ARM: 8127/1: module: add support for R_ARM_TARGET1 relocations
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.
