- * Did we relocate the ramdisk?

- * So we possibly relocate the ramdisk *after* applying microcode on the
- * BSP so we rely on use_pa (use physical addresses) - even if it is not
- * absolutely correct - to determine whether we've done the ramdisk
- * relocation already.
+ * Fixup the start address: after reserve_initrd() runs, initrd_start
+ * has the virtual address of the beginning of the initrd. It also
+ * possibly relocates the ramdisk. In either case, initrd_start contains
+ * the updated address so use that instead.
