Subject: [PATCH -V2 14/14] kvm: powerpc: book3s: drop is_hv_enabled
Date: Mon,  7 Oct 2013 22:18:02 +0530	[thread overview]
Message-ID: <1381164482-31001-15-git-send-email-aneesh.kumar@linux.vnet.ibm.com> (raw)
In-Reply-To: <1381164482-31001-1-git-send-email-aneesh.kumar@linux.vnet.ibm.com>

From: "Aneesh Kumar K.V" <aneesh.kumar@linux.vnet.ibm.com>

drop is_hv_enabled, because that should not be a callback property
