crypto: arm64/ghash - drop PMULL based shash
There are two ways to implement SIMD accelerated GCM on arm64:
- using the PMULL instructions for carryless 64x64->128 multiplication,
in which case the architecture guarantees that the AES instructions are
available as well, and so we can use the AEAD implementation that combines
both,
- using the PMULL instructions for carryless 8x8->16 bit multiplication,
which is implemented as a shash, and can be combined with any ctr(aes)
implementation by the generic GCM AEAD template driver.
So let's drop the 64x64->128 shash driver, which is never needed for GCM,
and not suitable for use anywhere else.

crypto: ccp - Fix use of merged scatterlists
Running the crypto manager self tests with
CONFIG_CRYPTO_MANAGER_EXTRA_TESTS may result in several types of errors
when using the ccp-crypto driver:
alg: skcipher: cbc-des3-ccp encryption failed on test vector 0; expected_error=0, actual_error=-5 ...
alg: skcipher: ctr-aes-ccp decryption overran dst buffer on test vector 0 ...
alg: ahash: sha224-ccp test failed (wrong result) on test vector ...
These errors are the result of improper processing of scatterlists mapped
for DMA.
Given a scatterlist in which entries are merged as part of mapping the
scatterlist for DMA, the DMA length of a merged entry will reflect the
combined length of the entries that were merged. The subsequent
scatterlist entry will contain DMA information for the scatterlist entry
after the last merged entry, but the non-DMA information will be that of
the first merged entry.
The ccp driver does not take this scatterlist merging into account. To
address this, add a second scatterlist pointer to track the current
position in the DMA mapped representation of the scatterlist. Both the DMA
representation and the original representation of the scatterlist must be
tracked as while most of the driver can use just the DMA representation,
scatterlist_map_and_copy() must use the original representation and
expects the scatterlist pointer to be accurate to the original
representation.
In order to properly walk the original scatterlist, the scatterlist must
be walked until the combined lengths of the entries seen is equal to the
DMA length of the current entry being processed in the DMA mapped
representation.

crc-t10dif: use fallback in initial state
Currently the crc-t10dif module starts out with the fallback disabled
and crct10dif_tfm == NULL. crc_t10dif_mod_init() tries to allocate
crct10dif_tfm, and if it fails it enables the fallback.
This is backwards because it means that any call to crc_t10dif() prior
to module_init (which could theoretically happen from built-in code)
will crash rather than use the fallback as expected. Also, it means
that if the initial tfm allocation fails, then the fallback stays
permanently enabled even if a crct10dif implementation is loaded later.
Change it to use the more logical solution of starting with the fallback
enabled, and disabling the fallback when a tfm gets allocated for the
first time. This change also ends up simplifying the code.
Also take the opportunity to convert the code to use the new static_key
API, which is much less confusing than the old and deprecated one.

padata: upgrade smp_mb__after_atomic to smp_mb in padata_do_serial
A 5.7 kernel hangs during a tcrypt test of padata that waits for an AEAD
request to finish. This is only seen on large machines running many
concurrent requests.
The issue is that padata never serializes the request. The removal of
the reorder_objects atomic missed that the memory barrier in
padata_do_serial() depends on it.
Upgrade the barrier from smp_mb__after_atomic to smp_mb to get correct
ordering again.

The locking in af_alg_release_parent is broken as the BH socket
lock can only be taken if there is a code-path to handle the case
where the lock is owned by process-context. Instead of adding
such handling, we can fix this by changing the ref counts to
atomic_t.

ref count when a socket changes from nokey to normal.

crypto: algboss - don't wait during notifier callback
When a crypto template needs to be instantiated, CRYPTO_MSG_ALG_REQUEST
is sent to crypto_chain. cryptomgr_schedule_probe() handles this by
starting a thread to instantiate the template, then waiting for this
thread to complete via crypto_larval::completion.
This can deadlock because instantiating the template may require loading
modules, and this (apparently depending on userspace) may need to wait
for the crc-t10dif module (lib/crc-t10dif.c) to be loaded. But
crc-t10dif's module_init function uses crypto_register_notifier() and
therefore takes crypto_chain.rwsem for write. That can't proceed until
the notifier callback has finished, as it holds this semaphore for read.
Fix this by removing the wait on crypto_larval::completion from within
cryptomgr_schedule_probe(). It's actually unnecessary because
crypto_alg_mod_lookup() calls crypto_larval_wait() itself after sending
CRYPTO_MSG_ALG_REQUEST.
This only actually became a problem in v4.20 due to commit b76377543b73
("crc-t10dif: Pick better transform if one becomes available"), but the
unnecessary wait was much older.

This patch reverts the main part of switching direct io implementation
to iomap infrastructure. There's a problem in invalidate page that
couldn't be solved as regression in this development cycle.
The problem occurs when buffered and direct io are mixed, and the ranges
overlap. Although this is not recommended, filesystems implement
measures or fallbacks to make it somehow work. In this case, fallback to
buffered IO would be an option for btrfs (this already happens when
direct io is done on compressed data), but the change would be needed in
the iomap code, bringing new semantics to other filesystems.
Another problem arises when again the buffered and direct ios are mixed,
invalidation fails, then -EIO is set on the mapping and fsync will fail,
though there's no real error.
There have been discussions how to fix that, but revert seems to be the
least intrusive option.
net: ethernet: ti: ale: fix allmulti for nu type ale
On AM65xx MCU CPSW2G NUSS and 66AK2E/L NUSS allmulti setting does not allow

This happens, because ALE VLAN entries on these SoCs do not contain port
masks for reg/unreg mcast packets, but instead store indexes of
ALE_VLAN_MASK_MUXx_REG registers which intended for store port masks for
reg/unreg mcast packets.
This path was missed by commit 9d1f6447274f ("net: ethernet: ti: ale: fix
seeing unreg mcast packets with promisc and allmulti disabled").
Hence, fix it by taking into account ALE type in cpsw_ale_set_allmulti().
