Add an AEAD template that does hash-then-cipher (unlike authenc that does
cipher-then-hash). This is required for a number of Kerberos 5 encoding
types.
[!] Note that the net/sunrpc/auth_gss/ implementation gets a pair of
ciphers, one non-CTS and one CTS, using the former to do all the aligned
blocks and the latter to do the last two blocks if they aren't also
aligned. It may be necessary to do this here too for performance reasons -
but there are considerations both ways:
(1) firstly, there is an optimised assembly version of cts(cbc(aes)) on
x86_64 that should be used instead of having two ciphers;
(2) secondly, none of the hardware offload drivers seem to offer CTS
support (Intel QAT does not, for instance).
However, I don't know if it's possible to query the crypto API to find out
whether there's an optimised CTS algorithm available.

Right now vop2_cluster_init() copies the base vop2_cluster_regs
and adapts the reg value with the current window's offset before
adding the fields to the regmap.
This conflicts with the notion of reg_fields being const, see
https://lore.kernel.org/all/20240706-regmap-const-structs-v1-1-d08c776da787@weissschuh.net/
for reference, which now causes checkpatch to actually warn about that.
So instead of creating one big copy and changing it afterwards,
add the reg_fields individually using devm_regmap_field_alloc().
Functional it is the same, just that the reg_field we're handling
can stay const.

below:
1> Query 'power1_alarm' attribute when the power capping occurs.
2> Query 'power1_alarm' attribute when the power capping is over
and the current average power is less then power cap value.
The root cause is that the resource->power_alarm is set to true
at the first step. And power meter use this old value to show
the power alarm state instead of the current the comparison value.

The BPF sideband information is tracked using a separate thread and
evlist. But it's only useful for profiling kernel and we can skip it
when users profile their application only.
It seems it already fails to open the sideband event in that case.
Let's remove the noise in the verbose output anyway.

Define debugfs attributes used to access status registers in a data
structure and loop through it instead of creating debugfs files
one by one. This reduces code size and simplifies adding additional
attributes if needed.

Define debugfs attributes which need block data access in a data
structure and loop through it instead of creating debugfs files
one by one. This reduces code size and simplifies adding additional
attributes if needed.
While this is currently only used for manufacturer specific attributes,
the access code is generic and also works for other block attributes,
so rename operation functions from _mfg to _block.
While at it, rename the "revison" file to "pmbus_revision" to make its
meaning more obvious and to create a clear distinction against the
"mfg_revision" file.

The regulator notification function never returns an error.

Drop contitionals around debugfs code to compile it unconditionally.
In practice it will be optimized away by the compiler if CONFIG_DEBUG_FS
is not enabled, so the code size is not affected by this change.
Also silently ignore errors if debugfs initialization fails.

The I2C core now manages a debugfs directory per I2C client. PMBus has
its own debugfs hierarchy. Link the two, so a user will be pointed to
the I2C domain from the PMBus domain.
