Modify EFER won't result in mode switch directly. After EFER.LME set, the

Hi, Avi
As Ingo suggested, I resubmit these patches to KVM. The first patch have been
accepted by tip/x86, the latter two just a following clean up.
Hope the thing goes on well when merge...
Thanks!

They are hardware specific MSRs, and we would use them in virtualization
feature detection later.

Hi, Avi
This patchset enable MSI support for KVM VT-d.
And here are only kernel space ones. The third patch would go to also goto x86
upstream.
The userspace code would looks like this:
assigned_irq_data.guest_msi_addr = *(uint32_t *)(d->msi_cap + 4);
assigned_irq_data.guest_msi_data = *(uint16

Add vtd.c to kvm-userspace/kernel/x86/Kbuild kvm-objs item should get it done.
