Kernel prepatch 5.6-rc3

The 5.6-rc3 kernel prepatch is out fortesting. Linus says: "Fairly normal rc3 as far as I can tell. We'veseen bigger, but we've seen smaller ones too. Maybe this is slightly on the low side ofaverage at this time, which would make sense since this was a smallermerge window. Anyway, too much noise in the signal to be sure eitherway."
