Subject: Hibernation: Pass CR3 in the image header on x86_64

Hibernation: Pass CR3 in the image header on x86_64

Since we already pass the address of restore_registers() in the image header,
we can also pass the value of the CR3 register from before the hibernation in
the same way.  This will allow us to avoid using init_level4_pgt page tables
during the restore.
