x86/efi: Always map first physical page into EFI pagetables (2017-01-27 20:20:01 +0000)
----------------------------------------------------------------
* Fix triple fault on boot affecting Lenovo Yoga. The firmware on
these machines will write to the zero page even though it's marked
EFI_CONVENTIONAL_MEMORY, so we must ensure it's mapped in the EFI
page tables - Jiri Kosina
