Got it, thanks. It's easier for me to delete the patches once I have them in the branch, that's been updated and now pushed to kernel org again (https://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux.git/log/?h=kmap-conversion-for-5.12) I'll add it to testing branches and let it test over the weekend, sending the pull request next week.
