I just realized, though, that this patch requires the R_ARM_REL32 from [0] as well, as there are a few rare occurrences of phys_to_virt() in module code (musb_hdrc and vivid) [0] https://lore.kernel.org/linux-arm-kernel/20200914095706.3985-4-ardb@xxxxxxxxxx/ If nobody minds, I will just fold it into the PR, as it has been reviewed and discussed already between Russel, Nico and myself.
