[Subtree] Removing import-layers directory
As part of the move to subtrees, need to bring all the import layers content to the top level. Change-Id: I4a163d10898cbc6e11c27f776f60e1a470049d8f Signed-off-by: Dave Cobbley <david.j.cobbley@linux.intel.com> Signed-off-by: Brad Bishop <bradleyb@fuzziesquirrel.com>

+Subject: [PATCH] Throw exception when IV is used with ECB or CTR
+
+The IV parameter is currently ignored when initializing
+a cipher in ECB or CTR mode.
+
+For CTR mode, it is confusing: it takes some time to see
+that a different parameter is needed (the counter).
+
+For ECB mode, it is outright dangerous.
+
+This patch forces an exception to be raised.
+
+Upstream-Status: Backport
