Merge branch 'remotes/lorenzo/pci/misc' (2021-02-24 14:59:25 -0600)
This is a resend to explain the recent dates of some of these commits.
This material has all appeared in linux-next. More details at [1],
but I fixed typos in commit logs and documentation and put a few
patches on different topic branches, resulting in recent commit dates.
The SHA1 above (e18fb64b7986) is different from yesterday's because I
added my Signed-off-by to a couple patches that I missed.
I apologize for the confusion.
