Here is what I found in the forum:


To compile 100.14.09 on 2.6.23.x kernel, I made the following changes:

1. kmem_cache_create() in nv-linux.h would be one parameter less for 
2.6.23.x, take away one NULL at the end such that

#define NV_KMEM_CACHE_CREATE(kmem_cache, name, type) \
{ \
kmem_cache = kmem_cache_create(name, sizeof(type), \
0, 0, NULL); \
}

2. The 2 references to unregister_chrdev() in nv.c would return void in 
2.6.23.x.

Just take away the return code check and error message right after.


So here is my attempt at the patch.  This would be applicable to 2.6.23 
only.
