The patches are applied to specific versions of Linux-X.Y.Z.W.
There is no tested patchset for 2.6.23, so none will be applied by default.
There are ways to apply the patches anyway.

"arch-arm" contains AT91 specific patches
"arch-avr" contain AVR32 specific patches
"linux" contain a merged patchset supporting both AT91 and AVR32.

The linux and Linux directories can be merged into one directory (linux).
There is one duplicated file for 2.6.20.4 which should be removed.
