Rob Herring 6b22b3d161 kbuild: Allow using host dtc instead of kernel's copy
Development of dtc happens in its own upstream repository, but testing
dtc changes against the kernel tree is useful. Change dtc to a variable
that users can override.

Amitoj Kaur Chawla 82f68756e9 of: resolver: Add missing of_node_get and of_node_put
In __of_find_node_by_full_name, add an of_node_get when detecting the
desired element, to ensure that it ends up with a reference count that is
one greater than on entering the function.

Also in __of_find_node_by_full_name, add an of_node_put on breaking
out of the for_each_child_of_node loop, to ensure that the reference
count of the returned value is not double incremented. This change
was made using Coccinelle.

The semantic patch used for this is as follows:

// <smpl>
@@
expression e;
local idexpression n;
@@

 for_each_child_of_node(..., n) {
   ... when != of_node_put(n)
       when != e = n
(
   return n;
|
+  of_node_put(n);
?  return ...;
)
   ...
 }
// </smpl

Finally, add an of_node_put in for_each_child_of_node in the function
__of_adjust_phandle_ref after the value returned by
__of_find_node_by_full_name is no longer useful.

Rob Herring bde7fabad9 dt/bindings: add documentation on standard property unit suffixes
A common review comment is to add units to DT property names. The naming
convention is inconsistent unfortunately although there are clear
majorities in use already. This makes it hard to remember the exact name
preferred, so I'm documenting this to provide an easy point of
reference.

Frank Rowand 10eadc253d dtc: create tool to diff device trees
Create script to diff device trees.

The device tree can be in any of the forms recognized by the dtc compiler:
  - source
  - binary blob
  - file system tree (from /proc/devicetree)

If the device tree is a source file, then it is pre-processed in the
same way as it would be when built in the linux kernel source tree
before diffing.

     startup.

Christoph Lameter 587198ba52 vmstat: Remove BUG_ON from vmstat_update
If we detect that there is nothing to do just set the flag and do not
check if it was already set before.  Races really do not matter.  If the
flag is set by any code then the shepherd will start dealing with the
situation and reenable the vmstat workers when necessary again.

Since commit 0eb77e9880 ("vmstat: make vmstat_updater deferrable again
and shut down on idle") quiet_vmstat might update cpu_stat_off and mark
a particular cpu to be handled by vmstat_shepherd.  This might trigger a
VM_BUG_ON in vmstat_update because the work item might have been
sleeping during the idle period and see the cpu_stat_off updated after
the wake up.  The VM_BUG_ON is therefore misleading and no more
appropriate.  Moreover it doesn't really suite any protection from real
bugs because vmstat_shepherd will simply reschedule the vmstat_work
anytime it sees a particular cpu set or vmstat_update would do the same
from the worker context directly.  Even when the two would race the
result wouldn't be incorrect as the counters update is fully idempotent.

The header arch/mips/kvm/opcode.h defines a few extra opcodes which
aren't in arch/mips/include/uapi/asm/inst.h. There's nothing KVM
specific about them, so lets move them into inst.h where they belong and
delete the header.

Note that mfmcz_op is renamed to mfmc0_op to match the instruction set
manual, and wait_op was already added to inst.h in commit b0a3eae2b9
("MIPS: inst.h: define COP0 wait op"), merged in v3.16-rc1.

Most of the cache op codes defined in cacheops.h are split into a 2-bit
cache identifier, and a 3-bit cache op code which does largely the same
thing semantically regardless of the cache identifier.

To allow the use of these definitions by KVM for decoding cache ops,
break the definitions down into parts where it makes sense to do so, and
add masks for the Cache and Op field within the cache op.

This adds support for the interrupt controller present on PIC32 class

exists outside of the CPU core and is the arbitrator of all interrupts
(including interrupts from the CPU itself) before they are presented to
the CPU.

The following features are supported:
 - DT properties for EVIC and for devices/peripherals that use interrupt lines
 - Persistent and non-persistent interrupt handling
 - irqdomain and generic chip support
 - Configuration of external interrupt edge polarity
