Linux Linus Torvalds included patches into the mainline tree which implement a stable userspace driver API into the Linux kernel. The stable driver API was already announced a year ago by Greg Kroah-Hartman. Now the last patches were uploaded and the API was included in Linus' tree. The idea of the API is to make life easier for driver developers: "This interface allows the ability to write the majority of a driver in userspace with only a very small shell of a driver in the kernel itself. It uses a char device and sysfs to interact with a userspace process to process interrupts and control memory accesses."

I think it has more to do with politics than anything else.

Linus and kernel developers were not really enthusiastic about GPLv3 and its restrictions. This way kernel gets out with model that is even more free (just as Linus was ranting not so long ago) than before even if they would relicense it as GPLv3. Linus has shown a lot of willfulness towards companies developing drivers for linux and this would be it. But without ABI stability there are still needs for source to be recompiled for each kernel version (or at least wrapper part).
