From: Matt Fleming <matt.fleming@intel.com>
We've started getting reports of users seeing Machine Check Exceptions when booting their Samsung laptops in UEFI mode,
https://bugzilla.kernel.org/show_bug.cgi?id=47121
This module seems to be the culprit as it's grovelling around in the 0xf0000 region which has no mapping in either the e820 or EFI memory maps on the affected machines.
