Subject: Re: [git pull 2.6.36.stable] intel_idle patches for 2.6.36.stable

Hi Greg,

Please disregard the previous commit log on this thread,
for it was the 2.6.35.y log, while the (smaller) 2.6.36.y log is below.
      
I've added upstream commit id's to each commit comment in this series.
If that is enough to make -stable happy, then we're done.

If you would rather not pull this series because it 
does not exclude the intermediate syntax patches that 
are upstream, then I understand that viewpoint too. 

thanks,
-Len Brown, Intel Open Source Technology Center

please pull from: 

git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux-idle-2.6.git idle-release

This will update the files shown below.

thanks!

ps. a consolidated plain patch is available here:

    intel_idle: do not use the LAPIC timer for ATOM C2
    
    upstream: c25d29952b2a8c9aaf00e081c9162a0e383030cd
    
    If we use the LAPIC timer during ATOM C2 on
    some nvidia chisets, the system stalls.

    intel_idle: delete bogus data from cpuidle_state.power_usage
    
    upstream: dea44c6b7df7f8bb67cb059b4c14b24288c4cd04
    
    The mW data in this field is a total fabrication
    and serves no purpose other than to mislead
    those who might see it in sysfs.  Delete it.

commit bd592a79c7eb1c52b812933dc64a37452b2e9047

    intel_idle: simplify test for leave_mm()
    
    upstream: c8381cc3d8a9cc6c80f65bf60863c776651f245c
    
    A run-time test to invoke leave_mm() for the deepest
    supported C-state is redundant, since the appropriate
    C-states already have flags with CPUIDLE_FLAG_TLB_FLUSHED set.

    x86, mwait: Move mwait constants to a common header file
    
    upstream: bc83cccc761953f878088cdfa682de0970b5561f
    
    We have MWAIT constants spread across three different .c files, for no
    good reason.  Move them all into a common header file.
