It wasn't so much a hard reject as a preference based on the need presented at the time. Perhaps a generic DT driven mechanism to detect hypervisors, called early, would be more acceptable? > Stefano, Ian, any opinion? The ifdef approach is a bit ugly, but if the other option doesn't work out I suppose we can live with it. But stepping back how/why is this function called on x86 when not running under Xen? Wouldn't the use have to be using console=hvc or earlyprintk=xen or something -- which strikes me as user error... IOW can we not just nuke the check Ian. -- 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/
