A small pull request consisting of:

- Make rpmsg process all pending messages instead of just
   one, from Robert Tivy
 - Fix Kconfig dependency on VIRTUALIZATION, from Suman.
   Note: this was submitted late during the 3.9 rc cycle and it
   seemed appropriate to wait with it for the merge window.
 - Belated addition of an rpmsg entry to the MAINTAINERS file.
   People seem to look for this.
