Merge branch 'sparc64-vcc'
Jag Raman says:
====================
sparc64: Enable Virtual Console Concentrator (VCC)
Patchset to enable Virtual Console Concentrator (VCC). VCC provides
access to the serial console of a guest domain. It creates a RAW
VIO/LDC link between the guest domain & primary through which serial
console data is shared.
This set addresses feedback provided by Dave Miller. Cleanup of
driver state is also addressed in this set. Patches updated
are 4, 5, 6 & 7.
