Pull clock framework updates from Mike Turquette:
 "The clock framework changes for 3.17 are mostly additions of new clock
  drivers and fixes/enhancements to existing clock drivers.  There are
  also some non-critical fixes and improvements to the framework core.

  Changes to the clock framework core include:
   - improvements to printks on errors
   - flattening the previously hierarchal structure of per-clock entries
     in debugfs
   - allow per-clock debugfs entries that are specific to a particular
     clock driver
   - configure initial clock parent and/or initial clock rate from
     Device Tree
   - several feature enhancements to the composite clock type
   - misc fixes

  New clock drivers added include:
   - TI Palmas PMIC
   - Allwinner A23 SoC
   - Qualcomm APQ8084 and IPQ8064 SoCs
   - Rockchip rk3188, rk3066 and rk3288 SoCs
   - STMicroelectronics STiH407 SoC
   - Cirrus Logic CLPS711X SoC

  Many fixes, feature enhancements and further clock tree support for
  existing clock drivers also were merged, such as Samsung's "ARMCLK
  down" power saving feature for their Exynos4 & Exynos5 SoCs"

Pull cgroup changes from Tejun Heo:
 "Mostly changes to get the v2 interface ready.  The core features are
  mostly ready now and I think it's reasonable to expect to drop the
  devel mask in one or two devel cycles at least for a subset of
  controllers.

   - cgroup added a controller dependency mechanism so that block cgroup
     can depend on memory cgroup.  This will be used to finally support
     IO provisioning on the writeback traffic, which is currently being
     implemented.

   - The v2 interface now uses a separate table so that the interface
     files for the new interface are explicitly declared in one place.
     Each controller will explicitly review and add the files for the
     new interface.

   - cpuset is getting ready for the hierarchical behavior which is in
     the similar style with other controllers so that an ancestor's
     configuration change doesn't change the descendants' configurations
     irreversibly and processes aren't silently migrated when a CPU or
     node goes down.

nr_dirty is updated without locking, causing it to drift so that it is
non-zero (either a small positive integer, or a very large one when an
underflow occurs) even when there are no actual dirty blocks.  This was
due to a race between the workqueue and map function accessing nr_dirty
in parallel without proper protection.

People were seeing under runs due to a race on increment/decrement of
nr_dirty, see: https://lkml.org/lkml/2014/6/3/648

Fix this by using an atomic_t for nr_dirty.

1d3d4437 ("vmscan: per-node deferred work") added a flags field to
struct shrinker assuming that all shrinkers were zero filled.  The dm
bufio shrinker is not zero filled, which leaves arbitrary kmalloc() data
in flags.  So far the only defined flags bit is SHRINKER_NUMA_AWARE.
But there are proposed patches which add other bits to shrinker.flags
(e.g. memcg awareness).

Rather than simply initializing the shrinker, this patch uses kzalloc()
when allocating the dm_bufio_client to ensure that the embedded shrinker
and any other similar structures are zeroed.

This fixes theoretical over aggressive shrinking of dm bufio objects.
If the uninitialized dm_bufio_client.shrinker.flags contains
SHRINKER_NUMA_AWARE then shrink_slab() would call the dm shrinker for
each numa node rather than just once.  This has been broken since 3.12.
