Modified Files:
	syssrc/sys/arch/i386/i386 [sommerfeld_i386mp_1]: locore.s pmap.c
	    vm_machdep.c
	syssrc/sys/arch/i386/include [sommerfeld_i386mp_1]: pmap.h

Log Message:
- Keep track of which CPUs are using a given pmap, and use this
  information to flush the APTE space of other CPUs as necessary.
- Use atomic operations in the appropriate places to avoid race
  conditions between the kernel and the CPU microcode which could
  lose modified/referenced information.
