The kernel somehow needs to know what memory areas to avoid so we supply this information via kernel command line. What the bootloader could do is to allow the kernel/initrd to be loaded at an alternative address. That's briefly mentioned in the BadRAM Documentation as well. Is that what you mean or am I missing something? Stefan -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
