calling giveup_altivec on machine with no altivec!?

[Troy Benjegerdes]

My Motorola MTX just crashed after the following code in _swithc_to
executed:

	if ((prev->thread.regs && (prev->thread.regs->msr & MSR_VEC)))
		giveup_altivec(prev);


Somehow prev->thread.regs->msr & MSR_VEC turned out true. I'm suspecting
something got overwritten somewhere..

This is an SMP machine so I'm wondering if there wasn't a race condition
on something with task structs..
