This is certainly required in the uapi header as of this patch,
without it all the numbers are wrong when you include the
file from user space.

I suppose it can be removed later once the header is replaced
with the two generated versions,

I'm fairly sure this also needs to remain in the uapi/asm/unistd.h header
as a start, so that user space can call the sys_kern_features() system
call and interpret its result when only the first patch is applied.

This part is fine.
