ARM: Remove address checking for MMUless devices
Commit 169f9102f9198b ("ARM: 9350/1: fault: Implement
copy_from_kernel_nofault_allowed()") added the function to check address
before use. However, for devices without MMU, addr > TASK_SIZE will
always fail. This patch move this function after the #ifdef CONFIG_MMU
statement.
