possibly get_dr7).
fix the 'vcpi' typos when apic_debug is enabled.

Hi Marcelo,
Could you please pull the following tag into kvm/next?
It contains the long overdue GIC+timer save/restore interface for
KVM/arm, and a couple of other less important changes for KVM/arm64.
Thanks,

Hi
I had saw that user-space vhost is being developed, It is really a great
job, I had tried to do same work but failed.
I want to do same test for estimating benefit of it.
Is there any vhost-api that demo-thread could call?
Or Is there any test result that could see?

Linus,
Please pull from
git://git.kernel.org/pub/scm/virt/kvm/kvm.git master
To receive the following KVM bug fixes
Jan Kiszka (2):
KVM: x86: Fix APIC map calculation after re-enabling
KVM: nVMX: Unconditionally uninit the MMU on nested vmexit
arch/x86/kvm/lapic.c |8
With CONFIG_INTERMIX_VMALLOC it is no longer the case that all
vmalloc is contained between VMALLOC_START and VMALLOC_END.
Some portions of code still rely on operating on all those regions
however. Use for_each_potential_vmalloc_area where appropriate to
do whatever is necessary to those regions.
Hi,
I'm trying archlinux using virt-manager. When I create the veritual
machine, it asks OS type and Version, which does not have archlinux in
the dropdown list. Why is it important to specify the OS type and
Version? For archlinux, should I just select Generic for both OS type
and Version?
