717a94b5fc sched/core: Remove 'task' parameter and rename tsk_restore_flags() to current_restore_flags()
It is not safe for one thread to modify the ->flags
of another thread as there is no locking that can protect
the update.

So tsk_restore_flags(), which takes a task pointer and modifies
the flags, is an invitation to do the wrong thing.

All current users pass "current" as the task, so no developers have
accepted that invitation.  It would be best to ensure it remains
that way.

So rename tsk_restore_flags() to current_restore_flags() and don't
pass in a task_struct pointer.  Always operate on current->flags.

Pull block fixes from Jens Axboe:
 "Here's a pull request for 4.11-rc, fixing a set of issues mostly
  centered around the new scheduling framework. These have been brewing
  for a while, but split up into what we absolutely need in 4.11, and
  what we can defer until 4.12. These are well tested, on both single
  queue and multiqueue setups, and with and without shared tags. They
  fix several hangs that have happened in testing.

  This is obviously larger than I would have preferred at this point in
  time, but I don't think we can shave much off this and still get the
  desired results.

  In detail, this pull request contains:

   - a set of five fixes for NVMe, mostly from Christoph and one from
     Roland.

   - a series from Bart, fixing issues with dm-mq and SCSI shared tags
     and scheduling. Note that one of those patches commit messages may
     read like an optimization, but it is in fact an important fix for
     queue restarts in particular.

   - a series from Omar, most importantly fixing a hang with multiple
     hardware queues when we fail to get a driver tag. Another important
     fix in there is for resizing hardware queues, which nbd does when
     handling multiple sockets for one connection.

   - fixing an imbalance in putting the ctx for hctx request allocations
     from Minchan"

97fbfef6bd staging: android: ashmem: lseek failed due to no FMODE_LSEEK.
vfs_llseek will check whether the file mode has
FMODE_LSEEK, no return failure. But ashmem can be
lseek, so add FMODE_LSEEK to ashmem file.

Comment From Greg Hackmann:
	ashmem_llseek() passes the llseek() call through to the backing
	shmem file.  91360b02ab ("ashmem: use vfs_llseek()") changed
	this from directly calling the file's llseek() op into a VFS
	layer call.  This also adds a check for the FMODE_LSEEK bit, so
	without that bit ashmem_llseek() now always fails with -ESPIPE.

Fixes: 91360b02ab ("ashmem: use vfs_llseek()")

6077c2d706 dm rq: Avoid that request processing stalls sporadically
While running the srp-test software I noticed that request
processing stalls sporadically at the beginning of a test, namely
when mkfs is run against a dm-mpath device. Every time when that
happened the following command was sufficient to resume request
processing:

    echo run >/sys/kernel/debug/block/dm-0/state

This patch avoids that such request processing stalls occur. The
test I ran is as follows:

    while srp-test/run_tests -d -r 30 -t 02-mq; do :; done

36e3cf2739 scsi: Avoid that SCSI queues get stuck
If a .queue_rq() function returns BLK_MQ_RQ_QUEUE_BUSY then the block
driver that implements that function is responsible for rerunning the
hardware queue once requests can be queued again successfully.

commit 52d7f1b5c2 ("blk-mq: Avoid that requeueing starts stopped
queues") removed the blk_mq_stop_hw_queue() call from scsi_queue_rq()
for the BLK_MQ_RQ_QUEUE_BUSY case. Hence change all calls to functions
that are intended to rerun a busy queue such that these examine all
hardware queues instead of only stopped queues.

Since no other functions than scsi_internal_device_block() and
scsi_internal_device_unblock() should ever stop or restart a SCSI
queue, change the blk_mq_delay_queue() call into a
blk_mq_delay_run_hw_queue() call.

Fixes: commit 52d7f1b5c2 ("blk-mq: Avoid that requeueing starts stopped queues")
Fixes: commit 7e79dadce2 ("blk-mq: stop hardware queue in blk_mq_delay_queue()")

6118714275 pinctrl: core: Fix pinctrl_register_and_init() with pinctrl_enable()
Recent pinctrl changes to allow dynamic allocation of pins exposed one
more issue with the pinctrl pins claimed early by the controller itself.
This caused a regression for IMX6 pinctrl hogs.

Before enabling the pin controller driver we need to wait until it has
been properly initialized, then claim the hogs, and only then enable it.

To fix the regression, split the code into pinctrl_claim_hogs() and
pinctrl_enable(). And then let's require that pinctrl_enable() is always
called by the pin controller driver when ready after calling
pinctrl_register_and_init().

work for hogs")

30c57f0734 net: ethernet: ti: cpsw: fix race condition during open()
TI's cpsw driver handles both OF and non-OF case for phy
connect. Unfortunately of_phy_connect() returns NULL on
error while phy_connect() returns ERR_PTR().

To handle this, cpsw_slave_open() overrides the return value
from phy_connect() to make it NULL or error.

This leaves a small window, where cpsw_adjust_link() may be
invoked for a slave while slave->phy pointer is temporarily
set to -ENODEV (or some other error) before it is finally set
to NULL.

_cpsw_adjust_link() only handles the NULL case, and an oops
results when ERR_PTR() is seen by it.

Note that cpsw_adjust_link() checks PHY status for each
slave whenever it is invoked. It can so happen that even
though phy_connect() for a given slave returns error,
_cpsw_adjust_link() is still called for that slave because
the link status of another slave changed.

Fix this by using a temporary pointer to store return value
of {of_}phy_connect() and do a one-time write to slave->phy.

794a8604fe PCI: dwc: Fix dw_pcie_ops NULL pointer dereference
Fix a crash from dereferencing a NULL dw_pcie_ops pointer.  For example,
on ARTPEC-6:

  Unable to handle kernel NULL pointer dereference at virtual address 00000004
  pgd = c0204000
  [00000004] *pgd=00000000
  Internal error: Oops: 5 [#1] SMP ARM
  Modules linked in:
  CPU: 0 PID: 1 Comm: swapper/0 Not tainted 4.11.0-rc3-next-20170321 #1
  Hardware name: Axis ARTPEC-6 Platform
  task: db098000 task.stack: db096000
  PC is at dw_pcie_writel_dbi+0x2c/0xd0

Prior to 442ec4c04d ("PCI: dwc: all: Split struct pcie_port into
host-only and core structures"), every driver had a struct pcie_host_ops
with function pointers, typically used as:

  if (pp->ops->readl_rc)
    return pp->ops->readl_rc(...);

442ec4c04d split struct pcie_host_ops into two pieces: struct
dw_pcie_host_ops and struct dw_pcie_ops, so the above became:

  if (pci->ops->readl_dbi)
    return pci->ops->readl_dbi(...);

But pcie-artpec6.c and pcie-designware-plat.c don't need the dw_pcie_ops
pointers and didn't supply a pci->ops struct, which leads to NULL pointer
dereferences.

Supply an empty struct dw_pcie_ops to avoid the NULL pointer dereferences.

feb199ebef PCI: thunder-pem: Fix legacy firmware PEM-specific resources
SZ_16M PEM resource size includes PEM-specific register and its children
resources. Reservation of the whole SZ_16M range leads to child device
driver failure when pcieport driver is requesting resources:

  pcieport 0004:1f:00.0: can't enable device: BAR 0 [mem 0x87e0c0f00000-0x87e0c0ffffff 64bit] not claimed

So we cannot reserve full 16M here and instead we want to reserve
PEM-specific register only which is SZ_64K.

At the end increase PEM resource to SZ_16M since this is what
thunder_pem_init() call expects for proper initialization.

We should be detaching the MMU before destroying the address
space. To do this cleanly, the detach has to happen in

in adreno_gpu.c.  Plus it is better symmetry to have

a5fef535c5 drm/msm/dsi: Fix bug in dsi_mgr_phy_enable
A recent commit introduces a bug in dsi_mgr_phy_enable. In the non
dual DSI mode, we reset the mdsi (master DSI) PHY. This isn't right
since master and slave DSI exist only in dual DSI mode. For the normal
mode of operation, we should simply reset the PHY of the DSI device
(i.e. msm_dsi) corresponding to the current bridge.

Usage of the wrong DSI pointer also resulted in a static checker
warning. That too is resolved with this fix.

Pull scheduler fixes from Thomas Gleixner:
 "This update provides:

   - make the scheduler clock switch to unstable mode smooth so the
     timestamps stay at microseconds granularity instead of switching to
     tick granularity.

   - unbreak perf test tsc by taking the new offset into account which
     was added in order to proveide better sched clock continuity

   - switching sched clock to unstable mode runs all clock related
     computations which affect the sched clock output itself from a work
     queue. In case of preemption sched clock uses half updated data and
     provides wrong timestamps. Keep the math in the protected context
     and delegate only the static key switch to workqueue context.

   - remove a duplicate header include"

bba6d9e47f iio: hid-sensor-attributes: Fix sensor property setting failure.
When system bootup without get sensor property, set sensor
property will be fail.

If no get_feature operation done before set_feature, the sensor
properties will all be the initialized value, which is not the
same with sensor real properties. When set sensor property it will
write back to sensor the changed perperty data combines with other
sensor properties data, it is not right and may be dangerous.

In order to get all sensor properties, choose to read one of the sensor
properties(no matter read any sensor peroperty, driver will get all
the peroperties and return the requested one).

862d1d89ad iio: accel: hid-sensor-accel-3d: Fix duplicate scan index error
When both accel_3d and gravity sensor are present, iio_device_register()
fails with "Duplicate scan index" error.
The reason for this is setting of indio_dev->num_channels based on
accel_3d channel for both gravity and accel-3d sensor. But number of
channels are not same, so for gravity it is pointing to some invalid
memory and getting scan_index to compare which may match.
To fix this issue, set the indio_dev->num_channels correctly based on
the sensor type.

Thirteen small fixes: The hopefully final effort to get the lpfc nvme
 kconfig problems sorted, there's one important sg fix (user can induce
 read after end of buffer) and one minor enhancement (adding an extra
 PCI ID to qedi). The rest are a set of minor fixes, which mostly occur
 as user visible in error legs or on specific devices.
