If the pending indexes are released /after/ pushing the Tx response
then a stale pending index may be used if a new Tx request is
immediately pushed by the frontend. The may cause various WARNINGs or
BUGs if the stale pending index is actually still in use.
Fix this by releasing the pending index before pushing the Tx
response.
The full barrier for the pending ring update is not required since the
the Tx response push already has a suitable write barrier.

Before da413eec729d ("packet: Fixed TPACKET V3 to signal poll when block is
closed rather than every packet") poll listening for an af_packet socket was
not signaled if there was no packets to process. After the patch poll is
signaled evety time when block retire timer expires. That happens because
af_packet closes the current block on timeout even if the block is empty.
Passing empty blocks to the user not only wastes CPU but also wastes ring
buffer space increasing probability of packets dropping on small timeouts.

Commit 06d961a8e210 ("mac80211/minstrel: use the new rate control API")
inverted the condition 'if (msr->sample_limit != 0)' to
'if (!msr->sample_limit != 0)'. But it is confusing both to people and
compilers (gcc5):
net/mac80211/rc80211_minstrel.c: In function 'minstrel_get_rate':
net/mac80211/rc80211_minstrel.c:376:26: warning: logical not is only applied to the left hand side of comparison
if (!msr->sample_limit != 0)
^
Let there be only 'if (!msr->sample_limit)'.

As soon as the interrupt has been enabled by devm_request_irq(), the
interrupt routine may be called, depending on the current status of the
hardware.
However, at that point rcar_thermal_common hasn't been initialized
complely yet. E.g. rcar_thermal_common.base is still NULL, causing a
NULL pointer dereference:

When CONFIG_THERMAL is not enabled, it is better to introduce
equivalent dummy functions in the exported header than to
introduce #ifdeffery in drivers using the function.
This will prevent issues such as that reported in:
http://www.spinics.net/lists/linux-next/msg31573.html
While at it switch over to IS_ENABLED for thermal macros
to allow for thermal framework to be built as framework
and relevant APIs be usable by relevant drivers as a result.

In commit 87517d26d888 ("ARM: dts: dra7-evm: Add extcon nodes for USB")
we enabled Extcon USB gpio to tackle the USB ID pin and get
peripheral mode to work.
But the extcon-gpio-usb driver [1] didn't make it into v4.0
and this makes the USB driver defer probe indefinitely breaking
USB Host functionality.
As a temporary fix we remove the extcon handle from the
USB controller and add it back when the extcon driver
merges in v4.1.

Offset for smc91x must be zero otherwise smc91x linux kernel driver does not
detect smc91x ethernet hardware in qemu N900 machine.
The 0x300 offset was used to supress a warning the smsc911x
driver produces about non-standard offset as 0x300 seems to
be the EEPROM default. As only three address lines are
connected both 0 and 0x300 will work just fine with 0 being
correct. The warning about the non-standard offset can be
fixed by writing to EEPROM as that's needed in any case to
set the MAC address.

Commit 7800064ba507 ("ARM: dts: Add basic dm816x device tree
configuration") added basic devices for dm816x, but I was not able
to test the USB completely because of an unconfigured USB phy, and
I only tested it to make sure the Mentor chips are detected and
clocked without a phy.
After testing the USB with actual devices I noticed a few issues
that should be fixed to avoid confusion:
- The USB id pin on dm8168-evm is hardwired and can be changed
only by software. As there are two USB-A type connectors, let's
start both in host mode instead of otg.
- The Mentor core is configured in such a way on dm8168-evm that
it's not capable of multipoint at least on revision c board
that I have.
- We need ranges for the syscon to properly set up the phy as
children of the SCM syscon area.
- Let's not disable the second interface, the board specific
dts files can do that if really needed. Most boards should
just keep it enabled to ensure the device is idled properly.
Note that also a phy and several musb fixes are still needed to
make the USB to work properly in addition to this fix.

Atm, it's possible that the interrupt handler is called when the device
is in D3 or some other low-power state. It can be due to another device
that is still in D0 state and shares the interrupt line with i915, or on
some platforms there could be spurious interrupts even without sharing
the interrupt line. The latter case was reported by Klaus Ethgen using a
Lenovo x61p machine (gen 4). He noticed this issue via a system
suspend/resume hang and bisected it to the following commit:
commit e11aa362308f5de467ce355a2a2471321b15a35c
Author: Jesse Barnes <jbarnes@virtuousgeek.org>
Date: Wed Jun 18 09:52:55 2014 -0700
drm/i915: use runtime irq suspend/resume in freeze/thaw
This is a problem, since in low-power states IIR will always read
0xffffffff resulting in an endless IRQ servicing loop.
Fix this by handling interrupts only when the driver explicitly enables
them and so it's guaranteed that the interrupt registers return a valid
value.
Note that this issue existed even before the above commit, since during
runtime suspend/resume we never unregistered the handler.
v2:
- clarify the purpose of smp_mb() vs. synchronize_irq() in the
code comment (Chris)
v3:
- no need for an explicit smp_mb(), we can assume that synchronize_irq()
and the mmio read/writes in the install hooks provide for this (Daniel)
- remove code comment as the remaining synchronize_irq() is self
explanatory (Daniel)
v4:
- drm_irq_uninstall() implies synchronize_irq(), so no need to call it
explicitly (Daniel)

When converting from implicitly tracked execlist queue items to ref counted
requests, not all frees of requests were replaced with unrefs, and extraneous
refs/unrefs of contexts were added.
Correct the unbalanced refcount & replace the frees.
Remove a noisy warning when hitting the request creation path.
drm_i915_gem_request and intel_context are both kref reference counted
structures. Upon allocation, drm_i915_gem_request's ref count should be
bumped using kref_init. When a context is assigned to the request,
the context's reference count should be bumped using i915_gem_context_reference.
i915_gem_request_reference will reduce the context reference count when
the request is freed.

The KSTK_EIP() and KSTK_ESP() macros should return the user program
counter (PC) and stack pointer (A0StP) of the given task. These are used
to determine which VMA corresponds to the user stack in
/proc/<pid>/maps, and for the user PC & A0StP in /proc/<pid>/stat.
However for Meta the PC & A0StP from the task's kernel context are used,
resulting in broken output. For example in following /proc/<pid>/maps
output, the 3afff000-3b021000 VMA should be described as the stack:
# cat /proc/self/maps
...
100b0000-100b1000 rwxp 00000000 00:00 0 [heap]
3afff000-3b021000 rwxp 00000000 00:00 0
And in the following /proc/<pid>/stat output, the PC is in kernel code
(1074234964 = 0x40078654) and the A0StP is in the kernel heap
(1335981392 = 0x4fa17550):
# cat /proc/self/stat
51 (cat) R ... 1335981392 1074234964 ...
Fix the definitions of KSTK_EIP() and KSTK_ESP() to use
task_pt_regs(tsk)->ctx rather than (tsk)->thread.kernel_context. This
gets the registers from the user context stored after the thread info at
the base of the kernel stack, which is from the last entry into the
kernel from userland, regardless of where in the kernel the task may
have been interrupted, which results in the following more correct
/proc/<pid>/maps output:
# cat /proc/self/maps
...
0800b000-08070000 r-xp 00000000 00:02 207 /lib/libuClibc-0.9.34-git.so
...
100b0000-100b1000 rwxp 00000000 00:00 0 [heap]
3afff000-3b021000 rwxp 00000000 00:00 0 [stack]
And /proc/<pid>/stat now correctly reports the PC in libuClibc
(134320308 = 0x80190b4) and the A0StP in the [stack] region (989864576 =
0x3b002280):
# cat /proc/self/stat

cfg80211_net_detect_results. However, since there can be an arbitrary number of
frequency results, we should use the loop index of the loop used to add the
frequency results to NL80211_ATTR_SCAN_FREQUENCIES as the type (i.e. nla_type)
for each result attribute, rather than a fixed type.
This change is in line with how nested members are added to
NL80211_ATTR_SCAN_FREQUENCIES in the functions nl80211_send_wowlan_nd and
nl80211_add_scan_req.

If ieee80211_vif_use_channel() fails, we have to clear
sdata->radar_required (which we might have just set).
Failing to do it results in stale radar_required field
which prevents starting new scan requests.

Correct two problems with the error handling when using the netlink
forwarding API: first, the netlink skb is never freed if nla_put()
fails; and second, genlmsg_unicast() can fail if the netlink socket
is full. In the latter case, the corresponding data skb is not counted
as a drop and userspace programs like wmediumd will see TCP stalls
due to lost packets.

git://people.freedesktop.org/~gabbayo/linux into drm-fixes
- Fix a bug that caused 15% CPU performance drop in Kaveri. This was caused
because we overwritten the initialization of the first pipe (out of eight),
which is dedicated to radeon operation. The fix was tested by Michel Dänzer.
This bug was introduced by a patch I prepared (yeah, my bad) and was merged
to 3.19-rc6. Therefore, I also marked it as Cc:stable.
- Fix sparse warning

drm/tegra: Fixes for v3.20-rc1
This fixes a bit of fallout that was caused by the atomic modesetting
driver conversion and some last-minute changes in the DRM atomic core.
It also fixes a bug exposed by recent changes in the clock framework
which results in non-working HDMI.
