The only benefit of kexec_file_load is that it is simple enough from a kernel perspective that signatures can be checked. kexec_load in every other respect is the more capable and functional interface. It makes no sense to get rid of it. It does make sense to reload with a loaded kernel on memory hotplug. That is simple and easy. If we are going to handle something in the kernel it should simple an automated unloading of the kernel on memory hotplug. I think it would be irresponsible to deprecate kexec_load on any platform. I also suspect that kexec_file_load could be taught to copy the dtb on arm32 if someone wants to deal with signatures. We definitely can not even think of deprecating kexec_load until architecture that supports it also supports kexec_file_load and everyone is happy with that interface. That is Linus's no regression rule. Eric
