Hi Johannes,
FYI, the error/warning was bisected to this commit, please ignore it if it's irrelevant.
tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master head: b78b18fb8ee19f7a05f20c3abc865b3bfe182884 commit: e6d429313ea5c776d2e76b4494df69102e6b7115 x86/resctrl: Avoid confusion over the new X86_RESCTRL config date: 4 years, 8 months ago config: x86_64-randconfig-003-20230909 (https://download.01.org/0day-ci/archive/20231006/202310062356.lX3xpLP9-lkp@intel.com/config) compiler: gcc-9 (Debian 9.3.0-22) 9.3.0 reproduce (this is a W=1 build): (https://download.01.org/0day-ci/archive/20231006/202310062356.lX3xpLP9-lkp@intel.com/reproduce)
