Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net

There were quite a few overlapping sets of changes here.

Daniel's bug fix for off-by-ones in the new BPF branch instructions,
along with the added allowances for "data_end > ptr + x" forms
collided with the metadata additions.

Along with those three changes came veritifer test cases, which in
their final form I tried to group together properly.  If I had just
trimmed GIT's conflict tags as-is, this would have split up the
meta tests unnecessarily.

In the socketmap code, a set of preemption disabling changes
overlapped with the rename of bpf_compute_data_end() to
bpf_compute_data_pointers().

Changes were made to the mv88e6060.c driver set addr method
which got removed in net-next.

The hyperv transport socket layer had a locking change in 'net'
which overlapped with a change of socket state macro usage
in 'net-next'.

+Linux Kernel Enforcement Statement
+----------------------------------
+
+As developers of the Linux kernel, we have a keen interest in how our software
+is used and how the license for our software is enforced.  Compliance with the
+reciprocal sharing obligations of GPL-2.0 is critical to the long-term
+sustainability of our software and community.
+
+Although there is a right to enforce the separate copyright interests in the
+contributions made to our community, we share an interest in ensuring that
+individual enforcement actions are conducted in a manner that benefits our
+community and do not have an unintended negative impact on the health and
+growth of our software ecosystem.  In order to deter unhelpful enforcement
+actions, we agree that it is in the best interests of our development
+community to undertake the following commitment to users of the Linux kernel
+on behalf of ourselves and any successors to our copyright interests:
+
+    Notwithstanding the termination provisions of the GPL-2.0, we agree that
+    it is in the best interests of our development community to adopt the
+    following provisions of GPL-3.0 as additional permissions under our
+    license with respect to any non-defensive assertion of rights under the
+    license.
+
+        However, if you cease all violation of this License, then your license
+        from a particular copyright holder is reinstated (a) provisionally,
+        unless and until the copyright holder explicitly and finally
+        terminates your license, and (b) permanently, if the copyright holder
+        fails to notify you of the violation by some reasonable means prior to
+        60 days after the cessation.
+
+        Moreover, your license from a particular copyright holder is
+        reinstated permanently if the copyright holder notifies you of the
+        violation by some reasonable means, this is the first time you have
+        received notice of violation of this License (for any work) from that
+        copyright holder, and you cure the violation prior to 30 days after
+        your receipt of the notice.
+
+Our intent in providing these assurances is to encourage more use of the
+software.  We want companies and individuals to use, modify and distribute
+this software.  We want to work with users in an open and transparent way to
+eliminate any uncertainty about our expectations regarding compliance or
+enforcement that might limit adoption of our software.  We view legal action
+as a last resort, to be initiated only when other community efforts have
+failed to resolve the problem.
+
+Finally, once a non-compliance issue is resolved, we hope the user will feel
+welcome to join us in our efforts on this project.  Working together, we will
+be stronger.
+
+Except where noted below, we speak only for ourselves, and not for any company
+we might work for today, have in the past, or will in the future.

+        help
+          If you want to debug problems which hang or crash the kernel early
+          on boot and the crashing machine has a FireWire port, you can use
+          this feature to remotely access the memory of the crashed machine
+          over FireWire. This employs remote DMA as part of the OHCI1394
+          specification which is now the standard for FireWire controllers.
+
+          With remote DMA, you can monitor the printk buffer remotely using
+          firescope and access all memory below 4GB using fireproxy from gdb.
+          Even controlling a kernel debugger is possible using remote DMA.
+
+          Usage:
+
+          If ohci1394_dma=early is used as boot parameter, it will initialize
+          all OHCI1394 controllers which are found in the PCI config space.
+
+          As all changes to the FireWire bus such as enabling and disabling
+          devices cause a bus reset and thereby disable remote DMA for all
+          devices, be sure to have the cable plugged and FireWire enabled on
+          the debugging host before booting the debug target for debugging.
+
+          This code (~1k) is freed after boot. By then, the firewire stack
+          in charge of the OHCI-1394 controllers should be used instead.
