问题
in mm/memory.c, it includes one file:
#include <asm/tlb.h>
the tlb.h is include/asm-generic/tlb.h or arch/arm/include/asm/tlb.h?
回答1:
If necessary, header files in arch/arm/include/asm, will include the corresponding header file in include/asm-generic.
So in this instance, 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 that, you can identify which header file is being used.
