   There used to be separate two bits in my MMU project PTE to encode the   
   type and a shortcut page indicator. They were combined into a single   
   two-bit field, 0=PTE,1=PTP, and 2=shortcut. That leaves an extra unused   
   code. I am wondering what to use the code for. The only thing I can   
   think of ATM is a meta-data record indicator.   
      
   I have also been considering PTEs that are not a power-of-two in size.   
   For instance, 48-bits or possibly 56 bits. The PTEs would be stored in   
   the last part of a page with a page header and other information at the   
   beginning of the page. For an 8kB page the last (or middle) 6kB would be   
   PTEs. IDK what the header would be used for, other than perhaps some   
   sort of error management. That is, if the first part or the last part of   
   the page was overwritten, it could generate an error. Same as a header   
   on a block of memory.
