Kernel prepatch 5.0-rc8

Anybody expecting the 5.0 kernel to come out today will have beendisappointed; Linus released 5.0-rc8instead. "This may be totally unnecessary, but we actually had morepatches come in this last week than we had for rc7, which just didn't makeme feel the warm and fuzzies. And while none of the patches looked all thatscary, some of them were to pretty core files, so it wasn't all just randomrare drivers (although those kinds also existed)."
