+Subject: [PATCH] drivers/crypto/nx: fix init race, alignmasks and GCM bug
+
+ Fixes a race on driver init with registering algorithms where the
+driver status flag wasn't being set before self testing started.
+
+ Added the cra_alignmask field for CBC and ECB modes.
+
+ Fixed a bug in GCM where AES block size was being used instead of
+authsize.
