David Hildenbrand 1da530fe15 kasan: fix memory hotplug during boot ... commit 3f19597215 upstream. Using module_init() is wrong. E.g. ACPI adds and onlines memory before our memory notifier gets registered. This makes sure that ACPI memory detected during boot up will not result in a kernel crash. Easily reproducible with QEMU, just specify a DIMM when starting up.
