      ASoC: wcd9xxx: Avoid micbias glitches during audio playback · 8babaa62
      Phani Kumar Uppalapati authored
      During audio playback over headset, micbias output is switched
      to vddio and it's parameters are programmed so that it will do
      button polling with a voltage equal to vddio (1.8v). It is observed
      that during this polling interval there is a drop in micbias
      voltage which would cause issues with button press. Avoid this
      voltage drop by disabling mbhc micbias when vddio switch is enabled.

      ASoC: wcd9xxx: Change PA on and VDDIO switch sequence · 1279e9b6
      Phani Kumar Uppalapati authored
      During removing and re-inserting of headset while music
      playback is ON, mbhc driver disables HPH PA and re-enables
      it once the detection is completed. After enabling PA, it
      switches micbias output to VDDIO to avoid polling noise on
      the headset. This sequence would cause a glitch because PA
      is already enabled while switching to VDDIO is taking place.
      Avoid this glitch by changing the sequence - switch to vddio
      and then enable HPH PA.

      ARM: 7449/1: use generic strnlen_user and strncpy_from_user functions · 69d7e62f
      Will Deacon authored
      This patch implements the word-at-a-time interface for ARM using the
      same algorithm as x86. We use the fls macro from ARMv5 onwards, where
      we have a clz instruction available which saves us a mov instruction
      when targetting Thumb-2. For older CPUs, we use the magic 0x0ff0001
      constant. Big-endian configurations make use of the implementation from
      asm-generic.
      
      With this implemented, we can replace our byte-at-a-time strnlen_user
      and strncpy_from_user functions with the optimised generic versions.

      lib: add generic strnlen_user() function
      
      This adds a new generic optimized strnlen_user() function that uses the
      <asm/word-at-a-time.h> infrastructure to portably do efficient string
      handling.
      
      In many ways, strnlen is much simpler than strncpy, and in particular we
      can always pre-align the words we load from memory.  That means that all
      the worries about alignment etc are a non-issue, so this one can easily
      be used on any architecture.  You obviously do have to do the
      appropriate word-at-a-time.h macros.

      word-at-a-time: make the interfaces truly generic
      
      This changes the interfaces in <asm/word-at-a-time.h> to be a bit more
      complicated, but a lot more generic.
      
      In particular, it allows us to really do the operations efficiently on
      both little-endian and big-endian machines, pretty much regardless of
      machine details.  For example, if you can rely on a fast population
      count instruction on your architecture, this will allow you to make your
      optimized <asm/word-at-a-time.h> file with that.
      
      NOTE! The "generic" version in include/asm-generic/word-at-a-time.h is
      not truly generic, it actually only works on big-endian.  Why? Because
      on little-endian the generic algorithms are wasteful, since you can
      inevitably do better. The x86 implementation is an example of that.
      
      (The only truly non-generic part of the asm-generic implementation is
      the "find_zero()" function, and you could make a little-endian version
      of it.  And if the Kbuild infrastructure allowed us to pick a particular
      header file, that would be lovely)
      
      The <asm/word-at-a-time.h> functions are as follows:
      
       - WORD_AT_A_TIME_CONSTANTS: specific constants that the algorithm
         uses.
      
       - has_zero(): take a word, and determine if it has a zero byte in it.
         It gets the word, the pointer to the constant pool, and a pointer to
         an intermediate "data" field it can set.
      
         This is the "quick-and-dirty" zero tester: it's what is run inside
         the hot loops.
      
       - "prep_zero_mask()": take the word, the data that has_zero() produced,
         and the constant pool, and generate an *exact* mask of which byte had
         the first zero.  This is run directly *outside* the loop, and allows
         the "has_zero()" function to answer the "is there a zero byte"
         question without necessarily getting exactly *which* byte is the
         first one to contain a zero.
      
         If you do multiple byte lookups concurrently (eg "hash_name()", which
         looks for both NUL and '/' bytes), after you've done the prep_zero_mask()
         phase, the result of those can be or'ed together to get the "either
         or" case.
      
       - The result from "prep_zero_mask()" can then be fed into "find_zero()"
         (to find the byte offset of the first byte that was zero) or into
         "zero_bytemask()" (to find the bytemask of the bytes preceding the
         zero byte).
      
         The existence of zero_bytemask() is optional, and is not necessary
         for the normal string routines.  But dentry name hashing needs it, so
         if you enable DENTRY_WORD_AT_A_TIME you need to expose it.
      
      This changes the generic strncpy_from_user() function and the dentry
      hashing functions to use these modified word-at-a-time interfaces.  This
      gets us back to the optimized state of the x86 strncpy that we lost in
      the previous commit when moving over to the generic version.

      cgroup: Fix use after free of cgrp (cgrp->css_sets) · e72e9a22
      Hans de Goede authored
      Running a 3.4 kernel + Fedora-18 (systemd) userland on my Allwinner A10
      (arm cortex a8), I'm seeing repeated, reproducable list_del list corruption
      errors when build with CONFIG_DEBUG_LIST, and the backtrace always shows
      free_css_set_work as the function making the problematic list_del call.
      
      I've tracked this doen to a use after free of the cgrp struct, specifically
      of the cgrp->css_sets list_head, which gets cleared by free_css_set_work.
      
      Since free_css_set_work runs form a workqueue, it is possible for it to not be
      done with clearing the list when the cgrp gets free-ed. To avoid this the code
      adding the links increases cgrp->count, and the freeing code running from the
      workqueue decreases cgrp->count *after* doing list_del, and then if the count
      goes to 0 calls cgroup_wakeup_rmdir_waiter().
      
      However cgroup_rmdir() is missing a check for cgrp->count != 0, causing it
      to still continue with the rmdir (which leads to the free-ing of the cgrp),
      before free_css_set_work is done. Sometimes the free-ed memory is re-used
      before free_css_set_work gets around to unlinking link->cgrp_link_list,
      triggering the list_del list corruption messages.
      
      This patch fixes this by properly checking for cgrp->count != 0 and waiting
      for the cgroup_rmdir_waitq in that case.

      Replacing mod_timer_pinned() with del_timer() and add_timer_on()

      cpufreq: interactive: Reset last evaluated jiffy in idle callback · 3510a80c
      Junjie Wu authored
      When CPU has been busy for a long time, last evaluated jiffy will be
      quite behind because the timer would have been canceled. We don't want
      to schedule a timer to fire in the past as load will always be 100%.
      
      Reset last evaluated jiffy so that timer will be scheduled for the
      next window.

      cpufreq: interactive: Align timer windows for all CPUs · ba061435
      Junjie Wu authored
      It's more advantageous to evaluate all CPUs at same time so that
      interactive governor gets a complete picture of the load on
      each CPU at a specific time. It could also reduce number of speed
      changes made if there are many CPUs controlled by same policy. In
      addition, waking up all CPUs at same time would allow the cluster
      to go into a deeper sleep state when it's idle.

      This reverts commit 7b46e2e6.
      
      Revert "cpufreq: interactive: Allow 1 ms error in above_hispeed_delay comparisons"
      
      This reverts commit ff6af80775231f1dfab8353d0b665718222218bf.
      
      Commit ff6af807 tries to avoid a corner case where frequency is stuck in
      hispeed_freq for one additional window. For example, if timer_rate is
      20ms, and go_hispeed_delay is 40ms, frequency might be stuck at
      hispeed_freq for 60ms due to imprecision in jiffies. Same problem can be
      easily solved by making go_hispeed_delay 1ms smaller instead of changing
      the code.

      introduced a change to cpufreq_interactive_timer_start() in order

      necessary.

      Governors other than ondemand and conservative can also use
      get_cpu_idle_time() and they aren't required to compile
      cpufreq_governor.c. So, move these independent routines to
      cpufreq.c instead.

      msm: mdss: delay iommu mapping of buffers until commit · b02091fe
      Adrian Salido-Moreno authored
      Currently iommu map call is done in client's context during overlay
      play, this requires iommu attachment to correctly map buffers.
      This mapping can be delayed until the actual commit and avoid
      unnecessary delays in client's context. Also, only unmap buffers if they
      have been mapped, instead of checking if iommu is attached.

      Kalyan Thota authored
      In secure case, when same buffer is queued in multiple
      composition cycles we should map it before unmapping it
      so that TZ will not clear the buffer content.
      
      In the former case ref count can be zero which can lead to TZ
      clearing the buffer
