Excessive logging due to several successive memory allocation failure
may cause a watchdog bite. Hence, this change adds ratelimit to logging
on memory allocation failure.

The debug option to always ON the GPU clocks does not check the regulator
state. If the user tries to set this option while GPU is in Slumber state
then enabling clocks will fail.
Make sure we enable the GPU regulators before enabling its clocks.

prepare_to_wait() will enqueue the thread on the given queue
and put it into the given execution state,
which is TASK_INTERRUPTIBLE.
Further processing in function, calls mutex_lock(),
will go into a new version of the going-to-sleep code,
changing the task state.
That, of course, may well interfere with the outer
sleeping code.
So, nesting of sleeping primitives in this way is discouraged.
And new warning was added to point out this kind of nesting.
Fix the nesting of sleeping primitives with the new solution
provide in linux kernel.

Live Lock due to task spinning while unqueue of CPU osq_node
from optimistic_spin_queue. Task T1 had decremented mutex count to
acquire the lock on CPU0. Before setting owner it got preempted. On
CPU1 task T2 acquired osq_lock and started spinning on owner of mutex
with preemption disabled. CPU1 runq has one task, so need_resched will
not be set. On CPU0 task T3 tried to acquire osq_lock to spin on the
same mutex. At this time following scenario causes soft lockup:
After preemption of task T1, RT task T3 tried to acquire the same
mutex. It will start spinning on the osq_lock until the lock is available
or need_resched is set. For RT task, need_resched will not be set. Task T3
will not be able to bail out of the infinite loop.

Conntrack, if enabled, verifies complete checksum on all tcp
packets. If a packet is corrupted, it sets ip_summed field
to CHECKSUM_COMPLETE and checksum valid field to false.
With these changes such packet will be dropped.
Packets that are corrupted can go into userspace even when
the checksum is wrong. The io_vec library pushes the data into
pipe before checking the checksum. If the checksum is wrong,
the copied data is not reverted. Users observe corrupted data
in the application memory due to such corrupted packets.
This fix is to plug one such hole.
This change might be redundant on kernels after v4.9.

Userspace can set the default IRQ affinity setting by writing into
/proc/irq/default_smp_affinity file. When an IRQ affinity is
broken during isolation/hotplug,override the affinity to online and
un-isolated CPUs from the default affinity CPUs. If no such CPU
is available, then only override with cpu_online_mask.

With commit bfc60d474137 ("genirq: Use irq_set_affinity_locked to change
irq affinity"), affinity listeners receive the notification when the irq
affinity is changed during migration. If there is no online and
un-isolated CPU available from the user specified affinity, the affinity
is overridden with all online and un-isolated CPUs. The same cpumask is
notified to PM QOS affinity listener which applies PM_QOS_CPU_DMA_LATENCY
vote to all those CPUs. As the low level irqchip driver sets affinity to
only one CPU, do the same while overriding the affinity during migration.
