Hi Juergen,
Yesterday I wanted to test the RETPOLINE stuff in tip and tip-rt, but discovered instead that my box had turned into a complete slug, not due to incredible RETPOLINE overhead, rather because box had forgotten that it had more than one CPU. I was going to leave it for the weekend, but firing up gitk over morning java, I noticed the commits below, and sure enough, that's what broke my box. Given other people's boxen work, seems likely that the authors of the AMI BIOS in this box were a bit more creative than usual.
