this patch makes room for the vcpu structure in lguest, already used in this very same way at lguest64. It's the first part of our plan to have lguest and lguest64 unified too. When two dogs hang out, you don't have new puppies right in the other day. Some time has to be elapsed. They have to grow first. In this same spirit, having these patches _do not_ mean smp guests can be launched

...st. The guest permissions for this area will obviously be restricted to DPL 0 only (guest runs in PL 3). Now what about guest data. Well, as suppose to the i386 code, we don't put any data in the hypervisor.S. All data will be put into a guest shared data structure. This structure is called lguest_vcpu. So each guest (and eventually, each guest cpu) will have it's own lguest_vcpu, and this structure will be mapped into this HV FIXMAP area for both the host and the guest in the same location. What's also nice about this, is that the host can see all the guest vcpu shared data, but each g...
