highbank: smc change in kernel source breaks qemu booting
qemu-linaro is no longer able to boot Ubuntu's highbank kernels. I bisected this down to the following changeset in git://kernel.

UBUNTU: SAUCE: ARM: highbank: Add smc calls to enable/disable the L2
Linux runs in non-secure mode on highbank, so we need secure monitor calls
to enable and disable the PL310.

This changeset is in both the current precise and quantal kernels, so neither boot in qemu-linaro at this time. I'm filing this as a qemu-linaro bug instead of a kernel bug as these kernels boot fine on real hardware.
This is reproducible with both qemu-linaro in precise/quantal (w/ the additional highbank fixes in lp:~dannf/qemu-linaro/highbank), as well as latest qemu-linaro from git (top of tree currently at 54ec369).
