	help
		Generate a warning if any W+X mappings are found at boot.

		This is useful for discovering cases where the kernel is leaving
		W+X mappings after applying NX, as such mappings are a security risk.

		Look for a message in dmesg output like this:

			arm/mm: Checked W+X mappings: passed, no W+X pages found.

		or like this, if the check failed:

			arm/mm: Checked W+X mappings: FAILED, <N> W+X pages found.

		Note that even if the check fails, your kernel is possibly
		still fine, as W+X mappings are not a security hole in
		themselves, what they do is that they make the exploitation
		of other unfixed kernel bugs easier.

		There is no runtime or memory usage effect of this option
		once the kernel has booted up - it's a one time check.

		If in doubt, say "Y".

		help
		  Semihosting enables code running on an ARM target to use
		  the I/O facilities on a host debugger/emulator through a
		  simple SVC call. The host debugger or emulator must have
		  semihosting enabled for the special svc call to be trapped
		  otherwise the kernel will crash.

		  This is known to work with OpenOCD, as well as
