/* Note: The header files were taken from the source of the BSD kernel. More architectures than listed below are supported by BSD. To add another atomic.h for an architecture ${ARCH}, simply copy the atomic.h file which is located in the sys/${ARCH}/include directory of the kernel source tree. You'll also need any files from that directory on which atomic.h depends, and you'll probably have to slightly adapt the files. */
