Therefore, the recommended and only supported way of using NEON/VFP in the

* 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

built with the GCC flag '-mfpu=neon' set.

+ 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.
