Merge branch 'kvm-updates/2.6.33' of git://git.kernel.org/pub/scm/virt/kvm/kvm
* 'kvm-updates/2.6.33' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (84 commits) KVM: VMX: Fix comparison of guest efer with stale host value KVM: s390: Fix prefix register checking in arch/s390/kvm/sigp.c KVM: Drop user return notifier when disabling virtualization on a cpu KVM: VMX: Disable unrestricted guest when EPT disabled KVM: x86 emulator: limit instructions to 15 bytes KVM: s390: Make psw available on all exits, not just a subset KVM: x86: Add KVM_GET/SET_VCPU_EVENTS KVM: VMX: Report unexpected simultaneous exceptions as internal errors KVM: Allow internal errors reported to userspace to carry extra data KVM: Reorder IOCTLs in main kvm.h KVM: x86: Polish exception injection via KVM_SET_GUEST_DEBUG KVM: only clear irq_source_id if irqchip is present KVM: x86: disallow KVM_{SET,GET}_LAPIC without allocated in-kernel lapic KVM: x86: disallow multiple KVM_CREATE_IRQCHIP KVM: VMX: Remove vmx->msr_offset_efer KVM: MMU: update invlpg handler comment KVM: VMX: move CR3/PDPTR update to vmx_set_cr3 KVM: remove duplicated task_switch check KVM: powerpc: Fix BUILD_BUG_ON condition KVM: VMX: Use shared msr infrastructure ... Trivial conflicts due to new Kconfig options in arch/Kconfig and kernel/Makefile
