Subject: [PATCH v2 1/2] xen/arm: add support for vm_assist hypercall
Date: Wed, 15 Jun 2016 13:34:38 +0200	[thread overview]
Message-ID: <1465990479-20657-2-git-send-email-jgross@suse.com> (raw)
In-Reply-To: <1465990479-20657-1-git-send-email-jgross@suse.com>

Up to now the vm_assist hypercall hasn't been supported on ARM, as
there are only x86 specific features to switch. Add support of
vm_assist on ARM for future use.
