[Qemu-devel] [PATCH v2 09/11] target/arm: Add AIRCR to vmstate struct

From: Peter Maydell
Subject: [Qemu-devel] [PATCH v2 09/11] target/arm: Add AIRCR to vmstate struct
Date: Fri, 9 Feb 2018 16:58:08 +0000

In commit commit 3b2e934463121 we added support for the AIRCR
register holding state, but forgot to add it to the vmstate
structs. Since it only holds r/w state if the security extension
is implemented, we can just add it to vmstate_m_security.
