Subject: [PATCH 11/11] softirq/s390: Move default mutators of overwritten softirq mask to s390
Date: Tue,  8 May 2018 15:38:26 +0200	[thread overview]
Message-ID: <1525786706-22846-12-git-send-email-frederic@kernel.org> (raw)
In-Reply-To: <1525786706-22846-1-git-send-email-frederic@kernel.org>

s390 is now the last architecture that entirely overwrites
local_softirq_pending() and uses the according default definitions of
set_softirq_pending() and or_softirq_pending().

Just move these to s390 to debloat the generic code complexity.
