[PATCH v4 6/8] ACPI: HMAT: use hotplug_memory_notifier() directly

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Since patch 316346243be6 has already updated the minimum gcc version to 5.1.
The previous problem mentioned in patch f02c69680088 is not existed. So we
can now revert to use hotplug_memory_notifier() directly rather than
register_hotmemory_notifier().
