I have the same opinion for suspend/resume too, although
in that case I know less about the issues and if we
found that it indeed does make a random driver writers
life easier[*] then it might be a reason to do this. But
I still don't think that would give boot code a license to
just revert back to "I don't know or care, GFP_KERNEL pelase"

[*] and note that being unaware of your context I don't
think is making life easier automatically.
