Dear list,
I have just compiled linux-2.6.24 for a MPC8540 target using a MPC8540
specific gcc.
I then got tan infinity of "SPE used in kernel" messages. Looking at the
sources I ifdeffed out the printk call in KernelSPE, and I now have a
silent kernel, that seems to work fine.
Is there somethi

I think it's like floating point/altivec, we don't always save the FP
registers on kernel/userspace

If I were to venture a guess I'd point to the fact tha

Yeah, no idea though. I guess you could try putting that into the
arch/ppc Makefile, but arch/ppc will be removed this year so you don't
want to rely on it.
