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.

Applied to arm64 (for-next/fixes), thanks!
