Merge git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux-2.6-for-linus
* git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux-2.6-for-linus: (27 commits) lguest: use __PAGE_KERNEL instead of _PAGE_KERNEL lguest: Use explicit includes rateher than indirect lguest: get rid of lg variable assignments lguest: change gpte_addr header lguest: move changed bitmap to lg_cpu lguest: move last_pages to lg_cpu lguest: change last_guest to last_cpu lguest: change spte_addr header lguest: per-vcpu lguest pgdir management lguest: make pending notifications per-vcpu lguest: makes special fields be per-vcpu lguest: per-vcpu lguest task management lguest: replace lguest_arch with lg_cpu_arch. lguest: make registers per-vcpu lguest: make emulate_insn receive a vcpu struct. lguest: map_switcher_in_guest() per-vcpu lguest: per-vcpu interrupt processing. lguest: per-vcpu lguest timers lguest: make hypercalls use the vcpu struct lguest: make write() operation smp aware ... Manual conflict resolved (maybe even correctly, who knows) in drivers/lguest/x86/core.c
