Reported by Peter Maydell:

At the moment (well, if you have Marc's 3.3rc1 tree with the A15 L2
cache control register bodge in it) you can boot an A15 kernel
configured without LPAE as a KVM guest, but an LPAE kernel with LPAE
enabled will not boot. This probably mostly requires supporting the
64 bit wide cp15 registers that LPAE implies.
