Pull irq updates from Thomas Gleixner:
"Updates to the interrupt core and driver subsystems:
Core changes:
- The usual set of small fixes and improvements all over the place,
but nothing stands out
MSI changes:
- Further consolidation of the PCI/MSI interrupt chip code
- Make MSI sysfs code independent of PCI/MSI and expose the MSI
interrupts of platform devices in the same way as PCI exposes them.
Driver changes:
- Support for ARM GICv3 EPPI partitions
- Treewide conversion to generic_handle_domain_irq() for all chained
interrupt controllers
- Conversion to bitmap_zalloc() throughout the irq chip drivers
- The usual set of small fixes and improvements"

Retrieve and print retry_rd_err_log registers like the earlier change:
commit e80634a75aba ("EDAC, skx: Retrieve and print retry_rd_err_log registers")
This is a little trickier than on Skylake because of potential
interference with BIOS use of the same registers. The default
behavior is to ignore these registers.
A module parameter retry_rd_err_log(default=0) controls the mode of operation:
- 0=off : Default.
- 1=bios : Linux doesn't reset any control bits, but just reports values.
This is "no harm" mode, but it may miss reporting some data.
- 2=linux: Linux tries to take control and resets mode bits,
clears valid/UC bits after reading. This should be
more reliable (especially if BIOS interference is reduced
by disabling eMCA reporting mode in BIOS setup).

MCDDRCFG is a per-channel register and uses bit{0,1} to indicate
the NVDIMM presence on DIMM slot{0,1}. Current i10nm_edac driver
wrongly uses MCDDRCFG as per-DIMM register and fails to detect
the NVDIMM.
Fix it by reading MCDDRCFG as per-channel register and using its
bit{0,1} to check whether the NVDIMM is populated on DIMM slot{0,1}.

The Altera EDAC driver has several features conditionally built
depending on Kconfig options. The edac_device_prv_data structures
are conditionally used in of_device_id tables. They reference other
functions and structures which can be defined as __maybe_unused.
Silence build warnings like:
drivers/edac/altera_edac.c:643:37: warning:
‘altr_edac_device_inject_fops’ defined but not used [-Wunused-const-variable=]

Hypervisors likely do not expose the SMCA feature to the guest and
loading this module leads to false warnings. This module should not be
loaded in guests to begin with, but people tend to do so, especially
when testing kernels in VMs. And then they complain about those false
warnings.
Do the practical thing and do not load this module when running as a
guest to avoid all that complaining.

Instead of "open coding" DEVICE_ATTR, use the corresponding
helper macros DEVICE_ATTR_{RW,RO,WO} in amd64_edac.c
Some function names needed to be changed to match the device
conventions <foo>_show and <foo>_store, but the functionality
itself is unchanged.
The devices using EDAC_DCT_ATTR_SHOW() are left unchanged.

kernel.h is being used as a dump for all kinds of stuff for a long time.
Here is the attempt to start cleaning it up by splitting out panic and
oops helpers.
There are several purposes of doing this:
- dropping dependency in bug.h
- dropping a loop by moving out panic_notifier.h
- unload kernel.h from something which has its own domain
At the same time convert users tree-wide to use new headers, although for
the time being include new header back to kernel.h to avoid twisted
indirected includes for existing users.

There's little to no point in loading an EDAC driver running in a guest:
1) The CPU model reported by CPUID may not represent actual h/w
2) The hypervisor likely does not pass in access to memory controller devices
3) Hypervisors generally do not pass corrected error details to guests
Add a check in each of the Intel EDAC drivers for X86_FEATURE_HYPERVISOR
and simply return -ENODEV in the init routine.

Alder Lake SoC shares the same memory controller and In-Band ECC
(IBECC) IP with Tiger Lake SoC. Like Tiger Lake, it also has two
memory controllers each associated one IBECC instance. The minor
differences include the MMIO offset of each memory controller and
the type of memory error address logged in the IBECC.
So add Alder Lake compute die IDs, adjust the MMIO offset for each
memory controller and handle the type of memory error address logged
in the IBECC for Alder Lake EDAC support.

Current i10nm_edac driver is only for system configured in 1-level
memory. If the system is configured in 2-level memory, the driver
doesn't report the 1st level memory DIMM for the error address, even
if the error occurs in the 1st level memory.
Both Ice Lake servers and Sapphire Rapids servers can be configured
in 2-level memory. Add detection of memory levels to i10nm_edac for
the two kinds of servers so that the driver can report the 2nd level
memory DIMM or the 1st level memory DIMM according to error source.

Some Intel servers may configure memory in 2 levels, using
fast "near" memory (e.g. DDR) as a cache for larger, slower,
"far" memory (e.g. 3D X-point).
In these configurations the BIOS ADXL address translation for
an address in a 2-level memory range will provide details of
both the "near" and far components.
Current exported ADXL components are only for 1-level memory
system or for 2nd level memory of 2-level memory system. So
add new ADXL components for 1st level memory of 2-level memory
system to fully support 2-level memory system and the detection
of memory error source(1st level memory or 2nd level memory).

amd64_edac was converted to CPU family autoprobing (from PCI device

platform_get_irq() will already print an error message when it is unable
to get an IRQ.
Use platform_get_irq_optional() instead which avoids the error message
and keep the driver-specific one.

Families up to and including 0x16 allow access to the injection
hardware. Starting with family 0x17, access to those registers is
blocked by security policy.
Limit that only on the families which support it.

Merge them into the main driver and put them inside an EDAC_DEBUG
ifdeffery to simplify the driver and have all debugging/injection stuff
behind a debug build-time switch.

There's no need for them to be in a separate file so merge them into the
main driver compilation unit like the other EDAC drivers do.
Drop now-unneeded function export, make the function static and shorten
static function names.
No functional changes.

Give these messages a debug severity as they are really only useful to
the module developers.
Also, drop the "(broken BIOS?)" phrase, since this can cause churn for
BIOS folks. The PCI IDs needed by the module, at least on modern systems,
are fixed in hardware.

Those were only laptops and are very very unlikely to have ECC memory.
Currently, when the driver attempts to load, it issues:
EDAC amd64: Error: F1 not found: device 0x1601 (broken BIOS?)
because the PCI device is the wrong one (it uses the F15h default one).
So do not load the driver on them as that is pointless.

The mv64x60 EDAC driver depends on CONFIG_MV64X60. But that symbol is
not user-selectable, and the last code that selected it was removed
with the C2K board support in 2018, see:
92c8c16f3457 ("powerpc/embedded6xx: Remove C2K board support")
That means the driver is now dead code, so remove it.

In order to setup its PCI component, the driver needs any node private
instance in order to get a reference to the PCI device and hand that
into edac_pci_create_generic_ctl(). For convenience, it uses the 0th
memory controller descriptor under the assumption that if any, the 0th
will be always present.
However, this assumption goes wrong when the 0th node doesn't have
memory and the driver doesn't initialize an instance for it:
EDAC amd64: F17h detected (node 0).
...
EDAC amd64: Node 0: No DIMMs detected.
But looking up node instances is not really needed - all one needs is
the pointer to the proper device which gets discovered during instance
init.
So stash that pointer into a variable and use it when setting up the
EDAC PCI component.
Clear that variable when the driver needs to unwind due to some
instances failing init to avoid any registration imbalance.

The Sapphire Rapids CPU model shares the same memory controller
architecture with Ice Lake server. There are some configurations
different from Ice Lake server as below:
- The device ID for configuration agent.
- The size for per channel memory-mapped I/O.
- The DDR5 memory support.
So add the above configurations and the Sapphire Rapids CPU model
ID for EDAC support.

Add debugfs support to fake memory correctable errors to test the
error reporting path and the error address decoding logic in the
igen6_edac driver.
Please note that the fake errors are also reported to EDAC core and
then the CE counter in EDAC sysfs is also increased.
