[PATCH 1/4] module, arm: force sh_addr=0 for arch-specific sections

From: Petr Pavlu

Date: Fri Mar 27 2026 - 04:05:42 EST


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].

Force sh_addr=0 for all arm-specific module sections.
