ratelimiting would
ENOSPC early, which caused occasional (but noticeable) changes in
behavior and sporadic fstest regressions.
Therefore, make all the writer threads wait on a single inode flush,
which eliminates both the stampeding hordes of flushers and the small
window in which a write could fail with ENOSPC because it lost the
ratelimit race after even another thread freed space.

in 'nxt' in the previous loop iteration.
