drivers: base: use standard device online/offline for state change
There are two ways to set the online/offline state for a memory block:
echo 0|1 > online and echo online|online_kernel|online_movable|offline >
state.
The state attribute can online a memory block with extra data, the
"online type", where the online attribute uses a default online type of
ONLINE_KEEP, same as echo online > state.
Currently there is a state_mutex that provides consistency between the
memory block state and the underlying memory.
The problem is that this code does a lot of things that the common
device layer can do for us, such as the serialization of the
online/offline handlers using the device lock, setting the dev->offline
field, and calling kobject_uevent().
This patch refactors the online/offline code to allow the common
device_[online|offline] functions to be used. The result is a simpler
and more common code path for the two state setting mechanisms. It also
removes the state_mutex from the struct memory_block as the memory block
device lock provides the state consistency.
No functional change is intended by this patch.

23ca4bba3 (x86:
cleanup early per cpu variables/accesses v4) to indicate pointers to the

stack.
But later in commit
fbd59a8d (cpumask: Use topology_core_cpumask()/
topology_thread_cpumask()), the pointers to the topology struct cpumask maps

After that commit, the only difference is that there is a redundant
"unsigned int cpu = dev->id;" if arch_provides_topology_pointers defined, but
dev->id is type 'u32' which devolves to 'unsigned int' on all supported arches.

Revert "ACPI / video / i915: No ACPI backlight if firmware expects Windows 8"
We attempted to address a regression introduced by commit
a57f7f9
(ACPICA: Add Windows8/Server2012 string for _OSI method.) after which
ACPI video backlight support doesn't work on a number of systems,
because the relevant AML methods in the ACPI tables in their BIOSes
become useless after the BIOS has been told that the OS is compatible
with Windows 8. That problem is tracked by the bug entry at:
https://bugzilla.kernel.org/show_bug.cgi?id=51231
Commit
8c5bd7a (ACPI / video / i915: No ACPI backlight if firmware
expects Windows 8) introduced for this purpose essentially prevented
the ACPI backlight support from being used if the BIOS had been told
that the OS was compatible with Windows 8 and the i915 driver was
loaded, in which case the backlight would always be handled by i915.
Unfortunately, however, that turned out to cause problems with
backlight to appear on multiple systems with symptoms indicating that
i915 was unable to control the backlight on those systems as
expected.
For this reason, revert commit
8c5bd7a, but leave the function
acpi_video_backlight_quirks() introduced by it, because another
commit on top of it uses that function.

Commit
a82274151af "tracing: Protect ftrace_trace_arrays list in trace_events.c"
added taking the trace_types_lock mutex in trace_events.c as there were
several locations that needed it for protection. Unfortunately, it also
encapsulated a call to tracing_reset_all_online_cpus() which also takes
the trace_types_lock, causing a deadlock.
This happens when a module has tracepoints and has been traced. When the
module is removed, the trace events module notifier will grab the
trace_types_lock, do a bunch of clean ups, and also clears the buffer
by calling tracing_reset_all_online_cpus. This doesn't happen often
which explains why it wasn't caught right away.

Merge tag 'drm-intel-fixes-2013-07-25' of git://people.freedesktop.org/~danvet/drm-intel into drm-fixes
Brown-paper-bag pull request here. The snb rc6 fix from the last pull
broke forcewake BIOS dirt cleanup, which with fixed. But that fix broke
the spinlock init sequence, which results in an ugly BUG when spinlock
debugging is enabled :( So I get to throw another patch at cc: stable to
fix up the mess ...

mfd: max8925: fix dt code for backlight
The device-tree enablement for max8925 has several problems, but besides
the bindings being wrong (and not having seen review) there's also some
bad coding practices on how to fill in the platform_data from device tree.
I came across this since it causes a warning when compiling
mmp2_defconfig, and instead of doing the minimal fix to silence the
warning, I restructured the code a bit.
This silences the warning:
drivers/video/backlight/max8925_bl.c: In function 'max8925_backlight_probe':
drivers/video/backlight/max8925_bl.c:177:3: warning: statement with no effect [-Wunused-value]
Note that the bindings themselves need to be revisited too, but that will
affect more than just the backlight driver and is best done separately;
this just fixes the bad code for the backlight driver.

kobject: delayed kobject release: help find buggy drivers
Implement debugging for kobject release functions. kobjects are
reference counted, so the drop of the last reference to them is not
predictable. However, the common case is for the last reference to be
the kobject's removal from a subsystem, which results in the release
function being immediately called.
This can hide subtle bugs, which can occur when another thread holds a
reference to the kobject at the same time that a kobject is removed.
This results in the release method being delayed.
In order to make these kinds of problems more visible, the following
patch implements a delayed release; this has the effect that the
release function will be out of order with respect to the removal of
the kobject in the same manner that it would be if a reference was
being held.
This provides us with an easy way to allow driver writers to debug
their drivers and fix otherwise hidden problems.
