Commit 598afa0504 ("kbuild: warn objects shared among multiple modules")
was added to track down cases where the same object is linked into
multiple modules. This can cause serious problems if some modules are
builtin while others are not.

That test triggers this warning:

scripts/Makefile.build:236: drivers/edac/Makefile: skx_common.o is added to multiple modules: i10nm_edac skx_edac

Make this a separate module instead.

591c946675 EDAC/synopsys: Fix ECC status and IRQ control race condition
The race condition around the ECCCLR register access happens in the IRQ
disable method called in the device remove() procedure and in the ECC IRQ
handler:

  1. Enable IRQ:
     a. ECCCLR = EN_CE | EN_UE
  2. Disable IRQ:
     a. ECCCLR = 0
  3. IRQ handler:
     a. ECCCLR = CLR_CE | CLR_CE_CNT | CLR_CE | CLR_CE_CNT
     b. ECCCLR = 0
     c. ECCCLR = EN_CE | EN_UE

So if the IRQ disabling procedure is called concurrently with the IRQ
handler method the IRQ might be actually left enabled due to the
statement 3c.

The root cause of the problem is that ECCCLR register (which since
v3.10a has been called as ECCCTL) has intermixed ECC status data clear
flags and the IRQ enable/disable flags. Thus the IRQ disabling (clear EN
flags) and handling (write 1 to clear ECC status data) procedures must
be serialised around the ECCCTL register modification to prevent the
race.

So fix the problem described above by adding the spin-lock around the
ECCCLR modifications and preventing the IRQ-handler from modifying the
IRQs enable flags (there is no point in disabling the IRQ and then
re-enabling it again within a single IRQ handler call, see the
statements 3a/3b and 3c above).

4527a2194e EDAC/versal: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.

To improve this, there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

7e3ec62867 x86/cpu/amd: Provide a separate accessor for Node ID
AMD (ab)uses topology_die_id() to store the Node ID information and
topology_max_dies_per_pkg to store the number of nodes per package.

This collides with the proper processor die level enumeration which is
coming on AMD with CPUID 8000_0026, unless there is a correlation between
the two. There is zero documentation about that.

So provide new storage and new accessors which for now still access die_id
and topology_max_die_per_pkg(). Will be mopped up after AMD and HYGON are
converted over.

 major in here this release cycle, just lots of small cleanups and some

 Included in here are:
   - more driver core 'const' cleanups and fixes
   - fw_devlink=rpm is now the default behavior
   - kernfs tiny changes to remove some string functions
   - cpu handling in the driver core is updated to work better on many
     systems that add topologies and cpus after booting
   - other minor changes and cleanups
 
 All of the cpu handling patches have been acked by the respective

Merge tag 'ras_core_for_v6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull x86 RAS updates from Borislav Petkov:

 - Convert the hw error storm handling into a finer-grained, per-bank
   solution which allows for more timely detection and reporting of
   errors

 - Start a documentation section which will hold down relevant RAS
   features description and how they should be used

 - Add new AMD error bank types

 - Slim down and remove error type descriptions from the kernel side of
   error decoding to rasdaemon which can be used from now on to decode
   hw errors on AMD

 - Mark pages containing uncorrectable errors as poison so that kdump
   can avoid them and thus not cause another panic

 - The usual cleanups and fixlets

97d62760e4 drivers: soc: xilinx: add check for platform
Some error event IDs for Versal and Versal NET are different.
Both the platforms should access their respective error event
IDs so use sub_family_code to check for platform and check
error IDs for respective platforms. The family code is passed
via platform data to avoid platform detection again.
Platform data is setup when even driver is registered.

f36be9ce81 EDAC: constantify the struct bus_type usage
In many places in the edac code, struct bus_type pointers are passed
around and then eventually sent to the driver core, which can handle a
constant pointer.  So constantify all of the edac usage of these as well
because the data in them is never modified by the edac code either.

1e92af09fa EDAC/skx_common: Filter out the invalid address
Decoding an invalid address with certain firmware decoders could
cause a #PF (Page Fault) in the EFI runtime context, which could
subsequently hang the system. To make {i10nm,skx}_edac more robust
against such bogus firmware decoders, filter out invalid addresses
before allowing the firmware decoder to process them.

9483aa4491 EDAC/versal: Read num_csrows and num_chans using the correct bitfield macro
Fix the extraction of num_csrows and num_chans. The extraction of the
num_rows is wrong. Instead of extracting using the FIELD_GET it is
calling FIELD_PREP.

The issue was masked as the default design has the rows as 0.
