It is based on yesterday's linux-next plus additional patches I used for testing. Sorry about the extra troubles, but this was the most convenient way for me, as it lets me find build regressions in random configs more easily when I have a base tree that builds randconfig warning-free.
The patches are at the top of my randconfig tree [1] at the moment, so you can try out that tree, or rebase the patches from there.
