I admit to be a little lost in the review thread. But it seems to me
this could be split up between formatting changes (like the \n, b, B
readelf.c one) and the actual s390_corenote.c change. Would it be
possible to post this as separate patches (and maybe even split off the
test addition if that depends on the formatting)?
here is the s390 fix depending on the readelf fix. Testcase is included,
I really do not see why to separate it.
Thanks,
Jan
