Hi, after some holidays and catching up, I like to re-visit the: Pass memory ranges via e820 tables to crash kernel work. These are some cleanup patches on code I stumbled over while looking at this. It would be great if these can get applied, so that my local branch is in sync with mainline. I then like to proceed with further cleanups and finally get to the point where a clean, split up in small patches submission to implement above is possible. Thanks, Thomas
