The earliest version of linux which is compatible to batman-adv-kernelland is 2.6.20. Their are patches available in debian for batman-adv-kernelland 0.1 to make it build against linux 2.6.15, but they cannot be ported to current trunk due to changes to the working queues. To have "support" for much older versions isn't needed and can be removed without loosing any functionality. As result the only remaining LINUX_VERSION_CODE dependend precomiler code beside compat.h is for netdevice_ops support in soft-interface.c and result code checking of unregister_chrdev in device.c. For a possible merge into linux compat.h and all appearances of LINUX_VERSION_CODE should be removed according to checkpatch.pl.
