Merge git://git./linux/kernel/git/davem/net-next
Pull networking changes from David S Miller:
1) Remove the ipv4 routing cache. Now lookups go directly into the FIB
trie and use prebuilt routes cached there.
No more garbage collection, no more rDOS attacks on the routing
cache. Instead we now get predictable and consistent performance,
no matter what the pattern of traffic we service.
This has been almost 2 years in the making. Special thanks to
Julian Anastasov, Eric Dumazet, Steffen Klassert, and others who
have helped along the way.
I'm sure that with a change of this magnitude there will be some
kind of fallout, but such things ought the be simple to fix at this
point. Luckily I'm not European so I'll be around all of August to
fix things :-)
The major stages of this work here are each fronted by a forced
merge commit whose commit message contains a top-level description
of the motivations and implementation issues.
2) Pre-demux of established ipv4 TCP sockets, saves a route demux on
input.
3) TCP SYN/ACK performance tweaks from Eric Dumazet.
4) Add namespace support for netfilter L4 conntrack helpers, from Gao
Feng.
5) Add config mechanism for Energy Efficient Ethernet to ethtool, from
Yuval Mintz.
6) Remove quadratic behavior from /proc/net/unix, from Eric Dumazet.
7) Support for connection tracker helpers in userspace, from Pablo
Neira Ayuso.
8) Allow userspace driven TX load balancing functions in TEAM driver,
from Jiri Pirko.
9) Kill off NLMSG_PUT and RTA_PUT macros, more gross stuff with
embedded gotos.
10) TCP Small Queues, essentially minimize the amount of TCP data queued
up in the packet scheduler layer. Whereas the existing BQL (Byte
Queue Limits) limits the pkt_sched --> netdevice queuing levels,
this controls the TCP --> pkt_sched queueing levels.
From Eric Dumazet.
11) Reduce the number of get_page/put_page ops done on SKB fragments,
from Alexander Duyck.
12) Implement protection against blind resets in TCP (RFC 5961), from
Eric Dumazet.
13) Support the client side of TCP Fast Open, basically the ability to
send data in the SYN exchange, from Yuchung Cheng.
Basically, the sender queues up data with a sendmsg() call using
MSG_FASTOPEN, then they do the connect() which emits the queued up
fastopen data.
14) Avoid all the problems we get into in TCP when timers or PMTU events
hit a locked socket. The TCP Small Queues changes added a
tcp_release_cb() that allows us to queue work up to the
release_sock() caller, and that's what we use here too. From Eric
Dumazet.
15) Zero copy on TX support for TUN driver, from Michael S. Tsirkin.

i2c-i801: Enable IRQ for byte_by_byte transactions
Byte-by-byte transactions are used primarily for accessing I2C devices
with an SMBus controller. For these transactions, for each byte that is
read or written, the SMBus controller generates a BYTE_DONE IRQ. The isr
reads/writes the next byte, and clears the IRQ flag to start the next byte.
On the penultimate IRQ, the isr also sets the LAST_BYTE flag.
There is no locking around the cmd/len/count/data variables, since the
I2C adapter lock ensures there is never multiple simultaneous transactions
for the same device, and the driver thread never accesses these variables
while interrupts might be occurring.
The end result is faster I2C block read and write transactions.
Note: This patch has only been tested and verified by doing I2C read and
write block transfers on Cougar Point 6 Series PCH, as well as I2C read
block transfers on ICH5.

Ultimately we want to enable this feature on at least every device

other devices if we don't get negative feedback.

i2c-i801: Enable IRQ for SMBus transactions
Add a new 'feature' to i2c-i801 to enable using PCI interrupts.
When the feature is enabled, then an isr is installed for the device's
PCI IRQ.
An I2C/SMBus transaction is always terminated by one of the following
interrupt sources: FAILED, BUS_ERR, DEV_ERR, or on success: INTR.
When the isr fires for one of these cases, it sets the ->status variable
and wakes up the waitq. The waitq then saves off the status code, and
clears ->status (in preparation for some future transaction).
The SMBus controller generates an INTR irq at the end of each
transaction where INTREN was set in the HST_CNT register.
No locking is needed around accesses to priv->status since all writes to
it are serialized: it is only ever set once in the isr at the end of a
transaction, and cleared while no interrupts can occur. In addition, the
I2C adapter lock guarantees that entire I2C transactions for a single
adapter are always serialized.
For this patch, the INTREN bit is set only for SMBus block, byte and word
transactions, but not for I2C reads or writes. The use of the DS
(BYTE_DONE) interrupt with byte-by-byte I2C transactions is implemented in
a subsequent patch.
The interrupt feature has only been enabled for COUGARPOINT hardware.
In addition, it is disabled if SMBus is using the SMI# interrupt.

Pull powerpc updates from Benjamin Herrenschmidt:
"Notable highlights:
- iommu improvements from Anton removing the per-iommu global lock in
favor of dividing the DMA space into pools, each with its own lock,
and hashed on the CPU number. Along with making the locking more
fine grained, this gives significant improvements in multiqueue
networking scalability.
- Still from Anton, we know provide a vdso based variant of getcpu
which makes sched_getcpu with the appropriate glibc patch something
like 18 times faster.
- More anton goodness (he's been busy !) in other areas such as a
faster __clear_user and copy_page on P7, various perf fixes to
improve sampling quality, etc...
- One more step toward removing legacy i2c interfaces by using new
device-tree based probing of platform devices for the AOA audio
drivers
- A nice series of patches from Michael Neuling that helps avoiding
confusion between register numbers and litterals in assembly code,
trying to enforce the use of "%rN" register names in gas rather
than plain numbers.
- A pile of FSL updates
- The usual bunch of small fixes, cleanups etc...
You may spot a change to drivers/char/mem. The patch got no comment
or ack from outside, it's a trivial patch to allow the architecture to
skip creating /dev/port, which we use to disable it on ppc64 that
don't have a legacy brige. On those, IO ports 0...64K are not mapped
in kernel space at all, so accesses to /dev/port cause oopses (and
yes, distros -still- ship userspace that bangs hard coded ports such
as kbdrate)."
