A couple of days ago, kib@ committed a patch, r263349, that should result in AT_PAGESIZES now having a 4-byte aligned address on arm. This misalignment caused problems for a patch that I'm developing. If/when anyone here updates to a newer kernel than r263349, can you please rerun "procstat -x" and report the results. I want to verify that the alignment problem is really fixed on arm. Thanks, Alan
