Hi!

This is a patch which implements an ACPI SLIT parser.
It acts as a sort of data provider.

NUMA support is a big task. The ACPI SLIT parser
is considered to be a part of the NUMA puzzle.

I have it tested on an 8-node system:

SLIT: matrix with 8 nodes
SLIT: 10 16 16 22 16 22 16 22
SLIT: 16 10 22 16 16 22 22 16
SLIT: 16 22 10 16 16 16 16 16
SLIT: 22 16 16 10 16 16 22 22
SLIT: 16 16 16 16 10 16 16 22
SLIT: 22 22 16 16 16 10 22 16
SLIT: 16 22 16 22 16 22 10 16
SLIT: 22 16 16 22 22 16 16 10
