      evm: provide option to protect additional SMACK xattrs · 3e38df56
      Dmitry Kasatkin authored
      Newer versions of SMACK introduced following security xattrs:
      SMACK64EXEC, SMACK64TRANSMUTE and SMACK64MMAP.
      
      To protect these xattrs, this patch includes them in the HMAC
      calculation.  However, for backwards compatibility with existing
      labeled filesystems, including these xattrs needs to be
      configurable.
      
      Changelog:
      - Add SMACK dependency on new option (Mimi)

      evm: replace HMAC version with attribute mask · d3b33679
      Dmitry Kasatkin authored
      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.

      ima: prevent new digsig xattr from being replaced · 060bdebf
      Mimi Zohar authored
      Even though a new xattr will only be appraised on the next access,
      set the DIGSIG flag to prevent a signature from being replaced with
      a hash on file close.

       "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.

      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"

      mmc: simplify SDHCI Kconfig dependencies · 5d01b768
      Arnd Bergmann authored
      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.

      mmc: omap: don't select TPS65010 · 60a549fc
      Arnd Bergmann authored
      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.

      Stephen Boyd authored
      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.
      Hook in the basic library functions so that we can boot apq8074
      dragonboards again instead of crashing when we try to jump to
      NULL function pointers.

      lock_parent: don't step on stale ->d_parent of all-but-freed one · c2338f2d
      Al Viro authored
      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().

       "The majority of these changes are cleanups and fixes across all

        controllers set the .can_sleep flag to signal that they can't be used

        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.  Eventually it will allow

      dm thin: update discard_granularity to reflect the thin-pool blocksize · 09869de5
      Lukas Czerner authored
      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.
