Hello all! I changed my email setup because there were serious issues with it previously and patches were not delivered to people. Hopefully it's working now. Because of that I am sending updated patches in v4, which consist of the same functionality as in v3 added with cosmetic changes to Kconfig and updated author email address. Drew gave acked and tested-by tags in [1] so I took the liberty to include them in the patches. For convenience I am including also rangediff between v3 and v4 below.
