  netlink: Move netlink attribute parsing support to lib
  crypto: Fix dead links
  hwrng: timeriomem - New driver
  crypto: chainiv - Use kcrypto_wq instead of keventd_wq
  crypto: cryptd - Per-CPU thread implementation based on kcrypto_wq
  crypto: api - Use dedicated workqueue for crypto subsystem
  crypto: testmgr - Test skciphers with no IVs
  crypto: aead - Avoid infinite loop when nivaead fails selftest
  crypto: skcipher - Avoid infinite loop when cipher fails selftest
  crypto: api - Fix crypto_alloc_tfm/create_create_tfm return convention

Use Intel AES-NI instructions for AES algorithm.
AES cipher algorithms (FIPS-197). AES uses the Rijndael
algorithm.
Rijndael appears to be consistently a very good performer in
both hardware and software across a wide range of computing
environments regardless of its use in feedback or non-feedback
modes. Its key setup time is excellent, and its key agility is
good. Rijndael's very low memory requirements make it very well
suited for restricted-space environments, in which it also
demonstrates excellent performance. Rijndael's operations are
among the easiest to defend against power and timing attacks.
The AES specifies three key sizes: 128, 192 and 256 bits

This driver provides kernel-side support for a generic Random
Number Generator used by reading a 'dumb' iomem address that
is to be read no faster than, for example, once a second;
the default FPGA bitstream on the TS-7800 has such functionality.
