[ Upstream commit 55bd9ac468397c4f12a33b7ec714b5d0362c3aa2 ]
IS_ENABLED() matches names exactly, so the missing "CONFIG_" prefix
means this code would never be built.
Also fixes a missing newline in pr_warn().
Fixes: 970d54f99cea ("powerpc/book3s64/hash: Disable 16M linear mapping size if not aligned")
