952184304f I/OAT: Add completion callback for async_tx interface use
The async_tx interface includes a completion callback.  This adds support

612b5a8d3a IPMI: new NMI handling
Convert over to the new NMI handling for getting IPMI watchdog timeouts via an
NMI.  This add config options to know if there is the ability to receive NMIs
and if it has an NMI post processing call.  Then it modifies the IPMI watchdog
to take advantage of this so that it can know if an NMI comes in.

It also adds testing that the IPMI NMI watchdog works.

fcfa472411 IPMI: add polled interface
Currently the IPMI watchdog timer sets the watchdog timeout on a panic, but it
doesn't actually poll the interface to make sure the message goes out.

Add an interface for polling the IPMI driver, and add code to the IPMI
watchdog timer to poll the interface when the timer is set from a panic.

f8fbcd3b9d IPMI: remove bogus semaphore from watchdog
Lockdep was giving an error when loading the IPMI watchdog module.  It turns
out that if you try to claim a lock in a parameter handling routine, lockdep
won't see that lock as "static" yet because the module is not yet on the
module list, so it will complain.

However, the semaphore in question is completely unnecessary.  So just remove
it.

c45adc3915 IPMI: don't init irq until ready
Patrick found a race at startup.  Interrupts were being enabled for the IPMI
interface before the driver was really ready to handle them.  This could
result in an oops if something was pending on the interface at startup and
interrupt were already enabled (technically shouldn't happen, but need to
cover for this in real life).  So move the IRQ setup to the code that starts
the actual IPMI processing.

So just kill the binary paths.

doesn't look like the parport code ever examines it, and it's bad sysctl form.

By previous cpu hotplug notifier change, we don't need to track topology_dev
existence for each cpu by topology_dev_map.

34c6538413 unify DMA_..BIT_MASK definitions: v3.1
Remove redundant DMA_..BIT_MASK definitions across two drivers.  The
computation of the majority of the bitmasks is done by the compiler.  The
initial split of the patch touching each a different file got removed due
to possible git bisect breakage.

c7e0831d38 Hibernation: Check if ACPI is enabled during restore in the right place
The following scenario leads to total confusion of the platform firmware on
some boxes (eg. HPC nx6325):
* Hibernate with ACPI enabled
* Resume passing "acpi=off" to the boot kernel

To prevent this from happening it's necessary to check if ACPI is enabled (and
enable it if that's not the case) _right_ _after_ control has been transfered
from the boot kernel to the image kernel, before device_power_up() is called
(ie.  with interrupts disabled).   Enabling ACPI after calling
device_power_up() turns out to be insufficient.

For this reason, introduce new hibernation callback ->leave() that will be
executed before device_power_up() by the restored image kernel.   To make it
work, it also is necessary to move swsusp_suspend() from swsusp.c to disk.c
(it's name is changed to "create_image", which is more up to the point).

8f4ce8c32f serial: turn serial console suspend a boot rather than compile time option
Currently, there's a CONFIG_DISABLE_CONSOLE_SUSPEND that allows one to stop
the serial console from being suspended when the rest of the machine goes
to sleep.  This is incredibly useful for debugging power management-related
things; however, having it as a compile-time option has proved to be
incredibly inconvenient for us (OLPC).  There are plenty of times that we
want serial console to not suspend, but for the most part we'd like serial
console to be suspended.

This drops CONFIG_DISABLE_CONSOLE_SUSPEND, and replaces it with a kernel
boot parameter (no_console_suspend).  By default, the serial console will
be suspended along with the rest of the system; by passing
'no_console_suspend' to the kernel during boot, serial console will remain
alive during suspend.

For now, this is pretty serial console specific; further fixes could be
applied to make this work for things like netconsole.

f059bca1c5 pm_trace displays the wrong time from the RTC
The way in which read_magic_time() displays the date read from the RTC is
apparently confusing to the users (cf.
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=250238).  Make it
print dates in the standard way.

e42837bcd3 freezer: introduce freezer-friendly waiting macros
Introduce freezer-friendly wrappers around wait_event_interruptible() and
wait_event_interruptible_timeout(), originally defined in <linux/wait.h>, to
be used in freezable kernel threads.  Make some of the freezable kernel
threads use them.

This is necessary for the freezer to stop sending signals to kernel threads,
which is implemented in the next patch.

74f270af0c PM: Rework struct hibernation_ops
During hibernation we also need to tell the ACPI core that we're going to put
the system into the S4 sleep state.  For this reason, an additional method in
'struct hibernation_ops' is needed, playing the role of set_target() in
'struct platform_suspend_operations'.  Moreover, the role of the .prepare()
method is now different, so it's better to introduce another method, that in
general may be different from .prepare(), that will be used to prepare the
platform for creating the hibernation image (.prepare() is used anyway to
notify the platform that we're going to enter the low power state after the
image has been saved).

e6c5eb9541 PM: Rework struct platform_suspend_ops
There is no reason why the .prepare() and .finish() methods in 'struct
platform_suspend_ops' should take any arguments, since architectures don't use
these methods' argument in any practically meaningful way (ie.  either the
target system sleep state is conveyed to the platform by .set_target(), or
there is only one suspend state supported and it is indicated to the PM core
by .valid(), or .prepare() and .finish() aren't defined at all).   There also
is no reason why .finish() should return any result.
