Isn't there a reason it was read-write on m68k, like the table may be changed
at runtime (to install rootkits :-)? Have to check what the other arches do...
Initially the syscall_table in Linux has always been writable, bb152f53
("x86/x86_64: mark rodata section read-only: make some datastructures
const") made it read-only on x86. Apparently nobody bothered to do the
equivalent change on m68k (I don't think anything makes the kernel text
segment write protected anyway).
