Certain features need to be enabled after ring tests
(e.g., powergating, etc.). Add a function pointer
to split out late enable features.

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"

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.

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.

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.

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.

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).

Adds API cxgb4_select_ntuple so as to enable Upper Level Drivers to correctly

Adds constant definitions for TP_VLAN_PRI_MAP for the Compressed
Filter Tuple field widths and structures and uses them.
Also, the CPL Parameters field for T5 is 40 bits so we need to prototype

IPv6 uses 2 TIDs with CLIP enabled and 4 TIDs without CLIP.
Currently we are incrementing STIDs in use by 1 for both IPv4 and IPv6 which
is wrong.
Further, driver currently does not have interface to query if CLIP is programmed
for particular IPv6 address. So, in this patch we increment/decrement TIDs in use
by 4 for IPv6 assuming absence of CLIP. Such assumption keeps us on safe side and
we don't end up allocating more stids for IPv6 than actually supported.

We were creating LE Workaround Server Filters without specifying
IPPROTO_TCP (6) in the filters (when F_PROTOCOL is set in TP_VLAN_PRI_MAP).
This meant that UDP packets with matching IP Addresses/Ports would get
caught up in the filter and be delivered to ULDs like iw_cxgb4.
So, include the protocol information in the server filter properly.

When creating offload server entries, an IPv6 passive connection request
can trigger a reply with a null STID, whereas the driver would expect
the reply 'STID to match the value used for the request.
This happens due to h/w limitation on T4 and T5.
This patch ensures that STID 0 is never used if the stid range starts
from zero.
