If necessary, the header files in arch/arm/include/asm will contain the corresponding header file in include/asm-generic .

So, in this case, tlb.h is arch/arm/include/asm/tlb.h And if necessary, it will include include/asm-generic/tlb.h

You can verify this by running the following command:

 # The memory.s target creates the assembly file for memory.c make mm/memory.s

From this, you can determine which header file is being used.
