Use
The cache or caches are to be globally invalidated, with cleaning of any writeback data being properly performed.
Notes
Note that any write buffer draining should also be performed by this operation, so that memory is fully updated with respect to any writeback data.
The OS only expects the invalidation to be with respect to instructions/data that are not involved in any currently active interrupts.
