I just applied the patches tried this simple test:
 - tested with a Renesas RZ/A1 (Cortex-A9...so it has an MMU).
 - I set the sticky bit for busybox before using mkcramfs
 - booted (with squashfs) and mounted the cramfs image
 - confirmed that the sticky bit was still set on busybox
 - was able to execute busybox in the cramfs image


However, at this point I'm not sure how I can confirm that the XIP 
busybox actually executed as XIP or not.
