Which header file?

[Amit Kumar]

Hi,
In linux/include/linux/atomic.h, there are two files included asm/atomic.h
and asm/barrier.h. Both files are present in linux/include/asm-generic and
linux/arch/arm/include/asm. If I build like,
CROSS_COMPILE=arm-linux-gnueabi- ARCH=arm make zImage dtbs
then which file is being used.

A kernel newbie,
Amit Kumar
