dc9c8e218d ALSA: Fix for reading RIRB buffer on NVIDIA aza controller with AMD Phenom cpu
When read RIRB buffer immediately after RIRB interrupt received,
sometimes the data will be "0x0". If we wait for some time, the data
in buffer will be correct. This issue only occurred with AMD Phenom cpu.
So we set this "needs_damn_long_delay" flag.

f24d43c07e udp: complete port availability checking
While looking at UDP port randomization, I noticed it
was litle bit pessimistic, not looking at type of sockets
(IPV6/IPV4) and not looking at bound addresses if any.

We should perform same tests than when binding to a
specific port.

This permits a cleanup of udp_lib_get_port()

78e645cb89 tcpv[46]: fix md5 pseudoheader address field ordering
Maybe it's just me but I guess those md5 people made a mess
out of it by having *_md5_hash_* to use daddr, saddr order
instead of the one that is natural (and equal to what csum
functions use). For the segment were sending, the original
addresses are reversed so buff's saddr == skb's daddr and
vice-versa.

Maybe I can finally proceed with unification of some code
after fixing it first... :-)

If the T4 RTO timer expires many times(timeout), the association will enter

efc968d450 Don't allow splice() to files opened with O_APPEND
This is debatable, but while we're debating it, let's disallow the
combination of splice and an O_APPEND destination.

It's not entirely clear what the semantics of O_APPEND should be, and
POSIX apparently expects pwrite() to ignore O_APPEND, for example.  So
we could make up any semantics we want, including the old ones.

But Miklos convinced me that we should at least give it some thought,
and that accepting writes at arbitrary offsets is wrong at least for
IS_APPEND() files (which always have O_APPEND set, even if the reverse
isn't true: you can obviously have O_APPEND set on a regular file).

So disallow O_APPEND entirely for now.  I doubt anybody cares, and this
way we have one less gray area to worry about.

3bca103a1e [ARM] 5295/1: make ZONE_DMA optional
Most ARM machines don't need a special "DMA" memory zone, and
when configured out, the kernel becomes a bit smaller:

|   text    data     bss     dec     hex filename
|3826182  102384  111700 4040266  3da64a vmlinux
|3823593  101616  111700 4036909  3d992d vmlinux.nodmazone

This is because the system now has only one zone total which effect is
to optimize away many conditionals in page allocation paths.

So let's configure this zone only on machines that need split zones.

d5321e309c bnx2: Update 5706/5708 firmware.
With this new firmware, the driver no longer has to modify the
TCP/IP header fields when transmitting TSO packets.

9f52b564b7 bnx2: Check netif_running() in all ethtool operations.
We need to check netif_running() state in most ethtool operations
and properly handle the !netif_running() state where the chip is
in an uninitailzed state or low power state that may not accept
any MMIO.

74bf4ba3d3 bnx2: Add bnx2_shutdown_chip().
This logic is used in bnx2_close() and bnx2_suspend() and
so should be separated out into a separate function.

70096a561d SLOB: fix bogus ksize calculation fix
This fixes the previous fix, which was completely wrong on closer
inspection. This version has been manually tested with a user-space
test harness and generates sane values. A nearly identical patch has
been boot-tested.

The problem arose from changing how kmalloc/kfree handled alignment
padding without updating ksize to match. This brings it in sync.

64194c31a0 inet: Make tunnel RX/TX byte counters more consistent
This patch makes the RX/TX byte counters for IPIP, GRE and SIT more
consistent.  Previously we included the external IP headers on the
way out but not when the packet is inbound.

The new scheme is to count payload only in both directions.  For
IPIP and SIT this simply means the exclusion of the external IP
header.  For GRE this means that we exclude the GRE header as
well.

e1a8000228 gre: Add Transparent Ethernet Bridging
This patch adds support for Ethernet over GRE encapsulation.
This is exposed to user-space with a new link type of "gretap"
instead of "gre".  It will create an ARPHRD_ETHER device in
lieu of the usual ARPHRD_IPGRE.

Note that to preserver backwards compatibility all Transparent
Ethernet Bridging packets are passed to an ARPHRD_IPGRE tunnel
if its key matches and there is no ARPHRD_ETHER device whose
key matches more closely.

c19e654ddb gre: Add netlink interface
This patch adds a netlink interface that will eventually displace
the existing ioctl interface.  It utilises the elegant rtnl_link_ops
mechanism.

This also means that user-space no longer needs to rely on the
tunnel interface being of type GRE to identify GRE tunnels.  The
identification can now occur using rtnl_link_ops.
