Subject[PATCH 2/2 v2] crypto: skip algs not flagged fips_allowed in fips mode
From
Date
Because all fips-allowed algorithms must be self-tested before they
can be used, they will all have entries in testmgr.c's alg_test_descs[].
Skip self-tests for any algs not flagged as fips_approved and return
-EINVAL when in fips mode.

Resending with properly updated patch v2 tag.
