Currently the kernel audit system represents arch's as numbers and will
gladly accept comparisons between archs using >, <, >=, <= when the only
thing that makes sense is = or !=.  I'm told that the next revision of
auditctl will do this checking but this will provide enforcement in the
kernel even for old userspace.  A simple command to show the issue would
be to run

auditctl -d entry,always -F arch>i686 -S chmod

with this patch the kernel will reject this with -EINVAL

Please comment/ack/nak as soon as possible.
