Andrey Konovalov d73665b4a9 arm64: kasan: fix page_alloc tagging with DEBUG_VIRTUAL 
commit 86c83365ab76e4b43cedd3ce07a07d32a4dc79ba upstream.

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.

Fixes: 2813b9c029 ("kasan, mm, arm64: tag non slab memory allocated via pagealloc")
