2014-05-22mmc: sdhci: track whether preset mode is currently enabled in hardwareRussell King
Track whether preset mode is currently enabled in hardware, and use that when making decisions elsewhere in the code rather than reading the register and checking the bit.

2014-05-22mmc: sdhci: cache timing information locallyRussell King
Rather than reading back the timing information from the registers, cache it locally. This allows implementations to translate the UHS timing by overriding the set_uhs_signaling() method as required without also having to emulate the SDHCI_HOST_CONTROL2 register.

2014-05-22mmc: sdhci: convert to new SDIO IRQ handlingRussell King
Use a generic threaded interrupt handler for SDIO interrupt handling, rather than allowing the SDIO core code to buggily spawn its own thread. This results in host drivers to be more in control of how SDIO interrupts are acknowledged in the hardware, rather than having the internals of the SDIO core placed upon them, possibly resulting in sub-standard handling. At least one SDHCI implementation specifies a very specific sequence to deal with a card interrupt.

2014-05-22mmc: sdio_irq: rework sdio irq handlingRussell King
Rather than the SDIO support spawning it's own thread for handling card interrupts, use the generic IRQ infrastructure for this, triggering it from the host interface's interrupt handling directly. This avoids a race between the parent thread waiting to receive an interrupt response from the card, and the slow startup from the sdio irq thread, which can occur as a result of high system load (eg, while udev is running.)

The following parameters are no longer needed by the edma driver since the information can be obtained from the IP's CCCFG register: n_channel, n_region, n_slot and n_tc. Remove the n_cc as well since in this context it has no meaning. We have separate edma_soc_info struct/eDMA3_CC instance so this member does not make any sense (and the driver no longer uses it).

2014-05-22cfg80211: allow RSSI compensationEmmanuel Grumbach
Channels in 2.4GHz band overlap, this means that if we send a probe request on channel 1 and then move to channel 2, we will hear the probe response on channel 2. In this case, the RSSI will be lower than if we had heard it on the channel on which it was sent (1 in this case). The firmware / low level driver can parse the channel in the DS IE or HT IE and compensate the RSSI so that it will still have a valid value even if we heard the frame on an adjacent channel. This can be done up to a certain offset. Add this offset as a configuration for the low level driver. A low level driver that can compensate the low RSSI in this case should assign the maximal offset for which the RSSI value is still valid.

2014-05-21net: filter: cleanup invocation of internal BPFAlexei Starovoitov
Kernel API for classic BPF socket filters is: sk_unattached_filter_create() - validate classic BPF, convert, JIT SK_RUN_FILTER() - run it sk_unattached_filter_destroy() - destroy socket filter Cleanup internal BPF kernel API as following: sk_filter_select_runtime() - final step of internal BPF creation. Try to JIT internal BPF program, if JIT is not available select interpreter SK_RUN_FILTER() - run it sk_filter_free() - free internal BPF program Disallow direct calls to BPF interpreter. Execution of the BPF program should be done with SK_RUN_FILTER() macro. Example of internal BPF create, run, destroy: struct sk_filter *fp; fp = kzalloc(sk_filter_size(prog_len), GFP_KERNEL); memcpy(fp->insni, prog, prog_len * sizeof(fp->insni[0])); fp->len = prog_len; sk_filter_select_runtime(fp); SK_RUN_FILTER(fp, ctx); sk_filter_free(fp); Sockets, seccomp, testsuite, tracing are using different ways to populate sk_filter, so first steps of program creation are not common.

2014-05-21crypto: hash - Add real ahash walk interfaceHerbert Xu
Although the existing hash walk interface has already been used by a number of ahash crypto drivers, it turns out that none of them were really asynchronous. They were all essentially polling for completion. That's why nobody has noticed until now that the walk interface couldn't work with a real asynchronous driver since the memory is mapped using kmap_atomic. As we now have a use-case for a real ahash implementation on x86, this patch creates a minimal ahash walk interface. Basically it just calls kmap instead of kmap_atomic and does away with the crypto_yield call. Real ahash crypto drivers don't need to yield since by definition they won't be hogging the CPU.

2014-05-21mfd: bcm590xx: Add support for secondary I2C slave addressMatt Porter
BCM590xx utilizes a secondary I2C slave address to access additional register space. Add support for the secondary address space by instantiating a dummy I2C device with the appropriate secondary I2C slave address. Also expose a secondary regmap register space so that MFD drivers can access this secondary i2c slave address space.

git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup Pull more cgroup fixes from Tejun Heo: "Three more patches to fix cgroup_freezer breakage due to the recent cgroup internal locking changes - an operation cgroup_freezer was using now requires sleepable context and cgroup_freezer was invoking that while holding a spin lock. cgroup_freezer was using an overly elaborate hierarchical locking scheme. While it's possible to convert the hierarchical spinlocks directly to mutexes, this patch simplifies the overall locking so that it uses a global mutex. This has the added benefit of avoiding iterating potentially huge number of tasks under a spinlock. While the patch is on the larger side in the devel cycle, the changes made are mostly straight-forward and the locking logic is a lot simpler afterwards" * 'for-3.15-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup: cgroup: fix rcu_read_lock() leak in update_if_frozen() cgroup_freezer: replace freezer->lock with freezer_mutex cgroup: introduce task_css_is_root()
2014-05-21drm/irq: Add kms-native crtc interface functionsDaniel Vetter
We need to start somewhere ... With this the only places left in i915 where we use pipe integers is in the interrupt handling code. And there it actually makes some amount of sense. v2: - Polish kerneldoc a bit (Thierry). - Drop "dev" parameter since it's unecessary. - Split out i915 changes (Thierry).
