locking/refcounts: Do not force refcount_t usage as GPL-only export
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") Cc: stable@vger.kernel.org Signed-off-by: Kees Cook <keescook@chromium.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
