    powerpc: Fix powerpc-specific watchdog build configuration · 75eb767e
    Nicholas Piggin authored
    The powerpc kernel/watchdog.o should be built when HARDLOCKUP_DETECTOR
    and HAVE_HARDLOCKUP_DETECTOR_ARCH are both selected. If only the former
    is selected, then the generic perf watchdog has been selected.
    
    To simplify this check, introduce a new Kconfig symbol PPC_WATCHDOG that
    depends on both. This Kconfig option means the powerpc specific
    watchdog is enabled.
    
    Without this patch, Book3E will attempt to build the powerpc watchdog.
    
    Fixes: 2104180a ("powerpc/64s: implement arch-specific hardlockup watchdog")
