Pull networking fixes from David Miller:
"Some holiday bug fixes for 3.13... There is still one bug I'd like to
get fixed before 3.13-final.
The vlan code erroneously assignes the header ops of the underlying
real device to the VLAN device above it when the real device can
hardware offload VLAN handling. That's completely bogus because
header ops are tied to the device type, so they only expect to see a
'dev' argument compatible with their ops.
The fix is the have the VLAN code use a special set of header ops that
does the pass-thru correctly, by calling the underlying real device's
header ops but _also_ passing in the real device instead of the VLAN
device.
That fix is currently waiting some testing.

This patch adjusts the refcount in the walk of the interrupt tree.
When a match is found, there is no need to increase the refcount
on 'out_irq->np' as 'newpar' is already holding a ref. The refcount
balance between 'ipar' and 'newpar' is maintained in the skiplevel:
goto label.
This patch also removes the usage of the device_node variable 'old'
which seems useless after the latest changes.

Thierry Reding confirmed this commit was not needed after all:
"We ended up merging a different address representation for Tegra PCIe
and I've confirmed that reverting this commit doesn't cause any obvious
regressions. I think all other drivers in drivers/pci/host ended up
copying what we did on Tegra, so I wouldn't expect any other breakage
either."
There doesn't appear to be a simple way to support both behaviours, so
reverting this as nothing should be depending on the new behaviour.

This patch corrects a problem in stmmac_ptp.c, functions
stmmac_adjust_time and stmmac_adjust_freq where the incorrect spinlocks
were released. This patch also addresses a problem in stmmac_main,
function stmmac_init_ptp where the capability detection for
advanced timestamping was masked by message masking.
This patch was touch tested using linuxptp, and runs without the previously
observed instabilities. More extensive testing is ongoing.

The sizes chosen for the metadata and grant_copy_op arrays on the guest
receive size are wrong;
- The meta array is needlessly twice the ring size, when we only ever
consume a single array element per RX ring slot
- The grant_copy_op array is way too small. It's sized based on a bogus
assumption: that at most two copy ops will be used per ring slot. This
may have been true at some point in the past but it's clear from looking
at start_new_rx_buffer() that a new ring slot is only consumed if a frag
would overflow the current slot (plus some other conditions) so the actual
limit is MAX_SKB_FRAGS grant_copy_ops per ring slot.
This patch fixes those two sizing issues and, because grant_copy_ops grows
so much, it pulls it out into a separate chunk of vmalloc()ed memory.

There are inconsistencies wrt. feature propagation/inheritance between
macvlan and the underlying interface.
When a feature is turned off on the real device before a macvlan is
created on top, these will remain enabled on the macvlan device, whereas
turning off the feature on the lower device after macvlan creation the
kernel will propagate the changes to the macvlan.
The second issue is that, when propagating changes from underlying device
to the macvlan interface, macvlan can erronously lose its NETIF_F_LLTX flag,
as features are anded with the underlying device.
However, LLTX should be kept since it has no dependencies on physical
hardware (LLTX is set on macvlan creation regardless of the lower
device properties, see 8ffab51b3dfc54876f145f15b351c41f3f703195
(macvlan: lockless tx path).
The LLTX flag is now forced regardless of user settings in absence of
layer2 hw acceleration (a6cc0cfa72e0b6d9f2c8fd858aa,
net: Add layer 2 hardware acceleration operations for macvlan devices).
Use netdev_increment_features to rebuild the feature set on capability
changes on either the lower device or on the macvlan interface.
As pointed out by Ben Hutchings, use netdev_update_features on
NETDEV_FEAT_CHANGE event (it calls macvlan_fix_features/netdev_features_change
if needed).

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"

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.

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.

Adds API cxgb4_select_ntuple so as to enable Upper Level Drivers to correctly
calculate the tuple fields.
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
cxgb4_select_ntuple() to calculate and return u64 values.

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.
