Pull ext4 updates from Ted Ts'o: "New features for 3.12: - Added aggressive extent caching using the extent status tree. This can actually decrease memory usage in read-mostly workloads since the information is much more compactly stored in the extent status tree than if we had to keep the extent tree metadata blocks in the buffer cache. This also improves Asynchronous I/O since it is it makes much less likely that we need to do metadata I/O to lookup the extent tree information. - Improve the recovery after corrupted allocation bitmaps are found when running in errors=ignore mode.

Pull pin control changes from Linus Walleij: "Here is the bulk of pin control changes for the v3.12 series. Most of the relevant information is in the tag. I merged in v3.11-rc7 last week to get rid of a largeish conflict within the sunxi (AllWinner) driver in linux-next and fix up the non-trivial merge the right way. That driver had a rather large fix adding locking late in the release cycle. Overall the bulk changes this time is cleanups and refactorings and not much new features, which is nice. - Refactorings for generic pin config handling in the core. - Factor out a set of device tree utilities for use in all drivers, to parse and allocate maps from the device tree. - Some fixes to the core such as more nitpicky locking. - Pushed down config array iteration into the drivers. This patch is necessary for drivers that want to iterate over configs and pile up a stack of alterations to the same register(s), or if the driver wants to take a local spinlock when committing the configuration. - A new driver for the Texas Instruments Palmas PMIC by Laxman Dewangan. This is used on the Tegra systems. - A major cleanup and modernization of the PFC (Super Hitachi and ARM SHmobile) pin controller and subdrivers. - Support for the A20 and A31 sunxi (AllWinner) SoCs. - A huge pile of fixes and cleanups: Axel Lin, Jingoo Han Dan Carpenter, Julia Lawall and Sachin Kamat did an excellent job here" * tag 'pinctrl-v3.12-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (124 commits) pinctrl: sunxi: Fix off-by-one for valid offset range checking pinctrl: sunxi: drop lock on error path pinctrl: pinconf-generic: Remove ti prefix in dev_err messages pinctrl: rockchip: Implement .request() and .free() callbacks pinctrl: at91: fix get_pullup/down function return pinctrl: sh-pfc: remove unnecessary platform_set_drvdata() pinctrl: Add s5pv210 support to pinctrl-exynos pinctrl: utils: include export.h to avoid warnings pinctrl: s3c24xx: off by one in s3c24xx_eint_init() pinctrl: mvebu: testing the wrong variable pinctrl: abx500: fix bitwise AND test pinctrl: mvebu: Convert to use devm_ioremap_resource pinctrl: Pass all configs to driver on pin_config_set() pinctrl: tz1090-pdc: Convert to devm_ioremap_resource pinctrl: tz1090: Convert to devm_ioremap_resource pinctrl: tegra: Convert to devm_ioremap_resource pinctrl: rockchip: Simplify pin_to_bank equation pinctrl: spear: Convert to devm_ioremap_resource pinctrl: rockchip: Remove of_match_ptr macro for DT only driver pinctrl: palmas: PINCTRL_PALMAS needs to select PINMUX ...

Pull cgroup updates from Tejun Heo: "A lot of activities on the cgroup front. Most changes aren't visible to userland at all at this point and are laying foundation for the planned unified hierarchy. - The biggest change is decoupling the lifetime management of css (cgroup_subsys_state) from that of cgroup's. Because controllers (cpu, memory, block and so on) will need to be dynamically enabled and disabled, css which is the association point between a cgroup and a controller may come and go dynamically across the lifetime of a cgroup. Till now, css's were created when the associated cgroup was created and stayed till the cgroup got destroyed. Assumptions around this tight coupling permeated through cgroup core and controllers. These assumptions are gradually removed, which consists bulk of patches, and css destruction path is completely decoupled from cgroup destruction path. Note that decoupling of creation path is relatively easy on top of these changes and the patchset is pending for the next window. - cgroup has its own event mechanism cgroup.event_control, which is only used by memcg. It is overly complex trying to achieve high flexibility whose benefits seem dubious at best. Going forward, new events will simply generate file modified event and the existing mechanism is being made specific to memcg.
