    linker script: throw away .discard section · 405d967d
    Tejun Heo 提交于
    x86 throws away .discard section but no other archs do.  Also,
    .discard is not thrown away while linking modules.  Make every arch
    and module linking throw it away.  This will be used to define dummy
    variables for percpu declarations and definitions.
    
    This patch is based on Ivan Kokshaysky's alpha percpu patch.
    
    [ Impact: always throw away everything in .discard ]
