Log Message:
Pull up following revision(s) (requested by maxv in ticket #1433):
        sys/compat/linux/arch/amd64/linux_machdep.c: 1.50, 1.51
Don't let userland choose %rip. This is the Intel Sysret vulnerability
again.
--
Make sure %rip is in userland. This is harmless, since the return to
userland is made with iret instead of sysret in this path. While here, use
size_t.
