For virtio-net we were getting CPU stall warnings, and fixed it by
calling the scheduler: see f8bb51043945 ("virtio_net: suppress cpu stall
when free_unused_bufs").
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.

All kind of administrative requests should not been retried. Some card
firmware detects this and assumes a replay attack. This patch checks
on failure if the low level functions indicate a retry (EAGAIN) and
checks for the ADMIN flag set on the request message. If this both
are true, the response code for this message is changed to EIO to make
sure the zcrypt API layer does not attempt to retry the request. As of
now the ADMIN flag is set for a request message when
- for EP11 the field 'flags' of the EP11 CPRB struct has the leftmost
bit set.
- for CCA when the CPRB minor version is 'T3', 'T5', 'T6' or 'T7'.
Please note that the do-not-retry only applies to a request
which has been sent to the card (= has been successfully enqueued) but
the reply indicates some kind of failure and by default it would be
replied. It is totally fine to retry a request if a previous attempt
to enqueue the msg into the firmware queue had some kind of failure
and thus the card has never seen this request.

This patch removes most of the debug code which
is build in when CONFIG_ZCRYPT_DEBUG is enabled.
There is no real exploiter for this code any more and
at least one ioctl fails with this code enabled.
The CONFIG_ZCRYPT_DEBUG kernel config option still
makes sense as some debug sysfs entries can get
enabled with this and maybe long term a new better
designed debug and error injection way will get
introduced.
This patch only removes code surrounded by the named
kernel config option. This option should by default
always be off anyway. The structs and defines removed
by the patch have been used only by code surrounded
by a CONFIG_ZCRYPT_DEBUG ifdef and thus can be removed
also.
In the end this patch removes all the failure-injection
possibilities which had been available when the kernel
had been build with CONFIG_ZCRYPT_DEBUG. It has never
been used that much and was too unflexible anyway.

Include linux/io.h instead of asm/io.h everywhere. linux/io.h includes
asm/io.h, so this shouldn't cause any problems. Instead this might help for
some randconfig build errors which were reported due to some undefined io
related functions.
Also move the changed include so it stays grouped together with other
includes from the same directory.
For ctcm_mpc.c also remove not needed comments (actually questions).

Packets bound for peers can queue up prior to the device private key
being set. For example, if persistent keepalive is set, a packet is
queued up to be sent as soon as the device comes up. However, if the
private key hasn't been set yet, the handshake message never sends, and
no timer is armed to retry, since that would be pointless.
But, if a user later sets a private key, the expectation is that those
queued packets, such as a persistent keepalive, are actually sent. So
adjust the configuration logic to account for this edge case, and add a
test case to make sure this works.
Maxim noticed this with a wg-quick(8) config to the tune of:
[Interface]
PostUp = wg set %i private-key somefile
[Peer]
PublicKey = ...
Endpoint = ...
PersistentKeepalive = 25
Here, the private key gets set after the device comes up using a PostUp
script, triggering the bug.

Using `% nr_cpumask_bits` is slow and complicated, and not totally
robust toward dynamic changes to CPU topologies. Rather than storing the
next CPU in the round-robin, just store the last one, and also return
that value. This simplifies the loop drastically into a much more common
pattern.

with the addition of new MAC blocks like CN10K RPM and CN10KB
RPM_USX, LMACs are noncontiguous and CGX blocks are also
noncontiguous. But during RVU driver initialization, the driver
is assuming they are contiguous and trying to access
cgx or lmac with their id which is resulting in kernel panic.

Firmware configures NIX block mapping for all MAC blocks.
The current implementation reads the configuration and
creates the mapping between RVU PF and NIX blocks. But
this configuration is only valid for silicons that support

map to NIX0.

The current design is that, for asynchronous events like link_up and
link_down firmware raises the interrupt to kernel. The previous patch
which added RPM_USX driver has a bug where it uses old csr addresses
for configuring interrupts. Which is resulting in losing interrupts

Pull CXL updates from Dan Williams:
"The highlights in terms of new functionality are support for the
standard CXL Performance Monitor definition that appeared in CXL 3.0,
support for device sanitization (wiping all data from a device),
secure-erase (re-keying encryption of user data), and support for
firmware update. The firmware update support is notable as it reuses
the simple sysfs_upload interface to just cat(1) a blob to a sysfs
file and pipe that to the device.
Additionally there are a substantial number of cleanups and
reorganizations to get ready for RCH error handling (RCH == Restricted
CXL Host == current shipping hardware generation / pre CXL-2.0
topologies) and type-2 (accelerator / vendor specific) devices.
For vendor specific devices they implement a subset of what the
generic type-3 (generic memory expander) driver expects. As a result
the rework decouples optional infrastructure from the core driver
context.
For RCH topologies, where the specification working group did not want
to confuse pre-CXL-aware operating systems, many of the standard
registers are hidden which makes support standard bus features like
AER (PCIe Advanced Error Reporting) difficult. The rework arranges for
the driver to help the PCI-AER core. Bjorn is on board with this
direction but a late regression disocvery means the completion of this
functionality needs to cook a bit longer, so it is code
reorganizations only for now.
Summary:
- Add infrastructure for supporting background commands along with
support for device sanitization and firmware update
- Introduce a CXL performance monitoring unit driver based on the
common definition in the specification.
- Land some preparatory cleanup and refactoring for the anticipated
arrival of CXL type-2 (accelerator devices) and CXL RCH (CXL-v1.1
topology) error handling.
- Rework CPU cache management with respect to region configuration
(device hotplug or other dynamic changes to memory interleaving)
- Fix region reconfiguration vs CXL decoder ordering rules"

We've found that using raid0 with the 'original' layout and discard
enabled with different disk sizes (such that at least two zones are
created) can result in data corruption. This is due to the fact that
the discard handling in 'raid0_handle_discard()' assumes the 'alternate'
layout. We've seen this corruption using ext4 but other filesystems are
likely susceptible as well.
More specifically, while multiple zones are necessary to create the
corruption, the corruption may not occur with multiple zones if they
layout in such a way the layout matches what the 'alternate' layout
would have produced. Thus, not all raid0 devices with the 'original'
layout, different size disks and discard enabled will encounter this
corruption.
The 3.14 kernel inadvertently changed the raid0 disk layout for different
size disks. Thus, running a pre-3.14 kernel and post-3.14 kernel on the
same raid0 array could corrupt data. This lead to the creation of the
'original' layout (to match the pre-3.14 layout) and the 'alternate' layout
(to match the post 3.14 layout) in the 5.4 kernel time frame and an option
to tell the kernel which layout to use (since it couldn't be autodetected).
However, when the 'original' layout was added back to 5.4 discard support
for the 'original' layout was not added leading this issue.
I've been able to reliably reproduce the corruption with the following
test case:
1. create raid0 array with different size disks using original layout
2. mkfs
3. mount -o discard
4. create lots of files
5. remove 1/2 the files
6. fstrim -a (or just the mount point for the raid0 array)
7. umount
8. fsck -fn /dev/md0 (spews all sorts of corruptions)
Let's fix this by adding proper discard support to the 'original' layout.
The fix 'maps' the 'original' layout disks to the order in which they are
read/written such that we can compare the disks in the same way that the
current 'alternate' layout does. A 'disk_shift' field is added to
'struct strip_zone'. This could be computed on the fly in
raid0_handle_discard() but by adding this field, we save some computation
in the discard path.
Note we could also potentially fix this by re-ordering the disks in the
zones that follow the first one, and then always read/writing them using
the 'alternate' layout. However, that is seen as a more substantial change,
and we are attempting the least invasive fix at this time to remedy the
corruption.
I've verified the change using the reproducer mentioned above. Typically,
the corruption is seen after less than 3 iterations, while the patch has
run 500+ iterations.

Sec proxy/message manager data buffer is 60 bytes with the last of the
registers indicating transmission completion. This however poses a bit
of a challenge.
The backing memory for sec_proxy / message manager is regular memory,
and all sec proxy does is to trigger a burst of all 60 bytes of data
over to the target thread backing ring accelerator. It doesn't do a
memory scrub when it moves data out in the burst. When we transmit
multiple messages, remnants of previous message is also transmitted
which results in some random data being set in TISCI fields of
messages that have been expanded forward.
The entire concept of backward compatibility hinges on the fact that
the unused message fields remain 0x0 allowing for 0x0 value to be
specially considered when backward compatibility of message extension
is done.
So, instead of just writing the completion register, we continue
to fill the message buffer up with 0x0 (note: for partial message
involving completion, we already do this).
This allows us to scale and introduce ABI changes back also work with
other boot stages that may have left data in the internal memory.
While at this, be consistent and explicit with the data_reg pointer
increment.

Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Export pcie_retrain_link() for use outside ASPM
- Add Data Link Layer Link Active Reporting as another way for
pcie_retrain_link() to determine the link is up
- Work around link training failures (especially on the ASMedia
ASM2824 switch) by training first at 2.5GT/s and then attempting
higher rates
Resource management:
- When we coalesce host bridge windows, remove invalidated resources
from the resource tree so future allocations work correctly
Hotplug:
- Cancel bringup sequence if card is not present, to keep from
blinking Power Indicator indefinitely
- Reassign bridge resources if necessary for ACPI hotplug
Driver binding:
- Convert platform_device .remove() callbacks to return void instead
of a mostly useless int
Power management:
- Reduce wait time for secondary bus to be ready to speed up resume
- Avoid putting EloPOS E2/S2/H2 (as well as Elo i2) PCIe Ports in
D3cold
- Call _REG when transitioning D-states so AML that uses the PCI
config space OpRegion works, which fixes some ASMedia GPIO
controllers after resume
Virtualization:
- Delay extra 250ms after FLR of Solidigm P44 Pro NVMe to avoid KVM
hang when guest is rebooted
- Add function 1 DMA alias quirk for Marvell 88SE9235

ASPM:
- Disable ASPM on MFD function removal to avoid use-after-free
- Tighten up pci_enable_link_state() and pci_disable_link_state()
interfaces so they don't enable/disable states the driver didn't
specify
- Avoid link retraining race that can happen if ASPM sets link
control parameters while the link is in the midst of training for
some other reason
