Allocate VF interrupts using VPINT_ALLOC_PCI. Multiple interrupts are
specified as a range from "first" to "last".

Also, according to the spec, the queue mapping for a VF needs to be set
in both contig and scatter queue modes. So make this change as well.

these limitations are fixed in the firmware.

Merge branch 'siginfo-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace

Pull siginfo updates from Eric Biederman:
 "I have been slowly sorting out siginfo and this is the culmination of
  that work.

  The primary result is in several ways the signal infrastructure has
  been made less error prone. The code has been updated so that manually
  specifying SEND_SIG_FORCED is never necessary. The conversion to the
  new siginfo sending functions is now complete, which makes it
  difficult to send a signal without filling in the proper siginfo
  fields.

  At the tail end of the patchset comes the optimization of decreasing
  the size of struct siginfo in the kernel from 128 bytes to about 48
  bytes on 64bit. The fundamental observation that enables this is by
  definition none of the known ways to use struct siginfo uses the extra
  bytes.

  This comes at the cost of a small user space observable difference.
  For the rare case of siginfo being injected into the kernel only what
  can be copied into kernel_siginfo is delivered to the destination, the
  rest of the bytes are set to 0. For cases where the signal and the
  si_code are known this is safe, because we know those bytes are not
  used. For cases where the signal and si_code combination is unknown
  the bits that won't fit into struct kernel_siginfo are tested to
  verify they are zero, and the send fails if they are not.

  I made an extensive search through userspace code and I could not find
  anything that would break because of the above change. If it turns out
  I did break something it will take just the revert of a single change
  to restore kernel_siginfo to the same size as userspace siginfo.

  Testing did reveal dependencies on preferring the signo passed to
  sigqueueinfo over si->signo, so bit the bullet and added the
  complexity necessary to handle that case.

  Testing also revealed bad things can happen if a negative signal
  number is passed into the system calls. Something no sane application
  will do but something a malicious program or a fuzzer might do. So I
  have fixed the code that performs the bounds checks to ensure negative
  signal numbers are handled"

The networking merge brought in the experimental support for the
Qualcomm ath10k system NOC, which selects QCOM_QMI_HELPERS as a
dependency.

But the ATH10K_SNOC option (which selects QCOM_QMI_HELPERS) depends on
ARCH_QCOM || COMPILE_TEST in order to get wider build testing than just
the unusual QCOM architecture build, while the QCOM_QMI_HELPERS option
doesn't have that COMPILE_TEST option and is limited to only ARCH_QCOM.

As a result, a "make allmodconfig" complains

With EDT model, SRTT no longer is inflated by pacing delays.

This means that RTO and some other xmit timers might be setup
incorrectly. This is particularly visible with either :

- Very small enforced pacing rates (SO_MAX_PACING_RATE)
- Reduced rto (from the default 200 ms)

This can lead to TCP flows aborts in the worst case,
or spurious retransmits in other cases.

For example, this session gets far more throughput
than the requested 80kbit :

$ netperf -H 127.0.0.2 -l 100 -- -q 10000
MIGRATED TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 127.0.0.2 () port 0 AF_INET

With the fix :

$ netperf -H 127.0.0.2 -l 100 -- -q 10000
MIGRATED TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 127.0.0.2 () port 0 AF_INET

EDT allows for better control of rtx timers, since TCP has
a better idea of the earliest departure time of each skb
in the rtx queue. We only have to eventually add to the
timer the difference of the EDT time with current time.

This broke tcp_poll for SMC fallback: An AF_SMC socket establishes an
internal TCP socket for the initial handshake with the remote peer.
Whenever the SMC connection can not be established this TCP socket is
used as a fallback. All socket operations on the SMC socket are then
forwarded to the TCP socket. In case of poll, the file->private_data
pointer references the SMC socket because the TCP socket has no file
assigned. This causes tcp_poll to wait on the wrong socket.

There is a compatibility issue between RTL8211E implemented
in Developerbox and netsec ethernet controller IP.

Our MDIO controller stops MDC clock right after the write
access, but RTL8211E expects MDC clock must be kept toggling
for several clock cycle with MDIO high before entering
the IDLE state. Without keeping clock after write access,
write access is not correctly handled and register is not
updated.

To meet this requirement, netsec driver needs to issue dummy
read(e.g. read PHYID1(offset 0x2) register) right after write
access, to keep MDC clock.

We think this compatibility issue is a problem specific to
our MDIO controller and RTL8211E.

In ndo_stop, driver resets the netsec ethernet controller IP.
When the netsec IP is reset, HW running mode turns to NRM mode
and driver has to wait until this mode transition completes.

But mode transition to NRM will not complete if the PHY is
in normal operation state. Netsec IP requires PHY is in
power down state when it is reset.

This modification stops the PHY before resetting netsec.

Together with this modification, phy_addr is stored in netsec_priv
structure because ndev->phydev is not yet ready in ndo_init.

     This allows to speed up the PMI handler by avoiding unnecessary MSR
     writes and make it more accurate. (Andi Kleen)
