(resend) RFC/Patch xmon pte/pgd/ userspace address additions

Hi Folks,

This is a resend.  I didnt see this on the patch page, so suspect it got 
lost.  (Do updated patches need to be sent to the list under a different 
thread?)

Hi All,
    here's a revised version of my initial patch.

- I've removed the try_spinlock code;
- As an alternative to duplicating lots of function to add mread calls
in place of references, I've added setjmp(bus_error_jmp) {} around what
seem more likely to be critical areas.
- cleaned up spacing
- changed most of the function names to be xmon_xxx instead of wm_xxx.

these functions show up under a submenu 'w'.   use "w?" at xmon> prompt
to get the help blurb.
