I'm sure this is a bit more > common.... (like kallsyms!) See dereference_function_descriptor() in lib/vsprintf.c (where it will be clear that my memory was wrong and that PPC64 is the other architecture that needs this). Perhaps this needs to be moved to some place in asm-generic so that it can be used by code like your sanity check? -Tony -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
