Am sorry to say that I had to drop the code changes from this patch, due
to the OMAP serial bugs addressed by these two patches:
http://comments.gmane.org/gmane.linux.ports.arm.omap/84729
http://www.spinics.net/lists/arm-kernel/msg196034.html
Without those two patches, OMAP4430ES2 Panda crashes after Tero's patches
are applied, with the same symptom as with the N800 crash. Applying
those two patches fixes the problem.
It would be good if you guys could ask Greg to pick up the first patch
ASAP so we can queue the second one during the early 3.7-rc time frame.
