See r215706, that was a followup to the commit. Without it, stable/8
is broken:

/usr/bsd/src/sys/modules/linux/../../compat/linux/linux_emul.c: In function 'linux_proc_exec':
/usr/bsd/src/sys/modules/linux/../../compat/linux/linux_emul.c:265: error: dereferencing pointer to incomplete type
/usr/bsd/src/sys/modules/linux/../../compat/linux/linux_emul.c:265: error: 'SV_ABI_MASK' undeclared (first use in this function)
