Pull RISC-V fixes from Palmer Dabbelt:
 "This week is a bit bigger than I expected. That's my fault, as I
  missed a few patches while I was at Plumbers last week. We have:

   - A fix to a quite embarassing issue where raw_copy_to_user() was
     implemented with asm_copy_from_user() (and vice versa).

   - Improvements to our makefile to allow flat binaries to be
     generated.

   - A build fix that predeclares "struct module" at the top of
     <asm/module.h>, which triggers warnings later in that header.

   - The addition of our own <uapi/asm/unistd> header, which is
     necessary to align our stat ABI on 32-bit systems.

   - A fix to avoid printing a warning when the S or U bits are set in
     print_isa().

  I already have one patch in the queue for next week"

      Pull MIPS fixes from Paul Burton:
 "A few MIPS fixes for 4.20:

   - Re-enable the Cavium Octeon USB driver in its defconfig after it
     was accidentally removed back in 4.14.

   - Have early memblock allocations be performed bottom-up to more
     closely match the behaviour we used to have with bootmem, which
     seems a safer choice since we've seen fallout from the change made
     in the 4.20 merge window.

   - Simplify max_low_pfn calculation in the NUMA code for the Loongson3
     and SGI IP27 platforms to both clean up the code & ensure
     max_low_pfn has been set appropriately before it is used"

      Removes the warning about an unsupported ISA when reading /proc/cpuinfo
on QEMU. The "S" extension is not being returned as it is not accessible

      riscv: add asm/unistd.h UAPI header · 27f8899d
      David Abdurachmanov authored 
      Marcin Juszkiewicz reported issues while generating syscall table for riscv
using 4.20-rc1. The patch refactors our unistd.h files to match some other
architectures.

- Add asm/unistd.h UAPI header, which has __ARCH_WANT_NEW_STAT only for 64-bit
- Remove asm/syscalls.h UAPI header and merge to asm/unistd.h
- Adjust kernel asm/unistd.h

So now asm/unistd.h UAPI header should show all syscalls for riscv.

Before this, Makefile simply put `#include <asm-generic/unistd.h>` into
generated asm/unistd.h UAPI header thus user didn't see:

- __NR_riscv_flush_icache
- __NR_newfstatat
- __NR_fstat

which are supported by riscv kernel.

      RISC-V: Build flat and compressed kernel images · c0fbcd99
      Anup Patel authored 
      This patch extends Linux RISC-V build system to build and install:
Image - Flat uncompressed kernel image
Image.gz - Flat and GZip compressed kernel image

Quiet a few bootloaders (such as Uboot, UEFI, etc) are capable of
booting flat and compressed kernel images. In case of Uboot, booting
Image or Image.gz is achieved using bootm command.

The flat and uncompressed kernel image (i.e. Image) is very useful
in pre-silicon developent and testing because we can create back-door
HEX files for RAM on FPGAs from Image.

      tuntap: fix multiqueue rx · 8ebebcba
      Matthew Cover authored 
      When writing packets to a descriptor associated with a combined queue, the
packets should end up on that queue.

Before this change all packets written to any descriptor associated with a
tap interface end up on rx-0, even when the descriptor is associated with a
different queue.

The rx traffic can be generated by either of the following.
  1. a simple tap program which spins up multiple queues and writes packets
     to each of the file descriptors
  2. tx from a qemu vm with a tap multiqueue netdev

The queue for rx traffic can be observed by either of the following (done
on the hypervisor in the qemu case).
  1. a simple netmap program which opens and reads from per-queue
     descriptors
  2. configuring RPS and doing per-cpu captures with rxtxcpu

Alternatively, if you printk() the return value of skb_get_rx_queue() just
before each instance of netif_receive_skb() in tun.c, you will get 65535
for every skb.

Calling skb_record_rx_queue() to set the rx queue to the queue_index fixes
the association between descriptor and rx queue.

      ipv6: Fix PMTU updates for UDP/raw sockets in presence of VRF · 7ddacfa5
      David Ahern authored 
      Preethi reported that PMTU discovery for UDP/raw applications is not
working in the presence of VRF when the socket is not bound to a device.
The problem is that ip6_sk_update_pmtu does not consider the L3 domain
of the skb device if the socket is not bound. Update the function to
set oif to the L3 master device if relevant.

Fixes: ca254490 ("net: Add VRF support to IPv6 stack")
