As the comment of pci_get_domain_bus_and_slot() says, it returns
a PCI device with refcount incremented, so it doesn't need to
call an extra pci_dev_get() in pci_get_dev_wrapper(), and the PCI
device needs to be put in the error path.

Newer AMD systems, such as Genoa, can support up to 12 channels per EDAC
"mc" device. These are detected by the device's EDAC module, and the
current EDAC interface is properly enumerated. However, the legacy EDAC
sysfs interface provides device attributes only for channels 0 to 7.
Therefore, channels 8 to 11 will not be visible in the legacy interface.
This was overlooked in the initial support for AMD Genoa.
Add additional device attributes so that up to 12 channels are visible
in the legacy EDAC sysfs interface.

Call ghes_get_devices() to check whether ghes_edac should be used on the
platform where it is preferred over the corresponding chipset-specific
EDAC driver.
Unlike the existing edac_get_owner() check, the ghes_get_devices() check
works independent to the module_init ordering.

Commit
dc4e8c07e9e2 ("ACPI: APEI: explicit init of HEST and GHES in apci_init()")
introduced a bug leading to ghes_edac_register() to be invoked before
edac_init(). Because at that time the bus "edac" hadn't been even
registered, this created sysfs nodes as /devices/mc0 instead of
/sys/devices/system/edac/mc/mc0 on an Ampere eMag server.
Fix this by turning ghes_edac into a proper module.
The list of GHES devices returned is not protected from being modified
concurrently but it is pretty static as it gets created only during GHES
init and latter is not a module so...

To make ghes_edac a proper module, prepare to decouple its dependencies
from GHES.
Move the ghes_edac.force_load parameter to ghes.c in order to
properly control whether ghes_edac should be force-loaded: In
ghes_edac_register() it is too late to set the module flag.
Introduce a helper ghes_get_devices(), which returns the list of GHES
devices which got probed when the platform-check passes on the system.
The previous force_load check is not needed in ghes_edac_unregister()
since it will be checked in the module's init function of ghes_edac
later.

In order to make it a proper module and disentangle it from facilities,
add a notifier for reporting memory errors. Use an atomic notifier
because calls sites like ghes_proc_in_irq() run in interrupt context.

Current i10nm_edac only supports firmware decoder (ACPI DSM methods).
MCA bank registers of Ice Lake or Tremont CPUs contain the information
to decode DDR memory errors. To get better decoding performance, add
the driver decoder (decoding DDR memory errors via extracting error
information from MCA bank registers) for Ice Lake and Tremont CPUs.

The performance of driver decoder[1] is better than the performance
of firmware decoder[2], especially on frequent correctable errors.
So use the driver decoder first, fall back to firmware decoder if
the driver decoder is unavailable. Also rename the function pointer
skx_decode to driver_decode (better name to contrast with adxl_decode).

memory controllers and/or MCA bank registers.

The commit
cb51a371d08e ("EDAC/ghes: Setup DIMM label from DMI and use it in error reports")
enforced that both the bank and device strings passed to
dimm_setup_label() are not NULL.
However, there are BIOSes, for example on a
HPE ProLiant DL360 Gen10/ProLiant DL360 Gen10, BIOS U32 03/15/2019
which don't populate both strings:
Handle 0x0020, DMI type 17, 84 bytes
Memory Device
Array Handle: 0x0013
Error Information Handle: Not Provided
Total Width: 72 bits
Data Width: 64 bits
Size: 32 GB
Form Factor: DIMM
Set: None
Locator: PROC 1 DIMM 1 <===== device
Bank Locator: Not Specified <===== bank
This results in a buffer overflow because ghes_edac_register() calls
strlen() on an uninitialized label, which had non-zero values left over
from krealloc_array():
detected buffer overflow in __fortify_strlen

The label contains garbage because the commit in Fixes reallocs the
DIMMs array while scanning the system but doesn't clear the newly
allocated memory.
Change dimm_setup_label() to always initialize the label to fix the
issue. Set it to the empty string in case BIOS does not provide both
bank and device so that ghes_edac_register() can keep the default label
given by edac_mc_alloc_dimms().

zynqmp_get_error_info() writes 0 to the ECC_CLR_OFST register after
an interrupt for a {un-,}correctable error is raised, which disables
the error interrupts. Then the interrupt handler will be called only
once. Therefore, re-enable the error interrupt line at the end of
intr_handler() for v3.x Synopsys EDAC DDR.

Pull EDAC updates from Borislav Petkov:
- Switch ghes_edac to use the CPER error reporting routines and
simplify the code considerably this way
- Rip out the silly edac_align_ptr() contraption which was computing
the size of the private structures of each driver and thus allowing
for a one-shot memory allocation. This was clearly unnecessary and
confusing so switch to simple and boring kmalloc* calls.
- Last but not least, the usual garden variety of fixes, cleanups and
improvements all over EDAC land

The dmc520 driver requires that at least one interrupt line, out of the
ten possible, is configured. The driver prints an error and returns
-EINVAL from its .probe function if there are no interrupt lines
configured.
Don't print a KERN_ERR level message for each interrupt line that's
unconfigured as that can confuse users into thinking that there is an
error condition.
Before this change, the following KERN_ERR level messages would be
reported if only dram_ecc_errc and dram_ecc_errd were configured in the
device tree:
dmc520 68000000.dmc: IRQ ram_ecc_errc not found
dmc520 68000000.dmc: IRQ ram_ecc_errd not found
