Linux 6.13-rc6

Linux 6.13-rc6

[Linus Torvalds]

So we had a slight pickup in commits this last week, but as expected
and hoped for, things were still pretty quiet. About twice as many
commits as the holiday week, but that's still not all that many.

I expect things will start becoming more normal now that people are
back from the holidays and are starting to recover and wake up from
their food comas.

In the meantime, below is the shortlog for the last week. Nothing
particularly stands out, the changes are dominated by various driver
updates (gpu, rdma and networking), with a random smattering of fixes
elsewhere.

Something not well baked managed to sneak in and it is tagged for stable:

adcfb264c3ed ("vmstat: disable vmstat_work on vmstat_cpu_down_prep()")

Reverting it fixes the warn splat below.
