Agreed.
We started with mwait_idle() -- which was erroneously removed
and is now being restored under it original name.

The "new" function is mwait_idle_with_hints() -- which uses
the additional hints that were not available w/ the original MWAIT instruction.
Where "new" is Core Duo and later -- all the processor that can use
MWAIT for C-states deeper than C1.
