This addresses two issues that cause problems with viewperf maya-03 in
situation with memory pressure.
The first issue causes attempts to unreserve buffers if batched
reservation fails due to, for example, a signal pending. While previously
the ttm_eu api was resistant against this type of error, it is no longer
and the lockdep code will complain about attempting to unreserve buffers
that are not reserved. The issue is resolved by avoid calling
ttm_eu_backoff_reservation in the buffer reserve error path.
The second issue is that the binding_mutex may be held when user-space
fence objects are created and hence during memory reclaims. This may cause
recursive attempts to grab the binding mutex. The issue is resolved by not
holding the binding mutex across fence creation and submission.

Commit 3f5159a922 ("x86/asm/entry/32: Update -ENOSYS handling to match
the 64-bit logic") broke the ENOSYS handling for the 32-bit compat case.
The proper error return value was never loaded into %rax, except if
things just happened to go through the audit paths, which ended up
reloading the return value.
This moves the loading or %rax into the normal system call path, just to
make sure the error case triggers it. It's kind of sad, since it adds a
useless instruction to reload the register to the fast path, but it's
not like that single load from the stack is going to be noticeable.

Current filer rule optimization is broken in several ways:
(1) Can perform reads/writes beyond end of allocated tables.
(gianfar_ethtool.c:1326).
(2) It breaks badly for rules with more than 2 specifiers
(e.g. matching ip, port, tos).
Example:
# ethtool -N eth2 flow-type udp4 dst-ip 10.0.0.1 dst-port 1 tos 1 action 1
Added rule with ID 254
# ethtool -N eth2 flow-type udp4 dst-ip 10.0.0.2 dst-port 2 tos 2 action 9
Added rule with ID 253
# ethtool -N eth2 flow-type udp4 dst-ip 10.0.0.3 dst-port 3 tos 3 action 17
Added rule with ID 252
# ./filer_decode /sys/kernel/debug/gfar1/filer_raw

05: DIA == 0a000003 AND Q:11 ctrl:0000448c prop:0a000003
06: DPT == 00000002 AND Q:00 ctrl:0000008e prop:00000002
07: TOS == 00000002 AND Q:00 ctrl:0000008a prop:00000002
08: DIA == 0a000002 AND Q:09 ctrl:0000248c prop:0a000002

ff: MASK >= 00000000 Q:00 ctrl:00000020 prop:00000000
(Entire cluster gets AND-ed together).
(3) We observed that the masking rules it generates do not
play well with clustering on P2020. Only first rule
of the cluster would ever fire. Given that optimizer
relies heavily on masking this is very hard to fix.
Example:
# ethtool -N eth2 flow-type udp4 dst-ip 10.0.0.1 dst-port 1 action 1
Added rule with ID 254
# ethtool -N eth2 flow-type udp4 dst-ip 10.0.0.2 dst-port 2 action 9
Added rule with ID 253
# ethtool -N eth2 flow-type udp4 dst-ip 10.0.0.3 dst-port 3 action 17
Added rule with ID 252
# ./filer_decode /sys/kernel/debug/gfar1/filer_raw
00: MASK == 00000210 AND Q:00 ctrl:00000080 prop:00000210
01: FPR == 00000210 AND CLE Q:00 ctrl:00000281 prop:00000210
02: MASK == ffffffff AND Q:00 ctrl:00000080 prop:ffffffff
03: DPT == 00000003 AND Q:00 ctrl:0000008e prop:00000003
04: DIA == 0a000003 Q:11 ctrl:0000440c prop:0a000003
05: DPT == 00000002 AND Q:00 ctrl:0000008e prop:00000002
06: DIA == 0a000002 Q:09 ctrl:0000240c prop:0a000002
07: DIA == 0a000001 AND Q:00 ctrl:0000008c prop:0a000001
08: DPT == 00000001 CLE Q:01 ctrl:0000060e prop:00000001
ff: MASK >= 00000000 Q:00 ctrl:00000020 prop:00000000
Which looks correct according to the spec but only the first
(eth id 252)/last added rule for 10.0.0.3 will ever trigger.
As if filer did not treat the AND CLE as cluster start but
also kept AND-ing the rules. We found no errata covering this.
The fact that nobody noticed (2) or (3) makes me think
that this feature is not very widely used and we should just
remove it.

The packet gets dropped in qdisc (noop_enqueue).
The fix is to delay the sending of gratuitous ARPs till the bond dev's

It can also be worked around by setting num_grat_arp to more than 1.

In case we need to divert reads/writes using the slave MII bus, we may have
already fetched a valid PHY interface property from Device Tree, and that
mode is used by the PHY driver to make configuration decisions.
If we could not fetch the "phy-mode" property, we will assign p->phy_interface
to PHY_INTERFACE_MODE_NA, such that we can actually check for that condition as

When using nested btrees, the top leaves of the top levels contain
block addresses for the root of the next tree down. If we shadow a
shared leaf node the leaf values (sub tree roots) should be incremented
accordingly.
This is only an issue if there is metadata sharing in the top levels.
Which only occurs if metadata snapshots are being used (as is possible
with dm-thinp). And could result in a block from the thinp metadata
snap being reused early, thus corrupting the thinp metadata snap.

__rb_free_aux() may be called twice resulting in a double free of

these modules use Kbuild for their names, they too need to be checked
by localmodconfig. This was fixed by Richard Weinberger.

Here's an important regression fix for the 4.2-rc series that ensures
user space isn't given invalid LTK values. The bug essentially prevents
the encryption of subsequent LE connections, i.e. makes it impossible to
pair devices over LE.
Let me know if there are any issues pulling. Thanks.

We are not interested in interrupts for partially transmitted frames.
Unlike SCC and FCC, the FEC doesn't handle the I bit in buffer
descriptors, instead it defines two interrupt bits, TXB and TXF.
We have to mask TXB in order to only get interrupts once the
frame is fully transmitted.

Since 906c55579a ("timekeeping: Copy the shadow-timekeeper over the
real timekeeper last") it has become possible on ARM to:
- Obtain a CLOCK_MONOTONIC_COARSE or CLOCK_REALTIME_COARSE timestamp
via syscall.
- Subsequently obtain a timestamp for the same clock ID via VDSO which
predates the first timestamp (by one jiffy).
This is because ARM's update_vsyscall is deriving the coarse time
using the __current_kernel_time interface, when it should really be
using the timekeeper object provided to it by the timekeeping core.
It happened to work before only because __current_kernel_time would
access the same timekeeper object which had been passed to
update_vsyscall. This is no longer the case.

Once pm_runtime_set_active() gets called, the kernel assumes that given
device has already enabled runtime pm and will call pm_runtime_suspend()
without matching pm_runtime_resume(). In case of DRM FIMC IPP driver,
this will result in calling clk_disable() without respective call to
clk_enable(). This patch removes call to pm_runtime_set_active() to
ensure that pm_runtime_suspend/resume calls will match.
