Therefore, the recommended and only supported way of using NEON/VFP in the
kernel is by adhering to the following rules:
* isolate the NEON code in a separate compilation unit and compile it with
'-mfpu=neon -mfloat-abi=softfp';
'-march=armv7-a -mfpu=neon -mfloat-abi=softfp';
* issue the calls to kernel_neon_begin(), kernel_neon_end() as well as the calls
into the unit containing the NEON code from a compilation unit which is *not*
built with the GCC flag '-mfpu=neon' set.

help
Historically the kernel has always automatically loaded any
line discipline that is in a kernel module when a user asks
for it to be loaded with the TIOCSETD ioctl, or through other
means. This is not always the best thing to do on systems
where you know you will not be using some of the more
"ancient" line disciplines, so prevent the kernel from doing
this unless the request is coming from a process with the
CAP_SYS_MODULE permissions.
Say 'Y' here if you trust your userspace users to do the right
thing, or if you have only provided the line disciplines that
you know you will be using, or if you wish to continue to use
the traditional method of on-demand loading of these modules
by any user.
This functionality can be changed at runtime with the
dev.tty.ldisc_autoload sysctl, this configuration option will
only set the default value of this functionality.
