It turns out that many compilers don't show section warnings on ARM currently because handling for ARM_CALL relocs are missing from modpost.c.
Based on commit c2e26114 ([ARM] 3205/1: Handle new EABI relocations when loading kernel modules) it seems that R_ARM_PC24, R_ARM_CALL and R_ARM_JUMP24 can be handled the same way. As modpost.c includes elf.h, we need to also consider that at least Debian libc6-dev is missing defines for both R_ARM_CALL and R_ARM_JUMP24 in /usr/include/elf.h. So for now let's just use the numbers in modpost.c.
