Hi Linus:
This push fixes the following issues:
- Fix pointer size when caam is used with AArch64 boot loader on
AArch32 kernel.
- Fix ahash state corruption in marvell driver.
- Fix buggy algif_aed tag handling.
- Prevent mcryptd from being used with incompatible algorithms
which can cause c

In the 4.9 kernel, virtually-mapped stacks will be supported and enabled by
default on x86_64. This has been exposing a number of problems in which
on-stack buffers are being passed into the crypto API, which to support crypto
accelerators operates on 'struct page' rather than on virtual memory.
Hi Gonglei.

SipHash is a 64-bit keyed hash function that is actually a
cryptographically secure PRF, like HMAC. Except SipHash is super fast,
and is meant to be used as a hashtable keyed lookup function.
SipHash isn't just some new trendy hash function. It's been around for a
while, and there really isn't any

This converts the ChaCha20 code from a blkcipher to a skcipher, which
is now the preferred way to implement symmetric block and stream ciphers.
This ports the generic and x86 versions at the same time because the
latter reuses routines of the former.
Note that the skcipher_walk() API guarantees t

The bit-sliced NEON implementation of AES only performs optimally if
it can process 8 blocks of input in parallel. This is due to the nature
of bit slicing, where the n-th bit of each byte of AES state of each input

Hi Herbert,
The scatterwalk_map_and_copy function copies ordinary buffers to and
from scatterlists. These buffers can, of course, be on the stack, and
this remains the most popular use of this function -- getting info
between stack buffers and DMA regions. It's mostly used for adding or
