====================
mlx4 bug fixes for 4.9
This patchset includes 2 bug fixes:
* In patch 1 we revert the commit that avoids invoking unregister_netdev
in shutdown flow, as it introduces netdev presence issues where
it can be accessed unsafely by ndo operations during the flow.
* Patch 2 is a simple fix for a variable uninitialization issue.

This reverts commit 9d76931180557270796f9631e2c79b9c7bb3c9fb.
Using unregister_netdev at shutdown flow prevents calling
the netdev's ndos or trying to access its freed resources.
This fixes crashes like the following:

Most 5XX targets have GPMU (Graphics Power Management Unit) that
handles a lot of the heavy lifting for power management including
thermal and limits management and dynamic power collapse. While
the GPMU itself is optional, it is usually nessesary to hit
aggressive power targets.
The GPMU firmware needs to be loaded into the GPMU at init time via a
shared hardware block of registers. Using the GPU to write the microcode
is more efficient than using the CPU so at first load create an indirect
buffer that can be executed during subsequent initalization sequences.
After loading the GPMU gets initalized through a shared register
interface and then we mostly get out of its way and let it do
its thing.

The adreno code inherited a silly workaround from downstream
from the bad old days before decent clock control. grp_clk[0]
(named 'src_clk') doesn't actually exist - it was used as a proxy
for whatever the core clock actually was (usually 'core_clk').
All targets should be able to correctly request 'core_clk' and
get the right thing back so zap the anachronism and directly
use grp_clk[0] to control the clock rate.

Add a new generic function to write a "64" bit value. This isn't
actually a 64 bit operation, it just writes the upper and lower
32 bit of a 64 bit value to a specified LO and HI register. If
a particular target doesn't support one of the registers it can
mark that register as SKIP and writes/reads from that register
will be quietly dropped.
This can be immediately put in place for the ringbuffer base and
the RPTR address. Both writes are converted to use
adreno_gpu_write64() with their respective high and low registers
and the high register appropriately marked as SKIP for both 32 bit
targets (a3xx and a4xx). When a5xx comes it will define valid target
registers for the 'hi' option and everything else will just work.

Add some new functions to manipulate GPU registers. gpu_read64 and
gpu_write64 can read/write a 64 bit value to two 32 bit registers.
For 4XX and older these are normally perfcounter registers, but
future targets will use 64 bit addressing so there will be many
more spots where a 64 bit read and write are needed.
gpu_rmw() does a read/modify/write on a 32 bit register given a mask
and bits to OR in.

net: phy: realtek: fix RTL8211F TX-delay handling
The RTL8211F PHY driver currently enables the TX-delay only when the
phy-mode is PHY_INTERFACE_MODE_RGMII. This is incorrect, because there
are three RGMII variations of the phy-mode which explicitly request the
PHY to enable the RX and/or TX delay, while PHY_INTERFACE_MODE_RGMII
specifies that the PHY should disable the RX and/or TX delays.
Additionally to the RTL8211F PHY driver change this contains a small
update to the phy-mode documentation to clarify the purpose of the
RGMII phy-modes.
While this may not be perfect yet it's at least a start. Please feel
free to drop this patch from this series and send an improved version
yourself.
These patches are the results of recent discussions, see [0]

The old logic always enabled the TX-delay when the phy-mode was set to
PHY_INTERFACE_MODE_RGMII. There are dedicated phy-modes which tell the
PHY driver to enable the RX and/or TX delays:
- PHY_INTERFACE_MODE_RGMII should disable the RX and TX delay in the
PHY (if required, the MAC should add the delays in this case)
- PHY_INTERFACE_MODE_RGMII_ID should enable RX and TX delay in the PHY
- PHY_INTERFACE_MODE_RGMII_TXID should enable the TX delay in the PHY
- PHY_INTERFACE_MODE_RGMII_RXID should enable the RX delay in the PHY
(currently not supported by RTL8211F)
With this patch we enable the TX delay for PHY_INTERFACE_MODE_RGMII_ID
and PHY_INTERFACE_MODE_RGMII_TXID.
Additionally we now explicity disable the TX-delay, which seems to be
enabled automatically after a hard-reset of the PHY (by triggering it's
reset pin) to get a consistent state (as defined by the phy-mode).
This fixes a compatibility problem with some SoCs where the TX-delay was
also added by the MAC. With the TX-delay being applied twice the TX
clock was off and TX traffic was broken or very slow (<10Mbit/s) on
1000Mbit/s links.

RGMII requires special RX and/or TX delays depending on the actual
hardware circuit/wiring. These delays can be added by the MAC, the PHY
or the designer of the circuit (the latter means that no delay has to
be added by PHY or MAC).
There are 4 RGMII phy-modes used describe where a delay should be
applied:
- rgmii: the RX and TX delays are either added by the MAC (where the
exact delay is typically configurable, and can be turned off when no
extra delay is needed) or not needed at all (because the hardware
wiring adds the delay already). The PHY should neither add the RX nor
TX delay in this case.
- rgmii-rxid: configures the PHY to enable the RX delay. The MAC should
not add the RX delay in this case.
- rgmii-txid: configures the PHY to enable the TX delay. The MAC should
not add the TX delay in this case.
- rgmii-id: combines rgmii-rxid and rgmii-txid and thus configures the
PHY to enable the RX and TX delays. The MAC should neither add the RX
nor TX delay in this case.
Document these cases in the ethernet.txt documentation to make it clear
when to use each mode.
If applied incorrectly one might end up with MAC and PHY both enabling
for example the TX delay, which breaks ethernet TX traffic on 1000Mbit/s
links.

CEA-861 specifies that the vertical front porch may vary by one or two
lines for specific VICs. Up to now we've only considered a mode to match
the VIC if it matched the shortest possible vertical front porch length
(as that is the variant we store in cea_modes[]). Let's allow our VIC
matching to work with the other timings variants as well so that that
we'll send out the correct VIC if the variant actually used isn't the
one with the shortest vertical front porch.

Roi reported a crash in flower where tp->root was NULL in ->classify()
callbacks. Reason is that in ->destroy() tp->root is set to NULL via
RCU_INIT_POINTER(). It's problematic for some of the classifiers, because
this doesn't respect RCU grace period for them, and as a result, still
outstanding readers from tc_classify() will try to blindly dereference
a NULL tp->root.
The tp->root object is strictly private to the classifier implementation
and holds internal data the core such as tc_ctl_tfilter() doesn't know
about. Within some classifiers, such as cls_bpf, cls_basic, etc, tp->root
is only checked for NULL in ->get() callback, but nowhere else. This is
misleading and seemed to be copied from old classifier code that was not
cleaned up properly. For example, d3fa76ee6b4a ("[NET_SCHED]: cls_basic:
fix NULL pointer dereference") moved tp->root initialization into ->init()
routine, where before it was part of ->change(), so ->get() had to deal
with tp->root being NULL back then, so that was indeed a valid case, after
d3fa76ee6b4a, not really anymore. We used to set tp->root to NULL long
ago in ->destroy(), see 47a1a1d4be29 ("pkt_sched: remove unnecessary xchg()
in packet classifiers"); but the NULLifying was reintroduced with the
RCUification, but it's not correct for every classifier implementation.
In the cases that are fixed here with one exception of cls_cgroup, tp->root
object is allocated and initialized inside ->init() callback, which is always
performed at a point in time after we allocate a new tp, which means tp and
thus tp->root was not globally visible in the tp chain yet (see tc_ctl_tfilter()).
Also, on destruction tp->root is strictly kfree_rcu()'ed in ->destroy()
handler, same for the tp which is kfree_rcu()'ed right when we return
from ->destroy() in tcf_destroy(). This means, the head object's lifetime
for such classifiers is always tied to the tp lifetime. The RCU callback
invocation for the two kfree_rcu() could be out of order, but that's fine
since both are independent.
Dropping the RCU_INIT_POINTER(tp->root, NULL) for these classifiers here
means that 1) we don't need a useless NULL check in fast-path and, 2) that
outstanding readers of that tp in tc_classify() can still execute under
respect with RCU grace period as it is actually expected.
Things that haven't been touched here: cls_fw and cls_route. They each
handle tp->root being NULL in ->classify() path for historic reasons, so
their ->destroy() implementation can stay as is. If someone actually
cares, they could get cleaned up at some point to avoid the test in fast
path. cls_u32 doesn't set tp->root to NULL. For cls_rsvp, I just added a
!head should anyone actually be using/testing it, so it at least aligns with
cls_fw and cls_route. For cls_flower we additionally need to defer rhashtable
destruction (to a sleepable context) after RCU grace period as concurrent
readers might still access it. (Note that in this case we need to hold module
reference to keep work callback address intact, since we only wait on module
unload for all call_rcu()s to finish.)
This fixes one race to bring RCU grace period guarantees back. Next step
as worked on by Cong however is to fix 1e052be69d04 ("net_sched: destroy
proto tp when all filters are gone") to get the order of unlinking the tp
in tc_ctl_tfilter() for the RTM_DELTFILTER case right by moving
RCU_INIT_POINTER() before tcf_destroy() and let the notification for
removal be done through the prior ->delete() callback. Both are independant
issues. Once we have that right, we can then clean tp->root up for a number
of classifiers by not making them RCU pointers, which requires a new callback
(->uninit) that is triggered from tp's RCU callback, where we just kfree()
tp->root from there.

The new atomic modesetting/pageflip code for nv50+ for
Linux 4.10+ no longer uses pageflip irq's to signal
flip completion. Instead it polls for flip completion
from within a kthread/work queue.
This creates a race between the vblank irq handler
updating the vblank count and timestamp for the
vblank of flip completion, and the kthread's
polling code detecting flip completion and sending
out the flip completion event.
Depending on who executes a few microseconds earlier,
the flip completion event will either contain correct
count/timestamp or a stale count/timestamp from the
previous vblank. This error was observed for about
50% of all executed flips, e.g., observable under DRI2
by the Xorg.log filling with flip handler warning
messages.
Call drm_accurate_vblank_count() before sending
out flip completion events to enforce a vblank
count/ts update for the vblank of flip completion
and avoid stale counts/timestamps.
This fix leads to one redundant call to drm_update_vblank_count
for each completed flip, but no other side effects. On
a ~6 year old Core i7 M620@ 2.67GHz the redundant call
costs about 10 usecs per flip

In commit e4bf4f76962b ("tipc: simplify packet sequence number
handling") we changed the internal representation of the packet
sequence number counters from u32 to u16, reflecting what is really
sent over the wire.
Since then some link statistics counters have been displaying incorrect
values, partially because the counters meant to be used as sequence
number snapshots are now used as direct counters, stored as u32, and
partially because some counter updates are just missing in the code.
In this commit we correct this in two ways. First, we base the
displayed packet sent/received values on direct counters instead
of as previously a calculated difference between current sequence
number and a snapshot. Second, we add the missing updates of the
counters.
This change is compatible with the current netlink API, and requires
no changes to the user space tools.

net: fix phydev reference leaks
This series fixes a number of phydev reference leaks (and one of_node
leak) due to failure to put the reference taken by of_phy_find_device().
Note that I did not try to fix drivers/net/phy/xilinx_gmii2rgmii.c which
still leaks a reference.
Against net but should apply just as fine to net-next.
v2:
- use put_device() instead of phy_dev_free() to put the references
taken in net/dsa (patch 1/4).
- add four new patches fixing similar leaks

Make sure to drop the reference taken by of_phy_find_device() during
probe on probe errors and on driver unbind.
Also drop the of_node reference taken by of_parse_phandle() in the same
path.
