rdtgroup_setup_default() is declared at .init.text section, but will be called by resctrl_init() located in the .text section, which will lead to incorrect reference.
Here is the compilation error message reported by linker: WARNING: modpost: vmlinux: section mismatch in reference: resctrl_init+0x6c (section: .text) -> rdtgroup_setup_default (section: .init.text)
