Are you using EFI old_memmap?
If so, then
https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/commit/?h=x86/pti&id=de53c3786a3ce162a1c815d0c04c766c23ec9c0a
("x86/pti: Unbreak EFI old_memmap") should be the cure.
If not, you might be missing this in in arch/x86/platform/efi/efi_64.c
- efi_pgd = (pgd_t *)__get_free_page(gfp_mask); + efi_pgd = (pgd_t *)__get_free_pages(gfp_mask, PGD_ALLOCATION_ORDER);
Could you please let me know if either of this fixes your problem?
Thanks,
