    Add huge page support to ARM64, different huge page sizes are
    supported depending on the size of normal pages:
    
    PAGE_SIZE is 4KB:
       2MB - (pmds) these can be allocated at any time.
    1024MB - (puds) usually allocated on bootup with the command line
             with something like: hugepagesz=1G hugepages=6
    
    PAGE_SIZE is 64KB:
     512MB - (pmds) usually allocated on bootup via command line.
