Some drivers dealing with a gpio_chip might need to act on its
descriptors directly; one example is pinctrl drivers that need to lock a
GPIO for being used as IRQ using gpiod_lock_as_irq().
This patch exports a gpiochip_get_desc() function that returns the
GPIO descriptor at the requested index. I

Greg already queued my trivial patch to fix this for the v3.13.y branc
Currently kobject_uevent has somewhat unpredictable semantics. The point
is, since it may call a usermode helper and wait for it to execute
(UMH_WAIT_EXEC), it is impossible to say for sure what lock dependencies
it will introduce for the caller - strictly speaking it depends on what
fs the binary
We release the slab_mutex while calling sysfs_slab_add from
__kmem_cache_create since commit 66c4c35c6bc5, because kobject_uevent
called by sysfs_slab_add might block waiting for the usermode helper to
exec, which would result in a deadlock if we took the slab_mutex while
executing it.

cgroup_taskset_cur_css() will be removed during the planned
resturcturing of migration path. The only use of
cgroup_taskset_cur_css() is finding out the old cgroup_subsys_state of
the leader in cpuset_attach(). This usage can easily be removed by
remembering the old value from cpuset_can_attach()
Instead of repeatedly locking and unlocking css_set_rwsem inside
cgroup_task_migrate(), update cgroup_attach_task() to grab it outside
of the loop and update cgroup_task_migrate() to use
put_css_set_locked().

Now that css_task_iter_start/next_end() supports blocking while
iterating, there's no reason to use css_scan_tasks() which is more
cumbersome to use and scheduled to be removed.
Convert all css_scan_tasks() usages in cpuset to
css_task_iter_start/next/end(). This simplifies the code by removing
h
cgroup_task_count() read-locks css_set_lock and walks all tasks to
count them and then returns the result. The only thing all the users
want is determining whether the cgroup is empty or not. This patch
implements cgroup_has_tasks() which tests whether cgroup->cset_links
is empty, replaces all cg
Reimplement cgroup_transfer_tasks() so that it repeatedly fetches the
first task in the cgroup and then tranfers it. This achieves the same
result without using css_scan_tasks() which is scheduled to be
removed.

Currently there are two ways to walk tasks of a cgroup -
css_task_iter_start/next/end() and css_scan_tasks(). The latter
builds on the former but allows blocking while iterating.
Unfortunately, the way css_scan_tasks() is implemented is rather
nasty, it uses a priority heap of pointers to extract
Tasks are not linked on their css_sets until cgroup task iteration is
actually used. This is to avoid incurring overhead on the fork and
exit paths for systems which have cgroup compiled in but don't use it.
This lazy binding also affects the task migration path. It has to be
careful so that it
Before kernfs conversion, due to the way super_block lookup works,
cgroup roots were created and made visible before being fully
initialized. This in turn required a special flag to mark that the
root hasn't been fully initialized so that the destruction path can
tell fully bound ones from half in
Move it above so that prototype isn't necessary. Let's also move the
definition of use_task_css_set_links next to it.
This is purely cosmetic.

Commit 96286b576690 ("dmaengine: Add support for BCM2835") added an
optional dependency on MACH_BCM2708. But there's no Kconfig symbol
MACH_BCM2708.
(There was an entry for MACH_BCM2708 in arch/arm/tools/mach-types from
v2.6.37 until v3.2. But it seems that entry was never used in the tree.)

Commit f615136c06a7 ("xtensa: add SMP support") added "select
