Heh. Right.

I hadn't thought of that use-case as the vehicle to create the
payload is 'dracut'. And its mechanism is to prepend the uncompressed
cpio with microcode to the compressed cpio with normal initramfs.

Thought of course there is nothing stopping to have an compressed
initramfs _with_ the microcode blobs.

I will put this on the Xen 4.6 roadmap.

P.S.
Thought let me double-check that 'dracut' does not compress - it was
not doing that in Fedora 20.
