Alex Deucher e14cd2bbcb drm/radeon/dpm: switch on new late_enable callback
Right now it's called right after enable, but after
reworking the dpm init order, it will get called later
to accomodate loading the smc early, but enabling
thermal interrupts and block powergating later after
the ring tests are complete.

Pull libata fixes from Tejun Heo:
 "There's one interseting commit - "libata, freezer: avoid block device
  removal while system is frozen".  It's an ugly hack working around a
  deadlock condition between driver core resume and block layer device
  removal paths through freezer which was made more reproducible by
  writeback being converted to workqueue some releases ago.  The bug has
  nothing to do with libata but it's just an workaround which is easy to
  backport.  After discussion, Rafael and I seem to agree that we don't
  really need kernel freezables - both kthread and workqueue.  There are
  few specific workqueues which constitute PM operations and require
  freezing, which will be converted to use workqueue_set_max_active()
  instead.  All other kernel freezer uses are planned to be removed,
  followed by the removal of kthread and workqueue freezer support,
  hopefully.

  Others are device-specific fixes.  The most notable is the addition of
  NO_NCQ_TRIM which is used to disable queued TRIM commands to Micro
  M500 SSDs which otherwise suffers data corruption"

Oleg Nesterov c0c1439541 selinux: selinux_setprocattr()->ptrace_parent() needs rcu_read_lock()
selinux_setprocattr() does ptrace_parent(p) under task_lock(p),
but task_struct->alloc_lock doesn't pin ->parent or ->ptrace,
this looks confusing and triggers the "suspicious RCU usage"
warning because ptrace_parent() does rcu_dereference_check().

And in theory this is wrong, spin_lock()->preempt_disable()
doesn't necessarily imply rcu_read_lock() we need to access
the ->parent.

Only the render backends of the first shader engine were enabled. The others
were erroneously disabled. Enabling the other render backends improves
performance a lot.

Unigine Sanctuary on Bonaire:
  Before: 15 fps
  After:  90 fps

Judging from the fan noise, the GPU was also underclocked when the other
render backends were disabled, resulting in horrible performance. The fan is
a lot noisy under load now.

Dave Airlie 785e15ecef drm/tegra: Changes for v3.14-rc1
This series of changes brings DRM panel support as well as initial code
 to register DSI hosts and peripherals and bind them to DSI drivers. The
 panel and DSI code are both used by the simple panel driver.
 
 The Tegra-specific changes build on top of this work to add support for
 various panels found on Tegra boards. New drivers enable the DSI host
 found on Tegra114 and a special hardware block that calibrates the pads
 used for DSI and CSI. The host1x and the display controller drivers gain
 basic Tegra124 support. To round of the new features, the DRM driver now
 sports a very simple PRIME implementation.
 
 In addition there are various improvements such as the host1x API being
 exported so that client drivers (like the Tegra DRM driver) can be built
 as modules. HDMI now does better power management and legacy FBDEV can
 now be disabled via Kconfig (though it's still enabled by default). A
 few sparse warnings have been squashed and various parts of the code
 have become more robust.

Hannes Frederic Sowa 61e7f09d0f ipv4: consistent reporting of pmtu data in case of corking
We report different pmtu values back on the first write and on further
writes on an corked socket.

Also don't include the dst.header_len (respectively exthdrlen) as this
should already be dealt with by the interface mtu of the outgoing
(virtual) interface and policy of that interface should dictate if
fragmentation should happen.

Instead reduce the pmtu data by IP options as we do for IPv6. Make the
same changes for ip_append_data, where we did not care about options or
dst.header_len at all.

Mugunthan V N db850559a3 drivers: net : cpsw: pass proper device name while requesting irq
During checking the interrupts with "cat /proc/interrupts", it is showing
device name as (null), this change was done with commit id aa1a15e2d where
request_irq is changed to devm_request_irq also changing the irq name from
platform device name to net device name, but the net device is not
registered at this point with the network frame work, so devm_request_irq
is called with device name as NULL, by which it is showed as "(null)" in
"cat /proc/interrupts". So this patch changes back irq name to platform
device name itself in devm_request_irq so that the device name shows as
below.

David S. Miller 015cdf686a Merge branch 'cxgb4'
Hariprasad Shenai says:

====================
This patch series provides miscelleneous fixes for Chelsio T4/T5 adapters
related to server entries and server filter entries.

Also, fixes a bug in ULD (Upper Level Driver) like iw_cxgb4 where-in it
calculates wrong tuple values
on T5 adapter. So, a new API cxgb4_select_ntuple is exported so as to enable
Upper Lever Drivers like iw_cxgb4 to correctly calculate tuple values.

The patches series is created agains David Miller's 'net' tree.
And includes patches on cxgb4 and iw_cxgb4 driver.

Patch 8/8 (RDMA-cxgb4-Use-cxgb4_select_ntuple-to-correctly-calc.patch)
has a build dependency on Patch 5/8
(cxgb4-Add-API-to-correctly-calculate-tuple-fields.patch).

Also, Patch 6/8 (RDMA-cxgb4-Calculate-the-filter-server-TID-properly.patch) has
a functional
dependency on Patch 3/8 (cxgb4-Assign-filter-server-TIDs-properly.patch)

We would like to request this patch series to get merged via David Miller's
'net' tree.

We have included all the maintainers of respective drivers. Kindly review the
change and let us know in case of any review comments.

V2 changes:
 - Removed earlier patch which added sftids_in_use counter. However, the counter
   was actually not used anywhere in this patch series.
   Thanks to David Miller for spotting this.
   We have dropped this patch in V2 and will submit a more complete patch which
   uses sftids_in_use counter later on.
 - Fixed a 'checkpatch.pl --strict' warning on Patch 5/8
   (cxgb4-Add-API-to-correctly-calculate-tuple-fields.patch).
 - Removed some un-used #defines from Patch 5/8
   (cxgb4-Add-API-to-correctly-calculate-tuple-fields.patch).
