Unlike running, the runnable part can't be directly propagated through
the hierarchy when we migrate a task. The main reason is that runnable
time can be shared with other sched_entities that stay on the rq and
this runnable time will also remain on prev cfs_rq and must not be
removed.

Instead, we can estimate what should be the new runnable of the prev
cfs_rq and check that this estimation stay in a possible range. The
prop_runnable_sum is a good estimation when adding runnable_sum but
fails most often when we remove it. Instead, we could use the formula
below instead:

  gcfs_rq's runnable_sum = gcfs_rq->avg.load_sum / gcfs_rq->load.weight

which assumes that tasks are equally runnable which is not true but
easy to compute.

Beside these estimates, we have several simple rules that help us to filter
out wrong ones:

 - ge->avg.runnable_sum <= than LOAD_AVG_MAX
 - ge->avg.runnable_sum >= ge->avg.running_sum (ge->avg.util_sum << LOAD_AVG_MAX)
 - ge->avg.runnable_sum can't increase when we detach a task

The effect of these fixes is better cgroups balancing.

The following cleanup commit:

  50816c48 ("sched/wait: Standardize internal naming of wait-queue entries")

... unintentionally changed the behavior of add_wait_queue() from
inserting the wait entry at the head of the wait queue to the tail
of the wait queue.

Beyond a negative performance impact this change in behavior
theoretically also breaks wait queues which mix exclusive and
non-exclusive waiters, as non-exclusive waiters will not be
woken up if they are queued behind enough exclusive waiters.

Things like this will probably keep showing up for other architectures
and other special cases.

I actually thought we already used %lx for this, and that is indeed
_historically_ the case, but we moved to %p when merging the 32-bit and
64-bit cases as a convenient way to get the formatting right (ie
automatically picking "%08lx" vs "%016lx" based on register size).

So just turn this %p into %px.

SNDRV_CTL_IOCTL_PCM_INFO. This case calls snd_pcm_info_user() which

  just adding another type and id -- tiwai ]

Pull documentation fixes from Jonathan Corbet:
 "A handful of documentation fixes.

  The most significant of these addresses a problem with the new warning
  mode: it can break the build when confronted with a source file
  containing malformed kerneldoc comments"

* tag 'docs-4.15-fixes' of git://git.lwn.net/linux:
  Documentation: fix docs build error after source file removed
  scsi: documentation: Fix case of 'scsi_device' struct mention(s)
  genericirq.rst: Remove :c:func:`...` in code blocks
  dmaengine: doc : Fix warning "Title underline too short" while make xmldocs
  scripts/kernel-doc: Don't fail with status != 0 if error encountered with -none

The irq_balancing_disabled and irq_is_percpu{,_devid} functions are
clearly intended to return bool like the functions in
kernel/irq/settings.h, but actually return an int containing a masked
value of desc->status_use_accessors. This can lead to subtle breakage
if, for example, the return value is subsequently truncated when
assigned to a narrower type.

As Linus points out:

| In particular, what can (and _has_ happened) is that people end up
| using these functions that return true or false, and they assign the
| result to something like a bitfield (or a char) or whatever.
|
| And the code looks *obviously* correct, when you have things like
|
|      dev->percpu = irq_is_percpu_devid(dev->irq);
|
| and that "percpu" thing is just one status bit among many. It may even
| *work*, because maybe that "percpu" flag ends up not being all that
| important, or it just happens to never be set on the particular
| hardware that people end up testing.
|
| But while it looks obviously correct, and might even work, it's really
| fundamentally broken. Because that "true or false" function didn't
| actually return 0/1, it returned 0 or 0x20000.
|
| And 0x20000 may not fit in a bitmask or a "char" or whatever.

Fix the problem by consistently using bool as the return type for these
functions.

The previous commit which made the operator precedence in
irq_matrix_available() explicit made the implicit brokenness explicitely
wrong. It was wrong in the original commit already. The overworked
maintainer did not notice it either when merging the patch.

Replace the confusing '?' construct by a simple and obvious if ().

The chip family of TILEPro and TILE-Gx was developed by Tilera, which
was eventually acquired by Mellanox.  The tile architecture was added to
the kernel in 2010 and first appeared in 2.6.36.

Now at Mellanox we are developing new chips based on the ARM64
architecture; our last TILE-Gx chip (the Gx72) was released in 2013, and
our customers using tile architecture products are not, as far as we
know, looking to upgrade to newer kernel releases.  In the absence of
someone in the community stepping up to take over maintainership, this
commit marks the architecture as orphaned.
