commit a614328ed1ce12a949f1c750666687346638170e
Author: Linus Walleij <linus.walleij@linaro.org>
Date:   Wed Apr 23 16:45:12 2014 +0200

    gpio: do not set up hardware for IRQ_TYPE_NONE
    
    Some GPIO irqchip drivers exploit the irqdomain mapping
    function to set up the IRQ default type in the hardware,
    make sure that if we pass IRQ_TYPE_NONE, no hardware setup
    whatsoever takes place (this should be the norm) until
    later when the IRQ gets utilized.

    pinctrl: rockchip: implement PIN_CONFIG_OUTPUT handling
    
    In some cases it is nice to be able to simply control a gpio output
    via the PIN_CONFIG_OUTPUT option without having a driver control it.
    Thus add support for it to the rockchip pinctrl driver.

    pinctrl: rockchip: return a complete config in pinconf_get
    
    Till now pinconf_get only set the argument value into the config parameter
    effectively removing the actual config param value. As other pinctrl drivers
    do, it might be nicer to keep the config param intact.
    Therefore construct a real pinconfig value from param and arg in pinconf_get

    We are currently embedding the same check from thread_info.h into
    syscall.h thanks to the way syscall_get_arch() was implemented in the
    audit tree.  Instead create a new function, is_32bit_task() which is
    similar to that found on the powerpc arch.  This simplifies the
    syscall.h code and makes the build/Kconfig requirements much easier

    The goal of this patch is to fix rtnelink notification. The main problem was
    about notification for fdb entry with more than one remote. Before the patch,
    when a remote was added to an existing fdb entry, the kernel advertised the
    first remote instead of the added one. Also when a remote was removed from a fdb
    entry with several remotes, the deleted remote was not advertised.

    * do not modify iovecs; use iov_iter_truncate()/iov_iter_advance() and

    * (racy) check for lustre VMAs intersecting with iovecs kept for now as

    Beginning to introduce those.  Just the callers for now, and it's
    clumsier than it'll eventually become; once we finish converting
    aio_read and aio_write instances, the things will get nicer.
    
    For now, these guys are in parallel to ->aio_read() and ->aio_write();
    they take iocb and iov_iter, with everything in iov_iter already
    validated.  File offset is passed in iocb->ki_pos, iov/nr_segs -
    in iov_iter.
    
    Main concerns in that series are stack footprint and ability to
    split the damn thing cleanly.

    cgroup: implement dynamic subtree controller enable/disable on the default hierarchy
    
    cgroup is switching away from multiple hierarchies and will use one
    unified default hierarchy where controllers can be dynamically enabled
    and disabled per subtree.  The default hierarchy will serve as the
    unified hierarchy to which all controllers are attached and a css on
    the default hierarchy would need to also serve the tasks of descendant
    cgroups which don't have the controller enabled - ie. the tree may be
    collapsed from leaf towards root when viewed from specific
    controllers.  This has been implemented through effective css in the
    previous patches.
    
    This patch finally implements dynamic subtree controller
    enable/disable on the default hierarchy via a new knob -
    "cgroup.subtree_control" which controls which controllers are enabled
    on the child cgroups.  Let's assume a hierarchy like the following.
    
      root - A - B - C
                   \ D
    
    root's "cgroup.subtree_control" determines which controllers are
    enabled on A.  A's on B.  B's on C and D.  This coincides with the
    fact that controllers on the immediate sub-level are used to
    distribute the resources of the parent.  In fact, it's natural to
    assume that resource control knobs of a child belong to its parent.
    Enabling a controller in "cgroup.subtree_control" declares that
    distribution of the respective resources of the cgroup will be
    controlled.  Note that this means that controller enable states are
    shared among siblings.
    
    The default hierarchy has an extra restriction - only cgroups which
    don't contain any task may have controllers enabled in
    "cgroup.subtree_control".  Combined with the other properties of the
    default hierarchy, this guarantees that, from the view point of
    controllers, tasks are only on the leaf cgroups.  In other words, only
    leaf csses may contain tasks.  This rules out situations where child
    cgroups compete against internal tasks of the parent, which is a
    competition between two different types of entities without any clear
    way to determine resource distribution between the two.  Different
    controllers handle it differently and all the implemented behaviors
    are ambiguous, ad-hoc, cumbersome and/or just wrong.  Having this
    structural constraints imposed from cgroup core removes the burden
    from controller implementations and enables showing one consistent
    behavior across all controllers.
    
    When a controller is enabled or disabled, css associations for the
    controller in the subtrees of each child should be updated.  After
    enabling, the whole subtree of a child should point to the new css of
    the child.  After disabling, the whole subtree of a child should point
    to the cgroup's css.  This is implemented by first updating cgroup
    states such that cgroup_e_css() result points to the appropriate css
    and then invoking cgroup_update_dfl_csses() which migrates all tasks
    in the affected subtrees to the self cgroup on the default hierarchy.
    
    * When read, "cgroup.subtree_control" lists all the currently enabled
      controllers on the children of the cgroup.
    
    * White-space separated list of controller names prefixed with either
      '+' or '-' can be written to "cgroup.subtree_control".  The ones
      prefixed with '+' are enabled on the controller and '-' disabled.
    
    * A controller can be enabled iff the parent's
      "cgroup.subtree_control" enables it and disabled iff no child's
      "cgroup.subtree_control" has it enabled.
    
    * If a cgroup has tasks, no controller can be enabled via
      "cgroup.subtree_control".  Likewise, if "cgroup.subtree_control" has
      some controllers enabled, tasks can't be migrated into the cgroup.
    
    * All controllers which aren't bound on other hierarchies are
      automatically associated with the root cgroup of the default
      hierarchy.  All the controllers which are bound to the default
      hierarchy are listed in the read-only file "cgroup.controllers" in
      the root directory.
    
    * "cgroup.controllers" in all non-root cgroups is read-only file whose
      content is equal to that of "cgroup.subtree_control" of the parent.
      This indicates which controllers can be used in the cgroup's
      "cgroup.subtree_control".
    
    This is still experimental and there are some holes, one of which is
    that ->can_attach() failure during cgroup_update_dfl_csses() may leave
    the cgroups in an undefined state.  The issues will be addressed by
    future patches.
    
    v2: Non-root cgroups now also have "cgroup.controllers".

    cgroup: prepare migration path for unified hierarchy
    
    Unified hierarchy implementation would require re-migrating tasks onto
    the same cgroup on the default hierarchy to reflect updated effective
    csses.  Update cgroup_migrate_prepare_dst() so that it accepts NULL as
    the destination cgrp.  When NULL is specified, the destination is
    considered to be the cgroup on the default hierarchy associated with
    each css_set.
    
    After this change, the identity check in cgroup_migrate_add_src()
    isn't sufficient for noop detection as the associated csses may change
    without any cgroup association changing.  The only way to tell whether
    a migration is noop or not is testing whether the source and
    destination csets are identical.  The noop check in
    cgroup_migrate_add_src() is removed and cset identity test is added to
    cgroup_migreate_prepare_dst().  If it's detected that source and
    destination csets are identical, the cset is removed removed from
    @preloaded_csets and all the migration nodes are cleared which makes
    cgroup_migrate() ignore the cset.
    
    Also, make the function append the destination css_sets to
    @preloaded_list so that destination css_sets always come after source
    css_sets.

    cgroup: update subsystem rebind restrictions
    
    Because the default root couldn't have any non-root csses attached to
    it, rebinding away from it was always allowed; however, the default
    hierarchy will soon host the unified hierarchy and have non-root csses
    so the rebind restrictions need to be updated accordingly.
    
    Instead of special casing rebinding from the default hierarchy and
    then checking whether the source hierarchy has children cgroups, which
    implies non-root csses for !dfl hierarchies, simply check whether the
    source hierarchy has non-root csses for the subsystem using
    css_next_child().

    Now that effective css handling has been added and iterators updated
    accordingly, it's safe to allow cgroup creation in the default
    hierarchy.  Unblock cgroup creation in the default hierarchy.
    
    As the default hierarchy will implement explicit enabling and

    cgroup: cgroup->subsys[] should be cleared after the css is offlined
    
    After a css finishes offlining, offline_css() mistakenly performs
    RCU_INIT_POINTER(css->cgroup->subsys[ss->id], css) which just sets the
    cgroup->subsys[] pointer to the current value.  The intention was to
    clear it after offline is complete, not reassign the same value.
    
    Update it to assign NULL instead of the current value.  This makes
    cgroup_css() to return NULL once offline is complete.  All the
    existing users of the function either can handle NULL return already
    or guarantee that the css doesn't get offlined.
    
    While this is a bugfix, as css lifetime is currently tied to the
    cgroup it belongs to, this bug doesn't cause any actual problems.

    cgroup: teach css_task_iter about effective csses
    
    Currently, css_task_iter iterates tasks associated with a css by
    visiting each css_set associated with the owning cgroup and walking
    tasks of each of them.  This works fine for !unified hierarchies as
    each cgroup has its own css for each associated subsystem on the
    hierarchy; however, on the planned unified hierarchy, a cgroup may not
    have csses associated and its tasks would be considered associated
    with the matching css of the nearest ancestor which has the subsystem
    enabled.
    
    This means that on the default unified hierarchy, just walking all
    tasks associated with a cgroup isn't enough to walk all tasks which
    are associated with the specified css.  If any of its children doesn't
    have the matching css enabled, task iteration should also include all
    tasks from the subtree.  We already added cgroup->e_csets[] to list
    all css_sets effectively associated with a given css and walk css_sets
    on that list instead to achieve such iteration.
    
    This patch updates css_task_iter iteration such that it walks css_sets
    on cgroup->e_csets[] instead of cgroup->cset_links if iteration is
    requested on an non-dummy css.  Thanks to the previous iteration
    update, this change can be achieved with the addition of
    css_task_iter->ss and minimal updates to css_advance_task_iter() and
    css_task_iter_start().

    cgroup: reorganize css_task_iter
    
    This patch reorganizes css_task_iter so that adding effective css
    support is easier.
    
    * s/->cset_link/->cset_pos/ and s/->task/->task_pos/ for consistency
    
    * ->origin_css is used to determine whether the iteration reached the
      last css_set.  Replace it with explicit ->cset_head so that
      css_advance_task_iter() doesn't have to know the termination
      condition directly.
    
    * css_task_iter_next() currently assumes that it's walking list of
      cgrp_cset_link and reaches into the current cset through the current
      link to determine the termination conditions for task walking.  As
      this won't always be true for effective css walking, add
      ->tasks_head and ->mg_tasks_head and use them to control task
      walking so that css_task_iter_next() doesn't have to know how
      css_sets are being walked.
    
    This patch doesn't make any behavior changes.  The iteration logic
    stays unchanged after the patch.

    cgroup: implement cgroup->e_csets[]
    
    On the default unified hierarchy, a cgroup may be associated with
    csses of its ancestors, which means that a css of a given cgroup may
    be associated with css_sets of descendant cgroups.  This means that we
    can't walk all tasks associated with a css by iterating the css_sets
    associated with the cgroup as there are css_sets which are pointing to
    the css but linked on the descendants.
    
    This patch adds per-subsystem list heads cgroup->e_csets[].  Any
    css_set which is pointing to a css is linked to
    css->cgroup->e_csets[$SUBSYS_ID] through
    css_set->e_cset_node[$SUBSYS_ID].  The lists are protected by
    css_set_rwsem and will allow us to walk all css_sets associated with a
    given css so that we can find out all associated tasks.

    cgroup: introduce effective cgroup_subsys_state
    
    In the planned default unified hierarchy, controllers may get
    dynamically attached to and detached from a cgroup and a cgroup may
    not have csses for all the controllers associated with the hierarchy.
    
    When a cgroup doesn't have its own css for a given controller, the css
    of the nearest ancestor with the controller enabled will be used,
    which is called the effective css.  This patch introduces
    cgroup_e_css() and for_each_e_css() to access the effective csses and
    convert compare_css_sets(), find_existing_css_set() and
    cgroup_migrate() to use the effective csses so that they can handle
    cgroups with partial csses correctly.
    
    This means that for two css_sets to be considered identical, they
    should have both matching csses and cgroups.  compare_css_sets()
    already compares both, not for correctness but for optimization.  As
    this now becomes a matter of correctness, update the comments
    accordingly.
    
    For all !default hierarchies, cgroup_e_css() always equals
    cgroup_css(), so this patch doesn't change behavior.
    
    While at it, fix incorrect locking comment for for_each_css().

    pinctrl: single: Clear pin interrupts enabled by bootloader
    
    Since we set up device wake-up interrupts as pinctrl-single
    interrupts, we now must use the standard request_irq and
    related functions to manage them.
    
    If the pin interrupts are enabled for some pins at boot,
    the wake-up events can show up as constantly pending
    at least on omaps and will hang the system unless the related
    device driver clears the event at the device.
    
    To fix this, let's clear the interrupt flags during init,
    and print out a warning so the board maintainers can update
    their drivers to do proper request_irq for the driver specific
    wake-up events.

    ASoC: core: Don't break component searching if both id and num_dai are 0
    
    The commit e41975ed (ASoC: core: Fix the DAI name getting) added a break
    within the "if (id < 0 || id >= pos->num_dai)" while the original design
    of the search didn't break the loop if that condition contented but only
    mark the ret error and let it go on to search the next component.
    
    In a case like dmaengine which's not a dai but as a component sharing an
    identical name with a dai, both the id and pos->num_dai here could be 0.
    If we break the search, we may never find the dai we want as it might be
    placed behind its dmaengine in the component list.
    
    So this patch fixes the issue above by following the original design to
    let the search carry on.

@wildea01 wildea01 word-at-a-time: avoid undefined behaviour in zero_bytemask macro
The asm-generic, big-endian version of zero_bytemask creates a mask of
bytes preceding the first zero-byte by left shifting ~0ul based on the
position of the first zero byte.

Unfortunately, if the first (top) byte is zero, the output of
prep_zero_mask has only the top bit set, resulting in undefined C
behaviour as we shift left by an amount equal to the width of the type.
As it happens, GCC doesn't manage to spot this through the call to fls(),
but the issue remains if architectures choose to implement their shift
instructions differently.

An example would be arch/arm/ (AArch32), where LSL Rd, Rn, #32 results
in Rd == 0x0, whilst on arch/arm64 (AArch64) LSL Xd, Xn, #64 results in
Xd == Xn.

Rather than check explicitly for the problematic shift, this patch adds
an extra shift by 1, replacing fls with __fls. Since zero_bytemask is
never called with a zero argument (has_zero() is used to check the data
first), we don't need to worry about calling __fls(0), which is
undefined.
