You are correct, the conversion is a bit rough and I've not yet been able to work on the powerpc vDSO, although I'd like to get it working so any help or suggestions would be appreciated (is there a reason the vDSO is written in ASM?). If you have any other concerns w/ that patch, or the generic timekeeping code, please let me know and I'll do what I can to address them. thanks -john - 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/
