Merge tag 'mca_cfg' of git://git.kernel.org/pub/scm/linux/kernel/git/ras/ras into x86/ras
Pull x86 RAS changes from Borislav Petkov: "Rework all config variables used throughout the MCA code and collect them together into a mca_config struct. This keeps them tightly and neatly packed together instead of spilled all over the place. Then, convert those which are used as booleans into real booleans and save some space."
