Pull forgotten EDAC updates from Borislav Petkov: "Somewhat belated (and forgotten :-\) EDAC updates lineup for v7.3: - Mark the mpc85xx and ThunderX EDAC drivers as orphaned due to lack of access to hardware - Remove the unused fake error injection interface from the EDAC debugfs code due to potential races between logging a fake and a real hw error - edac_mc_sysfs: Use sysfs_emit_at() for proper bounds checking - Remove Mark Gross from maintainer entries and move him to CREDITS - Load the AMD address translation library only on systems which can actually make use of it (have ECC memory) instead of on every AMD Zen system out there - In edac_altera, detect the SoC variant using the ECC manager's compatible string instead of the build architecture to select the correct interrupt layout, and remove leftover architecture-specific ifdeffery from the double-bit error handling path - Add a new reviewer for the Xilinx EDAC drivers - Unify address translation logic in Intel client EDAC drivers igen6 and ie31200 along with detecting memory controller counts at boot time instead of relying on hardcoded, platform specific numbers. Also, fix a bunch of issues in them; work by Qiuxu Zhuo - Add support for a new Intel processor platform Starfire which is a derivative of Panther Lake SoCs - The usual cleanups and fixlets all over" * tag 'edac_updates_for_v7.3_rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/ras/ras: (24 commits) EDAC/thunderx: Orphan it EDAC/device_sysfs: Cleanup around edac_device_ctl_poll_msec_store() EDAC/device_sysfs: Use kstrtouint() for poll_msec to prevent truncation EDAC/igen6: Add Intel Starfire SoCs support EDAC/igen6: Refactor address translation logic EDAC/igen6: Remove redundant resource configuration tables EDAC/igen6: Detect present memory controllers at runtime EDAC/igen6: Simplify compute die ID comments EDAC/igen6: Remove unnecessary XOR on the zero-valued interleave bit EDAC/igen6: Fix Raptor Lake-P logged error address EDAC/igen6: Fix channel address decode for non-hash mode EDAC/igen6: Fix channel selection hash EDAC/igen6: Fix interleave boundary condition EDAC/ie31200: Decouple DIMM width decoding from enum order RAS/AMD/ATL: Remove conditional return with no effect EDAC: Remove redundant dev_err() MAINTAINERS: Add Radhey Shyam Pandey as Xilinx EDAC reviewer EDAC/altera: Remove remaining CONFIG_64BIT ifdefs in the DB-error path EDAC/altera: Use ECC manager compatible to select A10/S10 IRQ layout RAS/AMD/ATL, EDAC/amd64: Only load ATL when needed ...

RAS/AMD/ATL: Remove conditional return with no effect

2026-07-23T19:23:05+00:00

Both branches of the check return the same value, so the check has no effect. Remove it and return the value directly. This is the result of running the Coccinelle script from scripts/coccinelle/misc/cond_return_no_effect.cocci.

RAS/AMD/ATL, EDAC/amd64: Only load ATL when needed

2026-07-08T02:45:05+00:00

The AMD Address Translation Library (ATL) will attempt to load on all AMD Zen/SMCA systems. However, only systems with DRAM ECC enabled will use the library. Other systems will fail to load the library and produce an unnecessary message to the user. More importantly, that thing is dead code loaded and unused. Remove the ATL module dependency table to prevent autoloading. Request ATL to load from EDAC once all system checks are complete.

x86/ras: Move contents from arch/x86/ras/Kconfig into drivers/ras/Kconfig

2026-07-02T01:40:09+00:00

Commit bc8e80d56c1ec ("x86/mce: Merge mce_amd_inj into mce-inject") removed the last .c file from arch/x86/ras/, so that there is now only a lonely Kconfig file in this folder. Its config switches CONFIG_RAS_CEC and CONFIG_RAS_CEC_DEBUG are only used in code that resides in drivers/ras/, so those Kconfig switches should better reside in drivers/ras/, too. Thus move the contents of arch/x86/ras/ into drivers/ras/Kconfig now.

RAS/AMD/ATL: Drop malformed default N from Kconfig

2026-05-14T11:24:51+00:00

The capital letters are for symbols and N in 'default N' will be evaluated as another, nonexistent, Kconfig symbol, and not as the 'no' it should be. More importantly, 'n' *is* the default already. Hence just drop the malformed line. Signed-off-by: Andy Shevchenko Signed-off-by: Borislav Petkov (AMD) Link: https://patch.msgid.link/20260513205021.368190-1-andriy.shevchenko@linux.intel.com

treewide: Explicitly include the x86 CPUID headers

2026-05-06T12:29:59+00:00

Modify all CPUID call sites which implicitly include any of the CPUID headers to explicitly include them instead. For KVM's reverse_cpuid.h, just include since it references the CPUID_EAX..EDX symbols without using the CPUID APIs. Note, this allows removing the inclusion of from within next. That allows the CPUID API headers to include without introducing a circular dependency. Signed-off-by: Ahmed S.

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook
