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.

thread /proc/thread-self is derived from /proc/self. /proc/thread-self points to the directory in proc containing information about the current thread. This funtionality has been missing for a long time, and is tricky to implement in userspace as gettid() is not exported by glibc. More importantly this allows fixing defects in /proc/mounts and /proc/net where in a threaded application today they wind up being empty files when only the initial pthread has exited, causing problems for other threads.

2014-08-04NFS: Fix /proc/fs/nfsfs/servers and /proc/fs/nfsfs/volumesEric W. Biederman
The usage of pid_ns->child_reaper->nsproxy->net_ns in nfs_server_list_open and nfs_client_list_open is not safe. /proc for a pid namespace can remain mounted after the all of the process in that pid namespace have exited. There are also times before the initial process in a pid namespace has started or after the initial process in a pid namespace has exited where pid_ns->child_reaper can be NULL or stale. Making the idiom pid_ns->child_reaper->nsproxy a double whammy of problems. Luckily all that needs to happen is to move /proc/fs/nfsfs/servers and /proc/fs/nfsfs/volumes under /proc/net to /proc/net/nfsfs/servers and /proc/net/nfsfs/volumes and add a symlink from the original location, and to use seq_open_net as it has been designed.

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Updates for v3.17 This has been a pretty exciting release in terms of the framework, we've finally got support for multiple CODECs attached to a single DAI link which has been something there's been interest in as long as I've been working on ASoC. A big thanks to Benoit and Misael for their work on this. Otherwise it's been a fairly standard release for development, including more componentisation work from Lars-Peter and a good selection of both CODEC and CPU drivers. - Support for multiple CODECs attached to a single DAI, enabling systems with for example multiple DAC/speaker drivers on a single link, contributed by Benoit Cousson based on work from Misael Lopez Cruz. - Support for byte controls larger than 256 bytes based on the use of TLVs contributed by Omair Mohammed Abdullah. - More componentisation work from Lars-Peter Clausen. - The remainder of the conversions of CODEC drivers to params_width() - Drivers for Cirrus Logic CS4265, Freescale i.MX ASRC blocks, Realtek RT286 and RT5670, Rockchip RK3xxx I2S controllers and Texas Instruments TAS2552. - Lots of updates and fixes, especially to the DaVinci, Intel, Freescale, Realtek, and rcar drivers.

2014-08-04drm/msm/mdp5: add support for MDP5 v1.3Stephane Viau
MDP5 has several functional blocks (ie: VIG/RGB pipes, LMs, ...). From one revision to another, these blocks' base addresses might change due to the number of instances present in the MDP5 hw. A way of dealing with these offset changes is to introduce dynamic offsets 'per block'. This change adds support for the new revision of MDP5: v1.3. The idea is to define one hw config per MDP version and select either one of them at runtime, after reading the MDP5 version. Once the MDP version is known, 'per block' dynamic offsets are initialized through a global pointer, which is then used for read/write register access.

2014-08-04drm/msm: use upstream iommuRob Clark
Downstream kernel IOMMU had a non-standard way of dealing with multiple devices and multiple ports/contexts. We don't need that on upstream kernel, so rip out the crazy. Note that we have to move the pinning of the ringbuffer to after the IOMMU is attached. No idea how that managed to work properly on the downstream kernel. For now, I am leaving the IOMMU port name stuff in place, to simplify things for folks trying to backport latest drm/msm to device kernels. Once we no longer have to care about pre-DT kernels, we can drop this and instead backport upstream IOMMU driver. Signed-off-by: Rob Clark <robdclark@gmail.com>
