Using HMAC version limits the posibility to arbitrarily add new attributes such as SMACK64EXEC to the hmac calculation. This patch replaces hmac version with attribute mask. Desired attributes can be enabled with configuration parameter. It allows to build kernels which works with previously labeled filesystems. Currently supported attribute is 'fsuuid' which is equivalent of the former version 2. Signed-off-by: Dmitry Kasatkin <d.kasatkin@samsung.com> Signed-off-by: Mimi Zohar <zohar@linux.vnet.ibm.com>

Pull device mapper updates from Mike Snitzer: "This pull request is later than I'd have liked because I was waiting for some performance data to help finally justify sending the long-standing dm-crypt cpu scalability improvements upstream. Unfortunately we came up short, so those dm-crypt changes will continue to wait, but it seems we're not far off. . Add dm_accept_partial_bio interface to DM core to allow DM targets to only process a portion of a bio, the remainder being sent in the next bio. This enables the old dm snapshot-origin target to only split write bios on chunk boundaries, read bios are now sent to the origin device unchanged. . Add DM core support for disabling WRITE SAME if the underlying SCSI layer disables it due to command failure. . Reduce lock contention in DM's bio-prison. . A few small cleanups and fixes to dm-thin and dm-era" * tag 'dm-3.16-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: dm thin: update discard_granularity to reflect the thin-pool blocksize dm bio prison: implement per bucket locking in the dm_bio_prison hash table dm: remove symbol export for dm_set_device_limits dm: disable WRITE SAME if it fails dm era: check for a non-NULL metadata object before closing it dm thin: return ENOSPC instead of EIO when error_if_no_space enabled dm thin: cleanup noflush_work to use a proper completion dm snapshot: do not split read bios sent to snapshot-origin target dm snapshot: allocate a per-target structure for snapshot-origin target dm: introduce dm_accept_partial_bio dm: change sector_count member in clone_info from sector_t to unsigned

Pull more ACPI and power management updates from Rafael Wysocki: "These are fixups on top of the previous PM+ACPI pull request, regression fixes (ACPI hotplug, cpufreq ppc-corenet), other bug fixes (ACPI reset, cpufreq), new PM trace points for system suspend profiling and a copyright notice update. Specifics: - I didn't remember correctly that the Hans de Goede's ACPI video patches actually didn't flip the video.use_native_backlight default, although we had discussed that and decided to do that. Since I said we would do that in the previous PM+ACPI pull request, make that change for real now. - ACPI bus check notifications for PCI host bridges don't cause the bus below the host bridge to be checked for changes as they should because of a mistake in the ACPI-based PCI hotplug (ACPIPHP) subsystem that forgets to add hotplug contexts to PCI host bridge ACPI device objects. Create hotplug contexts for PCI host bridges too as appropriate. - Revert recent cpufreq commit related to the big.LITTLE cpufreq driver that breaks arm64 builds. - Fix for a regression in the ppc-corenet cpufreq driver introduced during the 3.15 cycle and causing the driver to use the remainder from do_div instead of the quotient. From Ed Swarthout. - Resets triggered by panic activate a BUG_ON() in vmalloc.c on systems where the ACPI reset register is located in memory address space. Fix from Randy Wright. - Fix for a problem with cpufreq governors that decisions made by them may be suboptimal due to the fact that deferrable timers are used by them for CPU load sampling. From Srivatsa S Bhat. - Fix for a problem with the Tegra cpufreq driver where the CPU frequency is temporarily switched to a "stable" level that is different from both the initial and target frequencies during transitions which causes udelay() to expire earlier than it should sometimes. From Viresh Kumar. - New trace points and rework of some existing trace points for system suspend/resume profiling from Todd Brandt. - Assorted cpufreq fixes and cleanups from Stratos Karafotis and Viresh Kumar. - Copyright notice update for suspend-and-cpuhotplug.txt from Srivatsa S Bhat" * tag 'pm+acpi-3.16-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI / hotplug / PCI: Add hotplug contexts to PCI host bridges PM / sleep: trace events for device PM callbacks cpufreq: cpufreq-cpu0: remove dependency on THERMAL and REGULATOR cpufreq: tegra: update comment for clarity cpufreq: intel_pstate: Remove duplicate CPU ID check cpufreq: Mark CPU0 driver with CPUFREQ_NEED_INITIAL_FREQ_CHECK flag PM / Documentation: Update copyright in suspend-and-cpuhotplug.txt cpufreq: governor: remove copy_prev_load from 'struct cpu_dbs_common_info' cpufreq: governor: Be friendly towards latency-sensitive bursty workloads PM / sleep: trace events for suspend/resume cpufreq: ppc-corenet-cpu-freq: do_div use quotient Revert "cpufreq: Enable big.LITTLE cpufreq driver on arm64" cpufreq: Tegra: implement intermediate frequency callbacks cpufreq: add support for intermediate (stable) frequencies ACPI / video: Change the default for video.use_native_backlight to 1 ACPI: Fix bug when ACPI reset register is implemented in system memory

We have a number of front-end drivers for SDHCI_PLTFM, some of them use 'select MMC_SDHCI_PLTFM', others use 'depends on'. This is inconsistent and confusing, and in one case has also led to a build error because of incomplete dependencies: warning: (MMC_SDHCI_PXAV3 && MMC_SDHCI_PXAV2 && MMC_SDHCI_BCM_KONA) selects MMC_SDHCI_PLTFM which has unmet direct dependencies (MMC && MMC_SDHCI) drivers/built-in.o: In function `sdhci_sirf_resume': :(.text+0xaaacb4): undefined reference to `sdhci_resume_host' drivers/built-in.o: In function `sdhci_sirf_suspend': :(.text+0xaaacf8): undefined reference to `sdhci_suspend_host' drivers/built-in.o: In function `sdhci_sirf_probe': :(.text+0xaaaf44): undefined reference to `sdhci_add_host' :(.text+0xaaaf50): undefined reference to `sdhci_remove_host' This changes Kconfig to use 'depends on MMC_SDHCI_PLTFM' for all these cases, to fix the build error and make the logic more logical.

The MMC host driver should not select the pmic driver, since that may have other dependencies, notably i2c in this case. It's not clear what the exact requirement of the driver is, but to preserve the behavior, this patch changes the 'select' into 'depends on', meaning you now have to turn on TPS65010 explicitly and then MMC_OMAP.

The sdhci core was refactored recently and some of those refactorings required changes in every sdhci platform driver. Those updates happened around the same time as when the msm driver was merged so the refactorings missed the msm driver.

Dentry that had been through (or into) __dentry_kill() might be seen by shrink_dentry_list(); that's normal, it'll be taken off the shrink list and freed if __dentry_kill() has already finished. The problem is, its ->d_parent might be pointing to already freed dentry, so lock_parent() needs to be careful. We need to check that dentry hasn't already gone into __dentry_kill() *and* grab rcu_read_lock() before dropping ->d_lock - the latter makes sure that whatever we see in ->d_parent after dropping ->d_lock it won't be freed until we drop rcu_read_lock().

Merge tag 'pwm/for-3.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm Pull pwm changes from Thierry Reding: "The majority of these changes are cleanups and fixes across all drivers. Redundant error messages are removed and more PWM controllers set the .can_sleep flag to signal that they can't be used in atomic context. Support is added for the Broadcom Kona family of SoCs and the Intel LPSS driver can now probe PCI devices in addition to ACPI devices. Upon shutdown, the pwm-backlight driver will now power off the backlight. It also uses the new descriptor-based GPIO API for more concise GPIO handling. A large chunk of these changes also converts platforms to use the lookup mechanism rather than relying on the global number space to reference PWM devices. This is largely in preparation for more unification and cleanups in future patches.

DM thinp already checks whether the discard_granularity of the data device is a factor of the thin-pool block size. But when using the dm-thin-pool's discard passdown support, DM thinp was not selecting the max of the underlying data device's discard_granularity and the thin-pool's block size. Update set_discard_limits() to set discard_granularity to the max of these values. This enables blkdev_issue_discard() to properly align the discards that are sent to the DM thin device on a full block boundary. As such each discard will now cover an entire DM thin-pool block and the block will be reclaimed.

This device uses function 1 as the PCIe requester ID. This vendor has similar boards based on the same Marvell 88SE9235 chipset, but this patch was only tested with the 642L. Tested on ASUS Sabertooth 990FX (AMD).
