Commit c312ef176399 "libata/ahci: Drop PCS quirk for Denverton and
beyond" got the polarity wrong on the check for which board-ids should
have the quirk applied. The board type board_ahci_pcs7 is defined at the
end of the list such that "pcs7" boards can be special cased in the
future if they need the quirk. All prior Intel board ids "<
board_ahci_pcs7" should proceed with applying the quirk.

After enabling CONFIG_IOMMU_DMA on X86 a new warning appears when
compiling vfio:
drivers/vfio/vfio_iommu_type1.c: In function ‘vfio_iommu_type1_attach_group’:
drivers/vfio/vfio_iommu_type1.c:1827:7: warning: ‘resv_msi_base’ may be used uninitialized in this function [-Wmaybe-uninitialized]
ret = iommu_get_msi_cookie(domain->domain, resv_msi_base);
~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The warning is a false positive, because the call to iommu_get_msi_cookie()
only happens when vfio_iommu_has_sw_msi() returned true. And that only
happens when it also set resv_msi_base.
But initialize the variable anyway to get rid of the warning.

The current checking for failure on the number of ports fails when
-ENODEV is returned from the call to get_num_ports. Fix this by making
num_ports and loop counter i signed rather than unsigned ints. Also
add check for num_ports being less than zero to check for -ve error
returns.

It seems that the right variable to use in this case is *i*, instead of
*n*, otherwise there is an undefined behavior when right shifiting by more
than 31 bits when multiplying n by 8; notice that *n* can take values
equal or greater than 4 (4, 8, 16, ...).
Also, notice that under the current conditions (bl = 3), we are skiping
the handling of bytes 3, 7, 31... So, fix this by updating this logic
and limit *bl* up to 4 instead of up to 3.
This fix is based on function udc_stuff_fifo().

Dequeuing implementation in cdns3_gadget_ep_dequeue gets first request from
deferred_req_list and changed TRB associated with it to LINK TRB.
This approach is incorrect because deferred_req_list contains requests
that have not been placed on hardware RING. In this case driver should
just giveback this request to gadget driver.
The patch implements new approach that first checks where dequeuing
request is located and only when it's on Transfer Ring then changes TRB
associated with it to LINK TRB.
During processing completed transfers such LINK TRB will be ignored.

It should not have anything to do with code generation.
As such, it should not select DIMLIB for all drivers under

Panfrost uses multiple schedulers (one for each slot, so 2 in reality),
and on a timeout has to stop all the schedulers to safely perform a
reset. However more than one scheduler can trigger a timeout at the same
time. This race condition results in jobs being freed while they are
still in use.
When stopping other slots use cancel_delayed_work_sync() to ensure that
any timeout started for that slot has completed. Also use
mutex_trylock() to obtain reset_lock. This means that only one thread
attempts the reset, the other threads will simply complete without doing
anything (the first thread will wait for this in the call to
cancel_delayed_work_sync()).
While we're here and since the function is already dependent on
sched_job not being NULL, let's remove the unnecessary checks.

There is a warning message in my test with below steps:
# rbd bench --io-type write --io-size 4K --io-threads 1 --io-pattern rand test &
# sleep 5
# pkill -9 rbd
# rbd map test &
# sleep 5
# pkill rbd
The reason is that the rbd_add_acquire_lock() is interruptable,
that means, when we kill the waiting on ->acquire_wait, the lock_dwork
could be still running.
1. do_rbd_add() 2. lock_dwork
rbd_add_acquire_lock()
- queue_delayed_work()
lock_dwork queued
- wait_for_completion_killable_timeout() <-- kill happen
rbd_dev_image_unlock() <-- UNLOCKED now, nothing to do.
rbd_dev_device_release()
rbd_dev_image_release()
- ...
lock successed here
- cancel_delayed_work_sync(&rbd_dev->lock_dwork)
Then when we reach the rbd_dev_free(), WARN_ON is triggered because
lock_state is not RBD_LOCK_STATE_UNLOCKED.
To fix it, this commit make sure the lock_dwork was finished before
calling rbd_dev_image_unlock().
On the other hand, this would not happend in do_rbd_remove(), because
after rbd mapped, lock_dwork will only be queued for IO request, and
request will continue unless lock_dwork finished. when we call
rbd_dev_image_unlock() in do_rbd_remove(), all requests are done.
That means, lock_state should not be locked again after
rbd_dev_image_unlock().
[ Cancel lock_dwork in rbd_add_acquire_lock(), only if the wait is
interrupted. ]

Before reading the Extended Size field, we should ensure it fits in
the DMI record. There is already a record length check but it does
not cover that field.
It would take a seriously corrupted DMI table to hit that bug, so no
need to worry, but we should still fix it.

Pull irqchip fixes from Marc Zyngier:
- Add retrigger support to Amazon's al-fic driver
- Add SAM9X60 support to Atmel's AIC5 irqchip
- Fix GICv3 maximum interrupt calculation
- Convert SiFive's PLIC to the fasteoi IRQ flow

Prevent simultaneous controller disabling/enabling tasks from interfering
with each other through a function to wait until the task successfully
transitioned the controller to the RESETTING state. This ensures disabling
the controller will not be interrupted by another reset path, otherwise
a concurrent reset may leave the controller in the wrong state.

A paused controller is doing critical internal activation work in the
background. Prevent subsequent controller resets from occurring during
this period by setting the controller state to RESETTING first. A helper
function, nvme_try_sched_reset_work(), is introduced for these paths so
they may continue with scheduling the reset_work after they've completed
their uninterruptible critical section.

A controller in the resetting state has not yet completed its recovery
actions. The pci and fc transports were already handling this, so update
the remaining transports to not attempt additional recovery in this
state. Instead, just restart the request timer.

The admin only state was intended to fence off actions that don't
apply to a non-IO capable controller. The only actual user of this is
the scan_work, and pci was the only transport to ever set this state.
The consequence of having this state is placing an additional burden on
every other action that applies to both live and admin only controllers.
Remove the admin only state and place the admin only burden on the only
place that actually cares: scan_work.
This also prepares to make it easier to temporarily pause a LIVE state
so that we don't need to remember which state the controller had been in
prior to the pause.

If a controller becomes degraded after a reset, we will not be able to
perform any IO. We currently teardown previously created request
queues and namespaces, but we had kept the unusable tagset. Free
it after all queues using it have been released.

Currently the exit return path when sme->key_idx >= NUM_WEPKEYS is via
label 'exit' and this checks if result is non-zero, however result has
not been initialized and contains garbage. Fix this by replacing the
goto with a return with the error code.

For APIC case of interrupt we don't fail a ->probe() of the driver,
which makes kernel to print a lot of warnings from the children.
We have two options here:
- switch to platform_get_irq_optional(), though it won't stop children
to be probed and failed
- fail the ->probe() of i2c-multi-instantiate
Since the in reality we never had devices in the wild where IRQ resource
is optional, the latter solution suits the best.
