This contains parts of the ARM KVM support that have dependencies on other patches merged through the arm-soc tree. In combination with patches coming through Russell's tree, this will finally add full support for the kernel based virtual machine on ARM, which has been awaited for some time now. Further, we now have a separate platform for virtual machines and qemu booting that is used by both Xen and KVM, separating these from the Versatile Express reference implementation. Obviously, this new platform is multiplatform capable so it can be combined with existing machines in the same kernel. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIVAwUAUSUyWmCrR//JCVInAQIomBAAohivsGbHStveQpeYe8H2IH7Oa2/w1YGm x8sJEGARj/qpqKSDaMf4NJ/wcpn5AMgUqx4S4kR3p3MG5whr1Wxx7Bdl7FUPpCnY uLwD2RsEEfSHDobKIoBcrFZDFPyW+be/nAYFfBUhEUFs8VTot2i4fMhu4HdRUWCt e24ig6jHD/dMMPk0dL7SqZ/Hv/bhwhD9ZOckjKDdFlXJQ36nYWTCb6FbsAysNg+x zMV3v+cSwngJZHGu3A9oy0KR0COm6aLb5FsJrS3Ni/mYHF/O75tKJGgXkF6JiuVe DI5jtVyfT2effUH9I8R7hzkzYPi47XnOjhtZiIlGvBqhcPGu1tBxDy8+H4D0TZ94 ySUhNPutl6+BTmNjJag61hPZ66kY8yPJkpreHZdvRBZaZMSNLzMnhgdyQRzwbrDL VFDxot+zyB8KE7ffsZ2KTr+nwcVCC2XmgYhihRujn8m1u4NF2PYZOIWCuAyPaVEn zH1FztrMwXrXbHb0g4kXmZkewzqEHV2GrFzZCNkTjANTcwkB/xLcvSnloxUYGrLv URHnJbXM9FyehcY6rlSNMAdwrxa9fFMqmUb08WLv9cxHNYPBg9UN5vIGzjLfOUeK ur+i63pgtF8pYy7MaLj+Pa5g19Xk8GHWH4KEQOr6T4yz6z7gyDrjcPDi9fVFGd5E u9lP8aNKXcM= =u9F0 -----END PGP SIGNATURE----- Merge tag 'virt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM virtualization changes: "This contains parts of the ARM KVM support that have dependencies on other patches merged through the arm-soc tree.
