skge: fix transmitter flow control
It looks like the skge driver inherited another bug from the sk98lin code.
If I send from 1000mbit port to a machine on 100mbit port, the switch should
be doing hardware flow control, but no pause frames show up in the statistics.
This is the analog of the recent sky2 fixes. The device needs to listen
for multicast pause frames and then not discard them.

sungem_phy: support bcm5461 phy, autoneg.
This version moves the medium variable to the card specific structure and
changes the GMII_* to BCM54XX_* #defines.
This patch adds improved version of enable_fiber for both the 5421 and
the 5461 phy. It is now possible to specify with these wether you want
autonegotiation or not. This is needed for bladecenter switches where
some expect autonegotiation and some dont seem to like this at all.
Depending on this flag it sets phy->autoneg accordingly for the fiber mode.
More importantly it implements proper read_link and poll_link functions
for both phys which can handle both copper and fiber mode by determining
the medium first and then branching to the required functions. For fiber
they all work fine, for copper they are not tested but return the result
of the genmii_* function anyway which is supposed to work.

[XFRM]: Fix oops in xfrm4_dst_destroy()
With 2.6.21-rc1, I get an oops when running 'ifdown eth0' and an IPsec
connection is active. If I shut down the connection before running 'ifdown
eth0', then there's no problem. The critical operation of this script is to
kill dhcpd.
The problem is probably caused by commit with git identifier
4337226228e1cfc1d70ee975789c6bd070fb597c (Linus tree) "[IPSEC]: IPv4 over IPv6

This patch fixes that oops. I don't know the network code of the Linux
kernel in deep, so if that fix is wrong, please change it. But please

Reassign printk levels in selinux kernel code
Below is a patch which demotes many printk lines to KERN_DEBUG from
KERN_INFO. It should help stop the spamming of logs with messages in
which users are not interested nor is there any action that users should
take. It also promotes some KERN_INFO to KERN_ERR such as when there
are improper attempts to register/unregister security modules.
A similar patch was discussed a while back on list:
http://marc.theaimsgroup.com/?t=

[SCTP]: Fix connection hang/slowdown with PR-SCTP
The problem that this patch corrects happens when all of the following
conditions are satisfisfied:
1. PR-SCTP is used and the timeout on the chunks is set below RTO.Max.
2. One of the paths on a multihomed associations is brought down.
In this scenario, data will expire within the rto of the initial
transmission and will never be retransmitted. However this data still
fills the send buffer and is counted against the association as outstanding
data. This causes any new data not to be sent and retransmission to not
happen.
The fix is to discount the abandoned data from the outstanding count and
peers rwnd estimation. This allows new data to be sent and a retransmission
timer restarted. Even though this new data will most likely expire within
the rto, the timer still counts as a strike against the transport and forces
the FORWARD-TSN chunk to be retransmitted as well.

[PATCH] genirq: Mask irqs when migrating them.
move_native_irqs tries to do the right thing when migrating irqs
by disabling them. However disabling them is a software logical
thing, not a hardware thing. This has always been a little flaky
and after Ingo's latest round of changes it is guaranteed to not
mask the apic.
So this patch fixes move_native_irq to directly call the mask and
unmask chip methods to guarantee that we mask the irq when we
are migrating it. We must do this as it is required by
all code that call into the path.
Since we don't know the masked status when IRQ_DISABLED is
set so we will not be able to restore it. The patch makes the code
just give up and trying again the next time this routing is called.

[PATCH] x86_64 irq: Safely cleanup an irq after moving it.
The problem: After moving an interrupt when is it safe to teardown
the data structures for receiving the interrupt at the old location?
With a normal pci device it is possible to issue a read to a device
to flush all posted writes. This does not work for the oldest ioapics
because they are on a 3-wire apic bus which is a completely different
data path. For some more modern ioapics when everything is using
front side bus delivery you can flush interrupts by simply issuing a
read to the ioapic. For other modern ioapics emperical testing has
shown that this does not work.
So it appears the only reliable way to know the last of the irqs from an
ioapic have been received from before the ioapic was reprogrammed is to
received the first irq from the ioapic from after it was reprogrammed.
Once we know the last irq message has been received from an ioapic
into a local apic we then need to know that irq message has been
processed through the local apics.

[PATCH] x86_64 irq: Add constants for the reserved IRQ vectors.
For the ISA irqs we reserve 16 vectors. This patch adds constants for
those vectors and modifies the code to use them. Making the code a
little clearer and making it possible to move these vectors in the future.

[PATCH] x86_64 irq: Remove unnecessary irq 0 setup.
The code in io_apic.c and in i8259.c currently hardcode the same
vector for the timer interrupt so there is no reason for a special
assignment for the timer as the setup for the i8259 already takes care
of this.
