struct pci_io_addr_range{} stores the information of pci resources. It
would be better to keep these related fields have the same type as in
struct resource{}.
This patch fixes the start/end/flags type in struct pci_io_addr_range{} to
have the same type as in struct resource{}.

The patch removes struct eeh_dev::dn and the corresponding helper
functions: eeh_dev_to_of_node() and of_node_to_eeh_dev(). Instead,
eeh_dev_to_pdn() and pdn_to_eeh_dev() should be used to get the
pdn, which might contain device_node on PowerNV platform.

pr_warn() is equal to pr_warning(), but the former is a bit more
formal according to commit fc62f2f ("kernel.h: add pr_warn for
symmetry to dev_warn, netdev_warn").
The patch replaces pr_warning() with pr_warn().

There are multiple global EEH flags. Almost each flag has its own
accessor, which doesn't make sense. The patch refactors EEH flag
accessors so that they look unified:
eeh_add_flag(): Add EEH flag
eeh_clear_flag(): Clear EEH flag
eeh_has_flag(): Check if one specific flag has been set
eeh_enabled(): Check if EEH functionality has been enabled

We will rely on pcibios_release_device() to remove the EEH cache
and unbind EEH device for the specific PCI device. So we shouldn't
hold the reference to the PCI device from EEH cache and EEH device.
Otherwise, pcibios_release_device() won't be called as we expected.
The patch removes the reference to the PCI device in EEH core.

Merge tag 'v3.10' into next
Merge 3.10 in order to get some of the last minute powerpc
changes, resolve conflicts and add additional fixes on top
of them.
The patch is for avoiding following build warnings:
The function .pnv_pci_ioda_fixup() references
the function __init .eeh_init().
This is often because .pnv_pci_ioda_fixup lacks a __init
The function .pnv_pci_ioda_fixup() references
the function __init .eeh_addr_cache_build().
This is often because .pnv_pci_ioda_fixup lacks a __init

On the PowerNV platform, the EEH address cache isn't built correctly
because we skipped the EEH devices without binding PE. The patch
fixes that.

The patch moves the common part of EEH core into arch/powerpc/kernel
directory so that we needn't PPC_PSERIES while compiling POWERNV
platform:
* Move the EEH common part into arch/powerpc/kernel
* Move the functions for PCI hotplug from pSeries platform to
arch/powerpc/kernel/pci-hotplug.c
* Move CONFIG_EEH from arch/powerpc/platforms/pseries/Kconfig to
arch/powerpc/platforms/Kconfig
* Adjust makefile accordingly
