[RFC/PATCH LGUEST X86_64 02/13] hvvm export page utils

[Steven Rostedt <rostedt@goodmis.org>]

plain text document attachment (hvvm-mm-export.patch)
I would like to have the HV VM code in the kernel proper,
but until then, it needs to get at some of the memory page
table utils (pud_alloc and friends). So as a module, we export
this.

I probably can change HV VM to just be compiled in the kernel
like some of the other lguest stuff too.
