A pointer to wm8400_regulator_probe is passed to the core via
platform_driver_register and so the function must not disappear when the
.init sections are discarded. Otherwise (if also having HOTPLUG=y)
unbinding and binding a device to the driver via sysfs will result in an
oops as does a device being registered late.
An alternative to this patch is using platform_driver_probe instead of
platform_driver_register plus removing the pointer to the probe function
from the struct platform_driver.

ehca_plpar_hcall9() takes an unsigned long array, so make all callers
pass that in. This fixes warnings introduced by commit fe333321
("powerpc: Change u64/s64 to a long long integer type"), which changed
u64 from unsigned long to unsigned long long.

Commit fe333321 ("powerpc: Change u64/s64 to a long long integer
type") changed u64 from unsigned long to unsigned long long, which
means that printk formats for printing u64 values should use "ll"
instead of "l" to avoid warnings. Fix all the places affected by this
in ehca.

When IPoIB tries to join a multicast group, and the SA module's SM
address handle is NULL (because of an SM change, etc), the join
returns with -EAGAIN status. In that case, don't print an error
message unless multicast debugging is enabled.

The current work request posting code writes the LSO segment before
writing any data segments. This leaves a window where the LSO segment
overwrites the stamping in one cacheline that the HCA prefetches
before the rest of the cacheline is filled with the correct data
segments. When the HCA processes this work request, a local
protection error may result.
Fix this by saving the LSO header size field off and writing it only
after all data segments are written. This fix is a cleaned-up version
of a patch from Jack Morgenstein <jackm@dev.mellanox.co.il>.
This fixes <https://bugs.openfabrics.org/show_bug.cgi?id=1383>.

Although rfkill support for the EEE bluetooth device has been added to
2.6.28-rc the appropriate ACPI accessor definitions were not added, so
the support was non functional. The patch below adds the get and set
accessors and has been verified to work on an EEE 901.

Check CONFIG_FREEZER instead of CONFIG_PM because kprobe booster
depends on freeze_processes() and thaw_processes() when CONFIG_PREEMPT=y.
This fixes a linkage error which occurs when CONFIG_PREEMPT=y, CONFIG_PM=y

* git://git.kernel.org/pub/scm/linux/kernel/git/mason/btrfs-unstable:
Btrfs: fix ioctl arg size (userland incompatible change!)
Btrfs: Clear the device->running_pending flag before bailing on congestion
The structure used to send device in btrfs ioctl calls was not
properly aligned, and so 32 bit ioctls would not work properly on
64 bit kernels.
We could fix this with compat ioctls, but we're just one byte away
and it doesn't make sense at this stage to carry about the compat ioctls
forever at this stage in the project.
This patch brings the ioctl arg up to an evenly aligned 4k.

Btrfs maintains a queue of async bio submissions so the checksumming
threads don't have to wait on get_request_wait. In order to avoid
extra wakeups, this code has a running_pending flag that is used
to tell new submissions they don't need to wake the thread.
When the threads notice congestion on a single device, they
may decide to requeue the job and move on to other devices. This
makes sure the running_pending flag is cleared before the
job is requeued.
It should help avoid IO stalls by making sure the task is woken up
when new submissions come in.
