Merge branch 'x86-idle-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

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)"
