and information reporting on the console.  This driver is required
by platforms that boot a zImage and use the MPSC for the console.

The mv64x60 host bridge has many windows between its various components
(cpu, system memory, ethernet ctlr, MPSC, DMA ctlr, PCI MEM, PCI I/O).
Unfortunately, the firmware on some of mv64x60-based platforms do not
properly or completely configure those windows (e.g., MPSC->system memory
windows not configured or CPU->PCI MEM space not configured).

So, the missing configuration needs to be done in either the bootwrapper
or in the kernel.  To keep the kernel as clean as possible, it is done
in the bootwrapper.  Note that I/O controller configuration is NOT being
done, its only the windows to allow the I/O controllers and other components
to access memory, etc. that is being done--drivers assume that their
controllers can already access system memory).

Table of routines and the windows they configure:
	mv64x60_config_ctlr_windows()	ENET->System Memory
					MPSC->System Memory
					IDMA->System Memory

	mv64x60_config_pci_windows()	PCI MEM->System Memory
					PCI I/O->Bridge's Registers

	mv64x60_config_cpu2pci_window()	CPU->PCI MEM
					CPU->PCI I/O

Add 'zImage.dts' and 'zImage.dts_initrd' build rules that automatically
compile and wrap a dts file from arch/powerpc/boot/dts into the zImage file.
The resulting zImage will be arch/powerpc/boot/zImage.dts.<platform> and
arch/powerpc/boot/zImage.dts_initrd.<platform>, respectively.

Having separate rules allows the user to choose whether to include a device
tree--and which device tree--at build time.  This is useful when one Makefile
target builds a zImage that runs on several platforms except for differing
device trees.  By just setting CONFIG_DEVICE_TREE and running "make zImage.dts"
the exact zImage you want is built without Makefile bloat or manually running
the wrapper script.

The dts file is expected to be arch/powerpc/boot/dts/$(CONFIG_DEVICE_TREE)

Greatly simplify the function smp_space_timers.

The stolen time calculation (per comment within the code) doesn't need the
half-jiffy stagger any more.  There isn't an issue with bouncing off global
locks, so we really shouldn't need any sort of staggering at all.

However, the last_jiffy value still needs to be set.   This removes the
extra stagger logic, and just sets the values.

This change should benefit applications that rely on barrier
synchronization, and will help cut down OS jitter.

This patch renames the raw hard_irq_{enable,disable} into
__hard_irq_{enable,disable} and introduces a higher level hard_irq_disable()
function that can be used by any code to enforce that IRQs are fully disabled,
not only lazy disabled.

The difference with the __ versions is that it will update some per-processor
fields so that the kernel keeps track and properly re-enables them in the next
local_irq_disable();

This prepares powerpc for my next patch that introduces hard_irq_disable()
generically.

My patch "Cope with PCI host bridge I/O window not starting at 0"
introduced a bug in the calculation of the virtual addresses for the
I/O windows of PCI host bridges other than the first, because it
didn't account for the fact that hose->io_resource gets offset so that
it reflects the range of global I/O port numbers assigned to the
bridge.  This fixes it and simplifies get_bus_io_range() in the
process.

non-zero.

The rheap allocation functions return a pointer, but the actual value is based
on how the heap was initialized, and so it can be anything, e.g. an offset
into a buffer.  A ulong is a better representation of the value returned by
the allocation functions.

This patch changes all of the relevant rheap functions to use a unsigned long
integers instead of a pointer.  In case of an error, the value returned is
a negative error code that has been cast to an unsigned long.  The caller can
use the IS_ERR_VALUE() macro to check for this.

All code which calls the rheap functions is updated accordingly.  Macros
IS_MURAM_ERR() and IS_DPERR(), have been deleted in favor of IS_ERR_VALUE().

Also added error checking to rh_attach_region().

This finally renames the thread_info field in task structure to stack, so that
the assumptions about this field are gone and archs have more freedom about
placing the thread_info structure.

Nonbroken archs which have a proper thread pointer can do the access to both

Since nonboot CPUs are now disabled after tasks and devices have been
frozen and the CPU hotplug infrastructure is used for this purpose, we need
special CPU hotplug notifications that will help the CPU-hotplug-aware
subsystems distinguish normal CPU hotplug events from CPU hotplug events
related to a system-wide suspend or resume operation in progress.  This
patch introduces such notifications and causes them to be used during
suspend and resume transitions.  It also changes all of the
CPU-hotplug-aware subsystems to take these notifications into consideration
(for now they are handled in the same way as the corresponding "normal"
ones).
