Sorry for pinging
I know it is busy time. But I hope to get response on these patches in 
your free time, so that I can target next merge window for this. 
(whether it has reached some good state or it is heading in reverse 
direction!). it would really boost my morale.
especially MSR stuff and dropping vcpu request bit for PV unhalt.
