From: "Luck, Tony" <tony.luck@intel.com> mainline inclusion from mainline-v5.0-rc1 commit 24c9d423e86b17b25b4b510e81f10aa232fdaa60 category: bugfix bugzilla: https://bugzilla.openeuler.org/show_bug.cgi?id=44 CVE: NA ----------------------------------------------- It was previously noted that Kconfig complained about unmet dependencies when trying to configure skx_edac together with CONFIG_ACPI=n. First fix for this checked for ACPI when doing select ACPI_ADXL but this required stub functions for the case where ACPI wasn't selected. It also allowed building a driver that didn't actually work for a system that has non-volatile DIMMs. Arnd Bergmann pointed out that the right fix is to make EDAC_SKX "depend on ACPI".
