Subject: [PATCH v5 6/6] irqchip, gicv3-its: Use new jump label API
Date: Mon, 21 Sep 2015 22:58:39 +0200	[thread overview]
Message-ID: <1442869119-1814-7-git-send-email-rric@kernel.org> (raw)
In-Reply-To: <1442869119-1814-1-git-send-email-rric@kernel.org>

From: Robert Richter <rrichter@cavium.com>

Use newly introduced jump label API.

Make this a separate patch for easier backporting to older kernels of
the errata patch set.
