While waking up CPU from off state using clock domain force wakeup, restore
the CPU power state to ON state before putting CPU clock domain under
hardware control. Otherwise CPU wakeup might fail. The change is recommended
for all OMAP4+ devices though the PRCM weakness was observed on OMAP5

machine of local CPU PRCM and results are UN-predictable as per designers.

gets frozen. With power domain state restored, system behaves correctly.

clk: allow reentrant calls into the clk framework
Reentrancy into the clock framework is necessary for clock operations
that result in nested calls to the clk api. A common example is a clock
that is prepared via an i2c transaction, such as a clock inside of a
discrete audio chip or a power management IC. The i2c subsystem itself
will use the clk api resulting in a deadlock:
The ability to reenter the clock framework prevents this deadlock.
Other use cases exist such as allowing .set_rate callbacks to call
clk_set_parent to achieve the best rate, or to save power in certain
configurations. Yet another example is performing pinctrl operations
from a clk_ops callback. Calls into the pinctrl subsystem may call
clk_{un}prepare on an unrelated clock. Allowing for nested calls to
reenter the clock framework enables both of these use cases.
Reentrancy is implemented by two global pointers that track the owner
currently holding a global lock. One pointer tracks the owner during
sleepable, mutex-protected operations and the other one tracks the owner
during non-interruptible, spinlock-protected operations.
When the clk framework is entered we try to hold the global lock. If it
is held we compare the current task against the current owner; a match
implies a nested call and we reenter. If the values do not match then
we block on the lock until it is released.

Pull SCSI target fixes from Nicholas Bellinger:
"This includes the bug-fix for a >= v3.8-rc1 regression specific to
iscsi-target persistent reservation conflict handling (CC'ed to
stable), and a tcm_vhost patch to drop VIRTIO_RING_F_EVENT_IDX usage
so that in-flight qemu vhost-scsi-pci device code can detect the
proper vhost feature bits.
Also, there are two more tcm_vhost patches still being discussed by
MST and Asias for v3.9 that will be required for the in-flight qemu
vhost-scsi-pci device patch to function properly, and that should
(hopefully) be the last target fixes for this round."

dw_dmac: adjust slave_id accordingly to request line base
On some hardware configurations we have got the request line with the offset.
The patch introduces convert_slave_id() helper for that cases. The request line
base is came from the driver data provided by the platform_device_id table.

dmaengine: dw_dma: fix endianess for DT xlate function
As reported by Wu Fengguang's build robot tracking sparse warnings, the
dma_spec arguments in the dw_dma_xlate are already byte swapped on
little-endian platforms and must not get swapped again. This code is
currently not used anywhere, but will be used in Linux 3.10 when the
ARM SPEAr platform starts using the generic DMA DT binding.
The Adam Belay's e-mail address in MAINTAINERS under PNP SUPPORT
is not valid any more and I started to maintain that code in the
meantime as a matter of fact, so list myself as a maintainer of it
along with Bjorn and remove the Adam's entry from it.

rbd: don't zero-fill non-image object requests
A result of ENOENT from a read request for an object that's part of
an rbd image indicates that there is a hole in that portion of the
image. Similarly, a short read for such an object indicates that
the remainder of the read should be interpreted a full read with
zeros filling out the end of the request.
This behavior is not correct for objects that are not backing rbd
image data. Currently rbd_img_obj_request_callback() assumes it
should be done for all objects.
Change rbd_img_obj_request_callback() so it only does this zeroing
for image objects. Encapsulate that special handling in its own
function. Add an assertion that the image object request is a bio
request, since we assume that (and we currently don't support any
other types).
This resolves a problem identified here:

Pull btrfs fixes from Chris Mason:
"We've had a busy two weeks of bug fixing. The biggest patches in here
are some long standing early-enospc problems (Josef) and a very old
race where compression and mmap combine forces to lose writes (me).
I'm fairly sure the mmap bug goes all the way back to the introduction
of the compression code, which is proof that fsx doesn't trigger every
possible mmap corner after all.
I'm sure you'll notice one of these is from this morning, it's a small
and isolated use-after-free fix in our scrub error reporting. I
double checked it here."
