Arnd,

If you look at where this is selected, it's selected for SMP on pre-ARMv6
(okay, I doubt anyone cares about that) _or_ for uclinux on pre-ARMv6
since pre-ARMv6 can't do the vectors page trick.

So getting rid of the above takes away __thread support from userland
uclinux on these CPUs.  Is that something you really want to do?
