The usual summary is in the tag, but the two main things to note are: (1) The bulk of the diffstat is us reverting a horrible bodge we had in place to ease the merging of maple tree during the merge window (which turned out not to be needed, but anyway) (2) The TLB invalidation fix is done in core code, as suggested by (and Acked-by) Peter.
