OK, I don't understand git very well. When I first cloned the kernel repo, I 
did git tag -l, and I'd swear that there were only tags of the form 
v<major>.<minor>(-rc[0-9]+)? but now I give the same command again I get tags 
like v<major>.<minor>.<subminor>(-rc[0-9]+)? That's why I tried to build 3.10 
and 3.11.

I might be going mad. I know I'm tired, but this is a whole new level of 
insanity!

I'll try building 3.10.11 from git and report back.
