    Subject[PATCH 5/7] alpha: kill unnecessary __used attribute in PER_CPU_ATTRIBUTES
    Date
    With the previous percpu variable definition change, all percpu
    variables are global and there's no need to specify __used, which only
    triggers on recent compilers anyway. Kill it.

    [ Impact: remove unnecessary percpu attribute ]
