Kernel prepatch 6.0-rc7

The 6.0-rc7 kernel prepatch is out for
testing.

So I was thinking rc7 might end up larger than usual due to travel
hitting rc6, but it doesn't really seem to have happened.

Yeah, maybe it's marginally bigger than the historical average for
this time of the release cycle, but it definitely isn't some
outlier, and it looks fairly normal. Which is all good, and makes
me think that the final release will happen right on schedule next
weekend, unless something unexpected happens. Knock wood.
