Subject: [PATCH 00/10] softirq: Consolidate and optimize softirq mask

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,
