Running ftracetests on a box that mounted debugfs in two locations
made the ftracetests fail. This is because the tests uses a grep
of debugfs from the /proc/mounts file to find the debugfs mount
point, and then appends "/tracing" to that string to get the tracing
directory.
If the debugfs directory is mounted twice, then that grep will return
two answers and appending "/tracing" to a string with two lines will
not work.
Use "head -1" to only take the first mount point found.

Even if a gpio pin is set to output, we still need to set INPUT_EN
functionality (by clearing INPUT_EN bit) to be able to read the pin's
level.
E.g. without this change, we'll always read low level state from sysfs.

If not, the io based irq will never be detected.
However, this bit can sometimes be misconfigured (BIOS issue).

according to the declaration parameters order in cma.h, he will run into

Commit 95b0e655f914 ("ARM: mm: don't limit default CMA region only to
low memory") extended CMA memory reservation to allow usage of high
memory. It relied on commit f7426b983a6a ("mm: cma: adjust address limit
to avoid hitting low/high memory boundary") to ensure that the reserved
block never crossed the low/high memory boundary. While the
implementation correctly lowered the limit, it failed to consider the
case where the base..limit range crossed the low/high memory boundary
with enough space on each side to reserve the requested size on either
low or high memory.
Rework the base and limit adjustment to fix the problem. The function
now starts by rejecting the reservation altogether for fixed
reservations that cross the boundary, tries to reserve from high memory
first and then falls back to low memory.

The fixed parameter to cma_declare_contiguous() tells the function
whether the given base address must be honoured or should be considered
as a hint only. The API considers a zero base address as meaning any
base address, which must never be considered as a fixed value.
Part of the implementation correctly checks both fixed and base != 0,
but two locations check the fixed value only. Set fixed to false when
base is 0 to fix that and simplify the code.

If activation of the CMA area fails its mutex won't be initialized,
leading to an oops at allocation time when trying to lock the mutex. Fix
this by setting the cma area count field to 0 when activation fails,
leading to allocation returning NULL immediately.

This patch has ceph's lib code use the memalloc flags.
If the VM layer needs to write data out to free up memory to handle new
allocation requests, the block layer must be able to make forward progress.
To handle that requirement we use structs like mempools to reserve memory for
objects like bios and requests.
The problem is when we send/receive block layer requests over the network
layer, net skb allocations can fail and the system can lock up.
To solve this, the memalloc related flags were added. NBD, iSCSI
and NFS uses these flags to tell the network/vm layer that it should
use memory reserves to fullfill allcation requests for structs like
skbs.
I am running ceph in a bunch of VMs in my laptop, so this patch was
not tested very harshly.

Pull ARM SoC fixes from Olof Johansson:
"A surprisingly small batch of fixes for -rc3. Suspiciously small, I'd
say.
Anyway, most of this are a few defconfig updates. Some for omap to
deal with kernel binary size (moving ipv6 to module, etc). A larger
one for socfpga that refreshes with some churn, but also turns on a
few options that makes the newly-added board in my bootfarm usable for
testing.
OMAP3 will also now warn when booted with legacy (non-DT) boot
protocols, hopefully encouraging those who still care about some of
those platforms to submit DT support and report bugs where needed.
Nothing stops working though, this is just to warn for future
deprecation.
Beyond this, very few actual bugfixes. A PXA fix for DEBUG_LL boot
hangs, a missing terminting entry in a dt_match array on RealView a
MTD fix on OMAP with NAND"

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes
Merge "omap fixes against v3.18-rc2" from Tony Lindgren:
Few fixes for omaps to enable NAND BCH so devices won't
produce errors when booted with omap2plus_defconfig, and
reduce bloat by making IPV6 a loadable module.
Also let's add a warning about legacy boot being deprecated
for omap3.
We now have things working with device tree, and only omap3 is
still booting in legacy mode. So hopefully this warning will
help move the remaining legacy mode users to boot with device
tree.
As the total reduction of code and static data is somewhere
around 20000 lines of code once we remove omap3 legacy mode
booting, we really do want to make omap3 to boot also in
device tree mode only over the next few merge cycles.

We're moving omaps to use device tree based booting and already have
omap2, omap4, omap5, am335x and am437x booting in device tree only
mode.
Only omap3 still has legacy booting still around and we really want
to make that device tree only. So let's add a warning about deprecated
legacy booting so we get people to upgrade their boards to use device
tree based booting and find out about any remaining issues.
Note that for most boards we already have the .dts file and those can
be booted with without changing the bootloader using the appended
DTB mode.

Merge "SOCFPGA defconfig update" from Dinh Nguyen:
Remove extra un-used options in the socfpga_defconfig by doing
"make savedefconfig". Along with this commit, add the configs to enable
support for most filesystems, add regulator and SRAM support, and time
stamps on printk().

The commit 2111667b4677 ("ARM: pxa: call debug_ll_io_init for
earlyprintk") triggers in the current kernel the attached backtrace on
PXA/tosa early in the boot time when DEBUG_LL is enabled.
It is due to overlap between uart virtual memory defined in
DEBUG_UART_VIRT and mapped by debug_ll_io_init() and peripheral bus
mapped by pxa_map_io at the same address, 0xf2100000.
As hinted by Arnd, map early virtual memory for low level debug on
address 0xf6200000, even if that means 2 virtual mappings will give
access to the pxa internal UARTs (FFUART, BTUART, STUART, ...).

Pull MTD fixes from Brian Norris:
"Three main MTD fixes for 3.18:
- A regression from 3.16 which was noticed in 3.17. With the
restructuring of the m25p80.c driver and the SPI NOR library
framework, we omitted proper listing of the SPI device IDs. This
means m25p80.c wouldn't auto-load (modprobe) properly when built as
a module. For now, we duplicate the device IDs into both modules.
- The OMAP / ELM modules were depending on an implicit link ordering.
Use deferred probing so that the new link order (in 3.18-rc) can
still allow for successful probing.
- Fix suspend/resume support for LH28F640BF NOR flash"

After '#echo mem > /sys/power/state' some devices can not be properly resumed
because apparently the MTD Partition Configuration Register has been reset
to default thus the rootfs cannot be mounted cleanly on resume.
An example of this can be found in the SA-1100 Developer's Manual at 9.5.3.3
where the second step of the Sleep Shutdown Sequence is described:
"An internal reset is applied to the SA-1100. All units are reset...".
As workaround we refresh the PCR value as done initially on chip setup.
This behavior and the fix are confirmed by our tests done on 2 different Zaurus
collie units with kernel 3.17.

Since commit 6d178ef2fd5e ("mtd: nand: Move ELM driver and rename as
omap_elm"), I don't have any mtd devices present on my am335x. This
changes the link order of the omap_elm and omap2 objects, causing them
to probe in the wrong order.
To fix this, make elm_config defer probing until the omap_elm driver is
actually loaded.

m25p80's device ID table is now spi_nor_ids, defined in spi-nor. The
MODULE_DEVICE_TABLE() macro doesn't work with extern definitions, but
its use was also removed at the same time. Now if m25p80 is built as
a module it doesn't get the necessary aliases to be loaded
automatically.
A clean solution to this will involve defining the list of device
IDs in spi-nor.h and removing struct spi_device_id from the spi-nor
API, but this is quite a large change.
As a quick fix suitable for stable, copy the device IDs back into
m25p80.

Drivers currently call spi_nor_match_id() and then spi_nor_scan().
This adds a dependency on struct spi_device_id which we want to
avoid. Make spi_nor_scan() do it for them.

This pull-request includes some bug fixes and code cleanups.
Especially, this fixes the bind failure issue occurred when it tries
to re-bind Exynos drm driver after unbound, and the modetest failure
issue incurred by not having a pair to vblank on and off requests.

During system suspend after connector switch off its dpms field
is set to connector previous dpms state. To properly resume dpms field
should be set to its actual state (off) before resuming to previous dpms state.

Before DPMS off driver disables vblank.
It should be balanced by vblank enable after DPMS on.
The patch fixes issue with page_flip ioctl not being able
to acquire vblank counter introduced by patch:
drm: Always reject drm_vblank_get() after drm_vblank_off()
