Merge tag 'x86_platform_for_6.7_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 platform updates from Borislav Petkov: - Make sure PCI function 4 IDs of AMD family 0x19, models 0x60-0x7f are actually used in the amd_nb.c enumeration - Add support for extracting NUMA information from devicetree for Hyper-V usages - Add PCI device IDs for the new AMD MI300 AI accelerators - Annotate an array in struct uv_rtc_timer_head with the new __counted_by attribute - Rework UV's NMI action parameter handling * tag 'x86_platform_for_6.7_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/amd_nb: Use Family 19h Models 60h-7Fh Function 4 IDs x86/numa: Add Devicetree support x86/of: Move the x86_flattree_get_config() call out of x86_dtb_init() x86/amd_nb: Add AMD Family MI300 PCI IDs x86/platform/uv: Annotate struct uv_rtc_timer_head with __counted_by x86/platform/uv: Rework NMI "action" modparam handling
