[Qemu-devel] [PULL 1/7] pc: add 2.1 machine type

[Gerd Hoffmann]

From: "Michael S. Tsirkin" <address@hidden>

At the moment, 2.1 and 2.0 machines are identical.
As several people are working on incompatible changes
to the PC machine, collaboration will be made easier
by merging this place-holder.
