Kernel prepatch 6.11-rc1

Linus Torvalds has released 6.11-rc1 and closed the
merge window for this development cycle. 'The merge window felt pretty
normal, and the stats all look pretty normal too. I was expecting things to
be quieter because of summer vacations, but that (still) doesn't actually
seem to have been the case.'

Note that the extensible scheduler class
('sched_ext') was not merged, even though Torvalds had said he would back in June. Sched_ext, it
seems, will need another development cycle out of tree.
