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

Hi Greg,

please pull from: 

git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux-idle-2.6.36.git idle-release

to sync 2.6.36.y with upstream changes to the intel_idle driver.

After applying this series, 2.6.36.y and upstream intel_idle.c
are identical.

This will update the files shown below.

thanks!

Len Brown

    intel_idle: do not use the LAPIC timer for ATOM C2
    
    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
    
    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.

    intel_idle: simplify test for leave_mm()
    
    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
    
    We have MWAIT constants spread across three different .c files, for no
    good reason.  Move them all into a common header file.
