22dccc5454 IB/rdmavt: Only put mmap_info ref if it exists
rvt_create_qp() creates qp->ip only when a qp creation request comes from
userspace (udata is not NULL).  If we exceed the number of available
queue pairs however, the error path always attempts to put a kref to this
structure.  If the requestor is inside the kernel, this leads to a crash.

We fix this by checking that qp->ip is not NULL before caling kref_put().

f5eabf5e51 IB/rdmavt: Handle the kthread worker using the new API
Use the new API to create and destroy the cq kthread worker.
The API hides some implementation details.

In particular, kthread_create_worker() allocates and initializes
struct kthread_worker. It runs the kthread the right way and stores
task_struct into the worker structure. In addition, the *on_cpu()
variant binds the kthread to the given cpu and the related memory
node.

kthread_destroy_worker() flushes all pending works, stops
the kthread and frees the structure.

This patch does not change the existing behavior. Note that we must
use the on_cpu() variant because the function starts the kthread
and it must bind it to the right CPU before waking. The numa node
is associated for given CPU as well.

6efaf10f16 IB/rdmavt: Avoid queuing work into a destroyed cq kthread worker
The memory barrier is not enough to protect queuing works into
a destroyed cq kthread. Just imagine the following situation:

CPU1				CPU2

rvt_cq_enter()
  worker =  cq->rdi->worker;

				rvt_cq_exit()
				  rdi->worker = NULL;
				  smp_wmb();
				  kthread_flush_worker(worker);
				  kthread_stop(worker->task);
				  kfree(worker);

				  // nothing queued yet =>
				  // nothing flushed and
				  // happily stopped and freed

  if (likely(worker)) {
     // true => read before CPU2 acted
     cq->notify = RVT_CQ_NONE;
     cq->triggered++;
     kthread_queue_work(worker, &cq->comptask);

  BANG: worker has been flushed/stopped/freed in the meantime.

This patch solves this by protecting the critical sections by
rdi->n_cqs_lock. It seems that this lock is not much contended
and looks reasonable for this purpose.

One catch is that rvt_cq_enter() might be called from IRQ context.
Therefore we must always take the lock with IRQs disabled to avoid
a possible deadlock.

66431b0e86 IB/hfi1: Define platform_config_table_limits once
Defining static data structures in a header file is wrong because
this causes the data structure to be instantiated once in every .c
file it is included in. Hence move the definition of a static
array from a header file into the only .c file in which it is used.

b777f154a0 IB/hfi1: Remove usage of qp->s_cur_sge
The s_cur_sge field in the qp structure holds a pointer to the
SGE of the currently processed WQE. It assumes the protection
of the RVT_S_BUSY flag to prevent the changing of this field
while the send engine is using it. This scheme works as long
as there is only one instance of the send engine running at a
time.

Scaling of the send engine to multiple cores would break this
assumption as there could be multiple instances of the send engine
running on different CPUs. This opens a window where the QP's
RVT_S_BUSY flag is not set but the send engine is still running.

To prevent accidental changing of the s_cur_sge pointer, the QP's
dependence on it is removed. The SGE pointer is now stored in the
verbs_txreq, which is a per-packet data structure. This ensures
that each individual packet has it's own pointer, which is setup
while the RVT_S_BUSY flag is set.

4e045572e2 IB/hfi1: Add unique txwait_lock for txreq events
Profiling suggests that the read_seqbegin() in
the txreq put logic is colliding with other uses
of the iowait lock.

The packet at a time use of this lock dictates a unique
lock to avoid reader/writer collisions when the number
of vTxWait events is low.

In order to support a unique lock the iowait struct embedded
in the QP is extended to remember the lock that protects the queue
head.

The QP destroy removes that QP from any wait list.  It doesn't
need to know the head because of the linked list API, but it does
need to know the lock required to protect the head.

This also opens up the wait logic to have unique per resources locks
which needs to be in future refinement.

42fd2b5006 Merge branch 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 bugfix from Thomas Gleixner:
 "A single bugfix for the recent changes related to registering the boot
  cpu when this has not happened before prefill_possible_map().

  The main problem with this change got fixed already, but we missed the
  case where the local APIC is not yet mapped, when prefill_possible_map()
  is invoked, so the registration of the boot cpu which has the APIC bit
  set in CPUID will explode.

  I should have seen that issue earlier, but all I can do now is feeling
  embarassed"

2674235fd4 ARM: SoC fixes
We haven't seen a whole lot of fixes for the first two weeks since the merge
 window, but here is the batch that we have at the moment.
 
 Nothing sticks out as particularly bad or scary, it's mostly a handful of
 smaller fixes to several platforms. The Uniphier reset controller changes
 could probably have been delayed to 4.10, but they're not scary and just
 plumbing up driver changes that went in during the merge window.
 
 We're also adding another maintainer to Marvell Berlin platforms, to help
 out when Sebastian is too busy. Yay teamwork!

37cc6bb8f2 tty/serial driver fixes for 4.9-rc3
Here are a number of small tty and serial driver fixes for reported
 issues for 4.9-rc3.  Nothing major, but they do resolve a bunch of
 problems with the tty core changes that are in 4.9-rc1, and finally the
 atmel serial driver is back working properly.
 
 All have been in linux-next with no reported issues.
