This patch fixes the build break introduced by 3e1e4a5f. The mentioned
commit id makes the changes in file "include/linux/mfd/samsung/core.h"
by changing the members of structure sec_pmic_dev.
The patch replaces "regmap" with "regmap_pmic" because structure
sec_pmic_dev no more contains any member

This patch adds "biu" and "ciu" clocks for exynos4412 dwmmc
node. Without this patch, dwmmc host driver will skip enabling the
two clocks and it will break dwmmc host function on exynos4412.

Hello,
Following the fix I submitted a few weeks ago, here is a set of
patches that add USB support for the Ingenic JZ4740 MIPS SoC.
The JZ4740 is found in the Ben NanoNote handheld computer which is
built by the Qi-Hardware community.
Even though Ben NanoNote is already supported in the kernel,
JZ4740 USB Device Controller is not OTG compatible and does not have DEVCTL
register in silicon.
During ethernet-over-usb transactions, on reset, musb driver tries to
read from DEVCTL and consequently sets device as host (A-Device)
instead of peripheral (B-Device), which makes it a composite devic

To make the layout of 'struct page' look nicer, I broke
up a few of the unions. But, this has a cost: things that

This makes it *MUCH* more
SLUB depends on a 16-byte cmpxchg for an optimization. In order

Those 8-bytes matter. We've gone to great lengths to keep

why they are dumping the pag
In order to simplify 'struct page', we will shortly be moving
some fields around. This causes slub's ->freelist usage to
impinge on page->mapping's storage space. The buddy allocator
wants ->mapping to be NULL when a page is handed back, so we have
to make sure that it is cleared.
Note that sla
I added a bunch of longer than 80 column lines and other various

The descriptor unmapping code introduced in commit
d38a8c622a1b3 "dmaengine: prepare for generic 'unmap' data"
accidentally affects a local struct rather than the
async TX descriptor, resulting in this compile error:

This patch adds user_atomic_cmpxchg_inatomic() to use CMPXCHG
instruction against a user space address.
This generalizes the already existing futex_atomic_cmpxchg_inatomic()
so it can be used in other contexts. This will be used in the
upcoming support for Intel MPX (Memory Protection Extensions.
futex_atomic_cmpxchg_inatomic() is only the 32bit implementation of
user_atomic_cmpxchg_inatomic(). This patch replaces it with
user_atomic_cmpxchg_inatomic().

Hi Ariel.
I wrote a little checkpatch script to look for missing
switch/case breaks.
http://www.kernelhub.org/?msg=379933&p=2
There are _many_ instances of case blocks in sriov.c
that could be missing breaks as they use fall-throughs.
It would be good if these are actually intended to be

If rx->conn is not NULL, rxrpc_connect_exclusive() does not
acquire the transport's client lock, but it still releases it.
The patch adds locking of the spinlock to this path.

Hi Tejun.
Thanks for your work on this.
In your first email, in the first substantial paragraph (starting "Now,
if the rest.."), you say "libata device removal waits for the scheduled
writeback work item to finish". I wonder if that's the lynchpin. If we
know the device is gone, why are we tr
