Subject: [PULL 42/51] kvm: powerpc: book3s: Add a new config variable CONFIG_KVM_BOOK3S_HV_POSSIBLE
Date: Thu, 31 Oct 2013 22:18:27 +0100 [thread overview]
Message-ID: <1383254316-11243-43-git-send-email-agraf@suse.de> (raw)
In-Reply-To: <1383254316-11243-1-git-send-email-agraf@suse.de>
From: "Aneesh Kumar K.V" <aneesh.kumar@linux.vnet.ibm.com>
This help ups to select the relevant code in the kernel code
when we later move HV and PR bits as seperate modules. The patch
also makes the config options for PR KVM selectable
