If it's nonzero, ARM's 2.6.23 may interpret it as being an ATAGS pointer. And when that happens, the system prefers the ATAGS over CONFIG_CMDLINE. There's sanity checking in __vet_atags, but maybe it isn't enough. Other than that, I can't see anything yet. b.g. -- Bill Gatliff bgat@billgatliff.com - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
