Alex Sverdlin 5f11e22d1d ARM: 9242/1: kasan: Only map modules if CONFIG_KASAN_VMALLOC=n 
[ Upstream commit 823f606ab6 ]

In case CONFIG_KASAN_VMALLOC=y kasan_populate_vmalloc() allocates the
shadow pages dynamically. But even worse is that kasan_release_vmalloc()
releases them, which is not compatible with create_mapping() of
MODULES_VADDR..MODULES_END range:
