Impact for m68knommu:

Do you mean .rodata ?

Yes, I suspect that was the original thinking. It has been that way
for a very long time (it is in .text in the 2.4 kernel patches for
this too).
I will test them on m68knommu today, I am sure moving to .data (really
rodata) will be fine.
Doesn't that have XIP consequences? .text (and presumably .rodata) can be
stored and executed from ROM, since they can't be changed at runtime. .data
has to be in RAM, since it can be.
Yes, but even in the kernel XIP case the very early startup code
moves the kernels data to RAM. Well before the system call table
will be needed.
