This looks like a good idea on multiple levels. We can take it through tip, but one things that makes me nervous is that neither of the "CHAR and MISC DRIVERS" supporters are even on cc.

I guess arm and powerpc have cc_platform_has() so it's not _completely_ x86 only, either. Acks from those folks would also be appreciated since it's going to affect them most immediately.
Also, just to confirm, patch 2 can go to stable@ without _any_ dependency on patch 1, right?
