Subject: [PATCH] crypto: aesni-intel - fix wrong kfree pointer
kfree(new_key_mem) in rfc4106_set_key() should be called on malloced pointer,
not on aligned one, otherwise it can cause invalid pointer on free.
(Seen at least once when running tcrypt tests with debug kernel.)

Subject: [PATCH] crypto: testmgr - allow aesni-intel and ghash_clmulni-intel
in fips mode
Patch 863b557a88f8c033f7419fabafef4712a5055f85 added NULL entries
for intel accelerated drivers but did not marked these fips allowed.
This cause panic if running tests with fips=1.
For ghash, fips_allowed flag was added in patch
18c0ebd2d8194cce4b3f67e2903fa01bea892cbc.
Without patch, "modprobe tcrypt" fails with
alg: skcipher: Failed to load transform for cbc-aes-aesni: -2
cbc-aes-aesni: cbc(aes) alg self test failed in fips mode!
(panic)
Also add missing cryptd(__driver-cbc-aes-aesni) and
cryptd(__driver-gcm-aes-aesni) test to complement
null tests above, otherwise system complains with
alg: No test for __cbc-aes-aesni (cryptd(__driver-cbc-aes-aesni))
alg: No test for __gcm-aes-aesni (cryptd(__driver-gcm-aes-aesni))
