So in generic include folder, if we're focusing on choosing whether COMPILE_TEST or UML, for me, I will choose COMPILE_TEST. If we're not only focusing on COMPILE_TEST, for me, if something only depend on one architecture, I'd like to put them under "arch/*/" folder. Especially, after that, we can remove all HAS_IOMEM and NO_IOMEM, nobody has to think of them again. :-) Thanks. -- Chen Gang Open, share, and attitude like air, water, and life which God blessed _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
