reported, on APs. We already did this on BSP. Otherwise, the userspace software which depends on the features reported by the high CPUID levels is misbehaving. In particular, AVX detection is non-functional, depending on which CPU thread happens to execute when doing CPUID. Another victim is the libthr signal handlers interposer, which needs to save full FPU extended state.
