Having thought about this for a bit, I have come to the conclusion that it would be a lot cleaner to use a new TLF_SLEEPING bit rather than having to read HID0 to know whether we were napping or sleeping. There are plenty of bits left in thread_info.local_flags; we've only used 1 so far. :) Paul. _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
