47adf2f4f5 IB/uverbs: Expose RSS related capabilities
Query RSS related attributes and return them to user-space via the
extended query device uverbs command.

It includes both direct ones (i.e. struct ib_uverbs_rss_caps) and
max_wq_type_rq which may be used in both RSS and non RSS flows.

ccf2056260 IB/core: Expose RSS related capabilities
Expose RSS related capabilities, it includes both direct ones (i.e.
struct ib_rss_caps) and max_wq_type_rq which may be used in both
RSS and non RSS flows.

Specifically,
supported_qpts:
- QP types that support RSS on the device.

max_rwq_indirection_tables:
- Max number of receive work queue indirection tables that
  could be opened on the device.

max_rwq_indirection_table_size:
- Max size of a receive work queue indirection table.

max_wq_type_rq:
- Max number of work queues of receive type that
  could be opened on the device.

35d04077ad metag: Only define atomic_dec_if_positive conditionally
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.

bc75450cc3 Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid
Pull HID updates from Jiri Kosina:

 - 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

 - ... a lot of other assorted small fixes and device ID additions

29ae7f9dc2 NFSD: Implement the COPY call

This update includes the usual round of major driver updates (hpsa, be2iscsi,
 hisi_sas, zfcp, cxlflash).  There's a new incarnation of hpsa called smartpqi
 for which a driver is added, there's some cleanup work of the ibm vscsi target
 and updates to libfc, plus a whole host of minor fixes and updates and finally
 the removal of several ISA drivers which seem not to have been used for years.

690d097c00 parisc: Increase KERNEL_INITIAL_SIZE for 32-bit SMP kernels
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.

c969e24c1b libnvdimm, namespace: filter out of range labels in scan_labels()
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.

762d067dba libnvdimm, namespace: enable allocation of multiple pmem namespaces
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).

16660eaea0 libnvdimm, namespace: update label implementation for multi-pmem
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.

a1f3e4d6a0 libnvdimm, region: update nd_region_available_dpa() for multi-pmem support
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.

2a51fe083e arch/x86: Handle non enumerated CPU after physical hotplug
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.

Merge tag 'rxrpc-rewrite-20161004' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs

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.

d35c99ff77 netlink: do not enter direct reclaim from netlink_dump()
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)

6664498280 packet: call fanout_release, while UNREGISTERING a netdev
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.
