If we are not going to use separate VM mapping s to keep the per-cpu
information separate any more, then can we remove the support for it from
the kernel?
examples:
i386/i386/locore.s
#ifdef SMP
/*
* Define layout of per-cpu address space.
* This is "constructed" in locore.s on the BSP and in mp_machdep.c
* for each AP. DO NOT REORDER THESE WITHOUT UPDATING THE REST!
*/
.globl SMP_prvspace, lapic
.set SMP_prvspace,(MPPTDI << PDRSHIFT)
.set lapic,SMP_prvspace + (NPTEPG-1) * PAGE_SIZE
#endif /* SMP */
why do all this page-table stuff..
now we can hust malloc the damned thing..
