sscanf("abc123a", "abc%d%n", &a, &n); /* works */
However, the scanf function in the kernel doesn't convert the %n in that

In commit 0fba3a1f39 (a very long time ago,
May 2006), I fixed a bug that caused powermacs to crash when you tried
entering standby/mem suspend states.
As I'm now getting more familiar with the suspend code I notice a few
more things:
1. we previously misunderstood what pm_ops is for, it isn't supposed to be
for doing platform dependent suspend/resume stuff that needs to be done
for suspend to disk (as we currently try to use it!), it is instead for
entering platform dependent suspend states ("standby", "mem").
2. due to the first point, we never properly save FPU and altivec states
when suspending to disk. It probably hasn't hurt yet because the process
that writes the "disk" to /sys/power/state uses neither and its context
is used.
This patch addresses these points as follows:
1. remove all pm_ops from powermac, powermac suspend to ram isn't currently
usable via /sys/power/state but is done via the PMU instead.
2. move the code responsible for storing FPU/altivec state into
save_processor_state and the set_context() call to restore_processor_state.
3. add a call to kernel_enable_spe()
It may look like there is some code removal missing but that is
actually because the new suspend.h file overrides the ppc/suspend.h
one which was previously used.

This patch series cleans up some misconceptions about pm_ops. Some users of
the pm_ops structure attempt to use it to stop the user from entering suspend
to disk, this, however, is not possible since the user can always use
"shutdown" in /sys/power/disk and then the pm_ops are never invoked. Also,
platforms that don't support suspend to disk simply should not allow
configuring SOFTWARE_SUSPEND (read the help text on it, it only selects
suspend to disk and nothing else, all the other stuff depends on PM).
The pm_ops structure is actually intended to provide a way to enter
platform-defined sleep states (currently supported states are "standby" and
"mem" (suspend to ram)) and additionally (if SOFTWARE_SUSPEND is configured)
allows a platform to support a platform specific way to enter low-power mode
once everything has been saved to disk. This is currently only used by ACPI
(S4).
This patch:
The pm_ops.pm_disk_mode is used in totally bogus ways since nobody really
seems to understand what it actually does.
This patch clarifies the pm_disk_mode description.
It also removes all the arm and sh users that think they can veto suspend to
disk via pm_ops; not so since the user can always do echo shutdown >
/sys/power/disk, they need to find a better way involving Kconfig or such.
ACPI is the only user left with a non-zero pm_disk_mode.
The patch also sets the default mode to shutdown again, but when a new pm_ops
is registered its pm_disk_mode is selected as default, that way the default
stays for ACPI where it is apparently required.

appletouch uses urb->transfer_dma after having freed the urb, this shows
up only if the system is compiled with slab debugging. This patch fixes
it by reordering the free calls.

Sometimes we simply want to turn off or on everything, and when recently a
warning was added when a certain platform function can't be called, this
triggered all the time in those cases. This patch shows the warning only if
the error was different from the function not existing.
The alternative would be to not even try calling the function when it
doesn't exist by first checking which exist and then only calling those that
do, but that adds complexity that isn't necessary.

This patch makes snd-powermac load when it can't bind the device right
away. That's the expected behaviour for hotplugging, but fixes an
important problem I was seeing with doing a modprobe snd-powermac with
a version that refuses loading on machines with layout-id: snd-powermac
would create a bunch of uevents and then refuse to load, the uevents
causing udev to reload it again, ad eternum.

The IRQ rework caused some hiccups here, in some cases we call
get_irq without a device node. This patch makes it catch that
case and return NO_IRQ when it happens, along with changing the
place where the irq is checked to check for NO_IRQ instead of -1.

This patch fixes the front-LED Kconfig issues I introduced while
creating it. Apparently having a dependency isn't enough to have the
select not evaluated or something like that.
The patch also changes the default configuration for pmac32 select the
default for the LED to be the IDE trigger. While I was at it, I
completely updated the defconfig and also added snd-aoa to it.

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.

This patch removes from snd-powermac the code that check for the layout-id
and instead adds code that makes it refuse loading when a layout-id property
is present, nothing that snd-aoa should be used.
It also removes the 'toonie' codec from snd-powermac which was only ever
used on the mac mini which has a layout-id property.

This large patch adds all of snd-aoa.
Consisting of many modules, it currently replaces snd-powermac
for all layout-id based machines and handles many more (for
example new powerbooks and powermacs with digital output that
previously couldn't be used at all).
It also has support for all layout-IDs that Apple has (judging
from their Info.plist file) but not all are tested.
The driver currently has 2 known regressions over snd-powermac:
* it doesn't handle powermac 7,2 and 7,3
* it doesn't have a DRC control on snapper-based machines
I will fix those during the 2.6.18 development cycle.
