Subject: [PATCH v7 07/15] TEMPORARY: update public headers for GICv3 ITS emulation
Date: Wed, 20 Jul 2016 18:04:27 +0100	[thread overview]
Message-ID: <20160720170435.28090-8-andre.przywara@arm.com> (raw)
In-Reply-To: <20160720170435.28090-1-andre.przywara@arm.com>

This patch is preliminary and updates the headers from a kernel with
ITS emulation and ARM GSI routing support. It should be replaced by a
proper header update once the kernel patches have been merged and all
merge conflict have been sorted out.
