device_create_groups lets callers create devices as well as associated
sysfs attributes with a single call. This avoids race conditions seen
if sysfs attributes on new devices are created later.

This patch fixes improper in_pressure_scale output that is
returned by the lps331ap barometer sensor driver. According
to the documentation the pressure after applying the scale has to
be expressed in kilopascal units. With erroneous implementation
the scale value larger by two orders of magnitude is returned -
2441410 instead of 24414.

Fix a warning from lockdep caused by calling flush_work() for

The __cpuinit type of throwaway sections might have made sense
some time ago when RAM was more constrained, but now the savings
do not offset the cost and complications. For example, the fix in
commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time")
is a good example of the nasty type of bugs that can be created
with improper use of the various __init prefixes.
After a discussion on LKML[1] it was decided that cpuinit should go
the way of devinit and be phased out. Once all the users are gone,
we can then finally remove the macros themselves from linux/init.h.
This removes all the remaining one-off uses of the __cpuinit macros
from all C files in the drivers/* directory.

commit a66b2e (cpufreq: Preserve sysfs files across suspend/resume)
has unfortunately caused several things in the cpufreq subsystem to
break subtly after a suspend/resume cycle.
The intention of that patch was to retain the file permissions of the
cpufreq related sysfs files across suspend/resume. To achieve that,
the commit completely removed the calls to cpufreq_add_dev() and
__cpufreq_remove_dev() during suspend/resume transitions. But the
problem is that those functions do 2 kinds of things:
1. Low-level initialization/tear-down that are critical to the
correct functioning of cpufreq-core.
2. Kobject and sysfs related initialization/teardown.
Ideally we should have reorganized the code to cleanly separate these
two responsibilities, and skipped only the sysfs related parts during
suspend/resume. Since we skipped the entire callbacks instead (which
also included some CPU and cpufreq-specific critical components),
cpufreq subsystem started behaving erratically after suspend/resume.
So revert the commit to fix the regression. We'll revisit and address
the original goal of that commit separately, since it involves quite a
bit of careful code reorganization and appears to be non-trivial.
(While reverting the commit, note that another commit f51e1eb
(cpufreq: Fix cpufreq regression after suspend/resume) already
reverted part of the original set of changes. So revert only the
remaining ones).

device->driver_data needs to be cleared when releasing its data,
mem_device, in an error path of acpi_memory_device_add().
The function evaluates the _CRS of memory device objects, and fails
when it gets an unexpected resource or cannot allocate memory. A
kernel crash or data corruption may occur when the kernel accesses
the stale pointer.

An ACPI_NOTIFY_BUS_CHECK notification means that we should scan the
entire namespace starting from the given handle even if the device
represented by that handle is present (other devices below it may
just have appeared).
For this reason, modify acpi_scan_bus_device_check() to always run
acpi_bus_scan() if the notification being handled is of type
ACPI_NOTIFY_BUS_CHECK.

In acpi_bus_device_attach(), if there is an ACPI device object
for the given handle and that device object has a scan handler
attached to it already, there's nothing more to do for that handle.
Moreover, if acpi_scan_attach_handler() is called then, it may
execute the .attach() callback of the ACPI scan handler already
attached to the device object and that may lead to interesting
breakage.
For this reason, make acpi_bus_device_attach() return success
immediately when the handle's device object has a scan handler
attached to it.

They still seem to cause instability on some r6xx parts.
As a follow up, we can switch to using CP DMA for bo
moves on r6xx as a lighter weight alternative to using
the 3D engine.
A version of this patch should also go to stable kernels.
