First of all a method is introduces to generate the page flag functions using macros. Then the number of page flags used by sparsemem is reduced. Then we add a way to export enum constant to the preprocessor which allows us to get rid of __ZONE_COUNT and use the NR_PAGEFLAGS for the calculation of actually available page flags for fields. Lastly there is a land grab of page flags for various ongoing VM projects. -- -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
