Linux 3.7 arrives with broader ARM support, optionally signed kernel code

Tux the Linux penguin gets his feet wet

If you're the sort of Linux user who won't even wait for a packaged distribution to update, you'll be happy to hear that Linux 3.7 has hit the servers. The updated foundation puts ARM chips on a footing much closer to that of their x86 counterparts: the code now supports a true multi-platform model that will load on multiple ARM designs. It's also the first instance of Linux to natively support 64-bit memory for newer ARM-based hardware. No matter what circuitry you're running, there's also a big boost to security by allowing signed kernel modules that will only accept approved code, even if a curious user gains root access. There are many (many, many) more tweaks and tune-ups in store, so those who like to push their OS limits can check release details from Linus Torvalds and developers at the source links.
