Make the map match the reality, the current binding text is
nonsense:

- The clock required for the clocking of the serial port
  must come first and is not optional (as the driver will
  otherwise proceed to grab and use the apb_pclk as uartclk),
  and the apb_pclk that clocks the logic must come second
  as the code will retrieve the first clock by index,
  whereas the PrimeCell but will explicitly look for
  "apb_pclk" so this can be specified later, as it is
  looked up by name.

- The pin control state "default" is the only mandated
  state, the sleep state is entirely optional.

We also add an example to avoid further confusion.

Overlays are a method to dynamically modify part of the kernel's
device tree with dynamically loaded data. Add the core functionality to
parse, apply and remove an overlay changeset. The core functionality
takes care of managing the overlay data format and performing the add
and remove. Drivers are expected to use the overlay functionality to
support custom expansion busses commonly found on consumer development
boards like the BeagleBone or Raspberry Pi.

The overlay code uses CONFIG_OF_DYNAMIC changesets to perform the low
level work of modifying the devicetree.

Documentation about internal and APIs is provided in
	Documentation/devicetree/overlay-notes.txt

v2:
- Switch from __of_node_alloc() to __of_node_dup()
- Documentation fixups
- Remove 2-pass processing of properties
- Remove separate ov_lock; just use the DT mutex.

- Drop delete capability using '-' prefix. The '-' prefixed names
are valid properties and nodes and there is no need for it just yet.
- Do not update special properties - name & phandle ones.

Chris bisected a NULL pointer deference in task_sched_runtime() to
commit 6e998916 'sched/cputime: Fix clock_nanosleep()/clock_gettime()
inconsistency'.

Chris observed crashes in atop or other /proc walking programs when he
started fork bombs on his machine.  He assumed that this is a new exit
race, but that does not make any sense when looking at that commit.

What's interesting is that, the commit provides update_curr callbacks
for all scheduling classes except stop_task and idle_task.

While nothing can ever hit that via the clock_nanosleep() and
clock_gettime() interfaces, which have been the target of the commit in
question, the author obviously forgot that there are other code paths
which invoke task_sched_runtime()

do_task_stat(()
 thread_group_cputime_adjusted()
   thread_group_cputime()
     task_cputime()
       task_sched_runtime()
        if (task_current(rq, p) && task_on_rq_queued(p)) {
          update_rq_clock(rq);
          up->sched_class->update_curr(rq);
        }

If the stats are read for a stomp machine task, aka 'migration/N' and
that task is current on its cpu, this will happily call the NULL pointer
of stop_task->update_curr.  Ooops.

Chris observation that this happens faster when he runs the fork bomb
makes sense as the fork bomb will kick migration threads more often so
the probability to hit the issue will increase.

Add the missing update_curr callbacks to the scheduler classes stop_task
and idle_task.  While idle tasks cannot be monitored via /proc we have
other means to hit the idle case.

Merge x86-64 iret fixes from Andy Lutomirski:
 "This addresses the following issues:

   - an unrecoverable double-fault triggerable with modify_ldt.
   - invalid stack usage in espfix64 failed IRET recovery from IST
     context.
   - invalid stack usage in non-espfix64 failed IRET recovery from IST
     context.

  It also makes a good but IMO scary change: non-espfix64 failed IRET
  will now report the correct error.  Hopefully nothing depended on the
  old incorrect behavior, but maybe Wine will get confused in some
  obscure corner case"

* emailed patches from Andy Lutomirski <luto@amacapital.net>:
  x86_64, traps: Rework bad_iret
  x86_64, traps: Stop using IST for #SS
  x86_64, traps: Fix the espfix64 #DF fixup and rewrite it in C

It's possible for iretq to userspace to fail.  This can happen because
of a bad CS, SS, or RIP.

Historically, we've handled it by fixing up an exception from iretq to
land at bad_iret, which pretends that the failed iret frame was really
the hardware part of #GP(0) from userspace.  To make this work, there's
an extra fixup to fudge the gs base into a usable state.

This is suboptimal because it loses the original exception.  It's also
buggy because there's no guarantee that we were on the kernel stack to
begin with.  For example, if the failing iret happened on return from an
NMI, then we'll end up executing general_protection on the NMI stack.
This is bad for several reasons, the most immediate of which is that
general_protection, as a non-paranoid idtentry, will try to deliver
signals and/or schedule from the wrong stack.

This patch throws out bad_iret entirely.  As a replacement, it augments
the existing swapgs fudge into a full-blown iret fixup, mostly written
in C.  It's should be clearer and more correct.

On a 32-bit kernel, this has no effect, since there are no IST stacks.

On a 64-bit kernel, #SS can only happen in user code, on a failed iret
to user space, a canonical violation on access via RSP or RBP, or a
genuine stack segment violation in 32-bit kernel code.  The first two
cases don't need IST, and the latter two cases are unlikely fatal bugs,
and promoting them to double faults would be fine.

This fixes a bug in which the espfix64 code mishandles a stack segment
violation.

This saves 4k of memory per CPU and a tiny bit of code.

While decoupling ATOMIC and DEAD flags, f47ad457 ("percpu_ref:

__ref_is_percpu() so that it only tests ATOMIC flag to determine
whether the ref is in percpu mode or not; however, while DEAD implies
ATOMIC, the two flags are set separately during percpu_ref_kill() and
if __ref_is_percpu() races percpu_ref_kill(), it may see DEAD w/o
ATOMIC.  Because __ref_is_percpu() returns @ref->percpu_count_ptr
value verbatim as the percpu pointer after testing ATOMIC, the pointer
may now be contaminated with the DEAD flag.

This can be fixed by clearing the flag bits before returning the
pointer which was the fix proposed by Shaohua; however, as DEAD
implies ATOMIC, we can just test for both flags at once and avoid the
explicit masking.

Update __ref_is_percpu() so that it tests that both ATOMIC and DEAD
are clear before returning @ref->percpu_count_ptr as the percpu

Pull SCSI target fixes from Nicholas Bellinger:
 "Here are the target-pending fixes queued for v3.18-rc6.

  The highlights include:

   - target-core OOPs fix with tcm_qla2xxx + vxworks FC initiators +
     zero length SCSI commands having a transfer direction set.  (Roland
     + Craig Watson)

   - vhost-scsi OOPs fix to explicitly prevent WWPN endpoint configfs
     group removal while qemu still has an active reference.  (Paolo +
     nab)

   - ib_srpt fix for RDMA hardware with lower srp_sq_size limits.
     (Bart)

   - two ib_isert work-arounds for running on ocrdma hardware (Or + Sagi
     + Chris)

   - iscsi-target discovery portal typo + SPC-3 PR Preempt SA key
     matching fix (Steve)"

* git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending:
  IB/isert: Adjust CQ size to HW limits
  target: return CONFLICT only when SA key unmatched
  iser-target: Handle DEVICE_REMOVAL event on network portal listener correctly
  ib_isert: Add max_send_sge=2 minimum for control PDU responses
  srp-target: Retry when QP creation fails with ENOMEM
  iscsi-target: return the correct port in SendTargets
  vhost-scsi: Take configfs group dependency during VHOST_SCSI_SET_ENDPOINT
  target: Don't call TFO->write_pending if data_length == 0

Pull dmaengine fixes from Vinod Koul:
 "We have couple of fixes for dmaengine queued up:
   - dma mempcy fix for dma configuration of sun6i by Maxime
   - pl330 fixes: First the fixing allocation for data buffers by Liviu
     and then Jon's fixe for fifo width and usage"

* 'fixes' of git://git.infradead.org/users/vkoul/slave-dma:
  dmaengine: Fix allocation size for PL330 data buffer depth.
  dmaengine: pl330: Limit MFIFO usage for memcpy to avoid exhausting entries
  dmaengine: pl330: Align DMA memcpy operations to MFIFO width
  dmaengine: sun6i: Fix memcpy operation
