Currently it is defined in drm/linux/Makefile on the compiler command
line. There is some magic in there to detect patched 2.4 kernels (and I
think recent stock 2.4 kernels) that have 5 remap_page_range arguments
too. If you plug the drm code into a specific kernel version you could
#define REMAP_PAGE_RANGE_5_ARGS in a suitable header file. Maybe
create_lk_drm.sh could be modified to detect the number of remap_page_range
arguments add this definition automatically if needed.
