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.
Signed-off-by: Paul Mackerras <paulus@samba.org>
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.

The ADB keyboard, which is used for Apple PowerBooks, has strange behavior
with regard to the capslock key. It keeps track of capslock state
internally, and it sends a keycode when capslock is engaged and a keycode
when capslock is disengaged.
When the current adbhid driver sees that the capslock key is pressed or
released, it creates both a keypress event and a keyrelease event
simultaneously. This results in normal capslock behavior.
While this works, it makes it impossible to remap the capslock key to be a
control key. However, by translating the 0xff keycode into capslock
keycodes, we can restore the missing capslock events and make it possible
to remap the capslock key.
With this patch, the adbhid driver will translate these 0xff keycodes into
capslock keypresses and keyreleases if
/sys/module/adbhid/parameters/restore_capslock_events is set to 1.
Otherwise it will retain the current behavior. This option is off by
default because occasionally the 0xff keycode is not a capslock event, and
a mistake may require the user to tap the capslock key.

When a Fn key is used in combination with another key in ADB keyboards
it will generate a Fn event and then a second event that can be a
different key than pressed (Fn + F1 for instance can generate Fn +
brightness down if it's configured like that). This enables the
reporting of the Fn key to the input system.
As Fn is a dead key for most purposes, it's useful to report it so
applications can make use of it. One example is apple_mouse
(https://jake.ruivo.org/uinputd/trunk/apple_mouse/) that emulates the
second and third keys using a combination of keyboard keys and the mouse
button. Other applications may use the KEY_FN as a modifier as well.

Currently, the freezer treats all tasks as freezable, except for the kernel
threads that explicitly set the PF_NOFREEZE flag for themselves. This
approach is problematic, since it requires every kernel thread to either
set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't
care for the freezing of tasks at all.
It seems better to only require the kernel threads that want to or need to
be frozen to use some freezer-related code and to remove any
freezer-related code from the other (nonfreezable) kernel threads, which is
done in this patch.
The patch causes all kernel threads to be nonfreezable by default (ie. to
have PF_NOFREEZE set by default) and introduces the set_freezable()
function that should be called by the freezable kernel threads in order to
unset PF_NOFREEZE. It also makes all of the currently freezable kernel
threads call set_freezable(), so it shouldn't cause any (intentional)
change of behaviour to appear. Additionally, it updates documentation to
describe the freezing of tasks more accurately.

Let the drivers specify how many bytes they want to read with
i2c_smbus_read_i2c_block_data(). So far, the block count was
hard-coded to I2C_SMBUS_BLOCK_MAX (32), which did not make much sense.
Many driver authors complained about this before, and I believe it's
about time to fix it. Right now, authors have to do technically stupid
things, such as individual byte reads or full-fledged I2C messaging,
to work around the problem. We do not want to encourage that.
I even found that some bus drivers (e.g. i2c-amd8111) already
implemented I2C block read the "right" way, that is, they didn't
follow the old, broken standard. The fact that it was never noticed
before just shows how little i2c_smbus_read_i2c_block_data() was used,
which isn't that surprising given how broken its prototype was so far.
There are some obvious compatiblity considerations:
* This changes the i2c_smbus_read_i2c_block_data() prototype. Users
outside the kernel tree will notice at compilation time, and will
have to update their code.
* User-space has access to i2c_smbus_xfer() directly using i2c-dev, so
the changed expectations would affect tools such as i2cdump. In order
to preserve binary compatibility, we give I2C_SMBUS_I2C_BLOCK_DATA
a new numeric value, and define I2C_SMBUS_I2C_BLOCK_BROKEN with the
old numeric value. When i2c-dev receives a transaction with the
old value, it can convert it to the new format on the fly.

sysfs is now completely out of driver/module lifetime game. After
deletion, a sysfs node doesn't access anything outside sysfs proper,
so there's no reason to hold onto the attribute owners. Note that
often the wrong modules were accounted for as owners leading to
accessing removed modules.
This patch kills now unnecessary attribute->owner. Note that with
this change, userland holding a sysfs node does not prevent the
backing module from being unloaded.
