Any ideas as to what is triggering this undefined instruction?
FWIW, it seems like I'm seeing the same problem here on v3.15-rc1 on Armada XP. It works fine on v3.14. Investigation in progress, but any hints would be welcome.
I haven't seen this problem reported on subsequent build reports from Olof.
In fact, the problem really existed, and doing a "make clean" didn't solve it. It is due to enabling Dove support in mach-mvebu, which causes the iWMMXt extension to be initialized on Armada XP, even though it doesn't exist.
I've reported the problem to the submitter of the patch, Cc LAKML. See http://lists.infradead.org/pipermail/linux-arm-kernel/2014-April/246994.html.
