Get hold of a copy of ARM's "ELF for the ARM® Architecture" document. 
It is available from ARM, but I also found older versions of it at 
various places on the web.  I recommend going directly to ARM:

http://infocenter.arm.com/help/topic/com.arm.doc.ihi0044c/IHI0044C_aaelf.pdf

Look at table 4-7 in section 4.6.1.1 where it defines R_ARM_REL32 as:

  R_ARM_REL32  ((S + A) | T) – P

This section also documents the meanings of S, A, T and P.  All you have 
to do is to implement this in the kernel.  It should be pretty 
straightforward.  The relocation is basically the same as the 
R_ARM_ABS32 relocation, except that it is location-relative.

Cheers
