Pull slave-dmaengine updates from Vinod Koul:
"This time we have Andy updates on dw_dmac which is attempting to make
this IP block available as PCI and platform device though not fully
complete this time.
We also have TI EDMA moving the dma driver to use dmaengine APIs, also
have a new driver for mmp-tdma, along with bunch of small updates.
Now for your excitement the merge is little unusual here, while
merging the auto merge on linux-next picks wrong choice for pl330
(drivers/dma/pl330.c) and this causes build failure. The correct
resolution is in linux-next. (DMA: PL330: Fix build error) I didn't
back merge your tree this time as you are better than me so no point
in doing that for me :)"
Fixed the pl330 conflict as in linux-next, along with trivial header
file conflicts due to changed includes.

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes
From Tony Lindgren:
These were agreed to be merged via arm soc tree as Rafael
is on vacation.
From Kevin Hilman <khilman@deeprootsystems.com>:
This series a couple bug fixes and a couple fixes that make this
driver support recently added OMAP-based SoCs.
The 'get_cpu_device' patch is needed due to a change in the OMAP
OMAP PM core code which enforces use of get_cpu_device() instead of
a deprecated OMAP-specific API.
The usage of plat/*.h headers breaks single zImage, so platforms are
cleaning up and/or removing plat/*.h so the driver needs to be fixed
accordingly.
This series is based on the merge of Rafael's pm-for-3.7-rc1 tag into
Linus' master branch: commit 16642a2e7be23bbda013fc32d8f6c68982eab603.

In case of error, the function get_inode() returns ERR_PTR().
But the users hppfs_lookup() and hppfs_fill_super() use NULL
test for check the return value, not IS_ERR(), so we'd better
change the return value of get_inode() to NULL instead of
ERR_PTR().

The it8152 PCI host used on the pxa/cm_x2xx machines
uses the old-style I/O window registration. This should
eventually get converted to pci_ioremap_io() but for
now, let's cast the IT8152_IO_BASE constant to an integer
type to get rid of the warnings.
Without this patch, building cm_x2xx_defconfig results in:

This is the revised patch for fixing rds-ping spinlock recursion
according to Venkat's suggestions.
RDS ping/pong over TCP feature has been broken for years(2.6.39 to
3.6.0) since we have to set TCP cork and call kernel_sendmsg() between
ping/pong which both need to lock "struct sock *sk". However, this
lock has already been hold before rds_tcp_data_ready() callback is
triggerred. As a result, we always facing spinlock resursion which
would resulting in system panic.
Given that RDS ping is only used to test the connectivity and not for
serious performance measurements, we can queue the pong transmit to
rds_wq as a delayed response.

Fengguang reported a kernel build failure as following:
drivers/built-in.o: In function `pch_gbe_ioctl':
pch_gbe_main.c:(.text+0x510370): undefined reference to `pch_ch_control_write'
pch_gbe_main.c:(.text+0x510393): undefined reference to `pch_ch_control_write'
pch_gbe_main.c:(.text+0x5103b3): undefined reference to `pch_ch_control_write'
...
It's a regression by commit da1586461. The root cause is that
the CONFIG_PPS is not set there, consequently CONFIG_PTP_1588_CLOCK
can not be set anyway, which finally causes ptp_pch and pch_gbe_main
build failures.
As David prefers to use *select* to fix such module co-dependency issues,
this patch explicitly selects all the possible dependencies of PCH_PTP.

Fix two bugs of the /dev/fw* character device concerning the
FW_CDEV_IOC_GET_INFO ioctl with nonzero fw_cdev_get_info.bus_reset.
(Practically all /dev/fw* clients issue this ioctl right after opening
the device.)
Both bugs are caused by sizeof(struct fw_cdev_event_bus_reset) being 36
without natural alignment and 40 with natural alignment.
1) Memory corruption, affecting i386 userland on amd64 kernel:
Userland reserves a 36 bytes large buffer, kernel writes 40 bytes.
This has been first found and reported against libraw1394 if
compiled with gcc 4.7 which happens to order libraw1394's stack such
that the bug became visible as data corruption.
2) Information leak, affecting all kernel architectures except i386:
4 bytes of random kernel stack data were leaked to userspace.
Hence limit the respective copy_to_user() to the 32-bit aligned size of
struct fw_cdev_event_bus_reset.

Russell fixed this bogus warning before in 2f3eca8b4f "Shut up gcc
warning in assabet.c", but apparently gcc has become smarter (or dumber)
since 2005, and the same warning came up again.
This uses the uninitialized_var() macro to convince gcc that the
variable is actually being initialized. 100 times in fact.
Without this patch, building assabet_defconfig results in:

Patch 35f2b0bd59 "ARM: shmobile: Move definition of shmobile_init_late()
to header" moved the definition of the shmobile_init_late function, but
dropped the __init annotation, which is now causing warnings because
the function calls shmobile_suspend_init, which is also marked init.
Without this patch, building kota2_defconfig results in:
WARNING: vmlinux.o(.text+0xb7c8): Section mismatch in reference from the function shmobile_init_late() to the function .init.text:shmobile_suspend_init()
The function shmobile_init_late() references
the function __init shmobile_suspend_init().
This is often because shmobile_init_late lacks a __init
annotation or the annotation of shmobile_suspend_init is wrong.

It's just annoying and the user will have gotten a nice OOM killer message
so they are already fully aware they are screwed :). Thanks,

We were freeing non-existent pages which was causing a panic for a user who
was suffering from ENOMEM. This patch fixes the problem. Thanks,

So far the return code of barrier_all_devices() is ignored, which
means that errors are ignored. The result can be a corrupt
filesystem which is not consistent.
This commit adds code to evaluate the return code of
barrier_all_devices(). The normal btrfs_error() mechanism is used to
switch the filesystem into read-only mode when errors are detected.
In order to decide whether barrier_all_devices() should return
error or success, the number of disks that are allowed to fail the
barrier submission is calculated. This calculation accounts for the
worst RAID level of metadata, system and data. If single, dup or
RAID0 is in use, a single disk error is already considered to be
fatal. Otherwise a single disk error is tolerated.
The calculation of the number of disks that are tolerated to fail
the barrier operation is performed when the filesystem gets mounted,
when a balance operation is started and finished, and when devices
are added or removed.

In check-integrity, detect when a superblock is written that points
to blocks that have not been written to disk due to I/O write errors.

If a filesystem is mounted with compression and then remounted by adding nodatacow,
the compression is disabled but the compress flag is still visible.
Also, if a filesystem is mounted with nodatacow and then remounted with compression,
nodatacow flag is still present but it's not active.
This patch:
- removes compress flags and notifies that the compression has been disabled if the
filesystem is mounted with nodatacow
- removes nodatacow and nodatasum flags if mounted with compress.

We can just copy the in memory inode into the tree log directly, no sense in
updating the fs tree so we can copy it into the tree log tree. Thanks,

When building btrfs from kernel code, it will report:

fs/btrfs/extent_io.h:281: warning: previous declaration of 'extent_buffer_page' was here

because of the wrong declaration of inline functions.

Because the value of extent_map is only a correct value or NULL,
so IS_ERR is unnecessary.
