The definition of atomic_dec_if_positive() assumes that
atomic_sub_if_positive() exists, which is only the case if
metag specific atomics are used. This results in the following
build error when trying to build metag1_defconfig.
kernel/ucount.c: In function 'dec_ucount':
kernel/ucount.c:211: error:
implicit declaration of function 'atomic_sub_if_positive'
Moving the definition of atomic_dec_if_positive() into the metag
conditional code fixes the problem.

- Integrated Sensor Hub support (Cherrytrail+) from Srinivas Pandruvada
- Big cleanup of Wacom driver; namely it's now using devres, and the
standardized LED API so that libinput doesn't need to have root
access any more, with substantial amount of other cleanups
piggy-backing on top. All this from Benjamin Tissoires
- Report descriptor parsing would now ignore and out-of-range System
controls in case of the application actually being System Control.
This fixes quite some issues with several devices, and allows us to
remove a few ->report_fixup callbacks. From Benjamin Tissoires

Increase the initial kernel default page mapping size for SMP kernels to 32MB
and add a runtime check which panics early if the kernel is bigger than the
initial mapping size.
This fixes boot crashes of 32bit SMP kernels. Due to the introduction of huge
page support in kernel 4.4 and it's required initial kernel layout in memory, a
32bit SMP kernel usually got bigger (in layout, not size) than 16MB.

Short-circuit doomed-to-fail label validation attempts by skipping
labels that are outside the given region. For example a DIMM that has
multiple PMEM regions will waste time attempting to create namespaces
only to find that the interleave-set-cookie does not validate, e.g.:
nd_region region6: invalid cookie in label: 73e608dc-47b9-4b2a-b5c7-2d55a32e0c2
Similar to how we skip BLK labels when performing PMEM validation we can
skip out-of-range labels early.

Now that we have nd_region_available_dpa() able to handle the presence
of multiple PMEM allocations in aliased PMEM regions, reuse that same
infrastructure to track allocations from free space. In particular
handle allocating from an aliased PMEM region in the case where there
are dis-contiguous holes. The allocation for BLK and PMEM are
documented in the space_valid() helper:
BLK-space is valid as long as it does not precede a PMEM
allocation in a given region. PMEM-space must be contiguous
and adjacent to an existing existing allocation (if one
exists).

Instead of assuming that there will only ever be one allocated range at
the start of the region, account for additional namespaces that might
start at an offset from the region base.
After this change pmem namespaces now have a reason to carry an array of
resources similar to blk. Unifying the resource tracking infrastructure
in nd_namespace_common is a future cleanup candidate.

The free dpa (dimm-physical-address) space calculation reports how much
free space is available with consideration for aliased BLK + PMEM
regions. Recall that BLK capacity is allocated from high addresses and
PMEM is allocated from low addresses in their respective regions.
nd_region_available_dpa() accounts for the fact that the largest
encroachment (lowest starting address) into PMEM capacity by a BLK
allocation limits the available capacity to that point, regardless if
there is BLK allocation hole at a higher address. Similarly, for the
multi-pmem case we need to track the largest encroachment (highest
ending address) of a PMEM allocation in BLK capacity regardless of
whether there is an allocation hole that a BLK allocation could fill at
a lower address.

When a CPU is physically added to a system then the MADT table is not
updated.
If subsequently a kdump kernel is started on that physically added CPU then
the ACPI enumeration fails to provide the information for this CPU which is
now the boot CPU of the kdump kernel.
As a consequence, generic_processor_info() is not invoked for that CPU so
the number of enumerated processors is 0 and none of the initializations,
including the logical package id management, are performed.
We have code which relies on the correctness of the logical package map and
other information which is initialized via generic_processor_info().
Executing such code will result in undefined behaviour or kernel crashes.
This problem applies only to the kdump kernel because a normal kexec will
switch to the original boot CPU, which is enumerated in MADT, before
jumping into the kexec kernel.
The boot code already has a check for num_processors equal 0 in
prefill_possible_map(). We can use that check as an indicator that the
enumeration of the boot CPU did not happen and invoke generic_processor_info()
for it. That initializes the relevant data for the boot CPU and therefore
prevents subsequent failure.

When CONFIG_JFFS2_FS_XATTR is off, jffs2_xattr_handlers is defined as
NULL. With sb->s_xattr == NULL, the generic_{get,set,remove}xattr
functions produce the same result as setting the {get,set,remove}xattr
inode operations to NULL, so there is no need for these macros.

David Howells says:
====================
rxrpc: Fixes
This set of patches contains a bunch of fixes:
(1) Fix an oops on incoming call to a local endpoint without a bound
service.
(2) Only ping for a lost reply in a client call (this is inapplicable to
service calls).
(3) Fix maybe uninitialised variable warnings in the ACK/ABORT sending
function by splitting it.
(4) Fix loss of PING RESPONSE ACKs due to them being subsumed by PING ACK
generation.
(5) OpenAFS improperly terminates calls it makes as a client under some
circumstances by not fully hard-ACK'ing the last DATA packets. This
is alleviated by a new call appearing on the same channel implicitly
completing the previous call on that channel. Handle this implicit
completion.
(6) Properly handle expiry of service calls due to the aforementioned
improper termination with no follow up call to implicitly complete it:
(a) The call's background processor needs to be queued to complete the
call, send an abort and notify the socket.
(b) The call's background processor needs to notify the socket (or the
kernel service) when it has completed the call.
(c) A negative error code must thence be returned to the kernel
service so that it knows the call died.
(d) The AFS filesystem must detect the fatal error and end the call.
(7) Must produce a DELAY ACK when the actual service operation takes a
while to process and must cancel the ACK when the reply is ready.
(8) Don't request an ACK on the last DATA packet of the Tx phase as this
confuses OpenAFS.

Since linux-3.15, netlink_dump() can use up to 16384 bytes skb
allocations.
Due to struct skb_shared_info ~320 bytes overhead, we end up using
order-3 (on x86) page allocations, that might trigger direct reclaim and
add stress.
The intent was really to attempt a large allocation but immediately
fallback to a smaller one (order-1 on x86) in case of memory stress.
On recent kernels (linux-4.4), we can remove __GFP_DIRECT_RECLAIM to
meet the goal. Old kernels would need to remove __GFP_WAIT
While we are at it, since we do an order-3 allocation, allow to use
all the allocated bytes instead of 16384 to reduce syscalls during
large dumps.
iproute2 already uses 32KB recvmsg() buffer sizes.
Alexei provided an initial patch downsizing to SKB_WITH_OVERHEAD(16384)

If a socket has FANOUT sockopt set, a new proto_hook is registered
as part of fanout_add(). When processing a NETDEV_UNREGISTER event in
af_packet, __fanout_unlink is called for all sockets, but prot_hook which was
registered as part of fanout_add is not removed. Call fanout_release, on a
NETDEV_UNREGISTER, which removes prot_hook and removes fanout from the
fanout_list.
This fixes BUG_ON(!list_empty(&dev->ptype_specific)) in netdev_run_todo()

The KSZ9031 skew registers contain an offset, the chip's default value
is "neutral" which does not add any skew. Programming a 0 into a skew
property will actually set it the maximal negative adjustment and not
to a neutral position as one would expect.
Explain this situation in the devicetree binding documentation and list
the settings that the chip considers neutral.
Changing the implementation to accept negative values would have been
a better solution, but would break existing configurations.
