Subject: [PATCH 0/3] FPU detection in C, second try

From: Borislav Petkov <bp@...e.de>

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.
