Spammy devices can flood kernel logs with AER errors and slow/stall
execution. Add per-device ratelimits for AER correctable and non-fatal
uncorrectable errors that use the kernel defaults (10 per 5s). Logging of
fatal errors is not ratelimited.
There are two AER logging entry points:
- aer_print_error() is used by DPC and native AER
- pci_print_aer() is used by GHES and CXL
The native AER aer_print_error() case includes a loop that may log details
from multiple devices, which are ratelimited individually. If we log
details for any device, we also log the Error Source ID from the Root Port
or RCEC.
If no such device details are found, we still log the Error Source from the
ERR_* Message, ratelimited by the Root Port or RCEC that received it.
The DPC aer_print_error() case is not ratelimited, since this only happens
for fatal errors.
The CXL pci_print_aer() case is ratelimited by the Error Source device.
The GHES pci_print_aer() case is via aer_recover_work_func(), which
searches for the Error Source device. If the device is not found, there's
no per-device ratelimit, so we use a system-wide ratelimit that covers all
error types (correctable, non-fatal, and fatal).
Sargun at Meta reported internally that a flood of AER errors causes RCU
CPU stall warnings and CSD-lock warnings.
Tested using aer-inject[1]. Sent 11 AER errors. Observed 10 errors logged
while AER stats (cat /sys/bus/pci/devices/<dev>/aer_dev_correctable) show
true count of 11.

Previously aer_get_device_error_info() and aer_print_error() took a pointer
to struct aer_err_info and a pointer to a pci_dev. Typically the pci_dev
was one of the elements of the aer_err_info.dev[] array (DPC was an
exception, where the dev[] array was unused).
Convert aer_get_device_error_info() and aer_print_error() to take an index
into the aer_err_info.dev[] array instead. A future patch will add
per-device ratelimit information, so the index makes it convenient to find
the ratelimit associated with the device.
To accommodate DPC, set info->dev[0] to the DPC port before using these
interfaces.

aer_print_error() produces output at a printk level (KERN_ERR/KERN_WARNING/
etc) that depends on the kind of error, and it calls pcie_print_tlp_log(),
which previously always produced output at KERN_ERR.
Add a "level" parameter so aer_print_error() can control the level of the
pcie_print_tlp_log() output to match.

There are two AER logging entry points:
- aer_print_error() is used by DPC (dpc_process_error()) and native AER
handling (aer_process_err_devices()).
- pci_print_aer() is used by GHES (aer_recover_work_func()) and CXL
(cxl_handle_rdport_errors())
Both use __aer_print_error() to print the AER error bits. Previously
__aer_print_error() also incremented the AER statistics via
pci_dev_aer_stats_incr().
Call pci_dev_aer_stats_incr() early in the entry points instead of in
__aer_print_error() so we update the statistics even if the actual printing
of error bits is rate limited by a future change.

Previously we decoded the AER Error Source ID in aer_isr_one_error_type(),
then again in find_source_device() if we didn't find any devices with
errors logged in their AER Capabilities.
Consolidate this so we only decode and log the Error Source ID once in
aer_isr_one_error_type(). Add a "found" parameter so we can add a note
when we didn't find any downstream devices with errors logged in their AER
Capability.
This changes the dmesg logging when we found no devices with errors logged:

DPC Error Source ID is only valid when the DPC Trigger Reason indicates
that DPC was triggered due to reception of an ERR_NONFATAL or ERR_FATAL
Message (PCIe r6.0, sec 7.9.14.5).
When DPC was triggered by ERR_NONFATAL (PCI_EXP_DPC_STATUS_TRIGGER_RSN_NFE)
or ERR_FATAL (PCI_EXP_DPC_STATUS_TRIGGER_RSN_FE) from a downstream device,
log the Error Source ID (decoded into domain/bus/device/function). Don't
print the source otherwise, since it's not valid.
For DPC trigger due to reception of ERR_NONFATAL or ERR_FATAL, the dmesg
logging changes:
- pci 0000:00:01.0: DPC: containment event, status:0x000d source:0x0200
- pci 0000:00:01.0: DPC: ERR_FATAL detected
+ pci 0000:00:01.0: DPC: containment event, status:0x000d, ERR_FATAL received from 0000:02:00.0
and when DPC triggered for other reasons, where DPC Error Source ID is
undefined, e.g., unmasked uncorrectable error:
- pci 0000:00:01.0: DPC: containment event, status:0x0009 source:0x0200
- pci 0000:00:01.0: DPC: unmasked uncorrectable error detected
+ pci 0000:00:01.0: DPC: containment event, status:0x0009: unmasked uncorrectable error detected
Previously the "containment event" message was at KERN_INFO and the
"%s detected" message was at KERN_WARNING. Now the single message is at
KERN_WARNING.

Commit 2031c469f816 ("iommu/vt-d: Add support for static identity domain")
changed the context entry setup during domain attachment from a
set-and-check policy to a clear-and-reset approach. This inadvertently
introduced a regression affecting PCI aliased devices behind PCIe-to-PCI
bridges.
Specifically, keyboard and touchpad stopped working on several Apple
Macbooks with below messages:

When booting a board to NAND and accessing NAND while eMMC
transactions are occurring the NAND will sometimes timeout. This
is due to both NAND and eMMC controller sharing the same data bus
on BCMBCA chips. Fix is to extend NAND timeout to allow eMMC
transactions time to complete.

The platform profile driver is loaded even on platforms that do not have
ACPI enabled. The initialization of the sysfs entries was recently moved
from platform_profile_register() to the module init call, and those
entries need acpi_kobj to be initialized which is not the case when ACPI
is disabled.
This results in the following warning:
WARNING: CPU: 5 PID: 1 at fs/sysfs/group.c:131 internal_create_group+0xa22/0xdd8

Rust kernel code is supposed to use the custom mapping of C FFI types,
i.e. those from the `ffi` crate, rather than the ones coming from `core`.
Thus, to minimize mistakes and to simplify the code everywhere, just
provide them in the `kernel` prelude and ask in the Coding Guidelines
to use them directly, i.e. as a single segment path.
After this lands, we can start cleaning up the existing users.
Ideally, we would use something like Clippy's `disallowed-types` to
prevent the use of the `core` ones, but that one sees through aliases.

SND_USB_AUDIO_QMI depends on USB_XHCI_SIDEBAND, but that is a bool symbol
and allows it to be built-in even when XHCI itself is in a loadable module.
That configuration causes a link failure:

The driver does not support legacy board files, so the of_match_ptr()

Extend the #ifdef block a little further to cover all of these functions.
Ideally we'd use use if(IS_ENABLED()) instead, but that doesn't currently
work because the i2c_transfer() and i2c_smbus_write_word_data() function
declarations are hidden when CONFIG_I2C is disabled.
