Artem,
somewhat similarly to the C1E patch, while porting this one to our
driver clone in Xen I've noticed that the code added here would not
be reached in case the user specified a conflicting C1E-related
command line option (which ought to be unrelated to C6 handling).
In my port of the patch I've converted to
/* Check if user prefers C1E over C1. */
if (preferred_states_mask & BIT(2, U) &&
/* Both can't be enabled, stick to the defaults. */
!(preferred_states_mask & BIT(1, U))) {
...
}
Jan

Hi, ack, I'll send a fix for this too.
