[$] 5.8 Merge window, part 2

By the time Linus Torvalds released 5.8-rc1and closed the merge window for this development cycle, 14,206 non-merge changesets hadbeen pulled into the repository for 5.8. That is more work thanwas pulled for the entire 5.7 cycle; clearly development work on the kernelhas not (yet) slowed down in response to events in the wider world. The nearly 6,700 changespulled since the previous summary includehuge numbers of fixes and internal cleanups, but there were a number ofsignificant features added as well.
