    Pull x86 idle updates from Ingo Molnar:
     "There were two bigger changes in this development cycle:
    
       - remove idle notifiers:
    
           32 files changed, 74 insertions(+), 803 deletions(-)
    
         These notifiers were of questionable value and the main usecase,
         the i7300 driver, was essentially unmaintained and can be removed,
         plus modern power management concepts don't need the callback - so
         use this golden opportunity and get rid of this opaque and fragile
         callback from a latency sensitive code path.
    
         (Len Brown, Thomas Gleixner)
    
       - improve the AMD Erratum 400 workaround that used high overhead MSR
         polling in the idle loop (Borisla Petkov, Thomas Gleixner)"
