For ease of use (i.e. avoiding a few checks and function calls), store
the object's cache coherency next to the cache is dirty bit.
Specifically this patch aims to reduce the frequency of no-op calls to
i915_gem_object_clflush() to counter-act the increase of such calls for
GPU only objects in the previous patch.

Currently, we only mark the CPU cache as dirty if we skip a clflush.
This leads to some confusion where we have to ask if the object is in
the write domain or missed a clflush. If we always mark the cache as
dirty, this becomes a much simply question to answer.
The goal remains to do as few clflushes as required and to do them as
late as possible, in the hope of deferring the work to a kthread and not
block the caller (e.g. execbuf, flips).
v2: Always call clflush before GPU execution when the cache_dirty flag
is set. This may cause some extra work on llc systems that migrate dirty
buffers back and forth - but we do try to limit that by only setting
cache_dirty at the end of the gpu sequence.
v3: Always mark the cache as dirty upon a level change, as we need to
invalidate any stale cachelines due to external writes.

ftrace_caller() depends on a modified regs->nip to detect if a certain
function has been livepatched. However, with KPROBES_ON_FTRACE, it is
possible for regs->nip to have been modified by the kprobes pre_handler
(jprobes, for instance). In this case, we do not want to invoke the
livepatch_handler so as not to consume the livepatch stack.
To distinguish between the two (kprobes and livepatch), we check if
there is an active kprobe on the current function. If there is, then we
know for sure that it must have modified the NIP as we don't support
livepatching a kprobe'd function. In this case, we simply skip the
livepatch_handler and branch to the new NIP. Otherwise, the
livepatch_handler is invoked.

This is essentially commit 237d28db03 ("ftrace/jprobes/x86: Fix
conflict between jprobes and function graph tracing"), but for powerpc.
Jprobes breaks function_graph tracing since the jprobe hook needs to use
jprobe_return(), which never returns back to the hook, but instead to
the original jprobe'd function. The solution is to momentarily pause
function_graph tracing before invoking the jprobe hook and re-enable it
when returning back to the original jprobe'd function.

The Armada 7K and 8K SoCs use the same gpio controller as most of the
other mvebu SoCs. However, the main difference is that the GPIO
controller is part of a bigger system controller, and a syscon is used to
control the overall system controller. Therefore, the driver needs to be
adjusted to retrieve the regmap of the syscon to access registers, and
account for the fact that registers are located at a certain offset
within the regmap.
This commit add the support of the syscon and introduce a new variant for
this case.
It was based on the preliminary work of Thomas Petazzoni.

Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma
Pull rdma fixes from Doug Ledford:
"I had thought at the time of the last pull request that there wouldn't
be much more to go, but several things just kept trickling in over the
last week.
Instead of just the six patches to bnxt_re that I had anticipated,
there are another five IPoIB patches, two qedr patches, and a few
other miscellaneous patches.
The bnxt_re patches are more lines of diff than I like to submit this
late in the game. That's mostly because of the first two patches in
the series of six. I almost dropped them just because of the lines of
churn, but on a close review, a lot of the churn came from removing
duplicated code sections and consolidating them into callable
routines. I felt like this made the number of lines of change more
acceptable, and they address problems, so I left them. The remainder
of the patches are all small, well contained, and well understood.
These have passed 0day testing, but have not been submitted to
linux-next (but a local merge test with your current master was
without any conflicts).
Summary:
- A fix for fix eea40b8f62 ("infiniband: call ipv6 route lookup via
the stub interface")
- Six patches against bnxt_re...the first two are considerably larger

As USB 3.0 PHY is attached to the MDIO bus this module should provide a
MDIO driver and use a proper bus layer. This is a proper (cleaner)
solution which doesn't require code to know this specific MDIO bus
details. It also allows reusing the driver with other MDIO buses.
For now keep platform device support in place. We may consider dropping
it once MDIO bindings gets used "everywhere".

Thanks to work done by Broadcom explaining their USB 3.0 PHY details we
know it's attached to the MDIO bus. Use this knowledge to update the
binding: make it a subnode to the MDIO bus and rework way of specifying
required registers. This will describe hardware more precisely and will
allow to support (describe) more devices attached to the MDIO.
While compatibility strings remain the same there isn't a direct
conflict (compatibility breakage) for the binding. Originally it wasn't
supposed to be used for MDIO subnode so this change should be safe
unless some operating system was probing MDIO subnodes as standalone
devices.

When we finally start using MDIO layer then bus initialization will be
handled in a separated driver. It means our code handling this has to be
used for the platform driver only.

Our current writing function accesses PHY directly bypassing MDIO layer.
The aim is to extend this module to also behave as MDIO driver. This
will require using different writing function which can be handled
cleanly by having an extra pointer like this.

Move MDIO specific code to the writing helper function. This makes init
code a bit more generic and doesn't require it to track what happens
after every write.
