Given that, I would create a function called tboot_setup_suspend() or
something like that and localize the setting of mac_regions as well as
s3_resume_vector there.

Since it looks like s3_resume_vector is simply set up in tboot_sleep()
before we'd call tboot_shutdown(), we can presumably simply do it all in
tboot_shutdown().

Ingo, Shane: how does the attached patch look?
