Ah, you have versioned modules / builds enabled, that's what caused the rebuild, if you disable CONFIG_MODVERSIONS and CONFIG_MODULE_SRCVERSION_ALL you shouldn't rebuild everything. If those options are disabled, then something really odd is going on here... thanks, greg k-h _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
