The CPU used in Marvell Dove SoCs is a PJ4 Sheeva core. Using

Hmmm, I'm getting (with dove_defconfig):
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
Looks to me like PJ4 IWMMXT support wasn't properly tested out when it
was submitted - it's possible to end up with pj4-cp0.c built without
the IWMMXT code that it depends on being built...
Russel, Jason,
do we force iWMMXt on CPU_PJ4 or should there be some #ifdef'ery if
IWMMXT is not selected?
