This makes return_address return correct value for ftrace feature.
unwind_frame does not update frame->lr but frame->pc for backtrace.
And, the initialization for data.addr was missing so that wrong value

Untested, but I wanted to post before the weekend.
I think the implementation is a bit nicer, and though we have a callback
to get the guest-to-userspace offset, it might be faster since I think
most cases will re-use the same mapping.
Feedback on API welcome!

probe routine could index into port[] with -ve index. The check in
arc_uart_init_one() was too late.
This came to light when trying to port driver to CONFIG_OF, where
bydefault of-core code sets -ve platform dev id and in absence of
DT serial aliases, driver would use the -ve index.

Hi,
As part of converting ARC Port to devicetree infrastructure, the following
series converts the arc-uart driver to DT.
* The first patch is a bug-fix which showed up in the process as DT based
platform devices by default have -ve id
* Next two prepare the driver for forthcoming DT changes.

This is in preparation for devicetree based probing, where earlyprintk
won't have access to DT serial aliases which the normal probe would
absolutely rely on.

As Michael mentioned, set affinity and select queue will not work very
well when CPU IDs are not consecutive, this can happen with hot unplug.
Fix this bug by traversal the online CPUs, and create a per cpu variable
to find the mapping from CPU to the preferable virtual-queue.

Add a cpu notifier to virtio-net, so that we can reset the

Convert dmaengine channel requests to use
dma_request_slave_channel_compat(). This supports the DT case of
platforms requiring channel selection from either the OMAP DMA or
the EDMA engine. AM33xx only boots from DT and is the only user
implementing EDMA so in the !DT case we can default to the OMA
The EDMA DMAC has a hardware limitation that prevents supporting
scatter gather lists with any number of segments. The DMA Engine
API reports the maximum number of segments a channel can support
via the optional dma_get_channel_caps() API. If the nr_segs
capability is present, the value is used to
Adds a dma_request_slave_channel_compat() wrapper which accepts
both the arguments from dma_request_channel() and
dma_request_slave_channel(). Based on whether the driver is
instantiated via DT, the appropriate channel request call will be
made.
This allows for a much cleaner migration of drivers
Move mach-davinci/dma.c to common/edma.c so it can be used
by OMAP (specifically AM33xx) as well. This just moves the
private EDMA API and enables it to build on OMAP.

Hi Kukjin,
Today's linux-next merge of the samsung tree got conflicts in
many files with the arm-soc tree.
I just dropped the samsung tree for today. Please have a look and try to
fix this mess up, thanks.

Hi Kukjin,
Today's linux-next merge of the samsung tree got a conflict in
arch/arm/plat-samsung/time.c between various commits from the arm-soc
tree and commit 0e4a0a6e970e ("ARM: SAMSUNG: Remove unused
plat-samsung/time.c") from the samsung tree.
The latter removes the file, so I did that.

the specific pid.

Hi all,
Today's linux-next merge of the arm-soc tree got a conflict in

6bb27d7349db ("ARM: delete struct sys_timer") from the arm-soc tree.
