    [PATCH] mm: add noaliencache boot option to disable numa alien caches · 3395ee05
    Paul Menage authored Dec 06, 2006
    
    
    When using numa=fake on non-NUMA hardware there is no benefit to having the
    alien caches, and they consume much memory.
    
    Add a kernel boot option to disable them.
    
    Christoph sayeth "This is good to have even on large NUMA.  The problem is
    that the alien caches grow by the square of the size of the system in terms of
    nodes."
