-Subject: [PATCH 1/2] efi: Make 'efi_enabled' a function to query EFI
- facilities
-
-Originally 'efi_enabled' indicated whether a kernel was booted from
-EFI firmware. Over time its semantics have changed, and it now
-indicates whether or not we are booted on an EFI machine with
-bit-native firmware, e.g. 64-bit kernel with 64-bit firmware.
-
-The immediate motivation for this patch is the bug report at,
-
-    https://bugs.launchpad.net/ubuntu-cdimage/+bug/1040557
-
-which details how running a platform driver on an EFI machine that is
-designed to run under BIOS can cause the machine to become
-bricked. Also, the following report,
-
-    https://bugzilla.kernel.org/show_bug.cgi?id=47121
-
-details how running said driver can also cause Machine Check
-Exceptions. Drivers need a new means of detecting whether they're
-running on an EFI machine, as sadly the expression,
-
-    if (!efi_enabled)
-
-hasn't been a sufficient condition for quite some time.
-
-Users actually want to query 'efi_enabled' for different reasons -
-what they really want access to is the list of available EFI
-facilities.
-
-For instance, the x86 reboot code needs to know whether it can invoke
-the ResetSystem() function provided by the EFI runtime services, while
-the ACPI OSL code wants to know whether the EFI config tables were
-mapped successfully. There are also checks in some of the platform
-driver code to simply see if they're running on an EFI machine (which
-would make it a bad idea to do BIOS-y things).

-Subject: [PATCH 2/2] samsung-laptop: Disable on EFI hardware
-
-It has been reported that running this driver on some Samsung laptops
-with EFI can cause those machines to become bricked as detailed in the
-following report,
-
-	https://bugs.launchpad.net/ubuntu-cdimage/+bug/1040557
-
-There have also been reports of this driver causing Machine Check
-Exceptions on recent EFI-enabled Samsung laptops,
-
-	https://bugzilla.kernel.org/show_bug.cgi?id=47121
-
-So disable it if booting from EFI since this driver relies on
-grovelling around in the BIOS memory map which isn't going to work.
