Pull powerpc updates from Michael Ellerman:
 "Some nice cleanups like removing bootmem, and removal of
  __get_cpu_var().

  There is one patch to mm/gup.c.  This is the generic GUP
  implementation, but is only used by us and arm(64).  We have an ack
  from Steve Capper, and although we didn't get an ack from Andrew he
  told us to take the patch through the powerpc tree.

  There's one cxl patch.  This is in drivers/misc, but Greg said he was
  happy for us to manage fixes for it.

  There is an infrastructure patch to support an IPMI driver for OPAL.

  There is also an RTC driver for OPAL.  We weren't able to get any
  response from the RTC maintainer, Alessandro Zummo, so in the end we
  just merged the driver.

  The usual batch of Freescale updates from Scott"

<title>of/reconfig: Always use the same structure for notifiers</title>

<id>urn:sha1:f5242e5a883bf1c1aba6bfd87b85e7dda0e62191</id>
<content type='text'>
The OF_RECONFIG notifier callback uses a different structure depending
on whether it is a node change or a property change. This is silly, and
not very safe. Rework the code to use the same data structure regardless
of the type of notifier.

We have an extra level of indirection on memory hot remove which is not
matched on memory hot add. Memory hotplug is book3s only, so there is
no need for it.

This also enables means remove_memory() (ie memory hot unplug) works
on powernv.

Pull powerpc updates from Michael Ellerman:
 "Here's a first pull request for powerpc updates for 3.18.

  The bulk of the additions are for the "cxl" driver, for IBM's Coherent
  Accelerator Processor Interface (CAPI).  Most of it's in drivers/misc,
  which Greg &amp; Arnd maintain, Greg said he was happy for us to take it
  through our tree.

  There's the usual minor cleanups and fixes, including a bit of noise
  in drivers from some of those.  A bunch of updates to our EEH code,
  which has been getting more testing.  Several nice speedups from
  Anton, including 20% in clear_page().

  And a bunch of updates for freescale from Scott"

Values acquired from Open Firmware are in 32-bit big endian format
and need to be handled on little endian architectures.  This patch
ensures values are in cpu endian when hotplugging memory.

Pull more powerpc updates from Ben Herrenschmidt:
 "Here are some more powerpc bits for 3.17, essentially fixes.

  The biggest series, also aimed at -stable, is from Aneesh and is the
  result of weeks and weeks of debugging to find out why the heck or THP
  implementation was occasionally triggering multi-hit errors in our
  level 1 TLB.  It ended up being a combination of issues including
  subtleties as to how we should invalidate those special 'MPSS' pages
  we use to allow the use of 16M pages inside 4K/64K "base page size"
  segments (you really have to love our MMU !)

  Another interesting one in the "OMG" category is the series from
  Michael adding memory barriers to spin_is_locked().  That's also the
  result of many days of debugging to figure out why the semaphore code
  would occasionally crash in ways that made no sense.  It ended up
  being some creative lock stacking that was defeated by the fact that
  our locks allow a load inside the locked section to be re-ordered with
  the load of the lock value itself (I'm still of two mind about whether
  to kill that once and for all by putting a heavier barrier back into
  our lock implementation...).  The fixes come with a long explanation
  in the cset comments, feel free to read it if you feel like having a
  headache today"
