4.14-stable review patch. If anyone has any objections, please let me know.
------------------ From: Waiman Long <long...@redhat.com> commit 06ace26f4e6fcf747e890a39193be811777a048a upstream. The efi_pgd is allocated as PGD_ALLOCATION_ORDER pages and therefore must also be freed as PGD_ALLOCATION_ORDER pages with free_pages().
