--- Comment #218 from Konstantin Belousov <kib at FreeBSD.org> ---
(In reply to Don Lewis from comment #216)
This is a reference to FreeBSD-SA-12:04.sysret.  We handle that by forcing
normal iret return path instead of the fast syscall return, same as we handle
any modifications to the context from usermode.  See the very end of the
amd64_syscall().
