Rick Edgecombe ab5130186d x86/mm/cpa: Flush direct map alias during cpa ... As an optimization, cpa_flush() was changed to optionally only flush the range in @cpa if it was small enough. However, this range does not include any direct map aliases changed in cpa_process_alias(). So small set_memory_() calls that touch that alias don't get the direct map changes flushed. This situation can happen when the virtual address taking variants are passed an address in vmalloc or modules space. In these cases, force a full TLB flush. Note this issue does not extend to cases where the set_memory_() calls are passed a direct map address, or page array, etc, as the primary target. In those cases the direct map would be flushed.
