Even though best_energy_cpu is idle and which would consume
same amount of energy as prev cpu, due to 6% check with prev cpu,
we end up choosing prev cpu over best_energy_cpu for the tasks.
This leads to increase in runnables. Choose best_energy_cpu when
it is idle and shallowest c-state over prev cpu in such scenarios
to avoid runnables.

Because pids->limit can be changed concurrently (but we don't want to
take a lock because it would be needlessly expensive), use atomic64_ts
instead.

commit e66b39af00 upstream.
008847f66c ("workqueue: allow rescuer thread to do more work.") made
the rescuer worker requeue the pwq immediately if there may be more
work items which need rescuing instead of waiting for the next mayday
timer expiration. Unfortunately, it doesn't check whether the pwq is
already on the mayday list and unconditionally gets the ref and moves
it onto the list. This doesn't corrupt the list but creates an
additional reference to the pwq. It got queued twice but will only be
removed once.
This leak later can trigger pwq refcnt warning on workqueue
destruction and prevent freeing of the workqueue.

commit def98c84b6 upstream.
Before actually destrying a workqueue, destroy_workqueue() checks
whether it's actually idle. If it isn't, it prints out a bunch of
warning messages and leaves the workqueue dangling. It unfortunately
has a couple issues.
* Mayday list queueing increments pwq's refcnts which gets detected as
busy and fails the sanity checks. However, because mayday list
queueing is asynchronous, this condition can happen without any
actual work items left in the workqueue.
* Sanity check failure leaves the sysfs interface behind too which can
lead to init failure of newer instances of the workqueue.
This patch fixes the above two by
* If a workqueue has a rescuer, disable and kill the rescuer before
sanity checks. Disabling and killing is guaranteed to flush the
existing mayday list.
* Remove sysfs interface before sanity checks.

commit 7b8474466e upstream.
On compat interfaces, the high order bits of nanoseconds should be zeroed
out. This is because the application code or the libc do not guarantee
zeroing of these. If used without zeroing, kernel might be at risk of using
timespec values incorrectly.
Originally it was handled correctly, but lost during is_compat_syscall()
cleanup. Revert the condition back to check CONFIG_64BIT.

The current derivation of pfns/page structures has a fair
amount of complexity in it, and can be simplified. For example,
there need not be completely separate cases for pages that are
all remapped into the vmalloc space, but were allocated
differently (i.e. atomic allocations vs contiguous allocations).
So, simplify the handling for those, and leverage iommu_dma_mmap()
and iommu_dma_get_sgtable(), as there is nothing fastmap-specific
with the way pages are mapped into userspace and how we construct
an sg-table respectively.

The generic atomic pool is initialized at the postcore
initcall level. However, the same function is called to
initialize the atomic pool for fastmap at a later level,
and that function makes it so that the generic pool is
clobbered, and we start using the same atomic pool for
both fastmap and allocations outside of fastmap.
Fix this by adding support in the atomic pool framework
to create and utilize different atomic pools, and creating
a private atomic pool for fastmap.

This patch adds a parameter to select_task_rq, sibling_count_hint
allowing the caller, where it has this information, to inform the
sched_class the number of tasks that are being woken up as part of
the same event.
The wake_q mechanism is one case where this information is available.
select_task_rq_fair can then use the information to detect that it
needs to widen the search space for task placement in order to avoid
overloading the last-level cache domain's CPUs.
* * *
The reason I am investigating this change is the following use case
on ARM big.LITTLE (asymmetrical CPU capacity): 1 task per CPU, which
all repeatedly do X amount of work then
pthread_barrier_wait (i.e. sleep until the last task finishes its X
and hits the barrier). On big.LITTLE, the tasks which get a "big" CPU
finish faster, and then those CPUs pull over the tasks that are still
running:
v CPU v ->time->
-------------
0 (big) 11111 /333
-------------
1 (big) 22222 /444|
-------------
2 (LITTLE) 333333/
-------------
3 (LITTLE) 444444/
-------------
Now when task 4 hits the barrier (at |) and wakes the others up,
there are 4 tasks with prev_cpu=<big> and 0 tasks with
prev_cpu=<little>. want_affine therefore means that we'll only look
in CPUs 0 and 1 (sd_llc), so tasks will be unnecessarily coscheduled
on the bigs until the next load balance, something like this:
v CPU v ->time->
------------------------
0 (big) 11111 /333 31313\33333
------------------------
1 (big) 22222 /444|424\4444444
------------------------
2 (LITTLE) 333333/ \222222
------------------------
3 (LITTLE) 444444/ \1111
------------------------
^^^
underutilization
So, I'm trying to get want_affine = 0 for these tasks.
I don't _think_ any incarnation of the wakee_flips mechanism can help
us here because which task is waker and which tasks are wakees
generally changes with each iteration.
However pthread_barrier_wait (or more accurately FUTEX_WAKE) has the
nice property that we know exactly how many tasks are being woken, so
we can cheat.
It might be a disadvantage that we "widen" _every_ task that's woken in
an event, while select_idle_sibling would work fine for the first
sd_llc_size - 1 tasks.
IIUC, if wake_affine() behaves correctly this trick wouldn't be
necessary on SMP systems, so it might be best guarded by the presence
of SD_ASYM_CPUCAPACITY?
* * *
Final note..
In order to observe "perfect" behaviour for this use case, I also had
to disable the TTWU_QUEUE sched feature. Suppose during the wakeup
above we are working through the work queue and have placed tasks 3
and 2, and are about to place task 1:
v CPU v ->time->
--------------
0 (big) 11111 /333 3
--------------
1 (big) 22222 /444|4
--------------
2 (LITTLE) 333333/ 2
--------------
3 (LITTLE) 444444/ <- Task 1 should go here
--------------
If TTWU_QUEUE is enabled, we will not yet have enqueued task
2 (having instead sent a reschedule IPI) or attached its load to CPU
2. So we are likely to also place task 1 on cpu 2. Disabling
TTWU_QUEUE means that we enqueue task 2 before placing task 1,
solving this issue. TTWU_QUEUE is there to minimise rq lock
contention, and I guess that this contention is less of an issue on
big.LITTLE systems since they have relatively few CPUs, which
suggests the trade-off makes sense here.

The current code uses the rq->cpu_capacity_orig while sorting
the min/mid/max CPUs while rebuilding the scheduler domains. This
rq->cpu_capacity_orig is subjected to changed when the scaling max
frequency is clipped for that CPU's frequency domain. Since we don't
recompute the min/mid/max CPUs when the capacity is changed, the
sorting becomes incorrect later when the frequency limits are lifted.
The task CPU selection algorithm depends heavily on min/mid/max CPUs
and changing them on the fly results in incorrect task placement.
Hence use the true capacity of CPUs while sorting the min/mid/max
CPUs. This means that the sorting gets changed only when CPUs are
hotplugged out, otherwise these reflect the correct topology
all the time.
The max_cpu_capacity struct in root domain also maintains the
max CPU and its capacity. Since we now use true capacity, there
is no need to compute this on the fly. So move this evaluation from
the periodic load balancer to the scheduler domain rebuilding.
The rq->cpu_capacity_orig is still subjected to change upon frequency
or thermal limits. So we still identify the cases where tasks not
fitting on the max/mid CPUs when the capacity is reduced.

It is quite a common occurrence that we have a misfit task (a task
running on a CPU which is close to the capacity limit of that CPU)
in the system AND we have recently done a load balance operation.
Normal load-balance rate limiting means we can leave those tasks on
the restrictive CPU for a few hundred ms before we move them.
Inspired by the work Leo Yan did on balancing misfits.
This patch reduces the balance interval to one jiffy when there are such
tasks running.
There appears to be no impact on interactive performance from this
patch.
