Subject: [PATCH 4/5] intel_idle: Revert change of auto_demotion_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_flags for the former to
0.  This was not explained in the commit message, so change it back.

Signed-off-by: Ben Hutchings <ben@...adent.org.uk>

I have very little idea what I'm doing here...

Ben.
