Hi,

This release breaks my build with the following output:

  LD      .tmp_vmlinux1
ld: drivers/cxl/acpi.o: in function `add_root_nvdimm_bridge':
acpi.c:(.text+0x16f): undefined reference to `devm_cxl_add_nvdimm_bridge'
make[2]: *** [scripts/Makefile.vmlinux:72: vmlinux.unstripped] Error 1
make[1]: *** [/home/cal/linux/kernel/build/linux-6.18.17/Makefile:1242: vmlinux] Error 2
make: *** [Makefile:248: __sub-make] Error 2

I've attached my gzipped config. Commit af9bf9889663 looks possibly 
guilty, but I don't have time at the moment to fully verify.

Please let me know if I can provide anything else.
