Re: [PATCH] x86: set Pentium M as PAE capable
great to see that we have an enhaced version of the initial quick`n`dirty patch now. i just tested it on ubuntu 13.10 with kernel from 14.04 repository (complete package build). works as expected ! hopefully ubuntu #930447 can now be closed soon and the patch will quickly find it´s way into trusty tahr. this is important, because windows xp is EOL`ed on 8th of april, and there will probably be lot`s of users with older notebooks try switching to lubuntu/xubuntu or whatever "PAE-only distro". ( https://wiki.ubuntu.com/TrustyTahr/ReleaseSchedule ) i would recommend adding the newly introduced param to Documentation/kernel- parameters.txt , though. Thanks for your work !

Good point, patch updated to not show the warning if PAE is already enabled.
