Using bit fields is dangerous on ppc64/sparc64, as the compiler [1]
uses 64bit instructions to manipulate them.
If the 64bit word includes any atomic_t or spinlock_t, we can lose
critical concurrent changes.
This is happening in af_unix, where unix_sk(sk)->gc_candidate/
gc_maybe_cycle/lock share the same 64bit word.
This leads to fatal deadlock, as one/several cpus spin forever
on a spinlock that will never be available again.
A safer way would be to use a long to store flags.
This way we are sure compiler/arch wont do bad things.
As we own unix_gc_lock spinlock when clearing or setting bits,
we can use the non atomic __set_bit()/__clear_bit().
recursion_level can share the same 64bit location with the spinlock,
as it is set only with this spinlock held.

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
be retained.

Currently, in menuconfig, Netlink's new mmaped IO is the very first
entry under the ``Networking support'' item and comes even before
``Networking options'':
[ ] Netlink: mmaped IO

...
Lets move this into ``Networking options'' under netlink's Kconfig,
since this might be more appropriate. Introduced by commit ccdfcc398
(``netlink: mmaped netlink: ring setup'').

This resulted from my commit ca99ca14c which introduced a mutex_trylock
operation in a path that could execute in interrupt context. When mutex
debugging is enabled, the above warns the user when we are in fact
exectuting in interrupt context
interrupt context.
After some discussion, It seems that a semaphore is the proper mechanism to use
here. While mutexes are defined to be unusable in interrupt context, no such
condition exists for semaphores (save for the fact that the non blocking api
calls, like up and down_trylock must be used when in irq context).

This reverts commit d2d2d87dfd1a25ee270994c5b9e3eb4690428d32
("bnx2x: allow nvram test to run when device is down").
Since it makes access to the device in D3 state possible.
More work is required to make sure device is not set to D3
during ifdown. Until this is done the nvram-test should simply
exit if device is down like it did before.

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.

On Renesas R-Car based development boards, although a MAC address is printed on
all the Ethernet port labels, U-Boot doesn't write a valid MAC address to the
Ether MAHR/MALR registers (there's no storage provided for the Ether MAC address
either), so we have to resort to using a random MAC address...

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)
Tested on ISA and EISA boards.

because *off is not reset between each skb_queue_walk().
This patch fixes this so that the behavior is the same as peeking with no
offset on an empty queue: the caller blocks.

"77c1090 net: fix infinite loop in __skb_recv_datagram()" (v3.8) introduced a
regression:
After that commit, recv can no longer peek beyond a 0-sized skb in the queue.
__skb_recv_datagram() instead stops at the first skb with len == 0 and results
in the system call failing with -EFAULT via skb_copy_datagram_iovec().
When peeking at an offset with 0-sized skb(s), each one of those is received
only once, in sequence. The offset starts moving forward again after receiving
datagrams with len > 0.

Change MAC802154_CHAN_NONE from ~(u8)0 to 0xff, or the comparison in
mac802154_wpan_xmit() for ``chan == MAC802154_CHAN_NONE'' will not
succeed.
This bug can be boiled down to ``u8 foo = 0xff; if (foo == ~(u8)0)
[...] else [...]'' where the condition will always take the else

If gcc (e.g. 4.1.2) decides not to inline vsock_init_tables(), this will
cause a section mismatch:
WARNING: net/vmw_vsock/vsock.o(.text+0x1bc): Section mismatch in reference from the function __vsock_core_init() to the function .init.text:vsock_init_tables()
The function __vsock_core_init() references
the function __init vsock_init_tables().
This is often because __vsock_core_init lacks a __init
annotation or the annotation of vsock_init_tables is wrong.
This may cause crashes if VSOCKETS=y and VMWARE_VMCI_VSOCKETS=m.

When we call vsock_core_init to init VSOCK the second time,
vsock_device.minor still points to the old dynamically allocated minor

asking for a static one. However, when other user call misc_register to
allocate a dynamic minor number, it will give the one used by
vsock_core_init(), causing this:

primary_slave & curr_active_slave are not cleaned on enslave failure")
I didn't account for the use of curr_active_slave without curr_slave_lock
and since there are such users, we should hold bond->lock for writing while
setting it to NULL (in the NULL case we don't need the curr_slave_lock).
Keeping the bond lock as to avoid the extra release/acquire cycle.

In scenarios in which a previous driver was removed without proper cleanup
(e.g., kdump), it is possible for the chip to generate an interrupt without
any apparent reason once interrupts are requested.
Due to an erroneous initialization of resources, some of the bnx2x structs
which are required for interrupt handling are initialized only after an
interface's interrupt is requested from the OS.
As a result, once such a spurious interrupt occurs, it will cause a NULL
pointer dereference - the driver will access those structs in its interrupt
handling routine.
This patch change the interrupt request scheme so that bnx2x would only
request interrupts from the kernel after it has finished initializing
all the inner structs required for interrupt handling.

commit (3be8fbab tuntap: fix error return code in tun_set_iff()) breaks the
creation of multiqueue tuntap since it forbids to create more than one queues
for a multiqueue tuntap device. We need return 0 instead -EBUSY here since we
don't want to re-initialize the device when one or more queues has been already
attached. Add a comment and correct the return value to zero.

The sockaddr_nfc_llcp struct has as hole between ->sa_family and

information leak.
Also the ->nfc_protocol element wasn't set so I've added that.
"uaddr->sa_family" and "llcp_addr->sa_family" are the same thing but
it's less confusing to use llcp_addr consistently throughout.

efx_mcdi_get_board_cfg() uses a buffer for the firmware response that
is only large enough to hold subtypes for the originally defined set
of NVRAM partitions. Longer responses are truncated, and we may read
off the end of the buffer when copying out subtypes for additional
partitions. In particular, this can result in the MTD partition for
an FPGA bitfile being named e.g. 'eth5 sfc_fpga:00' when it should be
'eth5 sfc_fpga:01'. This means the firmware update tool (sfupdate)
can't tell which bitfile should be written to the partition.
Correct the response buffer size.

Unicast packet might be of type either UNICAST or

In the two cases the header size is different, but the
mechanism checking the TTVN field was assuming it to be
always of the same type (UNICAST), so failing to access the
inner Ethernet header in case of UNICAST4ADDR.
Fix this by passing the real header length as argument.

The ASIC could lockup in the transmit path when it tries
to insert VLAN in a specific ipv6 packet.
1) Identify the packet which can cause this.
2) Check if the firmware provides a workaround to prevent this.
3) If workaround is not present, drop the packet.
4) If the firmware provides a workaround, insert the VLAN tag in the
packet and inform the firmware to skip further VLAN insertions.

For the Bluetooth bits, Gustavo says:
"A few more patches intended for 3.10, the most important one is the support in
btusb for fw loading for the Intel Bluetooth device. Other than that we have
only fixes and clean ups."
For the iwlwifi bits, Johannes says:
"Here are a few more changes for the 3.10 stream, some bugfixes,
adjustments to some powersave parameters and a new device ID."
For the NFC bits, Samuel says:
"This pull request includes Marcel's Kconfig dependency fix on top of the LLCP
code move to net/nfc."
On top of that...Yogesh Ashok Powar provides a few PCI-related mwifiex
updates, Hauke Mehrtens provides a small ssb feature for spurious
tone avoidance on a specific chip, and Larry Finger provides a small
rtlwifi fix related to avoiding false detection of AP loss.
