This messages is normally shown when there is an issue when comparing the processor ID (CP15 0, c0, c0) with the values/masks described in proc-v7.S. However, the same message is displayed when LPAE support is enabled in the kernel configuration, but not available in the CPU, after looking at ID_MMFR0 (CP15 0, c0, c1, 4). Having the same error message is highly misleading. This commit improves this by showing a different error message when this situation occurs: Error: Kernel with LPAE support, but CPU does not support LPAE.
