Subject: [PATCH 01/11] ia64: Convert local_softirq_pending() to per-cpu ops
Date: Tue,  8 May 2018 15:38:16 +0200
Message-Id: <1525786706-22846-2-git-send-email-frederic@kernel.org>
X-Mailer: git-send-email 2.7.4
In-Reply-To: <1525786706-22846-1-git-send-email-frederic@kernel.org>
References: <1525786706-22846-1-git-send-email-frederic@kernel.org>
Sender: linux-kernel-owner@vger.kernel.org
List-ID: <linux-kernel.vger.kernel.org>
X-Mailing-List: linux-kernel@vger.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.
