+
+If we get out of preempt_schedule_irq() then we check for NEED_RESCHED
+and call the former function again if set because the preemption counter
+has be zero at this point.
+However the counter for lazy-preempt might not be zero therefore we have
+to check the counter before looking at the need_resched_lazy flag.

There are a few local_irq_disable() which then take sleeping locks. This
patch converts them local locks.

The plain spinlock while sufficient does not update the local_lock
internals. Use a proper local_lock function instead to ease debugging.

+Subject: [PATCH] mm: perform lru_add_drain_all() remotely
+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.6/older/patches-4.6.1-rt3.tar.xz
+
+lru_add_drain_all() works by scheduling lru_add_drain_cpu() to run
+on all CPUs that have non-empty LRU pagevecs and then waiting for
+the scheduled work to complete. However, workqueue threads may never
+have the chance to run on a CPU that's running a SCHED_FIFO task.
+This causes lru_add_drain_all() to block forever.
+
+This commit solves this problem by changing lru_add_drain_all()
+to drain the LRU pagevecs of remote CPUs. This is done by grabbing
+swapvec_lock and calling lru_add_drain_cpu().
+
+PS: This is based on an idea and initial implementation by
+ Rik van Riel.

RT changes the rcu_preempt_depth semantics, so we cannot check for it
in might_sleep().

+Subject: [PATCH] sched,preempt: Fix preempt_count manipulations
+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.6/older/patches-4.6.1-rt3.tar.xz
+
+Vikram reported that his ARM64 compiler managed to 'optimize' away the
+preempt_count manipulations in code like:
+
+ preempt_enable_no_resched();
+ put_user();
+ preempt_disable();
+
+Irrespective of that fact that that is horrible code that should be
+fixed for many reasons, it does highlight a deficiency in the generic
+preempt_count manipulators. As it is never right to combine/elide
+preempt_count manipulations like this.
+
+Therefore sprinkle some volatile in the two generic accessors to
+ensure the compiler is aware of the fact that the preempt_count is
+observed outside of the regular program-order view and thus cannot be
+optimized away like this.
+
+x86; the only arch not using the generic code is not affected as we
+do all this in asm in order to use the segment base per-cpu stuff.

Disable extra stacks for softirqs. We want to preempt softirqs and
having them on special IRQ-stack does not make this easier.

+Trace events like raw_syscalls show always a preempt code of one. The
+reason is that on PREEMPT kernels rcu_read_lock_sched_notrace()
+increases the preemption counter and the function recording the counter
+is caller within the RCU section.
