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.

Hint 1: Check for symlinks. Hint 2: Compile with 'make V=1' which will show the complete gcc command line, so you can see the order of -I parameters.
