Kernel prepatch 4.11-rc8

Linus has released 4.11-rc8 instead of theexpected 4.11 final. "So originally I was just planning on releasing the final 4.11 today,but while we didn't have a *lot* of changes the last week, we had acouple of really annoying ones, so I'm doing another rc releaseinstead. I did get fixes for the issues that popped up, so I couldhave released 4.11 as-is, but it just doesn't feel right."
