 * This is the preliminary code for controlling paging mechanism on ia32. It is
 - 
 
43 
 * needed by other parts of the kernel for its ability to map virtual addresses
 - 
 
44 
 * to physical. SMP code relies on this feature. Other than that, this code is
 - 
 
45 
 * by no means meant to implement virtual memory in terms of swapping pages in
 - 
 
46 
 * and out.
