intel_idle: Revert change of auto_demotion_disable_flags for Nehalem
Commit b66b8b9a4a79087dde1b358a016e5c8739ccf186 ('intel-idle: convert to x86_cpu_id auto probing') added a distinction between Nehalem and Westemere processors and changed auto_demotion_disable_flags for the former to 0. This was not explained in the commit message, so change it back. Signed-off-by: Ben Hutchings <ben@decadent.org.uk> Acked-by: Thomas Renninger <trenn@suse.de> Acked-by: H. Peter Anvin <hpa@zytor.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
