"The interesting bug fix is support for the upcoming "4.2" release of
the Tilera hypervisor, which by default launches Linux at privilege
level 2 instead of 1. The fix lets new and old hypervisors and
Linuxes interoperate more smoothly, so I've tagged it for
stable@kernel.org so that older Linuxes will be able to boot under the
newer hypervisor."

While cleaning RX queues, the CQ DB may be rung several times (with rearm)
while waiting for the flush compl. Each CQ-notify with rearm can result in
an event. The EQ may get full resulting in a HW error.
Fix this by not re-arming the CQ while notifying a valid completion.
Also, there's no need to wait for 1ms after destroying RXQ, as the code in
be_rx_cq_clean() waits for the flush compl to arrive.

When unloading the driver that drives an EISA board, a message similar to the
following one is displayed:
Trying to free nonexistent resource <0000000000013000-000000000001301f>
Then an user is unable to reload the driver because the resource it requested in
the previous load hasn't been freed. This happens most probably due to a typo in
vortex_eisa_remove() which calls release_region() with 'dev->base_addr' instead
of 'edev->base_addr'...

Some ancient pHyp versions used to create a 8 bytes local-mac-address
property in the device-tree instead of a 6 bytes one for veth.
The Linux driver code to deal with that is an insane hack which also
happens to break with some choices of MAC addresses in qemu by testing
for a bit in the address rather than just looking at the size of the
property.
Sanitize this by doing the latter instead.

After recent 86a9bad3 (net: vlan: add protocol argument to packet
tagging functions) my sky2 started to crash on receive of tagged
frames, with backtrace similar to
#CRASH!!!
vlan_do_receive
__netif_receive_skb_core
__netif_receive_skb
netif_receive_skb
sky2_poll
...
__net_rx_action
__do_softirq
The problem turned out to be:
1) sky2 copies small packets from ring on RX, and in its
receive_copy() skb header is copied manually field, by field, and
only for some fields;
2) 86a9bad3 added skb->vlan_proto, which vlan_untag() or
__vlan_hwaccel_put_tag() set, and which is later used in
vlan_do_receive().
That patch updated copy_skb_header() for newly introduced
skb->vlan_proto, but overlooked the need to also copy it in sky2's
receive_copy().
Because of 2, we have the following scenario:
- frame is received and tagged in a ring, by sky2_rx_tag(). Both
skb->vlan_proto and skb->vlan_tci are set;
- later skb is decided to be copied, but skb->vlan_proto is
forgotten and becomes 0.
- in the beginning of vlan_do_receive() we call
__be16 vlan_proto = skb->vlan_proto;
vlan_dev = vlan_find_dev(skb->dev, vlan_proto, vlan_id);
which eventually invokes
vlan_proto_idx(vlan_proto)
and that routine BUGs for everything except ETH_P_8021Q and
ETH_P_8021AD.
Oops.
Fix it.
P.S.
Stephen, I wonder, why copy_skb_header() is not used in
sky2.c::receive_copy() ? Problems, where receive_copy was updated field
by field showed several times already, e.g.
3f42941b (sky2: propogate rx hash when packet is copied)
e072b3fa (sky2: fix receive length error in mixed non-VLAN/VLAN traffic)

Pull i2c changes from Wolfram Sang:
- an arbitration driver. While the driver is quite simple, it caused
discussion if we need additional arbitration on top of the one
specified in the I2C standard. Conclusion is that I accept a few
generic mechanisms, but not very specific ones.
- the core lost the detach_adapter() call. It has no users anymore and
was in the way for other cleanups. attach_adapter() is sadly still
there since there are users waiting to be converted.
- the core gained a bus recovery infrastructure. I2C defines a way to
recover if the data line is stalled. This mechanism is now in the
core and drivers can now pass some data to make use of it.
- bigger driver cleanups for designware, s3c2410
- removing superfluous refcounting from drivers

In CPSW NAPI, after processing all interrupts IRQ is enabled and then book
keeping irq_enabled is updated. In random cases when a packet is transmitted
or received between processing packets and IRQ enabled, then just after
enabled IRQ and before irq_enabled is updated, ISR is called so IRQs are
not disabled as irq_enabled is still false and CPU gets locked in CPSW ISR.
By changing the sequence as update the irq_enabled and then enable IRQ
fixes the issue. This issue is not captured always as it is a timing issue
whether Tx or Rx IRQ is invoked between packet processing and enable IRQ.

Tilera hypervisor launches Linux at PL2 instead.
This commit makes the KERNEL_PL option default to 2 for tilegx, while
still saying at 1 for tilepro, which doesn't have an updated hypervisor.
It also explains how and when you might want to choose another value.
In addition, we change a small buglet in the on-chip Ethernet driver,
where we were failing to use the KERNEL_PL constant in an API call.
To make the transition cleaner, this change also provides the updated
hv_init() API for the new hypervisor that supports announcing Linux's
compiled-in PL, so the hypervisor can generate a suitable error in the
case of a mismatched hypervisor and Linux binary.

Here is a collection of fixes (and some intermixed cleanups) that were
considered less important and thus not included in the later parts of
the 3.9-rc cycle.
It's a bit all over the map, contents wise. A series of ux500 fixes
and cleanups, a bunch of various fixes for OMAP and tegra, and some for
Freescale i.MX and even Qualcomm MSM.
Note that there's also a patch on this branch to globally turn off
-Wmaybe-uninitialized when building with -Os. It's been posted several
times by Arnd and no dissent was raised, but nobody seemed interested
to pick it up. So here it is, as the topmost patch.

When the bnx2x driver reads the port configuration - mask irrelevant bits.
Without this change, the unintended bits may cause the driver to needlessly
toggle the link, as a comparison in the link flap avoidance flow will show
that the old link did not advertise the same capabilities and thus cannot

With the commit a11fbba (net/cpsw: fix irq_disable() with threaded interrupts)
from Sebastian Siewior, a kernel warning is generated as below. This warning
is generated as the irq_enabled is not initialized for the primary interface
and in probe it is initialized for the second interface. This patch moves
irq_enabled initialization from second interface to primary interface.

The venerable 3c509 driver only sets its device parent in one case, the ISAPnP one.
It does this with the SET_NETDEV_DEV function. It should register with the device
hierarchy in two additional cases: standard (non-PnP) ISA and EISA.
- Currently they appear here:
/sys/devices/virtual/net/eth0 (standard ISA)
/sys/devices/virtual/net/eth1 (EISA)
- Rather, they should instead be here:
/sys/devices/isa/3c509.0/net/eth0 (standard ISA)
/sys/devices/pci0000:00/0000:00:07.0/00:04/net/eth1 (EISA)
