066a1a5fca KVM: add kvm_para_available to asm-generic/kvm_para.h
According to include/uapi/linux/kvm_para.h architectures should define
kvm_para_available, so add an implementation to asm-generic/kvm_para.h
which just returns false.

This fixes intel8x0.c build failure on mips with KVM enabled.

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.

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.

here are there fixes for the v3.10 release cycle:

The first patch by Jonas Peterson and Olivier Sobrie fixes the reception of CAN
frames on Kvaser's "USBcan Pro" and "USBcan R" type hardware.

The last two patches by Olivier Sobrie (for esd_usb2) and me (for peak_usb)
change the memory handling for the USB messages from stack to kmalloc(), as
memory used for DMA should not be allocated on stack.

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.

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().
