Hi,
lockdep support for seqlock was discussed at:
http://marc.info/?l=linux-kernel&m=137875860600648&w=2
This is very draft patch to add lockdep support for seqlock.
Actually, it doesn't work yet. I throw it out to get comments and help.

dst_addr_width and src_addr_width should be a power of 2. Currently the
driver checks, that they both lie between 1 and 8 and that they are eqal
to 1 or even. This however leaves an invalid value of 6 uncaught. Use an
explicit power of 2 check instead.

The drm/i915 gpu driver loves to hang onto as much memory as it can -
we cache pinned pages, dma mappings and obviously also gpu address
space bindings of buffer objects. On top of that userspace has its own
opportunistic cache which is managed by an madvise-like ioctl to tell

Adds support for thermal sensors on STiH41x series SOCs.
Single trip point 'THERMAL_TRIP_CRITICAL' is supported.
STIH416 MPE sensor supports interrupt reporting when a preset
threshold temperature is crossed.
For rest of the thermal sensors a polling delay of 1ms is
set.

Hello,
This is a second version of set of patches fixing s3c-hsotg USB driver
functioning. I've fixed issuses pointed by Felipe Balbi. For more information,
please check the change log at the end of the mail.
These patches add few fixes:
- Fix "protocol stall" handling, by enqueue new ep0 request
After normal handling of SetupDone interrupt, XferCompl interrupt occurs, and
then we enqueue new setup request. But when ep0 is stalled, there is no
XferCompl, so we have to enqueue setup request immediately after stalling ep.
Otherwise incoming control requests won't be processed correctly.

In s3c_hsotg_write_fifo function PTxFEmp/NPTxFEmp interrupts are enabled
only in shared-fifo mode. In dedicated-fifo mode they should not be used
(when enabled then cause interrupt storm).

When s3c_hsotg_trytx is called for ep without enqueued request, interrupts
for this ep are disabled, to prevent interrupt flooding. Interrupts are
enabled when new request for this ep is starting.

In OEPInt/IEPInt interrupts handling added bitwise and of DAINT and
DAINTMSK, because we should handle masked interrupts only.

Hi Kernel hackers,
I am trying to run Linux on Qemu/arm emulator with machine type
spitz. In the past this worked fine.
Now with Linux version 3.9.11 it does not boot anymore.
(blank screen, no kernel messages)
I used git bisect to find the commit, which breaks the boot:

Well, you should. Since commit 81e49f shrinker->count_objects might be
set

Hi Olof/Kevin,
I am reposting this series as suggested by Olof[1]. This is reviewed and
acked by Will and Catalin. Daniel needs Ack from arm-soc maintainers
to take these through his tree. Can you review this ?

The ARM architected timer can generate events (used for waking up
CPUs executing the wfe instruction) at a frequency represented as a
power-of-2 divisor of the clock rate.
An event stream might be used:
- To implement wfe-based timeouts for userspace locking implementations.

This patch adds support for configuring the event stream frequency
and enabling it.
It also adds the hwcaps as well as compat-specific definitions to
the user to detect this event stream feature.

Add macros to describe the bitfields in the ARM architected timer

Few control settings done in architected timer as part of initialisation
can be lost when CPU enters deeper power states. They need to be
restored when the CPU is (warm)reset again.

Previously the driver had only one-shot reading functionality.
This patch adds continuous sampling support to the driver.
Continuous sampling starts when buffer is enabled.
HW IRQ wakes worker thread that pushes samples to userspace.
Sampling stops when buffer is disabled by userspace.

Enable shared IRQ to allow ADC to share IRQ line from
parent MFD core. Only FIFO0 IRQs are for TSC and handled
on the TSC side.
Step mask would be updated from cached variable only previously.
In rare cases when both TSC and ADC are used, the cached
variable gets mixed up.
The step mask is written

Hi,
These apply to togreg branch in iio.
Round 10 updates
- Removed devm_free as not needed
Round 9 updates
- Removed Trigger.
- Restructured everything for INDIO_BUFFERED_HARDWARE mode.
- Threaded IRQ with top/bottom halfs. Top half HW IRQ wakes
bottom half threaded worker that pushes samples
