Retract back most macro definitions which went into the user-visible mce.h header. Even though those bits are mostly hardware-defined/-architectural, their naming is not. If we export them to userspace, any kernel unification/renaming/cleanup cannot be done anymore since those are effectively cast in stone. Besides, if userspace wants those definitions, they can write their own defines and go crazy. Signed-off-by: Borislav Petkov <bp@suse.de>
