Do you expect that > each architecture will involve a lot of work? I don't think so. The main architecture dependent components are register snapshotting and silencing of other cpus. These are not new problems to solve as other projects such as LKCD, KDB have already done this for most archs. > > And how much of the i386 implementation do you expect x86_64 can > reuse? We should be able to re-use most of the code. The x86_64 port should be ready pretty quickly once kexec itself is available.
