Three regression fixes and one no-lvds quirk update. The regression Egbert
Eich tracked down goes back to 2.6.37 ... ugh. The other two are pretty
minor: One bogus modeset state checker WARN and a patch to prevent X
dying in a SIGBUS after a gpu hang with failed (or not implement as on
gen2/3) gpu reset.

d40ee48acd drm/nv50/kms: use dac loadval from vbios, where it's available
Regression from merging the old nv50/nvd9 code together, and may be
needed to fully fix fdo#64904.

The value is ignored completely by the hardware starting from nva3.

beba44b17d drm/nv84/disp: Fix HDMI audio regression
Code refactoring in commit 8e9e3d2dea
(drm/nv84/disp: move hdmi control into core) disabled HDMI audio on my
nv84 by removing too much old code without adding it in the new one.
This patch adds the missing code within the new code layout resulting in
HDMI audio working again.
It should work on any HDMI head, but due to lacking ahrdware I could
only test the (1st) one.
It also might be possible that similar code is needed for nva3, which I
can't test.

5343a7f8be net_sched: htb: do not mix 1ns and 64ns time units
commit 56b765b79 ("htb: improved accuracy at high rates") added another
regression for low rates, because it mixes 1ns and 64ns time units.

So the maximum delay (mbuffer) was not 60 second, but 937 ms.

Lets convert all time fields to 1ns as 64bit arches are becoming the
norm.

5e71d9d77c net: fix sk_buff head without data area
Eric Dumazet spotted that we have to check skb->head instead
of skb->data as skb->head points to the beginning of the
data area of the skbuff. Similarly, we have to initialize the
skb->head pointer, not skb->data in __alloc_skb_head.

After this fix, netlink crashes in the release path of the
sk_buff, so let's fix that as well.

This bug was introduced in (0ebd0ac net: add function to
allocate sk_buff head without data area).

3a5395b3d5 net: ethernet: xilinx_emaclite: set protocol selector bits when writing ANAR
This patch sets the protocol selector bits (4:0) of the PHY's MII_ADVERTISE
register (ANAR) when writing ADVERTISE_ALL. The protocol selector bits are
indicating IEEE 803.3u support and are fixed / read-only on some PHYs. Not
setting them correctly on others (like TI DP83630) makes the PHY fall back
to 10M HDX mode which should be avoided.

Tested for TI DP83630 PHY on Microblaze platform.

44dbc78ee4 bnx2x: Fix bridged GSO for 57710/57711 chips
It was recently found out that GSO on 57710/57711 was broken, due to packets
being sent without a valid IP checksum.

Commit 057cf65 "bnx2x: Fix GSO for 57710/57711 chips" partially fixed this
issue, but failed to set the correct IP checksum when receiving GSO packets
via bridges, as such packets enter bnx2x_tx_split() and the FW flags needed
to calculate IP checksum were erroneously set in the incorrect
buffer descriptor.

This patch re-enables GSO in said scenario for 57710/57711 chips.

5b61ff43a7 IB/iser: Fix device removal flow
Change the code to destroy the "last opened" rdma_cm id after making
sure we released all other objects (QP, CQs, PD, etc) associated with
the IB device.

Since iser accesses the IB device using the rdma_cm id, we need to
free any objects that are related to the device that is associated
with the rdma_cm id prior to destroying that id.  When this isn't
done, the low level driver that created this device can be unloaded
before iser has a chance to free all the objects and a such a call may
invoke code segment which isn't valid any more and crash.

ef96f7d46a net/mlx4_en: Handle unassigned VF MAC address correctly
When a VF sense they didn't get MAC address, use random one. This will
address the case of administrator not assigning MAC to the VF through
the PF OS APIs and keep udev happy.

5efe5355f2 net/mlx4_core: Return -EPROBE_DEFER when a VF is probed before PF is sufficiently initialized
In the PF initialization, SRIOV is enabled before the PF is fully initialized.
This allows the kernel to probe the newly-exposed VFs before the PF is ready
to handle them (nested probes).

Have the probe method return the -EPROBE_DEFER value in this situation (instead
of the VF probe method retrying its initialization in a loop, and returning -EIO
on failure). When -EPROBE_DEFER is returned by the VF probe method, the kernel
itself will retry the probe after a suitable delay.

Based upon a suggestion by Ben Hutchings <bhutchings@solarflare.com>

bc2bfffc38 spi: hspi: fixup long delay time
Current HSPI driver is using msleep(20) on hspi_status_check_timeout(),
but it was too long delay for SPI device.
Bock-W board SPI access was too slow without this patch.
This patch uses udelay(10) for it.

68c315bb95 spi: spi-xilinx: Remove ISR race condition
The ISR currently consumes the rx buffer data and re-enables transmission
from within interrupt context. This is bad because if the interrupt
occurs again before the ISR exits, the new interrupt will be erroneously
cleared by the still completing ISR.

Simplified the ISR by just setting the completion variable and exiting with
no action. Then just looped the transmit functionality in
xilinx_spi_txrx_bufs().

when instead the form should have been

eeb065582a Input: synaptics - fix sync lost after resume on some laptops
In summary, the symptom is intermittent key events lost after resume
on some machines with synaptics touchpad (seems this is synaptics _only_),
and key events loss is due to serio port reconnect after psmouse sync lost.
Removing psmouse and inserting it back during the suspend/resume process
is able to work around the issue, so the difference between psmouse_connect()
and psmouse_reconnect() is the key to the root cause of this problem.

After comparing the two different paths, synaptics driver has its own
implementation of synaptics_reconnect(), and the missing psmouse_probe()
seems significant, the patch below added psmouse_probe() to the reconnect
process, and has been verified many times that the issue could not be reliably
reproduced.

There are two PS/2 commands in psmouse_probe():

  1. PSMOUSE_CMD_GETID
  2. PSMOUSE_CMD_RESET_DIS

Only the PSMOUSE_CMD_GETID seems to be significant. The
PSMOUSE_CMD_RESET_DIS is irrelevant to this issue after trying
several times.  So we have only implemented this patch to issue
the PSMOUSE_CMD_GETID so far.

53d3b4d777 drm/i915/sdvo: Use &intel_sdvo->ddc instead of intel_sdvo->i2c for DDC.
In intel_sdvo_get_lvds_modes() the wrong i2c adapter record is used
for DDC. Thus the code will always have to rely on a LVDS panel
mode supplied by VBT.
In most cases this succeeds, so this didn't get detected for quite
a while.
