Dave, those changes hit mainline without ever having appeared in the sparc-2.6.git tree, afaict. If they _had_ appeared there I'd have been able to tell you that there wasn't any point in changing code which we're planning on deleting. Otoh, [SPARC64]: Export powerd facilities for external entities. Besides the existing usage for power-button interrupts, we'll want to make use of this code for domain-services where the LDOM manager can send reboot requests to the guest node. make me think that this code isn't deleteable any more. Ho hum, I will delete the sparc64 hunk and shall hope for the best. Mainly to avoid downstream rejects - I suspect this patch needs revisting now. Andi, your tree is looking pretty stale - I hope it will be updated soon? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
