Merge remote-tracking branch 'scott/next' into next
Highlights include corenet board file consolidation, the ability to run
userspaces with lwsync on e500v1/v2, some cleanup patches that other KVM
patches will build on, support for stripped-down e6500 emulation targets,
and some fixes of minor longstanding issues.
