Applied to kvm-x86 next. I tweaked the commits to exclude the new tests from
the base VMX test, i.e. added:
-vmx_basic_vid_test -vmx_eoi_virt_test -vmx_posted_interrupts_test
to not duplicate coverage, and so that only the dedicated vmx_posted_intr_test
config fails.
I am hoping that landing vmx_posted_intr_test motivates me (or someone) to
actually fix that issue.
