now that I've verified it, I see it too.  I bisected it:

    ppc: Fix roll over bug in flush_cache()
    
    If we call flush_cache(0xfffff000, 0x1000) it would never
    terminate the loop since end = 0xffffffff and we'd roll over
    our counter from 0xfffffe0 to 0 (assuming a 32-byte cache line)
    
    Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

the extra checks this patch makes makes flush_cache() consume a mere 16
more bytes, which makes the SIMPC8313 build fail.

I don't see an easy way out of this that satisfies everyone.  Ideas?
