Atm, the HPD IRQ reenable timer can get rearmed right after it's
canceled. Also to access the HPD IRQ mask registers we need to wake up
the HW.
Solve both issues by converting the reenable timer to a delayed work and
grabbing a runtime PM reference in the work. By this we can also forgo
canceling the timer during runtime suspend, since the only important
thing there is that the HW is awake when we write the registers and
that's ensured by the RPM ref. So do the cancelation only during driver
unload time; this is also a requirement for an upcoming patch where we
want to cancel all HPD related works only during system suspend and
driver unload time, but not during runtime suspend.
Note that there is still a race between the HPD IRQ reenable work and
drm_irq_uninstall() during driver unload, where the work can reenable
the HPD IRQs disabled by drm_irq_uninstall(). This isn't a problem since
the HPD IRQs will still be effectively masked by the first level
interrupt mask.

If pwm_get() finds a look-up entry with a perfect match (both dev_id and

If only an entry with a matching dev_id or con_id is found, the loop

Then pwm_set_period() and pwm_set_polarity() will set random values for

During suspend we turn off the crtcs, but leave the staged config in
place so that we can restore the display(s) to their previous state on
resume.
During resume when we attempt to apply the force pipe A quirk we use the
load detect mechanism. That doesn't check whether there was an already
staged configuration for the crtc since that's not even possible during
normal runtime load detection. But during resume it is possible, and if
we just blindly go and overwrite the staged crtc configuration for the
load detection we can no longer restore the display to the correct
state.
Even worse, we don't even clear all the staged connector->encoder->crtc
links so we may end up using a cloned setup for the load detection, and
after we're done we just clear the links related to the VGA output
leaving the links for the other outputs in place. This will eventually
result in calling intel_set_mode() with mode==NULL but with valid
connector->encoder->crtc links which will result in dereferencing the
NULL mode since the code thinks it will have to a modeset.
To avoid these problems don't use any crtc with new_enabled==true for
load detection.

During recovery of a double-degraded RAID6 it is possible for
some blocks not to be recovered properly, leading to corruption.
If a write happens to one block in a stripe that would be written to a
missing device, and at the same time that stripe is recovering data
to the other missing device, then that recovered data may not be written.
This patch skips, in the double-degraded case, an optimisation that is
only safe for single-degraded arrays.
Bug was introduced in 2.6.32 and fix is suitable for any kernel since
then. In an older kernel with separate handle_stripe5() and

If a stripe in a raid6 array received a write to each data block while
the array is degraded, and if any of these writes to a missing device
are not page-aligned, then a live-lock happens.
In this case the P and Q blocks need to be read so that the part of
the missing block which is *not* being updated by the write can be
constructed. Due to a logic error, these blocks are not loaded, so
the update cannot proceed and the stripe is 'handled' repeatedly in an
infinite loop.
This bug is unlikely as most writes are page aligned. However as it
can lead to a livelock it is suitable for -stable. It was introduced
in 3.16.

After the suspend routine running in OCRAM puts DDR into self-refresh,
it will access IOMUXC block to float DDR IO for power saving. A TLB
missing of IOMUXC base address may happen in this case, and triggers an
access to DDR, and thus hangs the system.
The failure is discovered by running suspend/resume on a Cubox-i board.
Though the issue is not Cubox-i specific, it can be hit the on the board
quite easily with the 3.15 or 3.16 kernel.
Fix the issue with a dummy access to IOMUXC block at the beginning of
suspend routine, so that the address translation can be filled into TLB

The Zynq GPIO interrupt handling code as two main issues:
1) It does not support IRQF_ONESHOT interrupt since it uses handle_simple_irq()
for the interrupt handler. handle_simple_irq() does not do masking and unmasking
of the IRQ that is required for this chip to be able to support IRQF_ONESHOT
IRQs, causing the CPU to lock up in a interrupt storm if such a interrupt is
requested.
2) Interrupts are acked after the primary interrupt handlers for all asserted
interrupts in a bank have been called. For edge triggered interrupt this is to
late and may cause a interrupt to be missed. For level triggered oneshot
interrupts this is to early and causes the interrupt handler to run twice per
interrupt.
This patch addresses the issue by updating the driver to use the correct IRQ
chip handler functions that are appropriate for this kind of IRQ controller.
The following diagram gives an overview of how the interrupt detection circuit
works, it is not necessarily a accurate depiction of the real hardware though.

INT_POL
GPIO_IN is the raw signal level connected to the hardware pin. This signal is
routed to a edge detector and to a level detector. The edge detector can be
configured to either detect a rising or falling edge or both edges. The level
detector can detect either a level high or level low event. Depending on the
setting of the INT_TYPE register either the edge or level event will be
propagated to the INT_STATUS register. As long as a interrupt condition is
detected the INT_STATUS register will be set to 1. It can be cleared to 0 if
(and only if) the interrupt condition is no longer detected and software
acknowledges the interrupt by writing a 1 to the address of the INT_STATUS
register. There is also the INT_MASK register which can be used to disable the
propagation of the INT_STATUS signal to the upstream IRQ controller. What is
important to note is that the interrupt detection logic itself can not be
disabled, only the propagation of the INT_STATUS register can be delayed. This
means that for level type interrupts the interrupt must only be acknowledged
after the interrupt source has been cleared otherwise it will stay asserted and
the interrupt handler will be run a second time. For IRQF_ONESHOT interrupts
this means that the IRQ must only be acknowledged after the threaded interrupt
has finished running. If a second interrupt comes in between handling the first
interrupt and acknowledging it the external interrupt will be asserted, which
means trying to acknowledge the first interrupt will not clear the INT_STATUS
register and the interrupt handler will be run a second time when the IRQ is
unmasked, so no interrupts will be lost. The handle_fasteoi_irq() handler in
combination with the IRQCHIP_EOI_THREADED | IRQCHIP_EOI_IF_HANDLED flags will
have the desired behavior. For edge triggered interrupts a slightly different
strategy is necessary. For edge triggered interrupts the interrupt condition is
only true when the edge itself is detected, this means this is the only time the
INT_STATUS register is set, acknowledging the interrupt any time after that will
clear the INT_STATUS register until the next interrupt happens. This means in
order to not loose any interrupts the interrupt needs to be acknowledged before
running the interrupt handler. If a second interrupt occurs after the first
interrupt handler has finished but before the interrupt is unmasked the
INT_STATUS register will be re-asserted and the interrupt handler runs a second
time once the interrupt is unmasked. This means with this flow handling strategy
no interrupts are lost for edge triggered interrupts. The handle_level_irq()
handler will have the desired behavior. (Note: The handle_edge_irq() only needs
to be used for edge triggered interrupts where the controller stops detecting
the interrupt event when the interrupt is masked, for this controller the
detection logic still works, while only the propagation is delayed when the
interrupt is masked.)

Pull x86 platform driver updates from Matthew Garrett:
"A moderate number of changes, but nothing awfully significant.
A lot of const cleanups, some reworking and additions to the rfkill
quirks in the asus driver, a new driver for generating falling laptop
events on Toshibas and some misc fixes.
Maybe vendors have stopped inventing things"

The biggest of the bunch is Mark's quota fix, which is also in the

Merge tag 'locks-v3.17-2' of git://git.samba.org/jlayton/linux
Pull file locking bugfixes from Jeff Layton:
"Most of these patches are to fix a long-standing regression that crept
in when the BKL was removed from the file-locking code. The code was
converted to use a conventional spinlock, but some fl_release_private
ops can block and you can end up sleeping inside the lock.
There's also a patch to make /proc/locks show delegations as 'DELEG'"
* tag 'locks-v3.17-2' of git://git.samba.org/jlayton/linux:
locks: update Locking documentation to clarify fl_release_private behavior
locks: move locks_free_lock calls in do_fcntl_add_lease outside spinlock
locks: defer freeing locks in locks_delete_lock until after i_lock has been dropped
locks: don't reuse file_lock in __posix_lock_file
locks: don't call locks_release_private from locks_copy_lock
locks: show delegations as "DELEG" in /proc/locks
