Subject: [PATCH 01/11] ia64: Convert local_softirq_pending() to per-cpu ops
Date: Tue, 8 May 2018 15:38:16 +0200 [thread overview]
Message-ID: <1525786706-22846-2-git-send-email-frederic@kernel.org> (raw)
In-Reply-To: <1525786706-22846-1-git-send-email-frederic@kernel.org>
In order to consolidate and optimize generic softirq mask accesses, we
first need to convert architectures to use per-cpu operations when
possible.
