Move 'ecc_get_curve' to 'include/crypto/ecc_curve.h', so everyone
in kernel tree can easily get ecc curve params;

1. crypto and crypto/atmel-ecc:
Move curve id of ECDH from the key into the algorithm name instead
in crypto and atmel-ecc, so ECDH algorithm name change form 'ecdh'
to 'ecdh-nist-pxxx', and we cannot use 'curve_id' in 'struct ecdh';
2. crypto/testmgr and net/bluetooth:
Modify 'testmgr.c', 'testmgr.h' and 'net/bluetooth' to adapt
the modification.

Given that crypto_alloc_tfm() may return ERR pointers, and to avoid
crashes on obscure error paths where such pointers are presented to
crypto_destroy_tfm() (such as [0]), add an ERR_PTR check there
before dereferencing the second argument as a struct crypto_tfm
pointer.

Pull char/misc driver updates from Greg KH:
"Here is the large set of char/misc/whatever driver subsystem updates
for 5.12-rc1. Over time it seems like this tree is collecting more and
more tiny driver subsystems in one place, making it easier for those
maintainers, which is why this is getting larger.
Included in here are:
- coresight driver updates
- habannalabs driver updates
- virtual acrn driver addition (proper acks from the x86 maintainers)
- broadcom misc driver addition
- speakup driver updates
- soundwire driver updates
- fpga driver updates
- amba driver updates
- mei driver updates
- vfio driver updates
- greybus driver updates
- nvmeem driver updates
- phy driver updates
- mhi driver updates
- interconnect driver udpates
- fsl-mc bus driver updates
- random driver fix
- some small misc driver updates (rtsx, pvpanic, etc.)
All of these have been in linux-next for a while, with the only
reported issue being a merge conflict due to the dfl_device_id
addition from the fpga subsystem in here"

Pull keyring updates from David Howells:
"Here's a set of minor keyrings fixes/cleanups that I've collected from
various people for the upcoming merge window.
A couple of them might, in theory, be visible to userspace:
- Make blacklist_vet_description() reject uppercase letters as they
don't match the all-lowercase hex string generated for a blacklist
search.
This may want reconsideration in the future, but, currently, you
can't add to the blacklist keyring from userspace and the only
source of blacklist keys generates lowercase descriptions.
- Fix blacklist_init() to use a new KEY_ALLOC_* flag to indicate that
it wants KEY_FLAG_KEEP to be set rather than passing KEY_FLAG_KEEP
into keyring_alloc() as KEY_FLAG_KEEP isn't a valid alloc flag.
This isn't currently a problem as the blacklist keyring isn't
currently writable by userspace.
The rest of the patches are cleanups and I don't think they should
have any visible effect"

The length ('len' parameter) passed to crypto_ecdh_decode_key() is never
checked against the length encoded in the passed buffer ('buf'
parameter). This could lead to an out-of-bounds access when the passed
length is less than the encoded length.
Add a check to prevent that.

It is not trivial to trace back why exactly the tnepres variant of
serpent was added ~17 years ago - Google searches come up mostly empty,
but it seems to be related with the 'kerneli' version, which was based
on an incorrect interpretation of the serpent spec.
In other words, nobody is likely to care anymore today, so let's get rid
of it.

The Michael MIC driver uses the cra_alignmask to ensure that pointers
presented to its update and finup/final methods are 32-bit aligned.
However, due to the way the shash API works, this is no guarantee that
the 32-bit reads occurring in the update method are also aligned, as the
size of the buffer presented to update may be of uneven length. For
instance, an update() of 3 bytes followed by a misaligned update() of 4
or more bytes will result in a misaligned access using an accessor that
is not suitable for this.
On most architectures, this does not matter, and so setting the
cra_alignmask is pointless. On architectures where this does matter,
setting the cra_alignmask does not actually solve the problem.
So let's get rid of the cra_alignmask, and use unaligned accessors
instead, where appropriate.

The AES-NI driver implements XTS via the glue helper, which consumes
a struct with sets of function pointers which are invoked on chunks
of input data of the appropriate size, as annotated in the struct.
Let's get rid of this indirection, so that we can perform direct calls
to the assembler helpers. Instead, let's adopt the arm64 strategy, i.e.,
provide a helper which can consume inputs of any size, provided that the
penultimate, full block is passed via the last call if ciphertext stealing
needs to be applied.
This also allows us to enable the XTS mode for i386.

Sync the BLAKE2b code with the BLAKE2s code as much as possible:
- Move a lot of code into new headers <crypto/blake2b.h> and
<crypto/internal/blake2b.h>, and adjust it to be like the
corresponding BLAKE2s code, i.e. like <crypto/blake2s.h> and
<crypto/internal/blake2s.h>.
- Rename constants, e.g. BLAKE2B_*_DIGEST_SIZE => BLAKE2B_*_HASH_SIZE.
- Use a macro BLAKE2B_ALG() to define the shash_alg structs.
- Export blake2b_compress_generic() for use as a fallback.
This makes it much easier to add optimized implementations of BLAKE2b,
as optimized implementations can use the helper functions
crypto_blake2b_{setkey,init,update,final}() and
blake2b_compress_generic(). The ARM implementation will use these.
But this change is also helpful because it eliminates unnecessary
differences between the BLAKE2b and BLAKE2s code, so that the same
improvements can easily be made to both. (The two algorithms are
basically identical, except for the word size and constants.) It also
makes it straightforward to add a library API for BLAKE2b in the future
if/when it's needed.
This change does make the BLAKE2b code slightly more complicated than it
needs to be, as it doesn't actually provide a library API yet. For
example, __blake2b_update() doesn't really need to exist yet; it could
just be inlined into crypto_blake2b_update(). But I believe this is
outweighed by the benefits of keeping the code in sync.
