- Split do_magic into swsusp_arch_suspend() and swsusp_arch_resume().
- Clean up based on pmdisk implementation
  - Only save registers we need to.
  - Use rep;movsl for copying, rather than doing each byte.
- Create swsusp_suspend and swsusp_resume wrappers for calling the assmebly
  routines that:
  - Call {save,restore}_processor_state() in each. 
  - Disable/enable interrupts in each. 
- Call swsusp_{suspend,restore} in software_{suspend,resume}
- Kill all the do_magic_* functions.
- Remove prototypes from linux/suspend.h
- Remove similar pmdisk functions.
- Update calls in kernel/power/disk.c to use swsusp versions.
