I've also found out that the vmlinux.lds changes don't seem to be necessary - they've been the last remnant of the "old" ARM hibernation patch, but just leaving those out looks to make no difference (the nosave data still ends up in the same place, with the same elf section attributes).

It's also the case e.g. for SoCs with L2 caches as the activation sequence there is SoC-dependent; a full off-on cycle for L2 is not done by the hibernation support code. It's also the case if the SoC requires steps on wakeup _before_ the "generic" parts done by cpu_suspend / cpu_resume can work correctly.
