When compiling drivers (speficially drivers/pci/hotplug), I am receiving the following modpost error for both `kmalloc_trace` and `kmalloc_node_trace` on the staging/staging-next branch: ERROR: modpost: "kmalloc_trace" [drivers/pci/hotplug/acpiphp_ibm.ko] undefined! This only occurs when I have 'CONFIG_TRACING=y' in my config, and I have traced it down to the slab header where the kmalloc_trace is defined. It appears that when CONFIG_TRACING is set, the kmalloc_trace and kmalloc_node_trace do not get defined by the compiler. I do not have enough context in this area of the code base to propose a fix or to even know if maybe it's a local compiling issue for myself. It looks like there are a few recent commits from August that did some refactoring in this header, and when compiling prior to that refactoring I am able to compile the specified drivers without error. I will mention that I am using Red Hat gcc version 12.2.1 and make version 4.3 and am on Fedora.
