Thomas, Ingo,

Please pull the softirq/mask-v3 branch that can be found at:

git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks.git
	softirq/mask-v3

HEAD: e225bb16aa5eb0ab83ddd0de423aca3057b1cfee

(No change since last version, just a rebase against v4.17-rc1 and
add acks from Michael Ellerman)

The softirq mask and its accessors/mutators have many implementations
scattered around many architectures. Most do the same things consisting
in a field in a per-cpu struct (often irq_cpustat_t) accessed through
per-cpu ops. We can provide instead a generic efficient version that
most of them can use. In fact s390 is the only exception because the
field is stored in lowcore.

Thanks,
	Frederic
