+Subject: locking/refcounts: Do not force refcount_t usage as GPL-only export
+
+From: Kees Cook <keescook@chromium.org>
+
+commit b562c171cf011d297059bd0265742eb5fab0ad2f upstream.
+
+The refcount_t protection on x86 was not intended to use the stricter
+GPL export. This adjusts the linkage again to avoid a regression in
+the availability of the refcount API.
+
+Reported-by: Dave Airlie <airlied@gmail.com>
+Fixes: 7a46ec0e2f48 ("locking/refcounts, x86/asm: Implement fast refcount overflow protection")
