Use the functions introduced in by the previous patch,
suspend_device_irqs(), resume_device_irqs() and check_wakeup_irqs(),
to rework the handling of interrupts during suspend (hibernation) and
resume. Namely, interrupts will only be disabled on the CPU right
before suspending sysdevs, while device drivers will be prevented
from receiving interrupts, with the help of the new helper function,
before their "late" suspend callbacks run (and analogously during
resume).In addition, since the device interrups are now disabled before the
CPU has turned all interrupts off and the CPU will ACK the interrupts
setting the IRQ_PENDING bit for them, check in sysdev_suspend() if
any wake-up interrupts are pending and abort suspend if that's the
case.Signed-off-by: Rafael J. Wysocki

Impact: module build fix
Fix:
ERROR: "sysdev_resume" [arch/x86/kernel/apm.ko] undefined!
ERROR: "sysdev_suspend" [arch/x86/kernel/apm.ko] undefined!As these APIs are now used by the APM driver, which can be built
as a module.Also fix a few extra (and inconsistent) newlines in comment blocks
preceding these functions.Signed-off-by: Ingo Molnar

This adds a new sysdev_ext_attribute that stores a pointer to the variable
it manages and some utility functions/macro to easily use them.Previously all users wrote custom macros to generate show/store
functions for each variable, with this it is possible to avoid
that in many cases.Signed-off-by: Andi Kleen

This allow to dynamically generate attributes and share show/store
functions between attributes. Right now most attributes are generated
by special macros and lots of duplicated code. With the attribute
passed it's instead possible to attach some data to the attribute
and then use that in shared low level functions to do different things.I need this for the dynamically generated bank attributes in the x86
machine check code, but it'll allow some further cleanups.I converted all users in tree to the new show/store prototype. It's a single
huge patch to avoid unbisectable sections.Runtime tested: x86-32, x86-64

The systdev_class_register() and sysdev_register() functions have
pr_debug() statements which are enabled when the user selects the
driver core debug. Both of these routines do not produce the
correct output, as they make assumptions about data which has not
been initialised.In sysdev_class_register() the code uses the kobject_name(&cls->kset.kobj)
at the start of the function, but this is not setup until later in the
same call. Change this to use cls->name which is passed in from the caller.The sysdev_register() function tries to get the name of the sysdev by
kobject_name(&sysdev->kobj), but that isn't setup until later in the same
function so change this message to use the name of the sysdev's class and
add another message once the name is initialised.Signed-off-by: Ben Dooks

I've just found how easy it is to accidentally register a sysdev_driver for
two different classes. When this happens, bad things happen as the
sysdev_driver structure keeps has the list entry for the driver
registration.The following patch makes a WARN_ON() if this happens, although I think
BUG_ON or returning -EAGAIN could also be valid responses to this.Signed-off-by: Ben Dooks

We don't need a "default" ktype for a kset. We should set this
explicitly every time for each kset. This change is needed so that we
can make ksets dynamic, and cleans up one of the odd, undocumented
assumption that the kset/kobject/ktype model has.This patch is based on a lot of help from Kay Sievers.

No one uses sysdev_drivers. Because no one calls sysdev_driver_register
with NULL class.And it is difficult to imagine that someone want to implement a global
sysdev driver which is called with all sys_device on any kind of
sysdev_class.So this patch removes global sysdev_drivers list and update comments
for this change.Signed-off-by: Akinobu Mita

I recently picked up my older work to remove unnecessary #includes of
sched.h, starting from a patch by Dave Jones to not include sched.h
from module.h. This reduces the number of indirect includes of sched.h
by ~300. Another ~400 pointless direct includes can be removed after
this disentangling (patch to follow later).
However, quite a few indirect includes need to be fixed up for this.In order to feed the patches through -mm with as little disturbance as
possible, I've split out the fixes I accumulated up to now (complete for
i386 and x86_64, more archs to follow later) and post them before the real
patch. This way this large part of the patch is kept simple with only
adding #includes, and all hunks are independent of each other. So if any
hunk rejects or gets in the way of other patches, just drop it. My scripts
will pick it up again in the next round.Signed-off-by: Tim Schmielau

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!
