Execute "ethtool -L eth0 combined 0" in guest, if multiqueue
is enabled, virtnet_send_command() will return -EINVAL error,
there is a validation in QEMU.
But if multiqueue is disabled, virtnet_set_queues() will just
return zero (success). We should return error for this situation.

There were occasional ADSP crash during reboot testing:
[ 11.883364] BUG: unable to handle kernel paging request at ffffc90121700000
[ 11.883380] IP: [<ffffffffc024d8bc>] sst_module_insert_fixed_block+0x24f/0x26d [snd_soc_sst_dsp]
[ 11.883397] PGD 7800b067 PUD 0
[ 11.883405] Oops: 0002 [#1] SMP
[ 11.886418] gsmi: Log Shutdown Reason 0x03
The virtual address, ffffc90121700000, was out of range. The virtual
address is calculated by adding LPE base address with an offset:
sst_memcpy32(dsp->addr.lpe + data->offset, data->data, data->size);
The offset is calculated in sst_byt_parse_module, by subtraction of
two virtual addresses dsp->addr.fw_ext and dsp->addr.lpe:
block_data.offset = block->ram_offset + (dsp->addr.fw_ext - dsp->addr.lpe);
These virtual addresses are assigned by kernel from ioremap:
sst->addr.lpe = ioremap(pdata->lpe_base, pdata->lpe_size);
sst->addr.fw_ext = ioremap(pdata->fw_base, pdata->fw_size);
In current driver code, offset is defined as unsigned int32:
struct sst_module_data {
...
u32 offset; /* offset in FW file */
};
Most of the time kernel assigned virtual addresses with addr.fw_ext
greater than addr.lpe. But sometimes it was the other way round.
Fix the problem by declaring offset as signed int32_t.

Implement a recv budget so that in cases of high traffic we still allow other
taskets to get processed.
Without this, we can encounter a host of issues during high wireless traffic
reception depending on system load including rcu stall's detected (ARM),
soft lockups, failure to service critical tasks such as watchdog resets,
and triggering of the tx stuck tasklet.
The same thing was proposed previously by Ben:
http://www.spinics.net/lists/linux-wireless/msg112891.html
The only difference here is that I make sure only processed packets are counted
in the budget by checking at the end of the rx loop.

The AS3722_GPIO_INV bit will always be blindly overwritten by
as3722_pinctrl_gpio_set_direction() and will be ignored when
setting the value of the GPIO in as3722_gpio_set() since the
enable_gpio_invert flag is never set. This will cause an
initially inverted GPIO to toggle when requested as an output,
which could be problematic if, for example, the GPIO controls
a critical regulator.
Instead of setting up the enable_gpio_invert flag, just leave
the invert bit alone and check it before setting the GPIO value.

File-private locks have been merged into Linux for v3.15, and *now*
people are commenting that the name and macro definitions for the new
file-private locks suck.
...and I can't even disagree. The names and command macros do suck.
We're going to have to live with these for a long time, so it's
important that we be happy with the names before we're stuck with them.
The consensus on the lists so far is that they should be rechristened as
"open file description locks".
The name isn't a big deal for the kernel, but the command macros are not
visually distinct enough from the traditional POSIX lock macros. The
glibc and documentation folks are recommending that we change them to
look like F_OFD_{GETLK|SETLK|SETLKW}. That lessens the chance that a
programmer will typo one of the commands wrong, and also makes it easier
to spot this difference when reading code.
This patch makes the following changes that I think are necessary before
v3.15 ships:
1) rename the command macros to their new names. These end up in the uapi
headers and so are part of the external-facing API. It turns out that
glibc doesn't actually use the fcntl.h uapi header, but it's hard to
be sure that something else won't. Changing it now is safest.
2) make the the /proc/locks output display these as type "OFDLCK"

commit 6375b768a9850b6154478993e5fb566fa4614a9c
Author: Ville Syrjälä <ville.syrjala@linux.intel.com>
Date: Mon Mar 3 11:33:36 2014 +0200
drm/i915: Reject >165MHz modes w/ DVI monitors
the driver started to filter out display modes which exceed the
single-link DVI 165Mz dotclock limits when the monitor doesn't report
itself as being HDMI compliant. The intent was to filter out all
EDID derived modes that require dual-link DVI to operate since we
don't support dual-link.
However the patch went a bit too far and also causes the driver to reject
such modes even when specified by the user. Normally we don't check the
sink limitations when setting a mode from the user. This allows the user
to specify any mode whether the sink reports to support it or not. This
can be useful since often the sinks support more modes than they report
in the EDID.
So relax the checks a bit, and apply the single-link DVI dotclock limit
only when filtering the mode list, and ignore the limit when setting
a user specified mode.

but that is impossible after commit 8651f97bd951d (PM / cpuidle:

paused in dpm_suspend_noirq() and resumed in dpm_resume_noirq().

This patch fixes a corner case in the previous USB Deadlock fix patch (12023e7
[SCSI] Fix USB deadlock caused by SCSI error handling).
The scenario is abort command, set flag, abort completes, send TUR, TUR
doesn't return, so we now try to abort the TUR, but scsi_abort_eh_cmnd()
will skip the abort because the flag is set and move straight to reset.

USB requires that every command be aborted first before we escalate to reset.
In particular, USB will deadlock if we try to reset first before aborting the
command.
Unfortunately, the flag we use to tell if a command has already been aborted:
SCSI_EH_ABORT_SCHEDULED is not cleared properly leading to cases where we can
requeue a command with the flag set and proceed immediately to reset if it
fails (thus causing USB to deadlock).
Fix by clearing the SCSI_EH_ABORT_SCHEDULED flag if it has been set. Which
means this will be the second time scsi_abort_command() has been called for
the same command. IE the first abort went out, did its thing, but now the
same command has timed out again.
So this flag gets cleared, and scsi_abort_command() returns FAILED, and _no_
asynchronous abort is being scheduled. scsi_times_out() will then proceed to
call scsi_eh_scmd_add(). But as we've cleared the SCSI_EH_ABORT_SCHEDULED
flag the SCSI_EH_CANCEL_CMD flag will continue to be set, and the command will
be aborted with the main SCSI EH routine.

We're seeing a case where the contents of scmd->result isn't being reset after
a SCSI command encounters an error, is resubmitted, times out and then gets
handled. The error handler acts on the stale result of the previous error
instead of the timeout. Fix this by properly zeroing the scmd->status before
the command is resubmitted.

This series contains updates to e1000e, igb, ixgbe and i40e.
Most notably are Jakub's patches to clean up the Rx time stamping
code for ixgbe and the fix up of debug messages with proper termination.
Jesse's i40e patch fixes an issue reported by Eric Dumazet that the
i40e driver was allowing the hardware to replicate the PSH flag on
all segments of a TSO operation. With this fix, we are now configuring
the CWR bit to only be set in the first packet of a TSO and we
enable TSO_ECN in order to advertise to the stack that we do the right
thing on the wire.

Tests have shown that when a power-up transition is followed by other
PHY operations too quickly, the USB port appears dead. Waiting 1ms fixes
this problem.

This patch reduce unecessary NETTX softirq call caused by
free skb header. You will see this softirq comes twice while
there is only one TX packet to be transmitted.
So using dev_kfree_skb() instead of dev_kfree_skb_any() to
avoid this problem.

Patch
commit 0479633686d370303e3430256ace4bd5f7f138dc
Author: Christoph Hellwig <hch@infradead.org>
Date: Thu Feb 20 14:20:55 2014 -0800
[SCSI] do not manipulate device reference counts in scsi_get/put_command
Introduced a use after free:I in the kill case of scsi_prep_return we have to
release our device reference, but we do this trying to reference the just
freed command. Use the local sdev pointer instead.
