You also have the patches split like 'generic / arch-1 / arch-2' which is wrong per definition, as patches should be split per change and not care about sily boundaries. Also, if you want generic entry code, there's patches for that here: https://lkml.kernel.org/r/20200722215954.464281930@linutronix.de
