git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux into fixes
Merge "ARM: imx: fixes for 3.18, 2nd round" from Shawn Guo:
"This is the second round of i.MX fixes for 3.18. The clk-vf610 fix is
relatively big, because it needs some adaption to the change made by
offending commit dc4805c2e78b (ARM: imx: remove ENABLE and BYPASS bits
from clk-pllv3 driver). And it should have been sent to you for earlier
-rc inclusion, but unfortunately it got delayed for some time because
Stefan wasn't aware of my email address change."
The i.MX fixes for 3.18, 2nd round:
- Fix a regression on Vybrid platform which is caused by commit
dc4805c2e78b (ARM: imx: remove ENABLE and BYPASS bits from clk-pllv3
driver), and results in a missing configuration on PLL clocks.
- Fix a regression with i.MX defconfig files where CONFIG_SPI option
gets lost accidentally.

If the OPEN rpc call to the server fails with an ENOENT call, nfs_atomic_open
will create a negative dentry for that file, however it currently fails
to call nfs_set_verifier(), thus causing the dentry to be immediately
revalidated on the next call to nfs_lookup_revalidate() instead of following
the usual lookup caching rules.

Thermal hysteresis represents a temperature difference.
But the original code treats it as a temperature value,
Convert it from tenths of degree Kelvin to Milli-Celsius
by deducing 273200. This is not right.
Kelvin and Celsius have same degree size. From temperature
difference view, the conversion between tenths of degree
Kelvin unit and Milli-Celsius unit is just to multiply 100.

q->mq_usage_counter is a percpu_ref which is killed and drained when
the queue is frozen. On a CPU hotplug event, blk_mq_queue_reinit()
which involves freezing the queue is invoked on all existing queues.
Because percpu_ref killing and draining involve a RCU grace period,
doing the above on one queue after another may take a long time if
there are many queues on the system.
This patch splits out initiation of freezing and waiting for its
completion, and updates blk_mq_queue_reinit_notify() so that the
queues are frozen in parallel instead of one after another. Note that
freezing and unfreezing are moved from blk_mq_queue_reinit() to
blk_mq_queue_reinit_notify().

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

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.

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.

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.

The problem is the following call sequence (simplified):
1) usb_reset_device
2) usb_reset_and_verify_device
2) hub_port_init
3) hub_port_finish_reset
3) xhci_discover_or_reset_device
This frees xhci->devs[slot_id]->eps[ep_index].ring for all eps but 0
4) usb_get_device_descriptor
This fails
5) hub_port_init fails
6) usb_reset_and_verify_device fails, does not restore device config
7) uas_post_reset
8) xhci_alloc_streams
NULL deref on the free-ed ring
This commit fixes this by not allowing usb_alloc_streams to continue if
the device is not configured.
Note that we do allow usb_free_streams to continue after a (logical)
disconnect, as it is necessary to explicitly free the streams at the xhci
controller level.

When a subdriver is rmmod-ed then re-insmod-ed, the hid device is not
destroyed as it is owned by the transport layer.
So when we re-probed the device, the hid device is assumed to be already
claimed, and can lead to page faults if hid-core tries to forward the
emitted data to the to-be-created claimed node.

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"
