[$] 5.7 Merge window part 2

By the end of the 5.7 merge window, 11,998 non-merge changesets hadbeen pulled into the mainline repository for this development cycle. Thatis 1,218 more than were seen during the 5.6 merge window; it wouldappear that current world events have not succeeded in slowing down thekernel community - at least, not yet. The latter half of the merge windowtends to see more fixes and fewer new features, but there are still anumber of interesting things that showed up after the first-half summary was written.
