ARM: iWMMXt: always enable iWMMXt support with PJ4 CPUs
Jason Cooper reports these build errors: arch/arm/kernel/built-in.o: In function `iwmmxt_do': /.../arch/arm/kernel/pj4-cp0.c:36: undefined reference to `iwmmxt_task_release' /.../arch/arm/kernel/pj4-cp0.c:40: undefined reference to `iwmmxt_task_switch' make: *** [vmlinux] Error 1 This is caused because the PJ4 code explicitly references the iWMMXt code, but doesn't require it to be built. Fix this by ensuring that iWMMXt is always enabled with PJ4. Reported-by: Jason Cooper <jason@lakedaemon.net> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

Enable support for iWMMXt context switching at run time if
running on a CPU that supports it.
