Essentially, yes. The BIOS fix isn't available on UV1, but that's older hardware at this point, and the distro kernels that run on it will still have the quirk. This change is mainly so that we can get the un-quirked code pulled in for the next major distro release. We won't be checking this down into the stable branches. Mainly just planning ahead here for future UV and distro releases. - Alex -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
