The OMAP ASoC McBSP code implemented CLKR and FSR signal muxing via
direct System Control Module writes on OMAP2+. This required the
omap_ctrl_{read,write}l() functions to be exported, which is against
policy: the only code that should call those functions directly is
OMAP core code, not device drivers. omap_ctrl_{read,write}*() are no
longer exported, so the driver no longer builds as a module.
Fix the pinmuxing part of the problem by removing calls to
omap_ctrl_{read,write}l() from the OMAP ASoC McBSP code and
implementing signal muxing functions in arch/arm/mach-omap2/mcbsp.c.
Due to the unfortunate way that McBSP support is implemented in ASoC
and the OMAP tree, these symbols must be exported for use by
sound/soc/omap/omap-mcbsp.c.
Going forward, the McBSP device driver should be moved from
arch/arm/*omap* into drivers/ or sound/soc/*, and the CPU DAI driver
should be implemented as a platform_driver as many other ASoC CPU DAI
drivers are. These two steps should resolve many of the layering
problems, which will rapidly reappear during a McBSP hwmod/PM runtime
conversion.

The OMAP3 clock tree already contains the infrastructure to support

sys_semctl: fix kernel stack leakage
The semctl syscall has several code paths that lead to the leakage of
uninitialized kernel stack memory (namely the IPC_INFO, SEM_INFO,
IPC_STAT, and SEM_STAT commands) during the use of the older, obsolete
version of the semid_ds struct.
The copy_semid_to_user() function declares a semid_ds struct on the stack
and copies it back to the user without initializing or zeroing the
"sem_base", "sem_pending", "sem_pending_last", and "undo" pointers,
allowing the leakage of 16 bytes of kernel stack memory.
The code is still reachable on 32-bit systems - when calling semctl()

kfifo: fix scatterlist usage
The kfifo_dma family of functions use sg_mark_end() on the last element in
their scatterlist. This forces use of a fresh scatterlist for each DMA
operation, which makes recycling a single scatterlist impossible.
Change the behavior of the kfifo_dma functions to match the usage of the
dma_map_sg function. This means that users must respect the returned
nents value. The sample code is updated to reflect the change.
This bug is trivial to cause: call kfifo_dma_in_prepare() such that it
prepares a scatterlist with a single entry comprising the whole fifo.
This is the case when you map the entirety of a newly created empty fifo.
This causes the setup_sgl() function to mark the first scatterlist entry
as the end of the chain, no matter what comes after it.
Afterwards, add and remove some data from the fifo such that another call
to kfifo_dma_in_prepare() will create two scatterlist entries. It returns
nents=2. However, due to the previous sg_mark_end() call, sg_is_last()
will now return true for the first scatterlist element. This causes the
sample code to print a single scatterlist element when it should print
two.
By removing the call to sg_mark_end(), we make the API as similar as
possible to the DMA mapping API. All users are required to respect the
returned nents.

As noted by Michał Mirosław <mirqus@gmail.com>, the voltages should

As all these boards are using a GPIO to enable the power, chances
are that only 3.3V cards are supported on these boards.

Fix up more fallout form alpha signal cleanups
Commit
c52c2ddc1dfa ("alpha: switch osf_sigprocmask() to use of
sigprocmask()") had several problems. The more obvious compile issues
got fixed in commit
0f44fbd297e1 ("alpha: fix compile problem in
arch/alpha/kernel/signal.c"), but it also caused a regression.
Since _BLOCKABLE is already the set of signals that can be blocked, the
code should do "newmask & _BLOCKABLE" rather than inverting _BLOCKABLE
before masking.

ocfs2 fast symlinks are NUL terminated strings stored inline in the

theory, remove that NUL. Because we're using strlen() (my fault,
introduced in a731d1 when removing vfs_follow_link()), we could walk off

I2C: runtime: Fix checks which make legacy suspend to never get called
For devices which are not adapted to runtime PM a call to
pm_runtime_suspended always returns true.
Hence the pm_runtime_suspended checks below prevent legacy
suspend from getting called.
So do a pm_runtime_suspended check only for devices with a
dev_pm_ops populated (which hence do not rely on the legacy
suspend)

Enable omap-serial driver in /mach-omap2/Kconfig and

driver addition all omap-uarts can be handled with
omap-serial driver.
With addition of omap-serial driver console parameter
needs be changed in bootargs from ttyS* should be
replaced with ttyO* [O --> OMAP not ZERO]
For example: ttyS0[UART1 on 3430SDP] changes to ttyO0.
But with some boards that do not use omap-uart as console uart.
we need to handle them with 8250 driver. Ex: ZOOM2/3.
For zoom2/3 board we need to use 8250 serial driver and
console parameter will remain ttyS0 which basically uses
a Quad uart placed on the debug board connected through a
gpio line.

serial: Add OMAP high-speed UART driver
This patch adds driver support for OMAP2/3/4 high speed UART.
The driver is made separate from 8250 driver as we cannot
over load 8250 driver with omap platform specific configuration for
features like DMA, it makes easier to implement features like DMA and
hardware flow control and software flow control configuration with
this driver as required for the omap-platform.
This patch involves only the core driver and its dependent.
