RE: RE: \_PR\CPU\_INI not called during initialization

Thank you!  However, I hope you call _INI even if _STA is AE_NOT_FOUND.
See the ASL below to see that there is no _STA method.  If there IS a _STA
method and it returns "not present", it's fine not to call _INI.

For now, I unconditionally call _INI when attaching to a Processor.  It
works and now my mhz and mw settings for performance control are properly
reported.
