[PATCH 0/4] module: force sh_addr=0 for arch-specific sections

[Petr Pavlu <petr.pavlu@suse.com>]

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.
