Thanks.  I queued the first three patches in mm-hotfixes-stable, as
they address post-6.13 issues which should be addressed during this -rc
cycle.

I queued the other three patches for 6.15-rcX.

I corrected the Fixes: hash in [2/6].

I made some changelog alterations, along the lines that Kairui
mentioned.  Please check the results and send along any alterations
which you feel are desirable.

Thanks for correcting the changelog. The results look good to me
except patch 1 may still need some changelog improvement. Will
send a v2 of patch 1 soon.
