Can he really promise all CPUs?

Promising that a driver will work on all CPU architectures is easier said than done. For example, I recall Daniel Jacobowitz' work on the Debian PPC stock kernel a few years ago, where he painstakingly enabled options one by one and recompiled to determine which would even *compile*, let alone run correctly. And PPC is a relatively popular architecture among Linux users, much more than e.g. PA-RISC, S-390 or SuperH.

Things have improved a lot since Linux started using git. Besides, making one driver compile for all architectures is not that hard. The hard part is making all (or many) drivers compile for a given CPU.
