For platforms using device tree, the static keypad device instances
are not required and SAMSUNG_DEV_KEYPAD is not selected. Since,
samsung keypad driver has dependency on SAMSUNG_DEV_KEYPAD config
option, the driver is left out of the compilation for dt enabled
platforms.
An additional config option 'HAVE_SAMSUNG_KEYPAD' is added
which the device tree based platforms can select. This config
option is added as an alternative dependency for keypad driver.

ARM: EXYNOS4: Add a alias for pdma clocks
PDMA controllers when instantiated from device tree are registered using
amba_device_register(). The registration process enables clock to the
controllers to read the peripheral id of the PDMA amba device.
In case of Exynos4, the clocks to the PDMA controllers are named as 'dma'
but amba_device_register() looks up the clock using the name 'apb_pclk'.
Hence, alias clocks with name 'apb_pclk' clock are created for clocks
with name 'dma'.

DMA: PL330: Add device tree support
For PL330 dma controllers instantiated from device tree, the channel
lookup is based on phandle of the dma controller and dma request id
specified by the client node. During probe, the private data of each
channel of the controller is set to point to the device node of the
dma controller. The 'chan_id' of the each channel is used as the
dma request id.
Client driver requesting dma channels specify the phandle of the
dma controller and the request id. The pl330 filter function
converts the phandle to the device node pointer and matches that
with channel's private data. If a match is found, the request id
from the client node and the 'chan_id' of the channel is matched.
A channel is found if both the values match.

represented outside of the uart controller.
This patch creates a new clock by name "fclk_n" for s3c2440 based platforms to

callback that checks the UCON0/1/2 registers to determine the clock rate. The

sysfs: Make sysfs_rename safe with sysfs_dirents in rbtrees.
In sysfs_rename we need to remove the optimization of not calling
sysfs_unlink_sibling and sysfs_link_sibling if the renamed parent
directory is not changing. This optimization is no longer valid now
that sysfs dirents are stored in an rbtree sorted by name.
Move the assignment of s_ns before the call of sysfs_link_sibling. With
no sysfs_dirent fields changing after the call of sysfs_link_sibling
this allows sysfs_link_sibling to take any of the directory entries into
account when it builds the rbtrees, and s_ns looks like a prime canidate
to be used in the rbtree in the future.

Add extra arch overrides to asm-generic/checksum.h
There are plausible reasons for architectures to provide their own
versions of csum_partial_copy_nocheck and csum_tcpudp_magic.
By protecting these, the architecture can still re-use the
asm-generic checksum.h, instead of copying it.

epoll: fix spurious lockdep warnings
epoll can acquire recursively acquire ep->mtx on multiple "struct
eventpoll"s at once in the case where one epoll fd is monitoring another
epoll fd. This is perfectly OK, since we're careful about the lock
ordering, but it causes spurious lockdep warnings. Annotate the recursion
using mutex_lock_nested, and add a comment explaining the nesting rules
for good measure.
Recent versions of systemd are triggering this, and it can also be
demonstrated with the following trivial test program:
--------------------8<--------------------
int main(void) {
int e1, e2;
struct epoll_event evt = {
.events = EPOLLIN
};

checkpatch: add a --strict check for utf-8 in commit logs
Some find using utf-8 in commit logs inappropriate.
Some patch commit logs contain unintended utf-8 characters when doing
things like copy/pasting compilation output.
Look for the start of any commit log by skipping initial lines that look
like email headers and "From: " lines.
Stop looking for utf-8 at the first signature line.
