While thinking about the changes to linux/mman.h in
https://lore.kernel.org/all/20240923141943.133551-1-vincenzo.frascino@arm.com/
I ended up trying to clean up the duplicate definitions in order to
better see what's in there, and then I found a clash between two MAP_* flags.

Here is my current state, lightly tested. Please have a look at
the last patch in particular.
