When linking modules with 'ld.bfd -r', sections defined without an address inherit the location counter, resulting in non-zero sh_addr values in the resulting .ko files. Relocatable objects are expected to have sh_addr=0 for all sections. Non-zero addresses are confusing in this context, typically worse compressible, and may cause tools to misbehave [1]. Joe Lawrence previously addressed the same issue in the main scripts/module.lds.S file [2] and we discussed that the same fix should be also applied to architecture-specific module sections. This series implements these changes. The series can later be merged through the modules tree, or individual patches can be applied through the architecture-specific trees.
