381676d5e8 iio:bma180: Fix scale factors to report correct acceleration units
The userspace interface for acceleration sensors is documented as using
m/s^2 units [Documentation/ABI/testing/sysfs-bus-iio]

The fullscale raw values for the BMA80 corresponds to -/+ 1, 1.5, 2, etc G
depending on the selected mode.

The scale table was converting to G rather than m/s^2.
Change the scaling table to match the documented interface.

See commit 71702e6e, iio: mma8452: Use correct acceleration units,
for a related fix.

72dd2b2a44 Bluetooth: Fix endian and alignment issue with ath3k version handling
The ath3k driver is treating the version information badly when it
comes to loading the right firmware version and comparing that it
actually matches with the hardware.

Initially this showed up as this:

  CHECK   drivers/bluetooth/ath3k.c
drivers/bluetooth/ath3k.c:373:17: warning: cast to restricted __le32
drivers/bluetooth/ath3k.c:435:17: warning: cast to restricted __le32

However when fixing this by actually using __packed and __le32 for
the ath3_version structure, more issues came up:

  CHECK   drivers/bluetooth/ath3k.c
drivers/bluetooth/ath3k.c:381:32: warning: incorrect type in assignment (different base types)
drivers/bluetooth/ath3k.c:381:32:    expected restricted __le32 [usertype] rom_version
drivers/bluetooth/ath3k.c:381:32:    got int [signed] <noident>
drivers/bluetooth/ath3k.c:382:34: warning: incorrect type in assignment (different base types)
drivers/bluetooth/ath3k.c:382:34:    expected restricted __le32 [usertype] build_version
drivers/bluetooth/ath3k.c:382:34:    got int [signed] <noident>
drivers/bluetooth/ath3k.c:386:28: warning: restricted __le32 degrades to integer
drivers/bluetooth/ath3k.c:386:56: warning: restricted __le32 degrades to integer

This patch fixes every instance of the firmware version handling and
makes sure it is endian safe and uses proper unaligned access.

61bd55ce16 iio: buffer: Fix demux table creation
When creating the demux table we need to iterate over the selected scan mask for
the buffer to get the samples which should be copied to destination buffer.
Right now the code uses the mask which contains all active channels, which means
the demux table contains entries which causes it to copy all the samples from
source to destination buffer one by one without doing any demuxing.

d1d588c181 Bluetooth: Disable HCI_CONNECTABLE based passive scanning for now
When HCI_CONNECTABLE is set the code has been enabling passive scanning
in order to be consistent with BR/EDR and accept connections from any
device doing directed advertising to us. However, some hardware
(particularly CSR) can get very noisy even when doing duplicates
filtering, making this feature waste resources.

Considering that the feature is for fairly corner-case use (devices
who'd use directed advertising would likely be in the whitelist anyway)
it's better to disable it for now. It may still be brought back later,
possibly with a better implementation (e.g. through improved scan
parameters).

I2C block transfers can have a size up to 32 bytes. If starting close
to the end of the address space, there may not be enough room to write
that many bytes (on I2C block writes) or not enough bytes to be read
(on I2C block reads.) In that case, we must shorten the transfer so
that it does not exceed the address space.

 This pulls in the for-3.17/fuse-move, for-3.17/dt-cros-ec-kbd and

 Note that the Apalis T30 support has a runtime dependency on the

 in that order. I didn't merge that branch into this because Apalis T30
 support is new, therefore can't regress, and because the dependency

Merge tag 'tegra-for-3.17-xusb-padctl' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux into next/dt

Merge "ARM: tegra: Add XUSB pad controller support" from Thierry Reding:

Adds device tree bindings and a driver for the XUSB pad controller found
on Tegra114 and later. This is a prerequisites for PCIe, SATA and XUSB
drivers which are all currently being reviewed or pending for merge.

This is a separate branch in case it needs to be pulled into the pinctrl
tree to resolve conflicts.

b776eec135 ARM: tegra: rework PCIe regulators
This branch reworks the set of regulators that the Tegra PCIe driver
 uses, so that the driver and DT bindings more correctly model what's
 really going on in HW. For backwards-compatibility the driver will
 fallback to using the old set of regulators if the new ones can't be
 found.
 
 I've made this a separate branch in case it needs to be pulled into the
 PCIe tree to resolve any conflicts.

c6b659c005 ARM: tegra: core code changes for 3.17
Some of the code that's currently called from the Tegra machine setup
 code is moved to regular initcalls. To catch dependency violations, the
 various code paths now WARN if they're called to early. Not all of the
 potential candidates are converted yet, but those that were have been
 verified to work across all supported Tegra generations.
 
 A new function, soc_is_tegra(), is also provided to make sure that the
 initcalls can abort early if they aren't run on Tegra, which can happen
 for multi-platform builds.
 
 Finally this also moves out the PMC driver to drivers/soc/tegra so that
 it can be shared with 64-bit ARM.
 
 This is based on the for-3.17/fuse-move branch. The split is somewhat
 arbitrary but allows the dependents of the for-3.17/fuse-move to pull
 in as little code as necessary.

23e892929e ARM: tegra: move fuse code out of arch/arm
This branch moves code related to the Tegra fuses out of arch/arm and
 into a centralized location which could be shared with ARM64. It also
 adds support for reading the fuse data through sysfs.
 
 Included is also some preparatory work that moves Tegra-related header
 files from include/linux to include/soc/tegra as suggested by Arnd.
 
 Furthermore the Tegra chip ID is now retrieved using a function rather
 than a variable so that sanity checks can be done. This is convenient
 in subsequent patches that will move some of the code that's currently
 called from Tegra machine setup into regular initcalls so that it can
 be reused on 64-bit ARM. The sanity checks help with verifying that no
 code tries to obtain the Tegra chip ID before the underlying driver is
 properly initialized.

0bfaa9c5cb btrfs: test for valid bdev before kobj removal in btrfs_rm_device
commit 99994cd btrfs: dev delete should remove sysfs entry
added a btrfs_kobj_rm_device, which dereferences device->bdev...
right after we check whether device->bdev might be NULL.

I don't honestly know if it's possible to have a NULL device->bdev
here, but assuming that it is (given the test), we need to move
the kobject removal to be under that test.

(Coverity spotted this)

98ce2deda2 Btrfs: fix abnormal long waiting in fsync
xfstests generic/127 detected this problem.

With commit 7fc34a62ca, now fsync will only flush
data within the passed range.  This is the cause of the above problem,
-- btrfs's fsync has a stage called 'sync log' which will wait for all the
ordered extents it've recorded to finish.

In xfstests/generic/127, with mixed operations such as truncate, fallocate,
punch hole, and mapwrite, we get some pre-allocated extents, and mapwrite will
mmap, and then msync.  And I find that msync will wait for quite a long time
(about 20s in my case), thanks to ftrace, it turns out that the previous
fallocate calls 'btrfs_wait_ordered_range()' to flush dirty pages, but as the
range of dirty pages may be larger than 'btrfs_wait_ordered_range()' wants,
there can be some ordered extents created but not getting corresponding pages
flushed, then they're left in memory until we fsync which runs into the
stage 'sync log', and fsync will just wait for the system writeback thread
to flush those pages and get ordered extents finished, so the latency is
inevitable.

This adds a flush similar to btrfs_start_ordered_extent() in
btrfs_wait_logged_extents() to fix that.
