I'd prefer this was done a little more sensitively to those CPUs where loads/stores are expensive, namely: > + > + @ preserve TPIDRURW register state > + get_tls2 r3, r4, r5 > + str r3, [r1, #TI_TP2_VALUE] > + ldr r3, [r2, #TI_TP2_VALUE] > + set_tls2 r3, r4, r5 those two loads/stores get omitted from the thread switching if the CPU doesn't support it. Do you think that's something you could do? -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
