I only know that this boots correctly since I have no system that can do 
suspend. But Ray needs an effective means of process suspension for 
his process migration patches.

Any i386 or x86-64 machine can do suspend... It should be easy to get
some notebook... [What kind of hardware are you working on normally?]

Umm... Sorry to be so negative but that has never worked for me on lots of 
laptops. Usually something with ACPI or some driver I guess... After 
awhile I gave up trying.

But is this the correct way to fix this?

It includes whitespace changes and most of patch is nice cleanup that
should probably go in separately. (Hint hint :-). 

Ok.

Previous code had important property: try_to_freeze was optimized away
in !CONFIG_PM case. Please keep that.

Obviously that will not work if we use try_to_freeze for 
non-power-management purposes. The code from kernel/power/process.c may 
have to be merged into some other kernel file. kernel/sched.c?
