EFI remap 0x00000087fb830000 => (ptrval) EFI remap 0x00000087fbdb0000 => (ptrval) EFI remap 0x00000087fffc0000 => (ptrval) The physical addresses of the UEFI runtime regions will also be printed when booting with the efi=debug command line option, and the virtual addresses can be inspected via /sys/kernel/debug/efi_page_tables (if enabled). So let's just remove the lines above.
