[$] The second half of the 4.17 merge window

By the time the 4.17 merge window was closed and 4.17-rc1 was released, 11,769 non-merge changesets had been pulled into themainline repository. 4.17 thus looks to be a typically busy developmentcycle, with a merge window only slightly more busy than 4.16 had.Some 6,000 of those changes were pulled after last week's summary was written. There was alot of the usual maintenance work in those patches (over 10% of thosechanges were to device-tree files, for example), but also some moresignificant changes.
