Subject: [PATCH v5 06/12] arm/mem_access: Introduce GV2M_EXEC permission
Date: Tue, 27 Jun 2017 13:52:14 +0200	[thread overview]
Message-ID: <20170627115220.21066-7-proskurin@sec.in.tum.de> (raw)
In-Reply-To: <20170627115220.21066-1-proskurin@sec.in.tum.de>

We extend the current implementation by an additional permission,
GV2M_EXEC, which will be used to describe execute permissions of PTE's
as part of our guest translation table walk implementation.
