Implements SMP support in Xen on ARM. Add support for machine reboot and power off via Xen hypercalls. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) iQIcBAABAgAGBQJRe+dxAAoJEIlPj0hw4a6QSMAP/RxMT+TmQopGYLjCT2ZP7K2T qMsYzQdSwTc1Yw2ylkjd4Si1MdwtC8oqlmC9pxYXlKUBssX/kApp6tCfZuaWv1gs warV1DjgLBxM4ypEGOt/cUYZHs7MRF7XiKyAsalFzlS0lCmoS3n2IEmK+pOBqtIT zs3ObNN3jYHdkDfmY7r4+pglZa2SULGDtdUDh4iruS8S8qq28RJdvyGRtjYZa35E jUgcC5YVfKYASdDgWQdgVtP/the4JD8aqiJVA3fOvbpc4pHHpReErA3VLnK2UPzE pHyZ9J0meK0hBt4KB/s3c49v1RiruJ9aoXixhzzsn3iPerByFG/gT6G9emb7ADhm sct9mTpsUxEGwZ2YwnY6TvJAqvPmn2bycZ//rcG0orBYNJrfWk+MwSUrox3Oj/B1 adWtnNngM/zr/vC/B/NyRiNx71SrESJWCtHSuVoHJ6BxG9S7289CmfeAcOAqqn4d Vks1u8kGbQp36K6aSG8PDnp98SOHmDXoClSRtmYQdadci9DDkglvBgqlYhvi/8+z wosBfVosbfiC2FyHXIrbDr0c2bXAH1rFVVGv7s4Fr818OM/9v+bJ9g3j3m8zKQXE HAu0E5z91Y7/eDM9WFNF9v7r+beFuiXnr2w/WSCEF7mx2qToTR+iAuYGCnJ8D/Eo 2n9BHrsOIIjUXMelfckq =U5Oc -----END PGP SIGNATURE----- Merge tag '3.9-rc3-smp-6-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/sstabellini/xen Pull ARM Xen SMP updates from Stefano Stabellini: "This contains a bunch of Xen/ARM specific changes, including some fixes, SMP support for Xen on ARM, and moving the xenvm machine from mach-vexpress to mach-virt. The non-Xen files that are touched are arch/arm/Kconfig, to select ARM_PSCI on XEN, and arch/arm/boot/dts/Makefile, to build the xenvm DTB if CONFIG_ARCH_VIRT. Highlights: - Move xenvm to mach-virt. - Implement SMP support in Xen on ARM. - Add support for machine reboot and power off via Xen hypercalls" * tag '3.9-rc3-smp-6-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/sstabellini/xen: xen/arm: remove duplicated include from enlighten.c xen/arm: use sched_op hypercalls for machine reboot and power off xenvm: add a simple PSCI node and a second cpu xen/arm: XEN selects ARM_PSCI xen: move the xenvm machine to mach-virt xen/arm: SMP support xen/arm: implement HYPERVISOR_vcpu_op xen/arm: actually pass a non-NULL percpu pointer to request_percpu_irq
