13130,BOOST_LOCKFREE_CACHELINE_BYTES value is incorrect on s390x,mike.munday@…,timblechmann,"The file include/boost/lockfree/detail/prefix.hpp contains the following code snippet:

{{{
// PowerPC caches support 128-byte cache lines.
#if defined(powerpc) || defined(__powerpc__) || defined(__ppc__)
    #define BOOST_LOCKFREE_CACHELINE_BYTES 128
#else
    #define BOOST_LOCKFREE_CACHELINE_BYTES 64
#endif
}}}

This sets the cache line size on s390x to 64 bytes. This is incorrect, the correct size is 256 bytes. To fix we just need to add an extra #elif checking for the __s390__/ __s390x__ compiler-defined macros.",Bugs,new,To Be Determined,lockfree,Boost 1.63.0,Optimization,,,
