6fecd19851 [NETFILTER]: Add SANE connection tracking helper
This is nf_conntrack_sane, a netfilter connection tracking helper module
for the SANE protocol used by the 'saned' daemon to make scanners available
via network. The SANE protocol uses separate control & data connections,
similar to passive FTP. The helper module is needed to recognize the data
connection as RELATED to the control one.

6b31a515e3 [TG3]: Avoid an expensive divide.
During an oprofile session of linux-2.6.20 on a dual opteron system, I noticed
an expensive divide was done in tg3_poll().

I am using gcc-4.1.1, so the following comment from drivers/net/tg3.c seems
over-optimistic :

/* Do not place this n-ring entries value into the tp struct itself,
  * we really want to expose these constants to GCC so that modulo et
  * al.  operations are done with shifts and masks instead of with
  * hw multiply/modulo instructions.  Another solution would be to
  * replace things like '% foo' with '& (foo - 1)'.
  */
#define TG3_RX_RCB_RING_SIZE(tp)        \
         ((tp->tg3_flags2 & TG3_FLG2_5705_PLUS) ?  512 : 1024)

84ff602efb [ATM]: Fix for crash in adummy_init()
This was reported by Ingo Molnar here,

http://lkml.org/lkml/2006/12/18/119

The problem is that adummy_init() depends on atm_init() , but adummy_init()
is called first.

So I put atm_init() into subsys_initcall which seems appropriate, and it
will still get module_init() if it becomes a module.

Interesting to note that you could crash your system here if you just load
the modules in the wrong order.

f5a6e01c09 [NET]: user of the jiffies rounding code: Networking
This patch introduces users of the round_jiffies() function in the
networking code.

These timers all were of the "about once a second" or "about once
every X seconds" variety and several showed up in the "what wakes the
cpu up" profiles that the tickless patches provide.  Some timers are
highly dynamic based on network load; but even on low activity systems
they still show up so the rounding is done only in cases of low
activity, allowing higher frequency timers in the high activity case.

The various hardware watchdogs are an obvious case; they run every 2
seconds but aren't otherwise specific of exactly when they need to
run.

8a3c3a9727 [TCP]: Check num sacks in SACK fast path
We clear the unused parts of the SACK cache, This prevents us from mistakenly
taking the cache data if the old data in the SACK cache is the same as the data
in the SACK block. This assumes that we never receive an empty SACK block with
start and end both at zero.

6f74651ae6 [TCP]: Seperate DSACK from SACK fast path
Move DSACK code outside the SACK fast-path checking code. If the DSACK
determined that the information was too old we stayed with a partial cache
copied. Most likely this matters very little since the next packet will not be
DSACK and we will find it in the cache. but it's still not good form and there
is little reason to couple the two checks.

Since the SACK receive cache doesn't need the data to be in host order we also
remove the ntohl in the checking loop.

ffbc61117d [PACKET]: Fix skb->cb clobbering between aux and sockaddr
Both aux data and sockaddr tries to use the same buffer which
obviously doesn't work.  We just happen to have 4 bytes free in
the skb->cb if you take away the maximum length of sockaddr_ll.
That's just enough to store the one piece of info from aux data
that we can't generate at recvmsg(2) time.

This is what the following patch does.

8dc4194474 [PACKET]: Add optional checksum computation for recvmsg
This patch is needed to make ISC's DHCP server (and probably other
DHCP servers/clients using AF_PACKET) to be able to serve another
client on the same Xen host.

The problem is that packets between different domains on the same
Xen host only have partial checksums.  Unfortunately this piece of
information is not passed along in AF_PACKET unless you're using
the mmap interface.  Since dhcpd doesn't support packet-mmap, UDP
packets from the same host come out with apparently bogus checksums.

This patch adds a mechanism for AF_PACKET recvmsg(2) to return the
status along with the packet.  It does so by adding a new cmsg that
contains this information along with some other relevant data such
as the original packet length.

I didn't include the time stamp information since there is already
a cmsg for that.

This patch also changes the mmap code to set the CSUMNOTREADY flag
on all packets instead of just outoing packets on cooked sockets.

07b2463046 Revert "Driver core: convert SPI code to use struct device"
This reverts commit 2943ecf2ed.

This should go through the SPI maintainer, it was my fault that it did
not.  Especially as it conflicts with other patches he has pending.

d003e7a1a5 [POWERPC] Add export of vgacon_remap_base
The following macro :
include/asm-powerpc/vga.h:#define VGA_MAP_MEM(x,s) (x + vgacon_remap_base)
is used by drivers/video/console/vgacon.c which can be compiled as a module
(drivers/video/vga16fb.ko).

Therefore, vgacon_remap_base should be exported.

92d4dda333 [POWERPC] Fix comment in kernel/irq.c
kernel/irq.c contains a comment that speaks of -1 and -2 as interrupt
numbers, but this is actually dependent on configuration options now.
Replace by NO_IRQ and NO_IRQ_ENABLED.
