The IPI runs in hardirq context and there are sleeping locks. This patch
moves the completion into a workqueue.

preempt_disable() and get_cpu() don't play well together with the sleeping
locks it tries to allocate later.

+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.14/older/patches-4.14.15-rt11.tar.xz
+
+The conditions in irq_exit() to invoke tick_nohz_irq_exit() are:
+
+ if ((idle_cpu(cpu) && !need_resched()) || tick_nohz_full_cpu(cpu))
+
+This is too permissive in various aspects:
+
+ 1) If need_resched() is set, then the tick cannot be stopped whether
+ the CPU is idle or in nohz full mode.
+
+ 2) If need_resched() is not set, but softirqs are pending then this is an
+ indication that the softirq code punted and delegated the execution to
+ softirqd. need_resched() is not true because the current interrupted
+ task takes precedence over softirqd.
+
+Invoking tick_nohz_irq_exit() in these cases can cause an endless loop of
+timer interrupts because the timer wheel contains an expired timer, but
+softirqs are not yet executed. So it returns an immediate expiry request,
+which causes the timer to fire immediately again. Lather, rinse and
+repeat....
+
+Prevent that by making the conditions proper and only allow invokation when
+in idle or nohz full mode and neither need_resched() nor
+local_softirq_pending() are set.

SYSTEM_RUNNING might be too late for enabling interrupts. Allocations
with GFP_WAIT can happen before that. So use this as an indicator.

changed to local_irq_disable/save(), leading to gripes. Use nort variants.
