From f2e207f32422c7b9624d3393db015dfd118d9d22 Mon Sep 17 00:00:00 2001 From: Vineet Gupta Date: Mon, 21 Jan 2013 17:18:57 +1030 Subject: modpost: Ignore ARC specific non-alloc sections 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 !

This also fixes missing endian corrections for some modaliases.
