Kernel prepatch 5.12-rc1

Linus Torvalds has released 5.12-rc1(codename now "Frozen wasteland") andclosed the merge window despite getting a late start due to bad weather:

So I was actually without electricity for six days of the mergewindow, and was seriously considering just extending the mergewindow to get everything done.As you can tell, I didn't do that. To a large part because peoplewere actually very good about sending in their pull requests, so bythe time I finally got power back, everything was nicely lined upand I got things merged up ok.But partly this is also because 5.12 is a smaller release than someprevious ones.
