| H A D | pgalloc.h | d9e9a641 Mon Dec 04 08:07:39 CST 2017 Dave Hansen <dave.hansen@linux.intel.com> x86/mm/pti: Allocate a separate user PGD
Kernel page table isolation requires to have two PGDs. One for the kernel,
which contains the full kernel mapping plus the user space mapping and one
for user space which contains the user space mappings and the minimal set
of kernel mappings which are required by the architecture to be able to
transition from and to user space.
Add the necessary preliminaries.
