Right,
here's the fixed version which boots fine on everything I have here. It would be nice if Ingo could test it on his K8 with the 32-bit MATH_EMULATION config to make sure the corruptions don't happen anymore.
The second one is the sanity check for static_cpu_has which we discussed yesterday.
And how cool is that: it already caught an unrelated issue in the FPU code which resulted in patch #3. Fun.
Thanks.
