> It's an old family fh processor (CPUID 00020F42) that cpu_has_amd_erratum(amd_erratum_400) apparently hasn't picked up. Since all fh processors are affected by this erratum I'll replace "c->x86 >= 0xf" with "c->x86 > 0xf" (and probably fix erratum formula anyway). Hi, what's the status of this please? I don't see the fix neither in the -next tree. thanks, -- js _______________________________________________ stable mailing list [email protected] http://linux.kernel.org/mailman/listinfo/stable
