Hi Vladimir,

I support your plan and I will help this to go forward for 9pfs, PowerPC
and XIVE. I'll start with pushing the preparatory patch for 9pfs to my
9p-next branch right away.

PS: my ISP's mail relay was unhappy with the huge recipient list, so I've
    dropped all Cc: except qemu-devel. Sorry if some of the original
    recipients receive multiple copies of my previous mail...
