x86/mm/pat: Export pat_enabled() Two Linux device drivers cannot work with PAT and the work required to make them work is significant. There is not enough motivation to convert these drivers over to use PAT properly, the compromise reached is to let drivers that cannot be ported to PAT check if PAT was enabled and if so fail on probe with a recommendation to boot with the "nopat" kernel parameter.
