    powerpc: Add kconfig for muxed smp ipi support · 1ece355b
    Milton Miller authored
    Compile the new smp ipi mux and demux code only if a platform
    will make use of it.  The new config is selected as required.
    
    The new cause_ipi smp op is only available conditionally to point out
    configs where the select is required; this makes setting the op an
    immediate fail instead of a deferred unresolved symbol at link.
    
    This also creates a new config for power surge powermac upgrade support
    that can be disabled in expert mode but is default on.
    
    I also removed the depends / default y on CONFIG_XICS since it is selected
    by PSERIES.
