110 * - Kernel is loaded at 64MB boundary
111 * - All PID registers are set to the same value

120 * - Make sure it's protected, invalidate other entries

122 * - Switch to temp mapping
123 * - Map 64MB of RAM in TLB1[1]
124 * - Use AS=0, set EPN to VM_MIN_KERNEL_ADDRESS and RPN to kernel load address
