    ARM: 8127/1: module: add support for R_ARM_TARGET1 relocations · 55f0fb6a

    Kernel module build with GCOV profiling fails to load with the
    following error:
    
     $ insmod test_module.ko
       test_module: unknown relocation: 38
       insmod: can't insert 'test_module.ko': invalid module format
    
    This happens because constructor pointers in the .init_array section
    have not supported R_ARM_TARGET1 relocation type.
    
    Documentation (ELF for the ARM Architecture) says:
        "The relocation must be processed either in the same way as R_ARM_REL32 or
         as R_ARM_ABS32: a virtual platform must specify which method is used."
    
    Since kernel expects to see absolute addresses in .init_array R_ARM_TARGET1
    relocation type should be treated the same way as R_ARM_ABS32.
