In commit e3de42b68478a8c95dd27520e9adead2af9477a5
Author: Imre Deak <imre.deak@intel.com>

drm/i915: force full modeset if the connector is in DPMS OFF mode
a new function was added that walked over the set of connectors to see
if any of the currently associated CRTC was switched off. This function
walked an array of connectors, rather than the array of pointers to
connectors contained in the drm_mode_set - i.e. it was dereferencing far
past the end of the first connector. This only becomes an issue if we
attempt to use a clone mode (i.e. more than one connector per CRTC) such
that set->num_connectors > 1.

There seems to be no limit to the amount of gunk the firmware can
leave behind. Some platforms leave pch dplls on which are not in
active use at all. The example in the bug report is a Apple Macbook
Pro.
Note that this escape scrunity of the hw state checker until we've
tried to use this enabled, but unused pll since we did only check for
the inverse case of a in-used, but disabled pll.
v2: Add a WARN in the pll state checker which would have caught this
case.

We've got bug reports that the module loading stuck on Debian system
with 3.10 kernel. The debugging session revealed that the initial
registration of OSS sequencer clients stuck at module loading time,
which involves again with request_module() at the init phase. This is
triggered only by special --install stuff Debian is using, but it's
still not good to have such loops.
As a workaround, call the registration part asynchronously. This is a
better approach irrespective of the hang fix, in anyway.

This patch fixes regression in power consumtion of sandy bridge gpu, which
exists since v3.6 Sometimes after resuming from s2ram gpu starts thinking that
it's extremely busy. After that it never reaches rc6 state.
Bug exists since kernel v3.6:
commit b4ae3f22d238617ca11610b29fde16cf8c0bc6e0
Author: Jesse Barnes <jbarnes@virtuousgeek.org>
Date: Thu Jun 14 11:04:48 2012 -0700
drm/i915: load boot context at driver init time
For some reason RC6 is already enabled at the beginning of resuming process.
Following initliaztion breaks some internal state and confuses RPS engine.
This patch disables RC6 at the beginnig of resume and initialization.
I've rearranged initialization sequence, because intel_disable_gt_powersave()
needs initialized force_wake_get/put and some locks from the dev_priv.
Note: The culprit in the initialization sequence seems to be the write
to MBCTL added in the above mentioned commit. The first version of
this patch just held a forcewake reference across the clock gating
init functions, which seems to have been enought to gather quite a few
positive test reports. But since that smelled a bit like ad-hoc
duct-tape v2 now just disables rps/rc6 across the entire hw setup.

As we hot-add 128 MB chunks of memory, we wait to ensure that the memory
is onlined before attempting to hot-add the next chunk. If the udev rule for
memory hot-add is not executed within the allowed time, we would rollback the
state and abort further hot-add. Since the hot-add has succeeded and the only
failure is that the memory is not onlined within the allowed time, we should not
be rolling back the state. Fix this bug.

unregistered
Whenever a device is unregistered in vmbus_device_unregister (drivers/hv/vmbus_drv.c), the device name in the log message may contain garbage as the memory has already been freed by the time pr_info is called. Log example:
[ 3149.170475] hv_vmbus: child device àõsèè0_5 unregistered
By logging the message just before calling device_unregister, the correct device name is printed:
[ 3145.034652] hv_vmbus: child device vmbus_0_5 unregistered
Also changing register & unregister messages to debug to avoid unnecessarily cluttering the kernel log.

The first round of IIO fixes for the 3.11 cycle.
This set is larger than I would like, partly due to my lack of review
time in the weeks before the merge window and partly because a
couple of large drivers and the subsystem as a whole seem to be
getting a lot more exposure and testing recently.
1) A long term bug in trigger handling gave a double free of the device.
2) Wrong return value handling means offsets are ignored in
iio_convert_raw_to_processed_unlocked.
3) The iio_channel_has_info utility function was incorrectly updated
during the recent info_mask split, this is now fixed.
4) mxs-lradc has a couple of little fixes.
5) A couple of missing .driver_module entries meant that drivers
could be removed from underneath their users.
6) Error path fixes for ad7303 and lis3l02dq.
7) The scale value for presure in the lps331ap driver was out by
a factor of 100.

This driver is not being updated as the specifications are not able to
be gotten from CSR or anyone else. Without those, getting this driver
into proper mergable shape is going to be impossible. So remove the
driver from the tree.
If the specifications ever become available, this patch can be reverted
and the driver fixed up properly.

__list_for_each used to be the non prefetch() aware list walking
primitive. When we removed the prefetch macros from the list routines,
it became redundant. Given it does exactly the same thing as
list_for_each now, we might as well remove it and call list_for_each
directly.
All users of __list_for_each have been converted to list_for_each calls
in the current merge window.
