| |
ARC relocatable object files contain one/more .gnu.linkonce.arcextmap.* sections (collated by kernel/vmlinux.lds into .arcextmap in final link). This section is used by debuggers to display the extension instructions and need-not be loaded by target (hence !SHF_ALLOC)
The final kernel binary only needs .arcextmap entry in modpost's ignore list (section_white_list[]). However when building modules, modpost scans each object file individually, hence tripping on non-aggregated .gnu.linkonce.arcextmap.* entries as well.
Thus need for the 2 entires !
