Pull driver core updates from Greg KH: "Here are the set of driver core and kernfs changes for 6.8-rc1. Nothing major in here this release cycle, just lots of small cleanups and some tweaks on kernfs that in the very end, got reverted and will come back in a safer way next release cycle. 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 maintainers and are coming in here in one series. Everything has been in linux-next for a while with no reported issues" * tag 'driver-core-6.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (51 commits) Revert "kernfs: convert kernfs_idr_lock to an irq safe raw spinlock" kernfs: convert kernfs_idr_lock to an irq safe raw spinlock class: fix use-after-free in class_register() PM: clk: make pm_clk_add_notifier() take a const pointer EDAC: constantify the struct bus_type usage kernfs: fix reference to renamed function driver core: device.h: fix Excess kernel-doc description warning driver core: class: fix Excess kernel-doc description warning driver core: mark remaining local bus_type variables as const driver core: container: make container_subsys const driver core: bus: constantify subsys_register() calls driver core: bus: make bus_sort_breadthfirst() take a const pointer kernfs: d_obtain_alias(NULL) will do the right thing... driver core: Better advertise dev_err_probe() kernfs: Convert kernfs_path_from_node_locked() from strlcpy() to strscpy() kernfs: Convert kernfs_name_locked() from strlcpy() to strscpy() kernfs: Convert kernfs_walk_ns() from strlcpy() to strscpy() initramfs: Expose retained initrd as sysfs file fs/kernfs/dir: obey S_ISGID kernel/cgroup: use kernfs_create_dir_ns() ...

EDAC: constantify the struct bus_type usage

2024-01-04T13:34:27+00:00

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.

EDAC/mc: Add support for HBM3 memory type

2023-11-28T15:39:12+00:00

AMD MI300A models use HBM3 (High Bandwidth Memory Gen 3) memory. HBM is a high-speed computer memory interface for 3D-stacked synchronous dynamic random-access memory (SDRAM).

EDAC/mc: Replace spaces with tabs in memtype flags definition

2022-09-01T03:15:51+00:00

Currently, the memory type macros are partly defined with multiple spaces between the macro name and its definition. Replace the spaces with tabs as the kernel coding style requires.
