- * Note :
- *
- * (1) SuperH does not have CMPXCHG.  It has only TAS for atomic
- *     operations.  It does not seem a good idea to implement CMPXCHG,
- *     with TAS.  So, we choose to implemnt these operations with
- *     posix mutexes.  Please be sure that this might cause performance
- *     problem for Android-SH. Using LL/SC instructions supported in SH-X3,
- *     best performnace would be realized.
- *
- * (2) Mutex initialization problem happens, which is commented for
- *     ARM implementation, in this file above.
- *     We follow the fact that the initializer for mutex is a simple zero
- *     value.
- *
- * (3) These operations are NOT safe for SMP, as there is no currently
- *     no definition for a memory barrier operation.
