Netfilter updates for net-next
The following patchset contains Netfilter updates for net-next:
1) Add nft_reg_store64() and nft_reg_load64() helpers, from Ander Juaristi.
2) Time matching support, also from Ander Juaristi.
3) VLAN support for nfnetlink_log, from Michael Braun.
4) Support for set element deletions from the packet path, also from Ander.
5) Remove __read_mostly from conntrack spinlock, from Li RongQing.
6) Support for updating stateful objects, this also includes the initial
client for this infrastructure: the quota extension. A follow up fix
for the control plane also comes in this batch. Patches from
Fernando Fernandez Mancera.

We 'allocate' 'count' bytes here. In fact, 'dev_alloc_skb' already add some
extra space for padding, so a bit more is allocated.
However, we use 1 byte for the KISS command, then copy 'count' bytes, so
count+1 bytes.
Explicitly allocate and use 1 more byte to be safe.

====================
100GbE Intel Wired LAN Driver Updates 2019-09-05
This series contains updates to ice driver.
Brett fixes the setting of num_q_vectors by using the maximum number
between the allocated transmit and receive queues.
Anirudh simplifies the code to use a helper function to return the main
VSI, which is the first element in the pf->vsi array. Adds a pointer
check to prevent a NULL pointer dereference. Adds a check to ensure we
do not initialize DCB on devices that are not DCB capable. Does some
housekeeping on the code to remove unnecessary indirection and reduce
the PF structure by removing elements that are not needed since the
values they were storing can be readily gotten from
ice_get_avail_*_count()'s. Updates the printed strings to make it
easier to search the logs for driver capabilities.
Jesse cleans up unnecessary function arguments. Updated the code to use
prefetch() to add some efficiency to the driver to avoid a cache miss.
Did some housekeeping on the code to remove the configurable transmit
work limit via ethtool which ended up creating performance overhead.
Made additional performance enhancements by updating the driver to start
out with a reasonable number of descriptors by changing the default to
2048.
Mitch fixes the reset logic for VFs by clearing VF_MBX_ARQLEN register
when the source of the reset is not PFR.
Lukasz updates the driver to include a similar fix for the i40e driver
by reporting link down for VF's when the PF queues are not enabled.
Akeem updates the driver to report the VF link status once we get VF
resources so that we can reflect the link status similarly to how the PF
reports link speed.
Ashish updates the transmit context structure based on recent changes to
the hardware specification.
Dave updates the DCB logic to allow a delayed registration for MIB
change events so that the driver is not accepting events before it is
ready for them.

The destructor of AMDTP domain has WARN_ON() for the list of associated
AMDTP stream. Although this reminds a case that developers forget to
program consumer drivers to stop AMDTP domain, it hits when AMDTP domain
is not initialized yet. This occurs when initialization of sound card
fails as well and it's superfluous.
This commit removes the WARN_ON. Although the API to AMDTP domain does
nothing, it's left for future usage.

As Vincent noticed, the y2038 conversion of semtimedop in linux-5.1
broke when commit 00bf25d693e7 ("y2038: use time32 syscall names on
32-bit") changed all system calls on all architectures that take
a 32-bit time_t to point to the _time32 implementation, but left out
semtimedop in the asm-generic header.
This affects all 32-bit architectures using asm-generic/unistd.h:
h8300, unicore32, openrisc, nios2, hexagon, c6x, arc, nds32 and csky.
The notable exception is riscv32, which has dropped support for the
time32 system calls entirely.

The reference driver no longer exists since commit 50f1242c6742 ("mtd:
fsl-quadspi: Remove the driver as it was replaced by spi-fsl-qspi.c").
Update reference to spi-fsl-qspi.c driver.

====================
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) Add the ability to use unaligned chunks in the AF_XDP umem. By
relaxing where the chunks can be placed, it allows to use an
arbitrary buffer size and place whenever there is a free
address in the umem. Helps more seamless DPDK AF_XDP driver
integration. Support for i40e, ixgbe and mlx5e, from Kevin and
Maxim.
2) Addition of a wakeup flag for AF_XDP tx and fill rings so the
application can wake up the kernel for rx/tx processing which
avoids busy-spinning of the latter, useful when app and driver
is located on the same core. Support for i40e, ixgbe and mlx5e,
from Magnus and Maxim.
3) bpftool fixes for printf()-like functions so compiler can actually
enforce checks, bpftool build system improvements for custom output
directories, and addition of 'bpftool map freeze' command, from Quentin.
4) Support attaching/detaching XDP programs from 'bpftool net' command,
from Daniel.
5) Automatic xskmap cleanup when AF_XDP socket is released, and several
barrier/{read,write}_once fixes in AF_XDP code, from Björn.
6) Relicense of bpf_helpers.h/bpf_endian.h for future libbpf
inclusion as well as libbpf versioning improvements, from Andrii.
7) Several new BPF kselftests for verifier precision tracking, from Alexei.
8) Several BPF kselftest fixes wrt endianess to run on s390x, from Ilya.
9) And more BPF kselftest improvements all over the place, from Stanislav.
10) Add simple BPF map op cache for nfp driver to batch dumps, from Jakub.
11) AF_XDP socket umem mapping improvements for 32bit archs, from Ivan.
12) Add BPF-to-BPF call and BTF line info support for s390x JIT, from Yauheni.
13) Small optimization in arm64 JIT to spare 1 insns for BPF_MOD, from Jerin.
14) Fix an error check in bpf_tcp_gen_syncookie() helper, from Petar.
15) Various minor fixes and cleanups, from Nathan, Masahiro, Masanari,
Peter, Wei, Yue.
