If we hit any errors in btrfs_lookup_csums_range, we'll loop through all
the csums we allocate and free them. But the code was using list_entry
incorrectly, and ended up trying to free the on-stack list_head instead.
This bug came from commit 0678b6185

0650f855d2e4b0b9 ("ARM: imx_v4_v5_defconfig: Select CONFIG_IMX_WEIM") CONFIG_SPI
selection was dropped by savedefconfig for imx_v4_v5_defconfig and
imx_v6_v7_defconfig.
In order to keep the same behaviour as previous kernel versions and avoid
regressions, let's add CONFIG_SPI option back.

There are only 4 CTAR registers (CTAR0 - CTAR3) so we can only use the
lower 2 bits of the chip select to select a CTAR register.
SPI_PUSHR_CTAS used the lower 3 bits which would result in wrong bit values
if the chip selects 4/5 are used. For those chip selects SPI_CTAR even
calculated offsets of non-existing registers.

The string property read helpers will run off the end of the buffer if
it is handed a malformed string property. Rework the parsers to make
sure that doesn't happen. At the same time add new test cases to make
sure the functions behave themselves.
The original implementations of of_property_read_string_index() and
of_property_count_strings() both open-coded the same block of parsing
code, each with it's own subtly different bugs. The fix here merges
functions into a single helper and makes the original functions static
inline wrappers around the helper.
One non-bugfix aspect of this patch is the addition of a new wrapper,
of_property_read_string_array(). The new wrapper is needed by the
device_properties feature that Rafael is working on and planning to
merge for v3.19. The implementation is identical both with and without
the new static inline wrapper, so it just got left in to reduce the
churn on the header file.

sched_move_task() is the only interface to change sched_task_group:
cpu_cgrp_subsys methods and autogroup_move_group() use it.
Everything is synchronized by task_rq_lock(), so cpu_cgroup_attach()
is ordered with other users of sched_move_task(). This means we do no
need RCU here: if we've dereferenced a tg here, the .attach method
hasn't been called for it yet.
Thus, we should pass "true" to task_css_check() to silence lockdep
warnings.

So far, the required PLL's (PLL1/PLL2/PLL5) have been initialized
by boot loader and the kernel code defined fixed rates according
to those default configurations. Beginning with the USB PLL7 the
code started to initialize the PLL's itself (using imx_clk_pllv3).
However, since commit dc4805c2e78ba5a22ea1632f3e3e4ee601a1743b
(ARM: imx: remove ENABLE and BYPASS bits from clk-pllv3 driver)
imx_clk_pllv3 no longer takes care of the ENABLE and BYPASS bits,
hence the USB PLL were not configured correctly anymore.
This patch not only fixes those USB PLL's, but also makes use of
the imx_clk_pllv3 for all PLL's and alignes the code with the PLL
support of the i.MX6 series.

It is safe to call notify disconnect when the usb core
thinks the device is disconnected.
This commit also fixes one bug found at below situation:
we have not enabled usb wakeup, we do system suspend when
there is an usb device at the port, after suspend, we plug out
the usb device, then plug in device again. At that time,
the nofity disconnect was not called at current code, as
the controller doesn't know the usb device was disconnected
during the suspend, but USB core knows the port has changed
during that periods.
So to fix this problem, and let the usb core call notify disconnect.

(port_dev->child, the child device at roothub is not NULL), we

Streams seem to be broken on the Asmedia 1042. An uas capable Seagate disk
which is known to work fine with other controllers causes the system to freeze
when connected over usb-3 with this controller, where as it works fine with
uas in usb-2 ports, indicating a problem with streams.
This is a bit bigger hammer then I would like to use for this, but for now it
will have to make do. I've ordered a pci-e usb controller card with an Asmedia
1042, once that arrives I'll try to get streams to work (with a quirk flag if
necessary) and then we can re-enable them. For now this at least makes uas
capable disk enclosures work again by forcing fallback to the usb-storage
driver.

Sometimes mass-storage devices using the Bulk-only transport will
mistakenly skip the data phase of a command. Rather than sending the
data expected by the host or sending a zero-length packet, they go
directly to the status phase and send the CSW.
This causes problems for usb-storage, for obvious reasons. The driver
will interpret the CSW as a short data transfer and will wait to
receive a CSW. The device won't have anything left to send, so the
command eventually times out.
The SCSI layer doesn't retry commands after they time out (this is a
relatively recent change). Therefore we should do our best to detect
a skipped data phase and handle it promptly.
This patch adds code to do that. If usb-storage receives a short
13-byte data transfer from the device, and if the first four bytes of
the data match the CSW signature, the driver will set the residue to
the full transfer length and interpret the data as a CSW.
This fixes Bugzilla #86611.

This commit fixes this by not allowing usb_alloc_streams to continue if

Note that we do allow usb_free_streams to continue after a (logical)

When VLAN is in use in macvtap_put_user, we end up setting
csum_start to the wrong place. The result is that the whoever

of writing the checksum to the expected location, usually this
means writing the checksum with an offset of -4.

The root cause is that eth1 is not opened and clock is not enabled, and .suspend() still
call .fec_enet_clk_enable() to disable clock.
To avoid the broken, let it check network device up status by calling .netif_running()
before disable/enable clocks.

====================
tun: Fix csum_start and TUN_PKT_STRIP
The first patch fixes a serious problem that breaks checksum offload
in VMs while the second patch fixes a problem that probably affects
no one.

We set the flag TUN_PKT_STRIP if the user buffer provided is too
small to contain the entire packet plus meta-data. However, this
has been broken ever since we added GSO meta-data. VLAN acceleration
also has the same problem.
This patch fixes this by taking both into account when setting the
TUN_PKT_STRIP flag.
The fact that this has been broken for six years without anyone
realising means that nobody actually uses this flag.

When VLAN acceleration is in use on the xmit path, we end up
setting csum_start to the wrong place. The result is that the
whoever ends up doing the checksum setting will corrupt the packet
instead of writing the checksum to the expected location, usually
this means writing the checksum with an offset of -4.
This patch fixes this by adjusting csum_start when VLAN acceleration
is detected.

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.

The makefile for sanitizing kernel headers uses the kbuild file
to determine which files to do. Several networking related headers
were missing. Without these headers iproute2 build would break.
