Subject: [PATCH 0/4] arm64: Support dynamic preemption v2

Hi,

Not much change on the core side but:

_ Use latest arm64 static call implementation by Ard
_ Rebase against latest tip:/sched/core

git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks.git
	preempt/arm-v2

HEAD: 5700542b609d9ab640210d7dd93621c7967688e6

Thanks,
	Frederic
