That is exactly the debate. Patrick thinks the whole thing should be
arch code and kernel/power/* just provices "library" routines to call
(like the freezer, swsusp stuff, etc...), Pavel wants to share as much
code as possible in a single place.

I have no real strong preference, I tend to be a bit more on Patrick's
side here. I can do either way, but we need to decide. On one case, I
would do a patch removing most of kernel/power/main.c and disk.c (they
are mostly redundant anyway) and replacing with a simple mecanism where
the arch provides a table of state names + function to call for sysfs.
On the other case, just merge my patch adding all the new hooks.

Ben.
