    x86: require x86-64 for automatic NUMA balancing · 4468dd76
    Mel Gorman 提交于
    32-bit support for NUMA is an oddity on its own but with automatic NUMA
    balancing on top there is a reasonable risk that the CPUPID information
    cannot be stored in the page flags.  This patch removes support for
    automatic NUMA support on 32-bit x86.
