Yeah I wasnt particularly happy about where I put the override.
skbuff.h directly includes:

#include <asm/atomic.h>
#include <asm/types.h>

...

#include <asm/system.h>

system.h gets included way down in the file, so I picked system.h as the 
most reasonable of the three. Im open to ideas as to how to make this neater.
