kbuild: filter away debug symbols from kernel symbols
Andi Kleen <andi@firstfloor.org> reported that he saw a lot of symbols like this: 0000000000000b24 N DW.aio.h.903a6d92.2 0000000000000bce N DW.task_io_accounting.h.8d8de327.0 0000000000000bec N DW.hrtimer.h.c23659c6.0 in his System.map / kallsyms output. Simple solution is to skip all debugging symbols (they are marked 'N'). Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Cc: Paulo Marques <pmarques@grupopie.com>
