First of all, the current code still limits it to 896 MiB, so 512 MiB is not a significant restriction. Second, this patch only applies if "crashkernel=" is not specified, so it doesn't even apply to your situation. Third, if you have to specify "crashkernel=" that means that there is yet another problem here that should be fixed. -hpa -- 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/
