14667a4bde drm/i915: Finish any pending operations on the framebuffer before disabling
Similar to the case where we are changing from one framebuffer to
another, we need to be sure that there are no pending WAIT_FOR_EVENTs on
the pipe for the current framebuffer before switching. If we disable the
pipe, and then try to execute a WAIT_FOR_EVENT it will block
indefinitely and cause a GPU hang.

We attempted to fix this in commit 85345517fe6d4de27b0d6ca19fef9d28ac947c4a
(drm/i915: Retire any pending operations on the old scanout when switching)
for the case of mode switching, but this leaves the condition where we
are switching off the pipe vulnerable.

There still remains the race condition were a display may be unplugged,
switched off by the core, a uevent sent to notify the DDX and the DDX
may issue a WAIT_FOR_EVENT before it processes the uevent. This window
does not exist if the pipe is only switched off in response to the
uevent. Time to make sure that is so...

bc02d15a34 serial/8250_pci: add a "force background timer" flag and use it for the "kt" serial port
Workaround dropped notifications in the iir register.  Register reads
coincident with new interrupt notifications sometimes result in this
device clearing the interrupt event without reporting it in the read
data.

The serial core already has a heuristic for determining when a device
has an untrustworthy iir register.  In this case when we apriori know
that the iir is faulty use a flag (UPF_BUG_THRE) to bypass the test and
force usage of the background timer.

49b532f96f Revert "serial/8250_pci: setup-quirk workaround for the kt serial controller"
This reverts commit 448ac154c957c4580531fa0c8f2045816fe2f0e7.

The semantic of UPF_IIR_ONCE is only guaranteed to workaround the race
condition in the kt serial's iir register if the only source of
interrupts is THRE (fifo-empty) events.  An modem status event at the
wrong time can again cause an iir read to drop the 'empty' status
leading to a hang.  So, revert this in preparation for using the
existing "I don't trust my iir register" workaround in the 8250 core
(UART_BUG_THRE).

3579812373 Revert "serial/8250_pci: init-quirk msi support for kt serial controller"
This reverts commit e86ff4a63c9fdd875ba8492577cd1ad2252f525c.

This tried to enforce the semantics of one interrupt per iir read of the
THRE (transmit-hold empty) status, but events from other sources
(particularly modem status) defeat this guarantee.

This change also broke 8250_pci suspend/resume support as
pciserial_resume_ports() re-runs .init() quirks, but does not run
.exit() quirks in pciserial_suspend_ports() leading to reports like:

  sysfs: cannot create duplicate filename '/devices/pci0000:00/0000:00:16.3/msi_irqs'

...and a subsequent crash.  The mismatch of init/exit at suspend/resume
seems like a bug in its own right.

57c3686842 tty/serial: atmel_serial: fix RS485 half-duplex problem
On our custom board, we are using RS485 in half-duplex mode on an AT91SAM9G45.
SER_RS485_RX_DURING_TX is not set as we do not want to receive the data we
transmit (our transceiver will receive transmitted data).
Although the current driver attempts to disable and enable the receiver at the
appropriate points, incoming data is still loaded into the receive register
causing our code to receive the very last byte that was sent once the receiver
is enabled.

I ran this by Atmel support and they wrote: "The issue comes from the fact
that you disable the PDC/DMA Reception and not the USART Reception channel. In
your case, the[n] you will still receive data into the USART_RHR register, and
maybe you [h]ave the overrun flag set. So please disable the USART reception
channel."

The following patch should force the driver to enable/disable the receiver via
RXEN/RXDIS fields of the USART control register. It fixed the issue I was
having.

ed0ee0ce0a [media] uvcvideo: Fix race-related crash in uvc_video_clock_update()
The driver frees the clock samples buffer before stopping the video
buffers queue. If a DQBUF call arrives in-between,
uvc_video_clock_update() will be called with a NULL clock samples
buffer, leading to a crash. This occurs very frequently when using the
webcam with the flash browser plugin.

Move clock initialization/cleanup to uvc_video_enable() in order to free
the clock samples buffer after the queue is stopped. Make sure the clock
is reset at resume time to avoid miscalculating timestamps.

4da2876614 [media] it913x: fix firmware loading errors
On some systems the device does not respond or give obscure values after cold,
warm or firmware reboot.

This patch retries to get chip version and type 5 times. If it
fails it applies chip version 0x1 and type 0x9135.

This patch does not fix warm cycle problems from other operating
systems and indeed the reverse applies. Users should power off cold boot.

bc169e35e3 [media] ivtv: Fix AUDIO_(BILINGUAL_)CHANNEL_SELECT regression
When I converted ivtv to the new decoder API I introduced a regression in the
support of the old channel select API.

Thanks to Martin Dauskardt for reporting this.

556a0442e0 [media] dvb_frontend: regression fix: userspace ABI broken for xine
The commit e399ce77e6e has broken the DVB ABI for xine:

The problem is that xine is expecting every event after a successful
FE_SET_FRONTEND ioctl to have a non-zero frequency parameter, regardless
of whether the tuning process has LOCKed yet. What used to happen is
that the events inherited the initial tuning parameters from the
FE_SET_FRONTEND call. However, the fepriv->parameters_out struct is now
not initialised until the status contains the FE_HAS_LOCK bit.

You might argue that this behaviour is intentional, except that if an
application other than xine uses the DVB adapter and manages to set the
parameters_out.frequency field to something other than zero, then xine
no longer has any problems until either the adapter is replugged or the
kernel modules reloaded. This can only mean that the
fepriv->parameters_out struct still contains the (stale) tuning
information from the previous application.

640946f203 dentry leak in simple_fill_super() failure exit
d_genocide() does _not_ evict dentries; it just removes extra ref
pinning each of those.  Normally it's followed by shrinking the
tree (it's done just before generic_shutdown_super() by kill_litter_super()),
but in case of simple_fill_super() nothing of that kind will follow.
Just do shrink_dcache_parent() manually.

f4e52e7ffd regmap: A couple of small fixes for 3.4
Two more small fixes:
 - Now we have users for it that aren't running Android it turns out that
   regcache_sync_region() is much more useful to drivers if it's exported
   for use by modules.  Who knew?
 - Make sure we don't divide by zero when doing debugfs dumps of rbtrees,
   not visible up until now because everything was providing at least
   some cache on startup.
