+Subject: [PATCH] arm: lazy preempt: correct resched condition
+
+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.

+Subject: [PATCH] kernel/printk: Don't try to print from IRQ/NMI region
+
+On -RT we try to acquire sleeping locks which might lead to warnings
+from lockdep or a warn_on() from spin_try_lock() (which is a rtmutex on
+RT).
+We don't print in general from a IRQ off region so we should not try
+this via console_unblank() / bust_spinlocks() as well.

+ context
+
+One warning should be enough to get one motivated to fix this. It is
+possible that this happens more than once and so starts flooding the
+output. Later the prints will be suppressed so we only get half of it.
+Depending on the console system used it might not be helpfull.

+Subject: [PATCH] sched,preempt: Fix preempt_count manipulations
+
+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.
