Kernel prepatch 5.17-rc8

Linus has released 5.17-rc8 rather than thefinal 5.17 kernel.

Last week was somewhat messy, mostly because of embargoed patcheswe had pending with another variation of spectre attacks. Andwhile the patches were mostly fine, we had the usual "because itwas hidden, all our normal testing automation didn't see iteither".

And once the automation sees things, it tests all the insanecombinations that people don't tend to actually use or test in anynormal case, and so there was a (small) flurry of fixes for thefixes.

None of this was really surprising, but I naively thought I'd beable to do the final release this weekend anyway.

And honestly, I considered it. I don't think we really have anypending issues that would hold up a release, but on the other handwe also really don't have any reason _not_ to give it another weekwith all the proper automated testing. So that's what I'm doing,and as a result we have an -rc8 release today instead of doing afinal 5.17.
