x86, fpu: remove cpu_has_xmm check in the fx_finit() CPUs with FXSAVE but no XMM/MXCSR (Pentium II from Intel, Crusoe/TM-3xxx/5xxx from Transmeta, and presumably some of the K6 generation from AMD) ever looked at the mxcsr field during fxrstor/fxsave. So remove the cpu_has_xmm check in the fx_finit() Reported-by: Al Viro <v...@zeniv.linux.org.uk> Acked-by: H.
