Pull "remoteproc/rpmsg: new subsystem" from Arnd Bergmann:
 "This new subsystem provides a common way to talk to secondary
  processors on an SoC, e.g.  a DSP, GPU or service processor, using
  virtio as the transport.  In the long run, it should replace a few
  dozen vendor specific ways to do the same thing, which all never made
  it into the upstream kernel.  There is a broad agreement that rpmsg is
  the way to go here and several vendors have started working on
  replacing their own subsystems.

  Two branches each add one virtio protocol number.  Fortunately the
  numbers were agreed upon in advance, so there are only context
  changes.

powerpc/eeh: Remove eeh device from OF node

Originally, the PCI sensitive OF node is tracing the eeh device
through struct device_node->edev. However, it was regarded as
bad idea.

The patch removes struct device_node->edev and uses PCI_DN to
trace the corresponding eeh device according to BenH's comments.

powerpc/eeh: Remove eeh information from pci_dn

The patch removes the eeh information from pci_dn since the eeh
device (struct eeh_dev) already contained those information and
the copy in pci_dn is no longer used except for the pseries iommu
mapping code, which we change to retrieve the PE address from eeh
device instead.

powerpc/eeh: Retrieve PHB from global list

Currently, the existing PHBs are retrieved from the FDT (Flat
Device Tree) based on the name of FDT node. Specificly, those
FDT nodes whose names have prefix "pci" are regarded as PHBs.
That's inappropriate because some PCI bridges possibilly have
names leading with "pci". It caused EEH is enabled on same
PCI devices for towice.

The patch fixes the above issue. Besides, the PHBs are expected
to be figured out from FDT before enable EEH on them. Therefore,
it's resonable to retrieve the PHBs from the global linked list
traced by variable "hose_list" insteading poking them from FDT.

For the EEH implementation on pSeries platform, RTAS is critical
because all low-level functions are implemented based on RTAS.
Therefore, we should make sure "/rtas" OF node is available and
ready before to enable EEH core. However, it actually introduced
duplicate since the previous pSeries platform dependent initialization
function already do the check. Besides, we want to make eeh core
platform independent, so RTAS related staff should be removed there.
The patch removes the duplicate check on "/rtas" OF node for eeh
core.

powerpc: Make function that parses RTAS error logs global

The IO event interrupt code has a function that finds specific
sections in an RTAS error log. We want to use it in the EPOW

find_xelog_section() -> get_pseries_errorlog()
struct pseries_elog_section -> struct pseries_errorlog

powerpc/pseries: Parse and handle EPOW interrupts

We have code to take environmental and power warning (EPOW)
interrupts but it simply prints a terse error message:

EPOW <0x6240040000000b8 0x0 0x0>

which tells us nothing about what happened. Even worse, if we
don't correctly respond to the interrupt we may get terminated
by firmware.

Add code to printk some useful information when we get EPOW events.
We want to make it clear that we have an error, that it was
reported by firmware and that the RTAS error log will have more
detailed information. eg:

	Ambient temperature too high reported by firmware.
	Check RTAS error log for details

Depending on the error encountered, we now issue an immediate or
an orderly power down.

Move initialization of the EPOW interrupt earlier in boot since we
want to respond to them as early as possible.

powerpc/perf: Fix instruction address sampling on 970 and Power4

970 and Power4 don't support "continuous sampling" which means that
when we aren't in marked instruction sampling mode (marked events),
SIAR isn't updated with the last instruction sampled before the
perf interrupt. On those processors, we must thus use the exception
SRR0 value as the sampled instruction pointer.

Those processors also don't support the SIPR and SIHV bits in MMCRA
which means we need some kind of heuristic to decide if SIAR values
represent kernel or user addresses.

Pull ARM platform updates from Russell King:
 "This covers platform stuff for platforms I have a direct interest in
  (iow, I have the hardware).  Essentially:
   - as we no longer support any other Acorn platforms other than RiscPC
     anymore, we can collect all that code into mach-rpc.
   - convert Acorn expansion card stuff to use IRQ allocation functions,
     and get rid of NO_IRQ from there.
   - cleanups to the ebsa110 platform to move some private stuff out of
     its header files.
   - large amount of SA11x0 updates:
   - conversion of private DMA implementation to DMA engine support
     (this actually gives us greater flexibility in drivers over the old
     API.)
   - re-worked ucb1x00 updates - convert to genirq, remove sa11x0
     dependencies, fix various minor issues
   - move platform specific sa11x0 framebuffer data into platform files
     in arch/arm instead of keeping this in the driver itself
   - update sa11x0 IrDA driver for DMA engine, and allow it to use DMA
     for SIR transmissions as well as FIR
   - rework sa1111 support for genirq, and irq allocation
   - fix sa1111 IRQ support so it works again
   - use sparse IRQ support

  After this, I have one more pull request remaining from my current
  set, which I think is going to be the most problematical as it
  generates 8 conflicts."
