[$] The second half of the 4.19 merge window

By the time Linus Torvalds released4.19-rc1 and closed the merge window for this development cycle, 12,317 non-mergechangesets had found their way into the mainline; about 4,800 of thoselanded after last week's summary waswritten. As tends to be the case late in the merge window, many of those changes were fixes for the biggerpatches that went in early, but there were also a number of new featuresadded.
