- * Usage:
- * - do not go blindly adding fields, add them at the end
- * - when adding fields, don't rely on the address until
- * a patch from me has been released
- * - unused fields should be zero (for future expansion)
- * - this structure is relatively short-lived - only
- * guaranteed to contain useful data in setup_arch()
- *
- * This is the old deprecated way to pass parameters to the kernel
