Hi hackers,

Here is a new version of the patchset. The changes compared to v14 are
minimal. Most importantly, the GCC warning reported by cfbot was
(hopefully) fixed. The patch order was also altered, v15-0001 and
v15-0002 are targeting PG15 now, the rest are targeting PG16.

Also for the record, I tested the patchset on Raspberry Pi 3 Model B+
in the hope that it will discover some new flaws. To my
disappointment, it didn't.
