This eliminates a lot of #ifdef SMP type code. Things like _curproc reside in a data page that is unique on each cpu, eliminating the expensive macros like: #define curproc (SMPcurproc[cpunumber()]) There are some unresolved bootstrap and address space sharing issues at present, but Steve is waiting on this for other work. There is still some strictly temporary code present that isn't exactly pretty. This is part of a larger change that has run into some bumps, this part is standalone so it should be safe. The temporary code goes away when the full idle cpu support is finished. Reviewed by: fsmp, dyson
