Or it can be a fixed address in low memory, or a scratch register in hardware.
Both will work (fixed addresses are better be avoided and who needs another PV device), but I do not see how either of them is better then patching. What is your concern?
Patching is harder to maintain. Unfortunately it's unavoidable.
Here we in agreement, and I was against patching till it was unavoidable, but than pci hotplug started using it, and afterwards processor definitions, so no point in avoiding it now by using inferior methods.
