Benjamin Herrenschmidt pointed out that I further missed modifying
update_vsyscall after the wall_to_mono value was changed to a
timespec64.  This causes issues on powerpc32, which expects a 32bit
timespec.

This patch fixes the problem by properly converting from a timespec64 to
a timespec before passing the value on to the arch-specific vsyscall
logic.

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"

  Group changes to the device tree.  In preparation for adding device

  tree changes can be prepared and applied to the tree all at once.
  OF_RECONFIG notifiers see the most significant change here so that
  users always get a consistent view of the tree.  Notifiers generation
  is moved from before a change to after it, and notifiers for a group
  of changes are emitted after the entire block of changes have been
  applied

  Automatic console selection from DT.  Console drivers can now use
  of_console_check() to see if the device node is specified as a console
  device.  If so then it gets added as a preferred console.  UART
  devices get this support automatically when uart_add_one_port() is
  called.

  DT unit tests no longer depend on pre-loaded data in the device tree.
  Data is loaded dynamically at the start of unit tests, and then
  unloaded again when the tests have completed.

Pull x86/apic updates from Thomas Gleixner:
 "This is a major overhaul to the x86 apic subsystem consisting of the
  following parts:

   - Remove obsolete APIC driver abstractions (David Rientjes)

   - Use the irqdomain facilities to dynamically allocate IRQs for
     IOAPICs.  This is a prerequisite to enable IOAPIC hotplug support,
     and it also frees up wasted vectors (Jiang Liu)

   - Misc fixlets.

  Despite the hickup in Ingos previous pull request - caused by the
  missing fixup for the suspend/resume issue reported by Borislav - I
  strongly recommend that this update finds its way into 3.17.  Some
  history for you:

  This is preparatory work for physical IOAPIC hotplug.  The first
  attempt to support this was done by Yinghai and I shot it down because
  it just added another layer of obscurity and complexity to the already
  existing mess without tackling the underlying shortcomings of the
  current implementation.

  After quite some on- and offlist discussions, I requested that the
  design of this functionality must use generic infrastructure, i.e.
  irq domains, which provide all the mechanisms to dynamically map linux
  interrupt numbers to physical interrupts.

  Jiang picked up the idea and did a great job of consolidating the
  existing interfaces to manage the x86 (IOAPIC) interrupt system by
  utilizing irq domains.

  The testing in tip, Linux-next and inside of Intel on various machines
  did not unearth any oddities until Borislav exposed it to one of his
  oddball machines.  The issue was resolved quickly, but unfortunately
  the fix fell through the cracks and did not hit the tip tree before
  Ingo sent the pull request.  Not entirely Ingos fault, I also assumed
  that the fix was already merged when Ingo asked me whether he could
  send it.

  Nevertheless this work has a proper design, has undergone several
  rounds of review and the final fallout after applying it to tip and
  integrating it into Linux-next has been more than moderate.  It's the
  ground work not only for IOAPIC hotplug, it will also allow us to move
  the lowlevel vector allocation into the irqdomain hierarchy, which
  will benefit other architectures as well.  Patches are posted already,
  but they are on hold for two weeks, see below.

  I really appreciate the competence and responsiveness Jiang has shown
  in course of this endavour.  So I'm sure that any fallout of this will
  be addressed in a timely manner.

  FYI, I'm vanishing for 2 weeks into my annual kids summer camp kitchen
  duty^Wvacation, while you folks are drooling at KS/LinuxCon :) But HPA
  will have a look at the hopefully zero fallout until I'm back"

On ppc64 we support 4K hash pte with 64K page size. That requires
us to track the hash pte slot information on a per 4k basis. We do that
by storing the slot details in the second half of pte page. The pte bit
_PAGE_COMBO is used to indicate whether the second half need to be
looked while building real_pte. We need to use read memory barrier while
doing that so that load of hidx is not reordered w.r.t _PAGE_COMBO
check. On the store side we already do a lwsync in __hash_page_4K

As per ISA, for 4k base page size we compare 14..65 bits of VA specified
with the entry_VA in tlb. That implies we need to make sure we do a
tlbie with all the possible 4k va we used to access the 16MB hugepage.
With 64k base page size we compare 14..57 bits of VA. Hence we cannot
ignore the lower 24 bits of va while tlbie .We also cannot tlb
invalidate a 16MB entry with just one tlbie instruction because
we don't track which va was used to instantiate the tlb entry.

If we changed base page size of the segment, either via sub_page_protect
or via remap_4k_pfn, we do a demote_segment which doesn't flush the hash
table entries. We do a lazy hash page table flush for all mapped pages
in the demoted segment. This happens when we handle hash page fault for
these pages.

We use _PAGE_COMBO bit along with _PAGE_HASHPTE to indicate whether a
pte is backed by 4K hash pte. If we find _PAGE_COMBO not set on the pte,
that implies that we could possibly have older 64K hash pte entries in
the hash page table and we need to invalidate those entries.

Use _PAGE_COMBO to determine the page size with which we should
invalidate the hash table entries on unmap.
