Add a config option to set the max size of a Xen domain. This is used to scale the size of the physical-to-machine array; it ends up using around 1 page/GByte, so there's no reason to be very restrictive. For a 32-bit guest, the default value of 8GB is probably sufficient; there's not much point in giving a 32-bit machine much more memory than that.

The pseudo-physical to machine address array is sized
|
|
according to the maximum possible memory size of a Xen
|
|
domain. This array uses 1 page per gigabyte, so there's no
|
|
need to be too stingy here. |
