A bunch of hotfixes, all affecting mm/.
The 2-patch series from Andrea may be controversial. This restores
patches which were reverted in Dec 2018 due to a regression report.
After extensive discussion it is evident that the problems which these
patches solved were significantly more serious than the problems they
introduced. I am told that major distros are already carrying these
two patches for this reason.
