Jacob Pan from freescale is the author, so we should change this, will do. So this should show : ## DP: Patch author: Pan Jacob-r7aahq > ## DP: Upstream status: under review by benh. The patch does two things. Use hardware assist for cache flush, which seems to be ok on 744x processors, but broken on earlier G4s and G3s. And add a printk in case of some exception, so the user knows about it instead of it being silently discarded. I was under the impression that benh said that the patch was ok, but not really relevant, since it applies to code travel cases which either are not really used in the common case, or result in a dying of the kernel anyway. Don't remember all the details though. They do respond to some G4 processor errata's though. Friendly, Sven Luther
