commit86c83365abupstream. When CONFIG_DEBUG_VIRTUAL is enabled, the default page_to_virt() macro implementation from include/linux/mm.h is used. That definition doesn't account for KASAN tags, which leads to no tags on page_alloc allocations. Provide an arm64-specific definition for page_to_virt() when CONFIG_DEBUG_VIRTUAL is enabled that takes care of KASAN tags.
