Kernel prepatch 6.6-rc1

Linus has released 6.6-rc1 and closed the
merge window for this release.

All the stats for 6.6 look fairly normal so far - as always, the
bulk of the patch is drivers (a bit of everything, but networking
and gpu are the two biggest areas), with arch updates coming in as
a notable second, and then we have tooling and documentation.
