This patch adds a auth configfs group context following existing
explict NodeACL and discovery auth within:
/sys/kernel/config/target/iscsi/$TARGETNAME/$TPGT/auth/
This patch allows these attributes to be used for CHAP authentication
an TPG is configured in demo-mode (generate_node_acl=1).
Note this authentication information takes precedence over NodeACL
authentication when struct se_node_acl->dynamic_node_acl is present.

This patch changes ISCSI_OP_TEXT handling of SendTargets=[iqn.,eui.]

This patch moves ISCSI_OP_TEXT PDU buffer sanity checks to
iscsit_process_text_cmd() code, so that it can be shared
with iser-target code.
It adds IFC_SENDTARGETS_ALL + iscsi_cmd->text_in_ptr in order
to save text payload for ISCSI_OP_TEXT_RSP, and updates
iscsit_release_cmd() to assigned memory.

Somehow a naked u16 slipped into the glibc headers on my Ubuntu machine
(i386 2.17-0ubuntu5), breaking compile:
In file included from lguest.c:46:0:
/usr/include/linux/virtio_net.h:188:2: error: unknown type name ‘u16’
We use the kernel-style types anyway, just define them before the includes.
Also remove the advice on adding missing headers: that no longer works.

Commit 55257d72bd1c51f25106350f4983ec19f62ed1fa (virtio-net: fill only rx queues
which are being used) tries to refill on demand when changing the number of
channels by call try_refill_recv() directly, this may race:
- the refill work who may do the refill in the same time
- the try_refill_recv() called in bh since napi was not disabled
Which may led guest complain during setting channels:
virtio_net virtio0: input.1:id 0 is not a head!
Solve this issue by scheduling a refill work which can guarantee the
serialization of refill.

There are missing parts to handle error in drm_open_helper().
The priv->minor, assigned by idr_find() which can return NULL,
should be checked whether it is NULL or not before referencing it.
put_pid(), drm_gem_release(), and drm_prime_destory_file_private()
should be called when error happens after their pair functions are
called. If an error occurs after executing dev->driver->open()
which allocates driver specific per-file private data, then the
private data should be released.

are available
After the removal of rt->n we do not create a neighbour entry at route
insertion time (rt6_bind_neighbour is gone). As long as no neighbour is
created because of "useful traffic" we skip this routing entry because
rt6_check_neigh cannot pick up a valid neighbour (neigh == NULL) and
thus returns false.
This change was introduced by commit
887c95cc1da53f66a5890fdeab13414613010097 ("ipv6: Complete neighbour
entry removal from dst_entry.")
To quote RFC4191:
"If the host has no information about the router's reachability, then
the host assumes the router is reachable."
and also:
"A host MUST NOT probe a router's reachability in the absence of useful
traffic that the host would have sent to the router if it were reachable."
So, just assume the router is reachable and let's rt6_probe do the
rest. We don't need to create a neighbour on route insertion time.
If we don't compile with CONFIG_IPV6_ROUTER_PREF (RFC4191 support)
a neighbour is only valid if its nud_state is NUD_VALID. I did not find
any references that we should probe the router on route insertion time
via the other RFCs. So skip this route in that case.
v2:
a) use IS_ENABLED instead of #ifdefs (thanks to Sergei Shtylyov)

Convert drivers/gpu/drm class to use dev_pm_ops for power management and
remove Legacy PM ops hooks. With this change, drm class registers
suspend/resume callbacks via class->pm (dev_pm_ops) instead of Legacy
class->suspend/resume. When __device_suspend() runs call-backs, it will
find class->pm ops for the drm class.
drm_class_suspend() hook calls driver legacy ops with the state information.
e.g: drm_class_suspend() calls into driver suspend routines
via drm_dev->driver->suspend(drm_dev, state).
Once drm_class_suspend() is converted to dev_pm_ops, it will no longer
have access to pm_transition which it has to pass into driver legacy
suspend calls. A new freeze and suspend hooks are added to address the not
having access to the state information. The new freeze and suspend hooks
simply call __drm_class_suspend() with the appropriate pm state information.
__drm_class_suspend() is the original suspend hook with a new name.

git://people.freedesktop.org/~danvet/drm-intel into drm-next
Pile of fixes for 3.11. A bit large in patch count, but that's simply due
to two fixes being split up into really small parts. Also I've included a
few more vlv patches than I'd have included for other platforms. But since
vlv is officially supported for the first time only in 3.11 that shouldn't
result in unbearable risks.
Highlights:
- ghost eDP fixes for hsw from Paulo
- fix PCH detection in virtualized enviroments (Rui Guo)
- duct-tape dma sg construction when swiotlb is in use (Konrad), dupe with
a patch in your drm-fixes branch
- fix sdvo hotplug on i965g
- tune down a bunch of dmesg ERRORs which can be hit under normal
conditions
- detect invalid pitches for tiled scanout buffers (Chris)
- a pile of vlv fixes from Ville: rps improvements, fixes for the dpll
LPF, fixup the sprite mmio offsets
- fix context size on hsw (Ben)
- locking fixes for the hotplug code, specifically the storm handling
- fix get_config on CPT (Xiong Zhang)
- Fix the domain tracking when an unlocked seqno wait was interrupt
(Chris), this seems to explain tons of little corruption bugs in the
ddx. Chris also added a nice igt to exercise this.
- work around stack-corrupting vnsprintf in our error state dumper

commit eea86af6b1e18d ("net: sock: adapt SOCK_MIN_RCVBUF and
SOCK_MIN_SNDBUF") forgot the sk_buff alignment taken into account
in __alloc_skb() : skb->truesize = SKB_TRUESIZE(size);
While above commit fixed the sender issue, the receiver is still
dropping the second packet (on loopback device), because the receiver
socket can not really hold two skbs :
First packet truesize already is above sk_rcvbuf, so even TCP coalescing
cannot help.
On a typical 64bit build, each tcp skb truesize is 2304, instead of 2272

Power-up timing
The DS2408 is sensitive to the power-on slew rate and can inadvertently
power up with a test mode feature enabled. When this occurs, the P0 port
does not respond to the Channel Access Write command. For most reliable
operation, it is recommended to disable the test mode after every power-on
reset using the Disable Test Mode sequence shown below. The 64-bit ROM
code must be transmitted in the same bit sequence as with the Match ROM
command, i.e., least significant bit first. This precaution is
recommended in parasite power mode (VCC pin connected to GND) as well as
with VCC power.
Disable Test Mode:

Instead of allocating a struct pps_gpio_platform_data in the DT case,
store the necessary information in struct pps_gpio_device_data itself.
This avoids an additional allocation and the ifdef. It also gets rid of
some indirection.
Also use dev_err instead of pr_err in the changed code.
