Are you actually using XIP in something other than QEMU? The fact that
some of the blamed fixes are over 18 months old suggests that you are
not actively using XIP builds of the mainline kernel.
There is a desire to remove XIP support (among other things), so if you
do actually have a use case for it, speak up.
