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 Signed-off-by: Andrew Boie <andrew.p.boie@intel.com>
