Editing Linux 3 on PS3

[[Category:Linux]]
=Introduction=

* Linux 2.6 series is nearing EOL.  Only LTS kernels continue to receive security updates, but no new features.  New drivers are available only on Linux 3.
* Linux 3 is stable and works on PS3 Slim without problems.

=Compilation dependencies=

Glevand provides Linux 3 kernel patches at: http://gitorious.ps3dev.net/ps3linux<br />
Sample .config file: plan to post at pastebin
