      Pull MTD updates from Brian Norris:
       "General updates:
         - Cleanups and additional flash support for "dataflash" driver
         - new driver for mchp23k256 SPI SRAM device
         - improve handling of MTDs without eraseblocks (i.e., MTD_NO_ERASE)
         - refactor and improve "sub-partition" handling with TRX partition
           parser; partitions can now be created as sub-partitions of another
           partition
      
        SPINOR updates, from Cyrille Pitchen and Marek Vasut:
         - introduce support to the SPI 1-2-2 and 1-4-4 protocols.
         - introduce support to the Double Data Rate (DDR) mode.
         - introduce support to the Octo SPI protocols.
         - add support to new memory parts for Spansion, Macronix and Winbond.
         - add fixes for the Aspeed, STM32 and Cadence QSPI controler drivers.
         - clean up the st_spi_fsm driver.
      
        NAND updates, from Boris Brezillon:
         - addition of on-die ECC support to Micron driver
         - addition of helpers to help drivers choose most appropriate ECC
           settings
         - deletion of dead-code (cached programming and ->errstat() hook)
         - make sure drivers that do not support the SET/GET FEATURES command
           return ENOTSUPP use a dummy ->set/get_features implementation
           returning -ENOTSUPP (required for Micron on-die ECC)
         - change the semantic of ecc->write_page() for drivers setting the
           NAND_ECC_CUSTOM_PAGE_ACCESS flag
         - support exiting 'GET STATUS' command in default ->cmdfunc()
           implementations
         - change the prototype of ->setup_data_interface()
      
        A bunch of driver related changes:
         - various cleanup, fixes and improvements of the MTK driver
         - OMAP DT bindings fixes
         - support for ->setup_data_interface() in the fsmc driver
         - support for imx7 in the gpmi driver
         - finalization of the denali driver rework (thanks to Masahiro for
           the work he's done on this driver)
         - fix "bitflips in erased pages" handling in the ifc driver
         - addition of PM ops and dynamic timing configuration to the atmel
           driver"

       "i915, amd and some core fixes + mediatek color support.
      
        Some fixes tree came in since the main pull request for rc1, primarily
        i915 and drm-misc and one amd fix. The drm core vblank regression fix
        is probably the most important thing.
      
        I've also added the mediatek feature pull, it wasn't that big and
        didn't look like it would have any impact outside of mediatek, in fact
        it looks to just be a single feature, and some cleanups"

      Documentation: ABI: mtd: describe "offset" more precisely · 7d84120b
      Rafał Miłecki authored
      So far Linux supported only two levels of MTD devices so we didn't need
      a very precise description for this sysfs file. With commit
      97519dc5
      
       ("mtd: partitions: add support for subpartitions") there
      is support for a tree structure so we should have more precise
      description. Using "parent" and "flash device" makes it more accurate.

      disable new gcc-7.1.1 warnings for now · bd664f6b
      Linus Torvalds authored
      
      
      I made the mistake of upgrading my desktop to the new Fedora 26 that
      comes with gcc-7.1.1.
      
      There's nothing wrong per se that I've noticed, but I now have 1500
      lines of warnings, mostly from the new format-truncation warning
      triggering all over the tree.
      
      We use 'snprintf()' and friends in a lot of places, and often know that
      the numbers are fairly small (ie a controller index or similar), but gcc
      doesn't know that, and sees an 'int', and thinks that it could be some
      huge number.  And then complains when our buffers are not able to fit
      the name for the ten millionth controller.
      
      These warnings aren't necessarily bad per se, and we probably want to
      look through them subsystem by subsystem, but at least during the merge
      window they just mean that I can't even see if somebody is introducing
      any *real* problems when I pull.
      
      So warnings disabled for now.

      net: stmmac: revert "support future possible different internal phy mode" · d93b07f8
      LABBE Corentin authored
      Since internal phy-mode is reserved for non-xMII protocol we cannot use
      it with dwmac-sun8i.
      Furthermore, all DT patchs which comes with this patch were cleaned, so
      the current state is broken.
      This reverts commit 1c2fa5f8 ("net: stmmac: support future possible different internal phy mode")

      sfc: don't read beyond unicast address list · c70d6815
      Bert Kenward authored
      If we have more than 32 unicast MAC addresses assigned to an interface
      we will read beyond the end of the address table in the driver when
      adding filters. The next 256 entries store multicast addresses, so we
      will end up attempting to insert duplicate filters, which is mostly
      harmless. If we add more than 288 unicast addresses we will then read
      past the multicast address table, which is likely to be more exciting.

      mlxsw: spectrum_router: Fix use-after-free in route replace · 7387dbbc
      Ido Schimmel authored
      While working on IPv6 route replace I realized we can have a
      use-after-free in IPv4 in case the replaced route is offloaded and the
      only one using its FIB info.
      
      The problem is that fib_table_insert() drops the reference on the FIB
      info of the replaced routes which is eventually freed via call_rcu().
      Since the driver doesn't hold a reference on this FIB info it can cause
      a use-after-free when it tries to clear the RTNH_F_OFFLOAD flag stored
      in fi->fib_flags.
      
      After running the following commands in a loop for enough time with a
      KASAN enabled kernel I finally got the below trace.
      
      $ ip route add 192.168.50.0/24 via 192.168.200.1 dev enp3s0np3

      With this patch the error path of mlxsw_sp_nexthop_init() is symmetric
      with mlxsw_sp_nexthop_fini(). Noticed during code review.

      net has the same issue.
      
      Add support for ntohl and htonl in tools/testing/selftests/bpf/bpf_endian.h.
      Also move bpf_helpers.h from samples/bpf to selftests/bpf and change
      compiler include logic so that programs in samples/bpf can access the headers
      in selftests/bpf, but not the other way around.

         - A followup pull request from Sagi for NVMe. Outside of fixups for
           NVMe, it also includes a series for ensuring that we properly
           quiesce hardware queues when browsing live tags.
      
         - Set of integrity fixes from Dmitry (mostly), fixing various issues
           for folks using DIF/DIX.
      
         - Fix for a bug introduced in cciss, with the req init changes. From
           Christoph.
      
         - Fix for a bug in BFQ, from Paolo.
