/*
 * This file provides wrappers with KASAN instrumentation for atomic operations.
 * To use this functionality an arch's atomic.h file needs to define all
 * atomic operations with arch_ prefix (e.g. arch_atomic_read()) and include
 * this file at the end. This file provides atomic_read() that forwards to
 * arch_atomic_read() for actual atomic operation.
 * Note: if an arch atomic operation is implemented by means of other atomic
 * operations (e.g. atomic_read()/atomic_cmpxchg() loop), then it needs to use
 * arch_ variants (i.e. arch_atomic_read()/arch_atomic_cmpxchg()) to avoid
 * double instrumentation.

 * Originally we had the following code here:
 *     __typeof__(p1) ____p1 = (p1);
 *     kasan_check_write(____p1, 2 * sizeof(*____p1));
 *     arch_cmpxchg_double(____p1, (p2), (o1), (o2), (n1), (n2));
 * But it leads to compilation failures (see gcc issue 72873).
 * So for now it's left non-instrumented.
 * There are few callers of cmpxchg_double(), so it's not critical.
