Pull powerpc fixes from Ben Herrenschmidt:
 "Here are 3 bug fixes that should probably go into 3.11 since I'm also
  tagging them for stable.

  Once fixes our old /proc/powerpc/lparcfg file which provides partition
  informations when running under our hypervisor and also acts as a
  user-triggerable Oops when hot :-(

  The other two respectively are a one liner to fix a HVSI protocol
  handshake problem causing the console to fail to show up on a bunch of
  machines until we reach userspace, which I deem annoying enough to
  warrant going to stable, and a nasty gcc miscompile causing us to pass
  virtual instead of physical addresses to the firmware under some
  circumstances"

* 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc:
  powerpc/hvsi: Increase handshake timeout from 200ms to 400ms.
  powerpc: Work around gcc miscompilation of __pa() on 64-bit
  powerpc: Don't Oops when accessing /proc/powerpc/lparcfg without hypervisor

Dave reported corrupted swap entries

and Hugh pointed that in move_ptes _PAGE_SOFT_DIRTY bit set regardless
the type of entry pte consists of.  The trick here is that when we carry
soft dirty status in swap entries we are to use _PAGE_SWP_SOFT_DIRTY
instead, because this is the only place in pte which can be used for own
needs without intersecting with bits owned by swap entry type/offset.

This solves a problem observed in kexec'ed kernel where 200ms timeout is
too short and bootconsole fails to initialize. Console did eventually
become workable but much later into the boot process.

Observed timeout was around 260ms, but I decided to make it a little bigger
for more reliability.

This has been tested on Power7 machine with Petitboot as a primary
bootloader and PowerNV firmware.

On 64-bit, __pa(&static_var) gets miscompiled by recent versions of
gcc as something like:

        addis 3,2,.LANCHOR1+4611686018427387904@toc@ha
        addi 3,3,.LANCHOR1+4611686018427387904@toc@l

This ends up effectively ignoring the offset, since its bottom 32 bits
are zero, and means that the result of __pa() still has 0xC in the top
nibble.  This happens with gcc 4.8.1, at least.

To work around this, for 64-bit we make __pa() use an AND operator,
and for symmetry, we make __va() use an OR operator.  Using an AND
operator rather than a subtraction ends up with slightly shorter code
since it can be done with a single clrldi instruction, whereas it
takes three instructions to form the constant (-PAGE_OFFSET) and add
it on.  (Note that MEMORY_START is always 0 on 64-bit.)

/proc/powerpc/lparcfg is an ancient facility (though still actively used)
which allows access to some informations relative to the partition when
running underneath a PAPR compliant hypervisor.

It makes no sense on non-pseries machines. However, currently, not only
can it be created on these if the kernel has pseries support, but accessing
it on such a machine will crash due to trying to do hypervisor calls.

In fact, it should also not do HV calls on older pseries that didn't have
an hypervisor either.

Finally, it has the plumbing to be a module but is a "bool" Kconfig option.

This fixes the whole lot by turning it into a machine_device_initcall
that is only created on pseries, and adding the necessary hypervisor
check before calling the H_GET_EM_PARMS hypercall

Being a low-level component, various drivers (e.g.  olpc-battery) assume
that it is ok to communicate with the OLPC Embedded Controller during
probe.  Therefore the OLPC EC driver must be initialised before other
drivers try to use it.  This was the case until it was recently moved
out of arch/x86 and restructured around commits ac250415 ("Platform:
OLPC: turn EC driver into a platform_driver") and 85f90cf6 ("x86:
OLPC: switch over to using new EC driver on x86").

Use arch_initcall so that olpc-ec is readied earlier, matching the
previous behaviour.

Fixes a regression introduced in Linux-3.6 where various drivers such as
olpc-battery and olpc-xo1-sci failed to load due to an inability to
communicate with the EC.  The user-visible effect was a lack of battery
monitoring, missing ebook/lid switch input devices, etc.
