4 * This include file implements the atomic operations for arm and defines
5 * atomic data types which are used by the atomic operations API file. This
6 * file should use fixed name cpuatomic.h and should be included in atomic
7 * operations API file atomic.h. If the architecture works at the UP mode it
8 * will use a generic atomic ops using disable/enable-IRQ simulated. If the
9 * the architecture works at SMP mode, most of the parts of implementations
10 * are imported from FreeBSD kernel.
