Cover letter [PATCH v2 0/6] CPUID and FPU fixes
Our CPUID-less FPU detection code was terminally broken and, as far as I can tell, it's been broken for a long, long time. This series tries to improve the situation.
Changes from v1:
- Whitespace fixes
- Prettify the FPU probing code (Borislav)
- Improve logging (Borislav)
