- The linked list of setup_data is copied to memory area right after the kernel _end during early kernel bootstrap to solve the issue that where the safe place is to place linked list of setup_data.

- Use bt_ioremap/bt_iounmap in copy_setup_data.
v4:

- Export boot parameters via sysfs.
v3:
- Move hd0_info and hd1_info back to zero page for compatibility.
