Sounds much better to me. Wouldn't something along the lines of this make the most sense: #ifdef __ARCH_PIT_FREQ # define PIT_FREQ __ARCH_PIT_FREQ #else # define PIT_FREQ 1193182 #endif After all, it seems like the vast majority of legacy-compatible hardware _do_ use the standard frequency. --david - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
