Updating the hysteresis value when updating the critical temperature limit
was following the rule of 'least surprise'. However, it had the undesirable
side effect of changing the hysteresis for all other attributes, which
defeats the purpose of least surprise. In addition, it could result in
invalid hysteresis values if the resulting hysteresis was too large. In such
cases the resulting hysteresis ended up changed anyway, which again defeats
the purpose. So drop that code and document the new behavior.

Pull two powerpc fixes from Ben Herrenschmidt:
 "Here are a couple of fixes for 3.15.  One from Anton fixes a nasty
  regression I introduced when trying to fix a loss of irq_work whose
  consequences is that we can completely lose timer interrupts on a
  CPU... not pretty.

  The other one is a change to our PCIe reset hook to use a firmware
  call instead of direct config space accesses to trigger a fundamental
  reset on the root port.  This is necessary so that the FW gets a
  chance to disable the link down error monitoring, which would
  otherwise trip and cause subsequent fatal EEH error"

  later.

  A couple of the bugs are in data integrity operations, a couple more
  are in the new COLLAPSE_RANGE code.  One of these came in through a
  recent ext4 merge and so I had to update the base tree to 3.15-rc5
