Subject: [PATCH 00/10] softirq: Consolidate and optimize softirq mask v2
Date: Sat, 31 Mar 2018 05:34:43 +0200 [thread overview]
Message-ID: <1522467293-7320-1-git-send-email-frederic@kernel.org> (raw)
Only the last patch has changed since v1 to integrate review from peterz.
Quote from the v1 summary:
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.

softirq/mask-v2
HEAD: cce39c380f2dbe3e92db6a018c8ba65579c6311b
Thanks,
Frederic
