6.5-stable review patch. If anyone has any objections, please let me know.
------------------
From: Herbert Xu herbert@gondor.apana.org.au
[ Upstream commit 04a93202ed7c3b451bf22d3ff4bcd379df27f299 ]
The modular build fails because the self-test code depends on pkcs7 which in turn depends on x509 which contains the self-test.
Split the self-test out into its own module to break the cycle.
