589c603b2c clk: exynos5250: Add sclk_mpll to the parent list of mout_cpu clock
'mout_mpll' is added the list of parent clocks for 'mout_cpu'.
'mout_mpll' is an alias to the clock 'sclk_mpll'. Hence 'sclk_mpll'
should be added to the list of parent clocks.

This results in an error when cpufreq driver for EXYNOS5250 tries to
set 'mout_mpll' as a parent for 'mout_cpu'.

clk_set_parent: clk sclk_mpll can not be parent of clk mout_cpu

39b72d89eb clk: exynos5250: Update cpufreq related clocks for EXYNOS5250
cpufreq driver for EXYNOS5250 is not a platform driver, hence we cannot
currently pass the clock names through a device tree node. Instead, we
need to make them available through a global alias.

cpufreq driver for EXYNOS5250 requires four clocks - 'armclk',
'mout_cpu', 'mout_mpll' and 'mout_apll'.

'armclk' has already been defined with an alias, 'mout_cpu', 'mout_mpll'
and 'mout_apll' are now defined with an alias.

92bb73ea2c tuntap: fix a possible race between queue selection and changing queues
Complier may generate codes that re-read the tun->numqueues during
tun_select_queue(). This may be a race if vlan->numqueues were changed in the
same time and can lead unexpected result (e.g. very huge value).

We need prevent the compiler from generating such codes by adding an
ACCESS_ONCE() to make sure tun->numqueues were only read once.

Bug were introduced by commit c8d68e6be1c3b242f1c598595830890b65cea64a
(tuntap: multiqueue support).

6c6cf64b16 spi: s3c64xx: Fix pm_runtime_get_sync() return value check
If the device is already in a runtime PM enabled state
pm_runtime_get_sync() will return 1, so a test for negative
value should be used to check for errors.

Without this patch there are seen errors like:

[    8.540000] s3c64xx-spi 13930000.spi: Failed to enable device: 1
[    8.545000] spi_master spi1: failed to prepare transfer hardware

Likely because the driver uses synchronous API to runtime enable
the device and asynchronous one to disable it.

b2c75c446a xen/tmem: Don't over-write tmem_frontswap_poolid after tmem_frontswap_init set it.
Commit 10a7a0771399a57a297fca9615450dbb3f88081a ("xen: tmem: enable Xen
tmem shim to be built/loaded as a module") allows the tmem module
to be loaded any time. For this work the frontswap API had to
be able to asynchronously to call tmem_frontswap_init before
or after the swap image had been set. That was added in git
commit 905cd0e1bf9ffe82d6906a01fd974ea0f70be97a
("mm: frontswap: lazy initialization to allow tmem backends to build/run as modules").

Which means we could do this (The common case):

 modprobe tmem		[so calls frontswap_register_ops, no ->init]
			 modifies tmem_frontswap_poolid = -1
 swapon /dev/xvda1	[__frontswap_init, calls -> init, tmem_frontswap_poolid is
			 < 0 so tmem hypercall done]

Or the failing one:

 swapon /dev/xvda1	[calls __frontswap_init, sets the need_init bitmap]
 modprobe tmem		[calls frontswap_register_ops, -->init calls, finds out
			tmem_frontswap_poolid is 0, does not make a hypercall.
			Later in the module_init, sets tmem_frontswap_poolid=-1]

Which meant that in the failing case we would not call the hypercall
to initialize the pool and never be able to make any frontswap
backend calls.

Moving the frontswap_register_ops after setting the tmem_frontswap_poolid
fixes it.

8c9b7a7b2f ACPI / video: Do not bind to device objects with a scan handler
With the introduction of ACPI scan handlers, ACPI device objects
with an ACPI scan handler attached to them must not be bound to
by ACPI drivers any more.  Unfortunately, however, the ACPI video
driver attempts to do just that if there is a _ROM ACPI control
method defined under a device object with an ACPI scan handler.

Prevent that from happening by making the video driver's "add"
routine check if the device object already has an ACPI scan handler
attached to it and return an error code in that case.

That is not sufficient, though, because acpi_bus_driver_init() would
then clear the device object's driver_data that may be set by its
scan handler, so for the fix to work acpi_bus_driver_init() has to be
modified to leave driver_data as is on errors.

c3456fb3e4 drm/i915: prefer VBT modes for SVDO-LVDS over EDID
In

Author: Egbert Eich <eich@suse.de>
Date:   Tue Jun 4 17:13:21 2013 +0200

    drm/i915/sdvo: Use &intel_sdvo->ddc instead of intel_sdvo->i2c for DDC

Egbert Eich fixed a long-standing bug where we simply used a
non-working i2c controller to read the EDID for SDVO-LVDS panels.
Unfortunately some machines seem to not be able to cope with the mode
provided in the EDID. Specifically they seem to not be able to cope
with a 4x pixel mutliplier instead of a 2x one, which seems to have
been worked around by slightly changing the panels native mode in the
VBT so that the dotclock is just barely above 50MHz.

Since it took forever to notice the breakage it's fairly safe to
assume that at least for SDVO-LVDS panels the VBT contains fairly sane
data. So just switch around the order and use VBT modes first.

v2: Also add EDID modes just in case, and spell Egbert correctly.

v3: Elaborate a bit more about what's going on on Chris' machine.

7ba220cec0 drm/i915: Enable hotplug interrupts after querying hw capabilities.
sdvo->hotplug_active is initialised during intel_sdvo_setup_outputs(),
and so we never enabled the hotplug interrupts on SDVO as we were
checking too early.

This regression has been introduced somewhere in the hpd rework for
the storm detection and handling starting with

    DRM/I915: Add enum hpd_pin to intel_encoder.

and the follow-up patches to use the new encoder->hpd_pin variable for
the different irq setup functions.

The problem is that encoder->hpd_pin was set up _before_ the output
setup was done and so before we could assess the hotplug capabilities
of the outputs on an sdvo encoder.

Fixing this will make the pin/unpin count match and prevent cursor
objects from leaking when userspace drops all references to it. Also
make sure we drop the gem obj reference on failure.

This patch only affects Cedarview chips.

22e7c385a8 drm/gma500/cdv: Unpin framebuffer on crtc disable
The framebuffer needs to be unpinned in the crtc->disable callback
because of previous pinning in psb_intel_pipe_set_base(). This will fix
a memory leak where the framebuffer was released but not unpinned

af44ad5edd [media] soc_camera: error dev remove and v4l2 call
in soc_camera_close(), if ici->ops->remove() removes device firstly,
and then call __soc_camera_power_off(), it has logic error. Since
if remove device, it should disable subdev clk. but in __soc_camera_
power_off(), it will callback v4l2 s_power function which will
read/write subdev registers to control power by i2c. and then
i2c read/write will fail because of clk disable.
So suggest to re-sequence two functions call.

609c4c12af [media] cx88: fix NULL pointer dereference
This fixes a NULL pointer deference when loading the cx88_dvb module for a
Hauppauge HVR4000.
The bugzilla bug report is here:
https://bugzilla.kernel.org/show_bug.cgi?id=56271
The cause is that the wm8775 is optional, so even though the board info says
there is one, it doesn't have to be there. Checking whether the module was
actually loaded is much safer.
Note that this driver is quite buggy when it comes to unloading and reloading
modules. Unloading cx8800 and reloading it again will still cause a crash,
most likely because either the i2c bus isn't unloaded at the right time and/or
the v4l2_device_unregister isn't called at the right time.

that this clock is always on, left in its default state after system

b4155d7d5b [media] exynos4-is: Ensure fimc-is clocks are not enabled until properly configured
Use clk_prepare_enable/clk_unprepare_disable instead of preparing the
clocks during the driver initalization and then using just clk_disable/
clk_enable. The clock framework doesn't guarantee a clock will not get
enabled during e.g. clk_set_parent if clk_prepare has been called on it.
So we ensure clk_prepare() is called only when it is safe to enable
the clocks, i.e. the parent clocks and the clocks' frequencies are set.
It must be ensured the FIMC-IS clocks have proper frequencies before they
are enabled, otherwise the whole system will hang.

rx2600.  Tony says:

  "It panics with the message:

   Kernel panic - not syncing: Unable to find SBA IOMMU: Try a generic or DIG kernel

   [...] my problem comes from arch/ia64/hp/common/sba_iommu.c
   where the code in sba_init() says:

        acpi_bus_register_driver(&acpi_sba_ioc_driver);
        if (!ioc_list) {

   but because of this change we never managed to call ioc_init()
   so ioc_list doesn't get set up, and we die."

Revert it to avoid this breakage and we'll fix the problem it attempted
to address later.

090878aa95 The mxs fixes for 3.10:
- Since the time we move to MULTI_IRQ_HANDLER, the 0x7f polling for no
   interrupt in icoll_handle_irq() becomes insane, because 0x7f is an
   valid interrupt number, the irq of gpio bank 0.  That unnecessary
   polling results in the driver not detecting when irq 0x7f is active
   which makes the machine effectively dead lock.  The fix removes the
   interrupt poll loop and allows usage of gpio0 interrupt without an
   infinite loop.

  interrupt in icoll_handle_irq() becomes insane, because 0x7f is an
  valid interrupt number, the irq of gpio bank 0.  That unnecessary
  polling results in the driver not detecting when irq 0x7f is active
  which makes the machine effectively dead lock.  The fix removes the
  interrupt poll loop and allows usage of gpio0 interrupt without an
  infinite loop.

fb565ff7c8 Renesas ARM based SoC fixes for v3.10
* Correction to USB OVC and PENC pin groupings on r8a7779 SoC.
   This avoids conflicts when the USB_OVCn pins are used by another function.
   This has been observed to be a problem in v3.10-rc1.
 
 * Update CMT clock rating for sh73a0 SoC to resolve boot failure
   on kzm9g-reference. This resolves a regression between v3.9 and v3.10-rc1.

On a system with both MAX1617 and JC42 sensors, JC42 sensors can be misdetected
as LM84. Strengthen detection sufficiently enough to avoid this misdetection.
Also improve detection for ADM1021.

7cd8407d53 ACPI / PM: Do not execute _PS0 for devices without _PSC during initialization
Commit b378549 (ACPI / PM: Do not power manage devices in unknown
initial states) added code to force devices without _PSC, but having
_PS0 defined in the ACPI namespace, into ACPI power state D0 by
executing _PS0 for them.  That turned out to break Toshiba P870-303,
however, so revert that code.
