It could. I did wonder if that made sense given that this is not a user selectable option so I'm not sure if the help will ever be visible, but I see that we do this sort of thing in Kconfig.kcsan and Kconfig.kgdb. I've changed it over. >> +# ppc64 turns on virtual memory late in boot, after calling into generic >> code >> +# like the device-tree parser, so it uses this in conjuntion with a hook in >> +# outline mode to avoid invalid access early in boot. > > I think the ppc64-related comment isn't necessary and can be moved to > arch/ppc64 somewhere, if there isn't one already. Fair enough. I'll pull it out of this file and look for a good place to put the information in arch/powerpc in a later patch/series. Kind regards, Daniel
