I dont see this fix in the recent kernel upload note that this is essential
else ES2.0 pandaboard will not boot anymore ...
...according to the IRC conversation below it was merged though, is there
just a changelog entry missing (we uploaded the matching x-loader patch so
booting will be broken unless the kernel patch is in too) ?

<ogra> tgardner, so if cooloneys patch hits the git tree, feel free to
upload, i just pushed the x-loader patch
<tgardner> ogra: in progress
<ogra_ac> tgardner, err, bryan just says its not in the git tree yet
<tgardner> ogra: like I said, its in progress. I'll get it pushed soon, then
upload thereafter.
<ogra_ac> ah, it just only hit the ML
<ogra_ac> ok, thanks
* ogra_ac calms down a bit :)
<tgardner> ogra, rsalveti: pushed (you'll need to rebase). I'll upload in a
<rsalveti> tgardner: cool, thanks a lot
