Kernel prepatch 6.19-rc1

Linus has released 6.19-rc1, perhaps a bitearlier than expected.

So it's Sunday afternoon in the part of the world where I am now,so if somebody was looking at trying to limbo under the mergewindow timing with one last pull request and is taken by surpriseby the slightly unusual timing of the rc1 release, that failed.

Teaching moment, or random capricious acts? You be the judge.
