Linus Torvalds has officially announced that version 3.7 of the Linux kernel has gone stable, and that means good news for developers who work with ARM-based CPUs: among its other changes, Linux 3.7 is the first Linux kernel to include generic support for multiple ARM CPU architectures, reducing the amount of effort required to get Linux-based operating systems running on phones, tablets, and ARM-licensed developer boards like the Raspberry Pi.
