Andrew Boie 9849c7d3e7 x86: don't use privilege stack areas as a guard ... This is causing problems, as if we create a thread in a system call we will *not* be using the kernel page tables if CONFIG_KPTI=n, resulting in a crash when the later call to copy_page_tables() tries to initialize the PDPT (which is in the same page as the privilege stack). Just don't fiddle with this page's permissions; we don't need it as a guard area anyway since we have a stack guard placed immediately before it, and this page is unused if user mode isn't active.
