Hi Linus,

Please pull these execve fixes for v6.8-rc2. One change was sent as part
of the original -rc1 PR, one is a recent fix, and the rest are cleanups
related to moving the open() earlier. I was waiting for a couple -next
cycles since -rc1, and since we were already working on the in_execve fix,
I figured I should send this PR now too.

Thanks!

-Kees
