* Basic code to pull in the machine description from the Hypervisor
* An equivalent to this should really be available from mlsetup
* for really early info, but for the time being we are content to
* invoke this from startup_end once the VM system has been initialised.
* To do this we use the intrq allocator which means that
* this function should be called after intrq_init();
* We try and do this early enough however that it is useful to other
* components within the kernel.
* Also, user-level entities can grab the machine description via
