Small driver suspend() fixes in preparation for the PRETHAW events:

 - Only compare message events for equality against PM_EVENT_* codes;
   not against integers, or using greater/less-than comparisons.
   (PM_EVENT_* should really become a __bitwise thing.)

 - Explicitly test for SUSPEND events (rather than not-something-else)
   before suspending devices.

 - Removes more of the confusion between a pm_message_t (wraps event code)
   and a "state" ... suspend() originally took a target system state.

These updates are correct and appropriate even without new PM_EVENT codes.

Now that get_property() returns a void *, there's no need to cast its
return value. Also, treat the return value as const, so we can
constify get_property later.

This patch removes the old pmac ide led blink code and
adds generic LED subsystem support for the LED.

It maintains backward compatibility with the old
BLK_DEV_IDE_PMAC_BLINK Kconfig option which now
simply selects the new code and influences the
default trigger.

It looks like the generic ide code now wants ide_init_hwif_ports() to set
the parent struct device into the ide_hw structure (new field ?).  Without
this, the mac ide code can cause the ide probing code to explode in flames
in sysfs registration due to what looks like a stale pointer in there
(happens when removing/re-inserting one of the hotswap media bays on some
laptops).

This removes statically assigned platform numbers and reworks the
powerpc platform probe code to use a better mechanism.  With this,
board support files can simply declare a new machine type with a
macro, and implement a probe() function that uses the flattened
device-tree to detect if they apply for a given machine.

We now have a machine_is() macro that replaces the comparisons of
_machine with the various PLATFORM_* constants.  This commit also
changes various drivers to use the new macro instead of looking at
_machine.

This adds some very basic support for the new machines, including the
Quad G5 (tested), and other new dual core based machines and iMac G5
iSight (untested). This is still experimental !  There is no thermal
control yet, there is no proper handing of MSIs, etc.. but it
boots, I have all 4 cores up on my machine. Compared to the previous
version of this patch, this one adds DART IOMMU support for the U4
chipset and thus should work fine on setups with more than 2Gb of RAM.

The pre-parsed addrs/n_addrs fields in struct device_node are finally
gone. Remove the dodgy heuristics that did that parsing at boot and
remove the fields themselves since we now have a good replacement with
the new OF parsing code. This patch also fixes a bunch of drivers to use
the new code instead, so that at least pmac32, pseries, iseries and g5
defconfigs build.

Cleaning up the hwif without knowing its previous state in pmac.c is a big
and potentially dangerous job, and there seems to be no generic code interface
that would provide either a way to properly release an hwif or to clean it up.

Fixes OOPS for empty PMAC interface and add-on PCI controller.

This adds type-checking to pm_message_t, so that people can't confuse it
with int or u32.  It also allows us to fix "disk yoyo" during suspend (disk

This converts the usage of struct of_match to struct of_device_id,
similar to pci_device_id.  This allows a device table to be generated,
which can be parsed by depmod(8) to generate a map file for module
loading.

In order for hotplug to work with macio devices, patches to
module-init-tools and hotplug must be applied.  Those patches are

split into CONFIG_PMAC_MEDIABAY for the actual hotswap bay that some

out of any CONFIG_* option for some generally useful stuff that can be used
on non-laptops as well.

I noticed an occasional crash on wakeup from sleep on my powerbook
(strangly never happened before, probably timing related) that appears to
be due to a dangling interrupt while the chip is put to sleep and beeing
reset on wakeup.

This patch fixes is by disabling the irq in the ide pmac driver while
asleep and only re-enable it after the chip has been fully reset.  This is
safe to do so as the interrupt of these apple IDE cells is never shared.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
