--- Comment #4 from Ed Maste <emaste@freebsd.org> ---
Is this a 32-bit Linux binary? linux_arch_prctl is implemented for 64-bit x=
86
Linux (in sys/amd64/linux/linux_machdep.c)

It is indeed a dummy (which will emit "syscall <name> not implemented") for
i386 and 32-bit on amd64:

sys/amd64/linux32/linux32_dummy_machdep.c:DUMMY(arch_prctl);
sys/i386/linux/linux_dummy_machdep.c:DUMMY(arch_prctl);

Note that none of this is really new with your upgrade; these syscalls were=
 not
implemented before and are still not. Just the log message is new.
