From: Andrey Konovalov <andreyknvl@xxxxxxxxxx> Subject: kasan, arm64: rename kasan_init_tags and mark as __init Rename kasan_init_tags() to kasan_init_sw_tags() as the upcoming hardware tag-based KASAN mode will have its own initialization routine. Also similarly to kasan_init() mark kasan_init_tags() as __init.
