8e7d7ce2e3 crypto: x86/aria - add keystream array into request ctx
avx accelerated aria module used local keystream array.
But, keystream array size is too big.
So, it puts the keystream array into request ctx.

91dfd98216 crypto: ccp - Avoid page allocation failure warning for SEV_GET_ID2
For SEV_GET_ID2, the user provided length does not have a specified
limitation because the length of the ID may change in the future.  The
kernel memory allocation, however, is implicitly limited to 4MB on x86 by
the page allocator, otherwise the kzalloc() will fail.

When this happens, it is best not to spam the kernel log with the warning.
Simply fail the allocation and return ENOMEM to the user.

====================
devlink: code split and structured instance walk

Split devlink.c into a handful of files, trying to keep the "core"
code away from all the command-specific implementations.
The core code has been quite scattered until now. Going forward we can
consider using a source file per-subobject, I think that it's quite
beneficial to newcomers (based on relative ease with which folks
contribute to ethtool vs devlink). But this series doesn't split
everything out, yet - partially due to backporting concerns,
but mostly due to lack of time. Bulk of the netlink command
handling is left in a leftover.c file.

Introduce a context structure for dumps, and use it to store
the devlink instance ID of the last dumped devlink instance.
This means we don't have to restart the walk from 0 each time.

Finally - introduce a "structured walk". A centralized dump handler
in devlink/netlink.c which walks the devlink instances, deals with
refcounting/locking, simplifying the per-object implementations quite
a bit. Inspired by the ethtool code.

5ce76d78b9 devlink: convert remaining dumps to the by-instance scheme
Soon we'll have to check if a devlink instance is alive after
locking it. Convert to the by-instance dumping scheme to make
refactoring easier.

Most of the subobject code no longer has to worry about any devlink
locking / lifetime rules (the only ones that still do are the two subject
types which stubbornly use their own locking). Both dump and do callbacks
are given a devlink instance which is already locked and good-to-access
(do from the .pre_doit handler, dump from the new dump indirection).

Note that we'll now check presence of an op (e.g. for sb_pool_get)
under the devlink instance lock, that will soon be necessary anyway,
because we don't hold refs on the driver modules so the memory
in which ops live may be gone for a dead instance, after upcoming
locking changes.

0da6855378 Merge branch 'net-ipa-simplify-ipa-interrupt-handling'
Alex Elder says:

====================
net: ipa: simplify IPA interrupt handling

One of the IPA's two IRQs fires when data on a suspended channel is
available (to request that the channel--or system--be resumed to
recieve the pending data).  This interrupt also handles a few
conditions signaled by the embedded microcontroller.

For this "IPA interrupt", the current code requires a handler to be
dynamically registered for each interrupt condition.  Any condition
that has no registered handler is quietly ignored.  This design is
derived from the downstream IPA driver implementation.

There isn't any need for this complexity.  Even in the downstream
code, only four of the available 30 or so IPA interrupt conditions
are ever handled.  So these handlers can pretty easily just be
called directly in the main IRQ handler function.

This series simplifies the interrupt handling code by having the
small number of IPA interrupt handlers be called directly, rather
than having them be registered dynamically.

Version 2 just adds a missing forward-reference, as suggested by
Caleb.

bfb798545d net: ipa: don't maintain IPA interrupt handler array
We can call the two IPA interrupt handler functions directly;
there's no need to maintain the array of handler function pointers
any more.

8d8d3f1a3e net: ipa: kill ipa_interrupt_add()
The dynamic assignment of IPA interrupt handlers isn't needed; we
only handle three IPA interrupt types, and their handler functions
are now assigned directly.  We can get rid of ipa_interrupt_add()
and ipa_interrupt_remove() now, because they serve no purpose.

482ae3a993 net: ipa: register IPA interrupt handlers directly
Declare the microcontroller IPA interrupt handler publicly, and
assign it directly in ipa_interrupt_config().  Make the SUSPEND IPA
interrupt handler public, and rename it ipa_power_suspend_handler().
Assign it directly in ipa_interrupt_config() as well.

This makes it unnecessary to do this in ipa_interrupt_add().  Make
similar changes for removing IPA interrupt handlers.

The next two patches will finish the cleanup, removing the
add/remove functions and the handler array entirely.

d50ed35587 net: ipa: enable IPA interrupt handlers separate from registration
Expose ipa_interrupt_enable() and have functions that register
IPA interrupt handlers enable them directly, rather than having the
registration process do that.  Do the same for disabling IPA
interrupt handlers.

8e461e1f09 net: ipa: introduce ipa_interrupt_enable()
Create new function ipa_interrupt_enable() to encapsulate enabling
one of the IPA interrupt types.  Introduce ipa_interrupt_disable()
to reverse that operation.  Add a helper function to factor out the
common register update used by both.

Use these in ipa_interrupt_add() and ipa_interrupt_remove().

e5709b7c1e net: ipa: introduce a common microcontroller interrupt handler
The prototype for an IPA interrupt handler supplies the IPA
interrupt ID, so it's possible to use a single function to handle
any type of microcontroller interrupt.

Introduce ipa_uc_interrupt_handler(), which calls the event or the
response handler depending on the IRQ ID provided.  Register the new
function as the handler for both microcontroller IPA interrupt types.

The called functions don't use their "irq_id" arguments, so remove
them.

Lorenzo Bianconi says:

====================
enetc: unlock XDP_REDIRECT for XDP non-linear buffers

Unlock XDP_REDIRECT for S/G XDP buffer and rely on XDP stack to properly
take care of the frames.
Rely on XDP_FLAGS_HAS_FRAGS flag to check if it really necessary to access
non-linear part of the xdp_buff/xdp_frame.

enetc_map_rx_buff_to_xdp() to enetc_add_rx_buff_to_xdp() and do not always
access skb_shared_info in the xdp_buff/xdp_frame since it is located in a
different cacheline with respect to hard_start and data xdp pointers.

In current driver, MAC will always enable 2ns delay in RGMII mode,

957445d730 platform/chrome: cros_ec: Shutdown on EC Panic
When an EC panic is reported, attempt an orderly shutdown.
Force a shutdown after a brief timeout if the orderly shutdown
fails for any reason.

Using the common hw_protection_shutdown utility function since
an EC panic has the potential to cause hw damage.

This is all best effort. EC should also force a hard reset after a
short timeout.
