In order to allow drivers to specify private data for each controller,
this commit adds a private_data field to the struct hw_pci. This field
is an array of nr_controllers pointers that will be used to initialize
the private_data field of the corresponding controller's pci_sys_data
structure.

into next/cleanup
From Rob Herring:
Initial irqchip init infrastructure and GIC and VIC clean-ups
This creates irqchip initialization infrastructure from Thomas
Petazzoni. The VIC and GIC irqchip code is moved to drivers/irqchips
and adapted to use the new infrastructure. All DT enabled platforms
using GIC and VIC are converted over to use the new irqchip_init.

function as the parent IRQ controller handler function, we provide a

Now that the only field in struct sys_timer is .init, delete the struct,
and replace the machine descriptor .timer field with the initialization
function itself.
This will enable moving timer drivers into drivers/clocksource without
having to place a public prototype of each struct sys_timer object into
include/linux; the intent is to create a single of_clocksource_init()
function that determines which timer driver to initialize by scanning
the device dtree, much like the proposed irqchip_init() at:

These fields duplicate e.g. struct clock_event_device's suspend and
resume fields, so remove them now that nothing is using them. The aim
is to remove all fields from struct sys_timer except .init, then replace
the ARM machine descriptor's .timer field with a .init_time function
instead, and delete struct sys_timer.

remove ARM's struct sys_timer .offset function pointer, and instead
directly set the arch_gettimeoffset function pointer when the timer
driver is initialized. This requires multiplying all function results
by 1000, since the removed arm_gettimeoffset() did this. Also,

Pull ARM SoC updates from Olof Johansson:
"This contains the bulk of new SoC development for this merge window.
Two new platforms have been added, the sunxi platforms (Allwinner A1x
SoCs) by Maxime Ripard, and a generic Broadcom platform for a new
series of ARMv7 platforms from them, where the hope is that we can
keep the platform code generic enough to have them all share one mach
directory. The new Broadcom platform is contributed by Christian
Daudt.
Highbank has grown support for Calxeda's next generation of hardware,
ECX-2000.
clps711x has seen a lot of cleanup from Alexander Shiyan, and he's
also taken on maintainership of the platform.
Beyond this there has been a bunch of work from a number of people on
converting more platforms to IRQ domains, pinctrl conversion, cleanup
and general feature enablement across most of the active platforms."
Fix up trivial conflicts as per Olof.

When using DEBUG_LL, the UART's (or other HW's) registers are mapped
into early page tables based on the results of assembly macro addruart.
Later, when the page tables are replaced, the same virtual address must
remain valid. Historically, this has been ensured by using defines from
<mach/iomap.h> in both the implementation of addruart, and the machine's
.map_io() function. However, with the move to single zImage, we wish to
remove <mach/iomap.h>. To enable this, the macro addruart may be used
when constructing the late page tables too; addruart is exposed as a
C function debug_ll_addr(), and used to set up the required mapping in
debug_ll_io_init(), which may called on an opt-in basis from a machine's
.map_io() function.

This adds a 'struct smp_operations' to abstract the CPU initialization
and hot plugging functions on SMP systems, which otherwise conflict
in a multiplatform kernel. This also helps shmobile and potentially
others that have more than one method to do these.
To allow the kernel to continue building, the platform hooks are
defined as weak symbols which are overrided by the platform code.
Once all platforms are converted, the "weak" attribute will be
removed and the function made static.
Unlike the original version from Marc, this new version from Arnd
does not use a generalized abstraction for per-soc data structures
but only tries to solve the problem for the SMP operations. This
way, we can collapse the previous four data structures into a
single struct, which is less systematic but also easier to follow
as a causal reader.

From Rob Herring <[email protected]>:
This is the 2nd part of mach/io.h removals. This series removes io.h on
platforms with PCI by creating a fixed virtual I/O mapping and a common
__io() macro.
This version has changed a bit to accommodate Tegra converting its PCIe
host to a platform driver. Now the virtual space is only reserved during
early boot before .map_io() is called. The mapping is not created until
calling pci_ioremap_io which can be done at any point after vmalloc is
initialized.
I've gone back to fixed 64K windows for each PCI bus. This allows
removing all the i/o resource setup from the individually platforms and
placing it within the common ARM PCI code.
I've only tested versatilepb under qemu (with the model hacked up to
actually enable i/o space), so any testing is appreciated. iop3xx and
mv78xx0 have some risk of breaking as the PCI bus addresses are moved
to 0 from matching the cpu host bus addesss.

ARM: iop3xx: use fixed PCI i/o mapping

With consolidation of the PCI i/o mappings, the i/o space is being
set to start at a PCI bus addr of 0x0 and fixed to 64K per bus. In
this case the core ARM PCI setup code can setup the i/o resource.
Currently, the resource is only setup if the platform did not setup
an i/o resource.

This adds a fixed virtual mapping for PCI i/o addresses. The mapping is
located at the last 2MB of vmalloc region (0xfee00000-0xff000000). 2MB
is used to align with PMD size, but IO_SPACE_LIMIT is 1MB. The space
is reserved after .map_io and can be mapped at any time later with
pci_ioremap_io. Platforms which need early i/o mapping (e.g. for vga
console) can call pci_map_io_early in their .map_io function.
This has changed completely from the 1st implementation which only
supported creating the static mapping at .map_io.

Pull CMA and ARM DMA-mapping updates from Marek Szyprowski:
"These patches contain two major updates for DMA mapping subsystem
(mainly for ARM architecture). First one is Contiguous Memory
Allocator (CMA) which makes it possible for device drivers to allocate
big contiguous chunks of memory after the system has booted.
The main difference from the similar frameworks is the fact that CMA
allows to transparently reuse the memory region reserved for the big
chunk allocation as a system memory, so no memory is wasted when no
big chunk is allocated. Once the alloc request is issued, the
framework migrates system pages to create space for the required big
chunk of physically contiguous memory.
For more information one can refer to nice LWN articles:
- 'A reworked contiguous memory allocator':
http://lwn.net/Articles/447405/
- 'CMA and ARM':
http://lwn.net/Articles/450286/
- 'A deep dive into CMA':
http://lwn.net/Articles/486301/
- and the following thread with the patches and links to all previous
versions:
https://lkml.org/lkml/2012/4/3/204
The main client for this new framework is ARM DMA-mapping subsystem.
The second part provides a complete redesign in ARM DMA-mapping
subsystem. The core implementation has been changed to use common
struct dma_map_ops based infrastructure with the recent updates for
new dma attributes merged in v3.4-rc2. This allows to use more than
one implementation of dma-mapping calls and change/select them on the
struct device basis. The first client of this new infractructure is
dmabounce implementation which has been completely cut out of the
core, common code.
The last patch of this redesign update introduces a new, experimental
implementation of dma-mapping calls on top of generic IOMMU framework.
This lets ARM sub-platform to transparently use IOMMU for DMA-mapping
calls if one provides required IOMMU hardware.
For more information please refer to the following thread:
http://www.spinics.net/lists/arm-kernel/msg175729.html
The last patch merges changes from both updates and provides a
resolution for the conflicts which cannot be avoided when patches have
been applied on the same files (mainly arch/arm/mm/dma-mapping.c)."

This patch adds support for CMA to dma-mapping subsystem for ARM
architecture. By default a global CMA area is used, but specific devices
are allowed to have their private memory areas if required (they can be
created with dma_declare_contiguous() function during board
initialisation).
Contiguous memory areas reserved for DMA are remapped with 2-level page
tables on boot. Once a buffer is requested, a low memory kernel mapping
is updated to to match requested memory access type.
GFP_ATOMIC allocations are performed from special pool which is created
early during boot. This way remapping page attributes is not needed on
allocation time.
CMA has been enabled unconditionally for ARMv6+ systems.

Most PCI implementations use the standard PCI swizzle function, which
handles the well defined behaviour of PCI-to-PCI bridges which can be
found on cards (eg, four port ethernet cards.)
Rather than having almost every platform specify the standard swizzle
function, make this the default when no swizzle function is supplied.
Therefore, a swizzle function only needs to be provided when there is
something exceptional which needs to be handled.
This gets rid of the swizzle initializer from 47 files, and leaves us
with just two platforms specifying a swizzle function: ARM Integrator
and Chalice CATS.

Some platforms mark their hw_pci structure as __initdata, which means
it will be discarded after init time. Storing pointers to __initdata
in long lived data structures is a potential source of problems, and
in this case, sys->hw is unused apart from its initialization.
So, lets remove this member and its initializer.

Convert from pci_scan_bus() to pci_scan_root_bus() and remove root bus
resource fixups. This fixes the problem of "early" and "header" quirks
seeing incorrect root bus resources.

This resolves the conflict in the arch/arm/mach-s3c64xx/s3c6400.c file,
and it fixes the build error in the arch/x86/kernel/microcode_core.c
file, that the merge did not catch.
The microcode_core.c patch was provided by Stephen Rothwell
<[email protected]> who was invaluable in the merge issues involved
with the large sysdev removal process in the driver-core tree.

After all sysdev classes are ported to regular driver core entities, the
sysdev implementation will be entirely removed from the kernel.

Fix up mostly pretty trivial conflicts in:
- arch/arm/Kconfig
- arch/arm/include/asm/localtimer.h
- arch/arm/kernel/Makefile
- arch/arm/mach-shmobile/board-ap4evb.c
- arch/arm/mach-u300/core.c
- arch/arm/mm/dma-mapping.c
- arch/arm/mm/proc-v7.S
- arch/arm/plat-omap/Kconfig
largely due to some CONFIG option renaming (ie CONFIG_PM_SLEEP ->
CONFIG_ARM_CPU_SUSPEND for the arm-specific suspend code etc) and
addition of NEED_MACH_MEMORY_H next to HAVE_IDE.

Get rid of the mdesc pointer in the fixup function call. No one uses
the mdesc pointer, it shouldn't be modified anyway, and we can't wrap
it, so let's remove it.
Platform files found by:
$ regexp=$(git grep -h '\.fixup.*=' arch/arm |
sed 's!.*= *\([^,]*\),* *!\1!' | sort -u |
tr '\n' '|' | sed 's,|$,,;s,|,\\|,g')
$ git grep $regexp arch/arm

On certain architectures, there might be a need to mark certain
addresses with strongly ordered memory attributes to avoid ordering
issues at the interconnect level.
On OMAP4, the asynchronous bridge buffers can only be drained
with strongly ordered accesses and hence the need to mark the
memory strongly ordered.

The boot_params member of the mdesc structure is used to provide a
default physical address for the ATAG list. Since this value is fixed
at compile time and sometimes based on constants such as ARCH_PHYS_OFFSET,
it gets in the way of runtime PHYS_OFFSET and CONFIG_ARM_PATCH_PHYS_VIRT
usage.
Let's introduce atag_offset which should contains only the relative
offset from PHYS_OFFSET instead of an absolute value, in preparation
to move all instance of boot_params over to it.

Aside of the usual motivation for constification, this function has a
history of being abused a hook for interrupt and other fixups so I turned
this function const ages ago in the MIPS code but it should be done
treewide.
Due to function pointer passing in varous places a few other functions
had to be constified as well.
