Remove the legacy device driver code for CEX2 and CEX3 cards.
The last machines which are able to handle CEX2 crypto cards
are z10 EC first available 2008 and z10 BC first available 2009.
The last machines able to handle a CEX3 crypto card are
z196 first available 2010 and z114 first available 2011.
Please note that this does not imply to drop CEX2 and CEX3
support in general. With older kernels on hardware up to the
aforementioned machine models these crypto cards will get
support by IBM.
The removal of the CEX2 and CEX3 device drivers code opens up
some simplifications, for example support for crypto cards
without rng support can be removed also.

This driver is similar so theoretically the same logic applies.

Remove ZCRYPT_MULTIDEVNODES kernel config option and make
the dependent code always build.
The last years showed, that this option is enabled on all distros
and exploited by some features (for example CEX plugin for kubernetes).
So remove this choice as it was never used to switch off the multiple
devices support for the zcrypt device driver.

For historical reasons, unbound workqueues with max concurrency limit of 1
are considered ordered, even though the concurrency limit hasn't been
system-wide for a long time. This creates ambiguity around whether ordered
execution is actually required for correctness, which was actually confusing
for e.g. btrfs (btrfs updates are being routed through the btrfs tree).
There aren't that many users in the tree which use the combination and there
are pending improvements to unbound workqueue affinity handling which will
make inadvertent use of ordered workqueue a bigger loss. This pull request
clarifies the situation for most of them by updating the ones which require
ordered execution to use alloc_ordered_workqueue().
There are some conversions being routed through subsystem-specific trees and
likely a few stragglers. Once they're all converted, workqueue can trigger a
warning on unbound + @max_active==1 usages and eventually drop the implicit
ordered behavior.

TRNG "sample size" (the total number of entropy samples that will be taken
during entropy generation) default / POR value is very conservatively
set to 2500.
Let's set it to 512, the same as the caam driver in U-boot
(drivers/crypto/fsl_caam.c) does.
This solves the issue of RNG performance dropping after a suspend/resume
cycle on parts where caam loses power, since the initial U-boot setttings
are lost and kernel does not restore them when resuming.
Note: when changing the sample size, the self-test parameters need to be
updated accordingly.

A QAT GEN4 device can be currently configured for crypto (sym;asym) or
compression (dc).
This patch extends the configuration to support more variations of these
services, download the correct FW images on the device and report the
correct capabilities on the device based on the configured service.
The device can now be configured with the following services:
"sym", "asym", "dc", "sym;asym", "asym;sym", "sym;dc", "dc;sym",
"asym;dc", "dc;asym".
With this change, the configuration "sym", "asym", "sym;dc", "dc;sym",
"asym;dc", "dc;asym" will be accessible only via userspace, i.e. the driver
for those configurations will not register into the crypto framework.
Support for such configurations in kernel will be enabled in a later
patch.
The pairs "sym;asym" and "asym;sym" result in identical device config.
As do "sym;dc", "dc;sym", and "asym;dc", "dc;asym".

The data structure adf_fw_config is used to select which firmware image
is loaded on a certain set of accelerator engines.
When support for 402xx was added, the adf_fw_config arrays were
duplicated in order to select different firmware images.
Since the configurations are the same regardless of the QAT GEN4
flavour, in preparation for adding support for multiple configurations,
refactor the logic that retrieves the firmware names in the 4xxx driver.
The structure adf_fw_config has been changed to contain a firmware object
id that is then mapped to a firmware name depending of the device type.

Move initialization of debugfs entries to a separate file.
This simplifies the exclusion of the debugfs logic in the QAT driver
when the kernel is built with CONFIG_DEBUG_FS=n.
In addition, it will allow to consolidate the addition of debugfs
entries to a single location in the code.
This implementation adds infrastructure to create (and remove) debugfs
entries at two different stages. The first, done when a device is probed,
allows to keep debugfs entries persistent between a transition in device
state (up to down or vice versa). The second, done after the initialization
phase, allows to have debugfs entries that are accessible only when
the device is up.
In addition, move the creation of debugfs entries for configuration
to the newly created function adf_dbgfs_init() and replace symbolic
permissions with octal permissions when creating the debugfs files.
This is to resolve the following warning reported by checkpatch:
WARNING: Symbolic permissions 'S_IRUSR' are not preferred. Consider using octal permissions '0400'.

The value returned by an fsl-mc driver's remove function is mostly
ignored. (Only an error message is printed if the value is non-zero
and then device removal continues unconditionally.)
So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

not fallback to software implementation for this packet size. Otherwise
there is a strange bump up in crypto performance at 256 byte packet size.

BACKGROUND
==========
When multiple work items are queued to a workqueue, their execution order
doesn't match the queueing order. They may get executed in any order and
simultaneously. When fully serialized execution - one by one in the queueing
order - is needed, an ordered workqueue should be used which can be created
with alloc_ordered_workqueue().
However, alloc_ordered_workqueue() was a later addition. Before it, an
ordered workqueue could be obtained by creating an UNBOUND workqueue with
@max_active==1. This originally was an implementation side-effect which was
broken by 4c16bd327c ("workqueue: restore WQ_UNBOUND/max_active==1 to be
ordered"). Because there were users that depended on the ordered execution,
5c0338c687 ("workqueue: restore WQ_UNBOUND/max_active==1 to be ordered")
made workqueue allocation path to implicitly promote UNBOUND workqueues w/
@max_active==1 to ordered workqueues.
While this has worked okay, overloading the UNBOUND allocation interface
this way creates other issues. It's difficult to tell whether a given
workqueue actually needs to be ordered and users that legitimately want a
min concurrency level wq unexpectedly gets an ordered one instead. With
planned UNBOUND workqueue updates to improve execution locality and more
prevalence of chiplet designs which can benefit from such improvements, this
isn't a state we wanna be in forever.
This patch series audits all callsites that create an UNBOUND workqueue w/
@max_active==1 and converts them to alloc_ordered_workqueue() as necessary.
WHAT TO LOOK FOR
================
The conversions are from
alloc_workqueue(WQ_UNBOUND | flags, 1, args..)
to
alloc_ordered_workqueue(flags, args...)
which don't cause any functional changes. If you know that fully ordered
execution is not ncessary, please let me know. I'll drop the conversion and
instead add a comment noting the fact to reduce confusion while conversion
is in progress.
If you aren't fully sure, it's completely fine to let the conversion
through. The behavior will stay exactly the same and we can always
reconsider later.
As there are follow-up workqueue core changes, I'd really appreciate if the
patch can be routed through the workqueue tree w/ your acks. Thanks.

On OcteonTX2/OctoenTX3 variants of silicon, Admin function (AF)
handles resource allocation and configuration for PFs and their VFs.
PFs request the AF directly, via mailboxes.
Unlike PFs, VFs cannot send a mailbox request directly. A VF sends
mailbox messages to its parent PF, with which it shares a
mailbox region. The PF then forwards these messages to the AF.
This patch adds code to configure inline-IPsec HW resources for
CPT VFs as CPT VFs cannot send a mailbox request directly to AF.

This patch adds support for AF -> CPT PF uplink mailbox messages
and adds a mailbox handler to submit a CPT instruction from AF as
current architecture doesn't allow AF to submit CPT instruction
directly to HW.

Move to drivers/char/hw_random since histb-(t)rng does not provide
cryptography pseudo rng.
histb-rng is pretty like hisi-rng, but after investigation, we confirm
there is no RNG_PHY_SEED register on histb-rng so a separate driver is
needed.
Still we rename relevant function names to match those in hisi-rng.

Smatch complains that "dma" is uninitialized if dma_pool_alloc() fails.
This is true, but also harmless. Anyway, move the assignment after the
error checking to silence this warning.

RNG (re-)initialization will be needed on pm resume path,
thus refactor the corresponding code out of the probe callback.
