The patch is fine but the changelog sounds misleading. We don't skip memmove
checking.
If arch don't have memmove than the C implementation from lib/string.c used.
It's instrumented by compile

This patch missed couple call-sites, in kmem_cache_alloc_trace() and
kmem_cache_alloc_node_trace() in include/linux/slab.h,
the return value of kasan_kmalloc() is ignored. Probably worth adding
__must_check to functions like this.
