869ab90f0a block: constify struct blk_integrity_profile
blk_integrity_profile's are never modified, so mark them 'const' so that
they are placed in .rodata and benefit from memory protection.

ea174c9573 RDMA/iser: Fix possible mr leak on device removal event
When the rdma device is removed, we must cleanup all
the rdma resources within the DEVICE_REMOVAL event
handler to let the device teardown gracefully. When
this happens with live I/O, some memory regions are
occupied. Thus, track them too and dereg all the mr's.

We are safe with mr access by iscsi_iser_cleanup_task.

b7363e67b2 IB/device: Convert ib-comp-wq to be CPU-bound
This workqueue is used by our storage target mode ULPs
via the new CQ API. Recent observations when working
with very high-end flash storage devices reveal that
UNBOUND workqueue threads can migrate between cpu cores
and even numa nodes (although some numa locality is accounted
for).

While this attribute can be useful in some workloads,
it does not fit in very nicely with the normal
run-to-completion model we usually use in our target-mode
ULPs and the block-mq irq<->cpu affinity facilities.

The whole block-mq concept is that the completion will
land on the same cpu where the submission was performed.
The fact that our submitter thread is migrating cpus
can break this locality.

We assume that as a target mode ULP, we will serve multiple
initiators/clients and we can spread the load enough without
having to use unbound kworkers.

Also, while we're at it, expose this workqueue via sysfs which
is harmless and can be useful for debug.

9fcd67d177 IB/rxe: increment msn only when completing a request
According to C9-147, MSN should only be incremented when the last packet of
a multi packet request has been received.

"Logically, the requester associates a sequential Send Sequence Number
(SSN) with each WQE posted to the send queue. The SSN bears a one-
to-one relationship to the MSN returned by the responder in each re-
sponse packet. Therefore, when the requester receives a response, it in-
terprets the MSN as representing the SSN of the most recent request
completed by the responder to determine which send WQE(s) can be
completed."

0957c29f78 IB/core: Restore I/O MMU, s390 and powerpc support
Avoid that the following error message is reported on the console
while loading an RDMA driver with I/O MMU support enabled:

DMAR: Allocating domain for mlx5_0 failed

Ensure that DMA mapping operations that use to_pci_dev() to
access to struct pci_dev see the correct PCI device. E.g. the s390
and powerpc DMA mapping operations use to_pci_dev() even with I/O
MMU support disabled.

This patch preserves the following changes of the DMA mapping updates
patch series:
- Introduction of dma_virt_ops.
- Removal of ib_device.dma_ops.
- Removal of struct ib_dma_mapping_ops.
- Removal of an if-statement from each ib_dma_*() operation.
- IB HW drivers no longer set dma_device directly.

c103b4dac8 nbd: set rq->errors to actual error code
We've been relying on the block layer to assume rq->errors being set
translates into -EIO.  I noticed in testing that sometimes this isn't
true, and really there's not much of a reason to have a counter instead
of just using -EIO.  So set it properly so we don't leak random numbers
to unsuspecting victims.

9dd5d3ab49 nbd: handle ERESTARTSYS properly
We can submit IO in a processes context, which means there can be
pending signals.  This isn't a fatal error for NBD, but it does require
some finesse.  If the signal happens before we transmit anything then we
are ok, just requeue the request and carry on.  However if we've done a
partial transmit we can't allow anything else to be transmitted on this
socket until we transmit the remaining part of the request.  Deal with
this by keeping track of how much we've sent for the current request,
and if we get an ERESTARTSYS during any part of our transmission save
the state of that request and requeue the IO.  If anybody tries to
submit a request that isn't our pending request then requeue that
request until we are able to service the one that is pending.

successfully, but we really want to return whether or not the we made
progress. Progress includes if we got an error return.  If we don't,
this can lead to a hang in blk_mq_sched_dispatch_requests() when a
driver is draining IO by returning BLK_MQ_QUEUE_ERROR instead of
manually ending the IO in error and return BLK_MQ_QUEUE_OK.

 "There's a kaslr fix and then two patches to update our native and

  to the asm-generic unistd.h via arm64, as he didn't have anything
  queued in the asm-generic tree.

  Summary:

   - Fix mapping of kernel image under certain kaslr offsets

   - Hook up new statx syscall in asm-generic syscall table

   - Update compat syscall table to match arch/arm/ (pkeys and statx)"

cb88645596 infiniband: Fix alignment of mmap cookies to support VIPT caching
When vmalloc_user is used to create memory that is supposed to be mmap'd
to user space, it is necessary for the mmap cookie (eg the offset) to be
aligned to SHMLBA.

This creates a situation where all virtual mappings of the same physical
page share the same virtual cache index and guarantees VIPT coherence.
Otherwise the cache is non-coherent and the kernel will not see writes
by userspace when reading the shared page (or vice-versa).

cancel_work_sync protects against self-requeue of the

871a8623d3 i40iw: Receive netdev events post INET_NOTIFIER state
Netdev notification events are de-registered only when all
client iwdev instances are removed. If a single client is closed
and re-opened, netdev events could arrive even before the Control
Queue-Pair (CQP) is created, causing a NULL pointer dereference crash
in i40iw_get_cqp_request. Fix this by allowing netdev event
notification only after we have reached the INET_NOTIFIER state with
respect to device initialization.

ebe64824e9 Power management fixes for v4.11-rc4
- Make intel_pstate use one set of global P-state limits in the
    active mode regardless of the scaling_governor settings for
    individual CPUs instead of switching back and forth between two
    of them in a way that is hard to control (Rafael Wysocki).
 
  - Drop a useless function from intel_pstate to prevent it from
    modifying the maximum supported frequency value unexpectedly
    which may confuse the cpufreq core (Rafael Wysocki).
 
  - Fix the cpufreq core to restore policy limits on CPU online so
    that the limits are not reset over system suspend/resume, among
    other things (Viresh Kumar).
 
  - Fix the initialization of the schedutil cpufreq governor to
    make the IO-wait boosting mechanism in it actually work on
    systems with one CPU per cpufreq policy (Rafael Wysocki).
 
  - Add a sanity check to the cpuidle core to prevent crashes from
    happening if the architecture code initialization fails to set
    up things as expected (Vaidyanathan Srinivasan).

Merge tag 'pm-4.11-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull power management fixes from Rafael Wysocki:
 "One of these is an intel_pstate regression fix and it is not a small
  change, but it mostly removes code that shouldn't be there. That code
  was acquired by mistake and has been a source of constant pain since
  then, so the time has come to get rid of it finally. We have not seen
  problems with this change in the lab, so fingers crossed.

  The rest is more usual: one more intel_pstate commit removing useless
  code, a cpufreq core fix to make it restore policy limits on CPU
  online (which prevents the limits from being reset over system
  suspend/resume), a schedutil cpufreq governor initialization fix to
  make it actually work as advertised on all systems and an extra sanity
  check in the cpuidle core to prevent crashes from happening if the
  arch code messes things up.

  Specifics:

   - Make intel_pstate use one set of global P-state limits in the
     active mode regardless of the scaling_governor settings for
     individual CPUs instead of switching back and forth between two of
     them in a way that is hard to control (Rafael Wysocki).

   - Drop a useless function from intel_pstate to prevent it from
     modifying the maximum supported frequency value unexpectedly which
     may confuse the cpufreq core (Rafael Wysocki).

   - Fix the cpufreq core to restore policy limits on CPU online so that
     the limits are not reset over system suspend/resume, among other
     things (Viresh Kumar).

   - Fix the initialization of the schedutil cpufreq governor to make
     the IO-wait boosting mechanism in it actually work on systems with
     one CPU per cpufreq policy (Rafael Wysocki).

   - Add a sanity check to the cpuidle core to prevent crashes from
     happening if the architecture code initialization fails to set up
     things as expected (Vaidyanathan Srinivasan)"

A few fixes for a bunch of clocks on a few SoCs. The most important one is
 probably one that fixes the NKMP clock frequency calculation and could end
 up with clocking the CPU frequency to out of bounds rates.

a2125d0244 hwmon: (asus_atk0110) fix uninitialized data access
The latest gcc-7 snapshot adds a warning to point out that when
atk_read_value_old or atk_read_value_new fails, we copy
uninitialized data into sensor->cached_value:

drivers/hwmon/asus_atk0110.c: In function 'atk_input_show':
drivers/hwmon/asus_atk0110.c:651:26: error: 'value' may be used uninitialized in this function [-Werror=maybe-uninitialized]

Adding an error check avoids this. All versions of the driver
are affected.
