There is code to adjust the mapping down if a mmap fails
at a physical address. However, if the address is less
than the page size of the system then the physical offset will
underflow. This can actually cause a kernel panic on when
operating on /dev/mem.
The failing condition happens when the requested mapping at 0
fails in the kernel. The fallback path is taken and page size
is subtracted from 0 making a very large offset. The PAT code
in the kernel fails with a BUG_ON in reserve_memtype() checking
start >= end. The kernel needs to be fixed as well, but this
fallback path is wrong as well.

Start-point is Gigabyte GA-G41M-ES2L.
This board features a G41 northbridge and an ICH7 southbridge. This
board has slots for both DDR2 and DDR3 (cannot run concurrently
though) but only DDR2 is implemented in coreboot. The SPI flash
resides in a DIP-8 socket.
Tested and working:
* DDR2 dual channel (PC2 5300 and PC2 6400, though raminit is picky
with assymetric dimm setups);
* 3,5" IDE;
* SATA;
* PCIe x16 (with some patches up for review);
* Uart, PS2 Keyboard;
* USB, ethernet, audio;
* Native graphic init;
* Fan control;
* Reboot, poweroff, S3 resume;
* Flashrom (vendor and coreboot).
Tested but fails:
* DDR3 (not implemented in coreboot).
Tests were run with SeaBIOS and Debian sid, using Linux 4.9.0.

`cardF[n]` should indicate whether the DIMM in channel n is of
raw card type F. However, `cardF[1]` was initialised with the
value meant for `cardF[0]`. This patch results in the correct
initialisation of `cardF`.
Tested on a Lenovo T400 containing two DIMMs: one of raw card
type F and the other of raw card type B. Before the patch, the
system would not boot. After the patch, the system boots with all
of the memory functional.

The thinkpad-acpi driver uses the UCMS (CMOS) ACPI method to control the
ThinkLight from the Operating System. This patch adds partial support for
that method, enough to enable or disable the ThinkLight:
echo on >/proc/acpi/ibm/light
echo off >/proc/acpi/ibm/light
With the original BIOS the UCMS method exposes a wide range of values
through a generic /proc/acpi/ibm/cmos interface. With the changes suggested
in this patch that interface is also exposed but only accepts the commands
to enable or disable the ThinkLight; all other commands are ignored.
This change would potentially benefit all currently supported Thinkpad
models, I only have an X201 available for tests though.
