Thumb-2: Add support for loadable modules
Modules compiled to Thumb-2 have two additional relocations needing to be resolved at load time, R_ARM_THM_CALL and R_ARM_THM_JUMP24, for BL and B.W instructions. The maximum Thumb-2 addressing range is +/-2^24 (+/-16MB) therefore the MODULES_VADDR macro in asm/memory.h is set to (MODULES_END - 8MB) for the Thumb-2 compiled kernel.
