This is a bit of a different case than the x86 32-bit / 64-bit
problem.  The hack is contained entirely in the qemu implementation
and once we have a GDB that supports process model - or specifically
a multi-core model - it should be easy to adapt qemu.  In the mean
time, I don't see a problem with Jan's patch; it's how hardware
debuggers generally present cores to GDB at the present time.
