Linux godfather Linus Torvalds has certified that the official Linux kernel 3.10 is now in its final state; and, as far as our audience is concerned, the big addition to the Linux kernel is with enhanced ARM processor support. Specifically, the Linux kernel 3.10 has added support for big.LITTLE processors, which should help developers port Ubuntu Touch to the Samsung Galaxy S4 and other devices.
Ubuntu 13.10 has been planned to run on the Linux kernel 3.10, and Ubuntu 13.10 is going to be the version number of the first set of Ubuntu Touch phones. This means that as soon as the final build of the 3.10 Linux kernel is folded into the Ubuntu dailies, work will be able to begin on finally bringing support for Ubuntu Touch to the international Samsung Galaxy S4, which runs on the Samsung Exynos Octa 5. As yet there hadn't been any work to bring Ubuntu Touch to Samsung's new flagship, because right now the daily builds of Ubuntu Touch are based on Ubuntu 13.04
The addition of big.LITTLE support could also make it easier for future Android devices and even Chrome OS devices to run on big.LITTLE processors, because Android manufacturers won't have to build in support for the processors.
