Add support for HW QAT Power Management (PM) feature.
This feature is enabled at init time (1) by sending an admin message to
the firmware, targeting the admin AE, that sets the idle time before
the device changes state and (2) by unmasking the PM source of interrupt
in ERRMSK2.
The interrupt handler is extended to handle a PM interrupt which
is triggered by HW when a PM transition occurs. In this case, the
driver responds acknowledging the transaction using the HOST_MSG
mailbox.

There is a regular need in the kernel to provide a way to declare
having a dynamically sized set of trailing elements in a structure.
Kernel code should always use “flexible array members”[1] for these
cases. The older style of one-element or zero-length arrays should
no longer be used[2].
This code was transformed with the help of Coccinelle:
(next-20220214$ spatch --jobs $(getconf _NPROCESSORS_ONLN) --sp-file script.cocci --include-headers --dir . > output.patch)
@@
identifier S, member, array;
type T1, T2;
@@
struct S {
...
T1 member;
T2 array[
- 0
];
};
UAPI and wireless changes were intentionally excluded from this patch
and will be sent out separately.

This is justified because the mask size (eng_grps->engs_num) can be at
most 144 (OTX2_CPT_MAX_ENGINES bits), which is larger than available
storage. 4 * 32 == 128, so this must be 5: 5 * 32bit = 160.
Additionally clear the mask before conversion so trailing bits are zero.

The logic that detects, enables and disables pfvf interrupts was
expecting a single CSR per VF. Instead, the source and mask register are
two registers with a bit per VF.
Due to this, the driver is reading and setting reserved CSRs and not
masking the correct source of interrupts.
Fix the access to the source and mask register for QAT GEN4 devices by
removing the outer loop in adf_gen4_get_vf2pf_sources(),
adf_gen4_enable_vf2pf_interrupts() and
adf_gen4_disable_vf2pf_interrupts() and changing the helper macros
ADF_4XXX_VM2PF_SOU and ADF_4XXX_VM2PF_MSK.

Merge tag 's390-5.17-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 updates from Heiko Carstens:
"Besides all the small improvements and cleanups the most notable part
is the fast vector/SIMD implementation of the ChaCha20 stream cipher,
which is an adaptation of Andy Polyakov's code for the kernel.
Summary:
- add fast vector/SIMD implementation of the ChaCha20 stream cipher,
which mainly adapts Andy Polyakov's code for the kernel
- add status attribute to AP queue device so users can easily figure
out its status
- fix race in page table release code, and and lots of documentation
- remove uevent suppress from cio device driver, since it turned out
that it generated more problems than it solved problems
- quite a lot of virtual vs physical address confusion fixes
- various other small improvements and cleanups all over the place"

The ring reset result values are defined starting from 0x1 instead of 0.
This causes out-of-tree drivers that support this message to understand
that a ring reset failed even if the operation was successful.
Fix by starting the definition of ring reset result values from 0.

The include/linux/crypto.h struct crypto_alg field cra_driver_name description
states "Unique name of the transformation provider. " ... " this contains the
name of the chip or provider and the name of the transformation algorithm."
In case of the stm32-crc driver, field cra_driver_name is identical for all
registered transformation providers and set to the name of the driver itself,
which is incorrect. This patch fixes it by assigning a unique cra_driver_name
to each registered transformation provider.
The kernel crash is triggered when the driver calls crypto_register_shashes()
which calls crypto_register_shash(), which calls crypto_register_alg(), which
calls __crypto_register_alg(), which returns -EEXIST, which is propagated
back through this call chain. Upon -EEXIST from crypto_register_shash(), the
crypto_register_shashes() starts unregistering the providers back, and calls
crypto_unregister_shash(), which calls crypto_unregister_alg(), and this is
where the BUG() triggers due to incorrect cra_refcnt.

platform_get_resource(pdev, IORESOURCE_IRQ, ..) relies on static
allocation of IRQ resources in DT core code, this causes an issue
when using hierarchical interrupt domains using "interrupts" property
in the node as this bypasses the hierarchical setup and messes up the
irq chaining.
In preparation for removal of static setup of IRQ resource from DT core
code use platform_get_irq() so that interrupt mapping is created on demand.
While at it also store the IRQ number in struct cryp_device_data so that
we don't have to call platform_get_irq() frequently.

Add the logic required to enable the compression service for 4xxx devices.
This allows to load the compression firmware image and report
the appropriate compression capabilities.
The firmware image selection for a given device is based on the
'ServicesEnabled' key stored in the internal configuration, which is
added statically at the probe of the device according to the following
rule, by default:
- odd numbered devices assigned to compression services
- even numbered devices assigned to crypto services
In addition, restore the 'ServicesEnabled' key, if present, when SRIOV
is enabled on the device.

Add logic to allow the detection of data compression capabilities for
4xxx devices.
The capability detection logic has been refactored to separate the
crypto capabilities from the compression ones.
This patch is not updating the returned capability mask as, up to now,
4xxx devices are configured only to handle crypto operations.
