This case is a bit special. I don't think it would be right to require every
device driver writer to avoid modifying RCU pages from the interrupt
context, because that would break the suspend to disk ...
Besides, if there is an RCU page that we _know_ we can use to store the image
in it, we can just include this page in the image without copying. This
already gives us one extra free page for the rest of the image and we can
_avoid_ creating two images which suspend2 does and which adds a _lot_ of
complexity to the code.
If you don't mind me asking... what are these RCU pages you speak of?
I couldn't work it out by grepping kernel/power/*
