It seems kexec/kdump on ppc don't use /proc/iomem anymore, and only rely on /proc/device-tree these days?

I think thats entirely a matter for the m68k kernel maintainers to decide. But my personal opinion is that it is nice not to add it if it isn't needed. ^ permalink raw reply [flat|nested] 2+ messages in thread
