ba3211ccd0 bonding:reset backup and inactive flag of slave
Eduard Sinelnikov (eduard.sinelnikov@gmail.com) found that if we change
bonding mode from active backup to round robin, some slaves are still keeping
"backup", and won't transmit packets.

As Jay Vosburgh(fubar@us.ibm.com) pointed out that we can work around that by
removing the bond_is_active_slave() check, because the "backup" flag is only
meaningful for active backup mode.

But if we just simply ignore the bond_is_active_slave() check,
the transmission will work fine, but we can't maintain the correct value of
"backup" flag for each slaves, though it is meaningless for other mode than
active backup.

I'd like to reset "backup" and "inactive" flag in bond_open,
thus we can keep the correct value of them.

As for bond_is_active_slave(), I'd like to prepare another patch to handle it.

V2:
Use C style comment.
Move read_lock(&bond->curr_slave_lock).
Replace restore with reset, for active backup mode, it means "restore",
but for other modes, it means "reset".

951f2f960e drivers/net/can/sja1000/plx_pci.c: eliminate double free
In this code, the failure_cleanup label calls the function
plx_pci_del_card, which frees everything in the card->net_dev array.  dev
is placed in this array immediately after allocation, so the two subsequent
jumps to failure_cleanup should not also call free_sja1000dev, but the
second one does.

If plx_pci_check_sja1000 fails, then free_sja1000dev is also called on
dev.  Because dev is already in the card->net_dev array, this implies that
when plx_pci_del_card is later called, it may get freed again.  So that
entry is reset to NULL after the free.

Finally, if there is a problem with one channel, there will be a hole in the
array.  card->channels counts the number of channels that have succeeded,
and does not keep track of the index of the largest element in the array
that is valid.  So the loop in plx_pci_del_card is changed to go up to
PLX_PCI_MAX_CHAN, which is only 2.

75bc8ef528 usbnet/cdc_ncm: Don't use stack variables for DMA
The cdc_ncm driver still has a few places where stack variables are
passed to the cdc_ncm_do_request function.  This triggers a stack trace in
lib/dma-debug.c if the CONFIG_DEBUG_DMA_API option is set.

Adjust these calls to pass parameters that have been allocated with
kzalloc.

f6957f88e5 vmxnet3: Don't enable vlan filters in promiscuous mode.
The vmxnet3 driver enables vlan filters if filtering is enabled for
any vlan.  In promiscuous mode the filter table is cleared to in
order to disable filtering.  However, if a vlan device is subsequently
created that vlan will be added to the filter, re-engaging it.  As a
result, not only do we not see all the vlans in promiscuous mode, we
don't even see vlans for which a filter was previously created.

c6e7f51e73 e1000e: workaround invalid Tx/Rx tail descriptor register write
When the Manageability Engine (ME) is enabled on 82579, it periodically
accesses some MAC CSR registers.  There is an arbiter in hardware which
prevents simultaneous access of these registers by the host software, i.e.
the driver.  There is a hardware bug in the aribter that signals a host
access of the registers later than it actually happens.  A write of the
Transmit or Receive Descriptor Tail register could result in an incorrect
value if the driver and ME perform simultaneous accesses which could result
in an access to an invalid memory address.  This would return an
Unsupported Request which could hang the hardware.  Workaround the issue by
checking the FWSM register bit24 which is set by ME before it accesses the
MAC CSR registers.

0ed013e28f e1000e: workaround for packet drop on 82579 at 100Mbps
The MAC can drop short packets when the PHY detects noise on the line at
100Mbps due to a timing issue.  Workaround the issue by increasing the PLL
counter so the PHY properly recognizes the synchronization pattern from the
MAC.

1d2101a712 e1000e: Spurious interrupts & dropped packets with 82577/8/9 in half-duplex
On 82577/8/9 in half-duplex when a received packet is passed from the PHY
to the MAC, if too many preamble octects are stripped from the packet
before arriving at the MAC, it can be misintrepeted as an in-band message
rather than an actual frame.  For example, if the frame contents resembled
an interrupt request in-band message, it would trigger a false interrupt.
In most cases, the packet is just dropped.

By reducing the number of preamble octets stripped from the beginning of
the frame when passing it from the PHY to the MAC, the MAC will interpret
the frame properly.

An additional uses of the magic PHY_REG(770, 16) have been updated with a
define introduced with this patch.

In each case, the kfree already at the end of the function is also needed
in the error case.

follows: (http://coccinelle.lip6.fr/)

bdc71bc592 ath5k: fix error handling in ath5k_beacon_send
This cleans up error handling for the beacon in case of dma mapping
failure.  We need to free the skb when dma mapping fails instead of
nulling and leaking the pointer, and we should bail out to avoid
giving the hardware the bad descriptor.

Finally, we need to perform the null check after trying to update
the beacon, or else beacons will never be sent after a single
mapping failure.

ehci_bios_handoff() is marked __devinit, `ehci_dmi_nohandoff_table' should be
marked __devinitconst, not __initconst. This fixes the following section
mismatch:

WARNING: vmlinux.o(.devinit.text+0x4f08): Section mismatch in reference from the function ehci_bios_handoff() to the variable .init.rodata:ehci_dmi_nohandoff_table
The function __devinit ehci_bios_handoff() references a variable __initconst ehci_dmi_nohandoff_table.
If ehci_dmi_nohandoff_table is only used by ehci_bios_handoff then annotate ehci_dmi_nohandoff_table with a matching annotation.
