The ARM errata 819472, 826319, 827319 and 824069 for affected Cortex-A53 cores demand to promote "dc cvau" instructions to "dc civac" as well. Attribute the usage of the instruction in __flush_cache_user_range to also be covered by our alternative patching efforts. For that we introduce an assembly macro which both deals with alternatives while still tagging the instructions as USER.
