Pull scheduler updates from Thomas Gleixner:

- Revert the printk format based wchan() symbol resolution as it can
leak the raw value in case that the symbol is not resolvable.

- Make wchan() more robust and work with all kind of unwinders by
enforcing that the task stays blocked while unwinding is in progress.

- Prevent sched_fork() from accessing an invalid sched_task_group

- Improve asymmetric packing logic

- Extend scheduler statistics to RT and DL scheduling classes and add
statistics for bandwith burst to the SCHED_FAIR class.

- Properly account SCHED_IDLE entities

- Prevent a potential deadlock when initial priority is assigned to a
newly created kthread. A recent change to plug a race between cpuset
and __sched_setscheduler() introduced a new lock dependency which is
now triggered. Break the lock dependency chain by moving the priority
assignment to the thread function.

- Fix the idle time reporting in /proc/uptime for NOHZ enabled systems.

- Improve idle balancing in general and especially for NOHZ enabled
systems.

- Provide proper interfaces for live patching so it does not have to
fiddle with scheduler internals.

- Add cluster aware scheduling support.

- A small set of tweaks for RT (irqwork, wait_task_inactive(), various
scheduler options and delaying mmdrop)

- The usual small tweaks and improvements all over the place

irq_work: Handle some irq_work in a per-CPU thread on PREEMPT_RT

The irq_work callback is invoked in hard IRQ context. By default all
callbacks are scheduled for invocation right away (given supported by
the architecture) except for the ones marked IRQ_WORK_LAZY which are
delayed until the next timer-tick.

While looking over the callbacks, some of them may acquire locks
(spinlock_t, rwlock_t) which are transformed into sleeping locks on
PREEMPT_RT and must not be acquired in hard IRQ context.
Changing the locks into locks which could be acquired in this context
will lead to other problems such as increased latencies if everything
in the chain has IRQ-off locks. This will not solve all the issues as
one callback has been noticed which invoked kref_put() and its callback
invokes kfree() and this can not be invoked in hardirq context.

Some callbacks are required to be invoked in hardirq context even on
PREEMPT_RT to work properly. This includes for instance the NO_HZ
callback which needs to be able to observe the idle context.

The callbacks which require to be run in hardirq have already been
marked. Use this information to split the callbacks onto the two lists
on PREEMPT_RT:
- lazy_list
Work items which are not marked with IRQ_WORK_HARD_IRQ will be added
to this list. Callbacks on this list will be invoked from a per-CPU
thread.
The handler here may acquire sleeping locks such as spinlock_t and
invoke kfree().

- raised_list
Work items which are marked with IRQ_WORK_HARD_IRQ will be added to
this list. They will be invoked in hardirq context and must not
acquire any sleeping locks.

The wake up of the per-CPU thread occurs from irq_work handler/
hardirq context. The thread runs with lowest RT priority to ensure it
runs before any SCHED_OTHER tasks do.

[bigeasy: melt tglx's irq_work_tick_soft() which splits irq_work_tick() into a
hard and soft variant. Collected fixes over time from Steven
Rostedt and Mike Galbraith. Move to per-CPU threads instead of
softirq as suggested by PeterZ.]

irq_work: Allow irq_work_sync() to sleep if irq_work() no IRQ support.

irq_work() triggers instantly an interrupt if supported by the
architecture. Otherwise the work will be processed on the next timer
tick. In worst case irq_work_sync() could spin up to a jiffy.

irq_work_sync() is usually used in tear down context which is fully
preemptible. Based on review irq_work_sync() is invoked from preemptible
context and there is one waiter at a time. This qualifies it to use
rcuwait for synchronisation.

Let irq_work_sync() synchronize with rcuwait if the architecture
processes irqwork via the timer tick.
