I don't mind this patch but it has made me realize
another problem.


We have both include/compiler.h and include/linux/compiler.h.
Some sources use tha former and others use the latter.

I don't know how to use the right one in the right place.

Header file policy is one of the biggest problem in U-boot.

Everyone has added ugly work-arounds to solve his own problem
without correct views or judgement.

I am not sure if likely(x) and unlikely(x) should also
duplicated here.
