Without the update, we'll only see the new dmesg buffer after the reboot, but previously we could see it right away. Making an oops visible in pstore filesystem before reboot is a somewhat dubious feature, but removing it wasn't an intentional change, so let's restore it.

For this we have to make persistent_ram_save_old() safe for calling multiple times, and also extern it.
