-
-xchg() primitives has been rewritten from a MIT-licensed cmpxchg for Intel
-and powerpc. They are MIT-licensed and therefore usable in LGPL code.
-This cmpxchg code was obtained from the atomic_ops project:
-
-       http://www.hpl.hp.com/research/linux/atomic_ops/
-
-I (Mathieu Desnoyers) wrote the remainder of the code.
-
-The license for the library files in this project was therefore changed to
-LGPLv2.1 on May 13, 2009, as detailed in LICENSE.
