Why are CONFIG_LOCKDEP_SUPPORT, CONFIG_TRACE_IRQFLAGS_SUPPORT, and CONFIG_STACKTRACE_SUPPORT not defined for PowerPC?
These three Kconfig options:
CONFIG_LOCKDEP_SUPPORT
CONFIG_TRACE_IRQFLAGS_SUPPORT
CONFIG_STACKTRACE_SUPPORT
Are not defined for ppc or powerpc, but they are defined for several other architectures. I'm trying to debug some semaphore locks in ALSA, and these defines are necessary to enable some other Kconfig features.

These work for me, but I don't think they're finalised yet so your mileage may vary:

FWIW, the second one doesn't work on my quad G5 but I have a version that works... Haven't figured out yet what's wrong with this one.
