* Rename init_hwif_data() to ide_init_port_data() and export it.
* For all users of ide_register_hw() with 'initializing' argument set
hwif->present and hwif->hold are always zero so convert these host
drivers to use ide_find_port()+ide_init_port_data()+ide_init_port_hw()
instead (also no need for init_hwif_default() call since the setup
done by it gets over-ridden by ide_init_port_hw() call).
* Drop 'initializing' argument from ide_register_hw().

This fixes a few issues with via-pmu based backlight control.
First, it fixes a sign problem with the setup of the backlight
curve since the `range' value there -can- (and will) go negative.
Then, it reworks the interaction between this and the via-pmu sleep
code to properly restore backlight on wakeup from sleep.

These hooks ensure that a decrementer interrupt is not pending when
suspending; otherwise, problems may occur on 6xx/7xx/7xxx-based
systems (except for powermacs, which use a separate suspend path).
For example, with deep sleep on the 831x, a pending decrementer will
cause a system freeze because the SoC thinks the decrementer interrupt
would have woken the system, but the core must have interrupts
disabled due to the setup required for deep sleep.
Changed via-pmu.c to use the new ppc_md hooks, and made the arch_*
functions call the generic_* functions unconditionally. -- paulus

This adds platform_suspend_ops for PMU based machines, directly in
the PMU driver. This allows suspending via /sys/power/state
on powerbooks.
The patch also replaces the PMU ioctl with a simple call to
pm_suspend(PM_SUSPEND_MEM).
Additionally, it cleans up some debug code.

Sleep on the powerbook 3400 has been broken since the change that made
powerbook_sleep_3400 call pmac_suspend_devices(), which disables
interrupts. There are a couple of loops in powerbook_sleep_3400 that
depend on interrupts being enabled, and in fact it has to have
interrupts enabled at the point of going to sleep since it is an
interrupt from the PMU that wakes it up.
This fixes it by using pmu_wait_complete() instead of a spinloop, and
by explicitly enabling interrupts before putting the CPU into sleep
mode (which is OK since all interrupts except the PMU interrupt have
been disabled at the interrupt controller by this stage).
This changes the logic so that it keeps putting the CPU into sleep mode
until the completion of the interrupt transaction from the PMU that
signals the end of sleep. Also, we now call pmu_unlock() before sleep
so that the via_pmu_interrupt() code can process the interrupt event
from the PMU properly.
Now that generic code saves and restores PCI state, it is no longer
necessary to do that here. Thus pbook_pci_save/restore and related
functions are no longer necessary, so this removes them.
Lastly, this moves the ioremap of the memory controller to init code
rather than doing it on every sleep/wakeup cycle.

This converts the therm_pm72.c driver to use the kthread API. I
thought about making it use kthread_stop() instead of the `state'
variable and the `ctrl_complete' completion, but that isn't simple and
will require changing the way that `state' is used.

This converts adb.c to use the kthread API.
It also changes adb_request so that if the ADBREQ_SYNC flag is
specified, we now sleep waiting for the request to finish using an
on-stack completion rather than spinning. To implement this, we now
require that if the ADBREQ_SYNC flag is set, the `done' parameter must
be NULL. All of the existing callers of adb_request that pass
ADBREQ_SYNC appear to be in process context and have done == NULL.
Doing this allows us to get rid of an awful hack in adb_request()
where we used to test whether the request was coming from the adb
probe task and use a completion if it was, and otherwise spin.
This also gets rid of a static request block that was used if the req
parameter to adb_request was NULL. None of the callers do that any
more, so the static request block is no longer necessary.

When I fixed the windfarm freezer interaction first in commit
1ed2ddf380, an earlier patch than the one
I came up with after comments was committed. This has come back to haunt
us now because commit d5d8c5976d changed
the freezer to no long send signals. Fix it by removing the windfarm
thread's signal logic and restoring the original try_to_freeze().
We could simply revert 1ed2ddf380 now
but I feel that the assertion that no signal is delivered to the
windfarm thread needs not be there.
