CONFIG_MAXPHYSMEM_* are actually never used, even the nommu defconfigs selecting the MAXPHYSMEM_2GB had no effects on PAGE_OFFSET since it was preempted by !MMU case right before.
In addition, the move of the kernel mapping at the end of the address space broke the use of MAXPHYSMEM_2G with MMU since it defines PAGE_OFFSET at the same address as the kernel mapping.
