Log message:
        Implement a functional vmalloc(). THe vmalloc range address translations
        are stashed in an array of page tables, starting from kptbl[]. The fast
        tlbmiss handler quickly checks to see if the faulting address is in the
        vmalloc range, and if so, it uses the translations in the kptbl to 
update
        the tlbs. Still to do: tlb invalid faults in the vmalloc range needs to
        be handled properly.
