Andrew Boie 2cfeba8507 x86: implement interrupt stack trampoline ...

Upon hard/soft irq or exception entry/exit, handle transitions
off or onto the trampoline stack, which is the only stack that
can be used on the kernel side when the shadow page table
is active. We swap page tables when on this stack.

Adjustments to page tables are now as follows:

- Any adjustments for stack memory access now are always done
  to the user page tables

- Any adjustments for memory domains are now always done to
  the user page tables

- With KPTI, resetting a page now clears the present bit
