It seems we're clashing with Andy's 

commit a2055abe9c6789cedef29abbdaa488a087faccc3
Author: Andy Lutomirski <luto@kernel.org>
Date:   Sun May 28 10:00:10 2017 -0700

    x86/mm: Pass flush_tlb_info to flush_tlb_others() etc

The fix should be simple but in case you want me to rebase/resend please
let me know.
