The 2.6 latest git build was broken when using the following
configuration options:
CONFIG_NET_EMATCH=n
CONFIG_NET_CLS_FLOW=y
with the following error:
net/sched/cls_flow.c: In function 'flow_dump':
net/sched/cls_flow.c:598: error: 'struct tcf_ematch_tree' has no
member named 'hdr'
make[2]: *** [net/sched/cls_flow.o] Error 1
make[1]: *** [net/sched] Error 2
make: *** [net] Error 2
see the recent post by Li Zefan:
http://www.spinics.net/lists/netdev/msg54434.html
The reason for this crash is that struct tcf_ematch_tree
(net/pkt_cls.h) is empty when CONFIG_NET_EMATCH is not defined.
When CONFIG_NET_EMATCH is defined, the tcf_ematch_tree structure
indeed holds a struct tcf_ematch_tree_hdr (hdr) as flow_dump()
expects.
This patch adds #ifdef CONFIG_NET_EMATCH in flow_dump to avoid this.

This adds support for flushing the chipsets on the 915, 945, 965 and G33
families of Intel chips.
The BIOS doesn't seem to always allocate the BAR on the 965 chipsets
so I have to use pci resource code to create a resource
It adds an export for pcibios_align_resource.
This bumps the AGP interface to 0.103.
Certain Intel chipsets contains a global write buffer, and this can require
flushing from the drm or X.org to make sure all data has hit RAM before
initiating a GPU transfer, due to a lack of coherency with the integrated
graphics device and this buffer.
This just adds generic support to the AGP interfaces, a follow-on patch
will add support to the Intel driver to use this interface.

When a host just goes away (crash, power loss, etc.) without tearing
down its IB connections, it can get stale connection errors when it
tries to reconnect to targets upon rebooting. Retrying the connection
a few times will prevent sysadmins from playing the "which disk(s)
went missing?" game.
This would have made things slightly quicker when tracking down some
of the recent bugs, but it also helps quite a bit when you've got a
large number of targets hanging off a wedged server.

Move up the code that checks for a situation where the remote GID

neighbour (handle gratuitous ARP) or that a bonding fail over has
happened but the neighbour still has a pointer to an ipoib_neigh
created by a different device than the current slave. This will cause
the driver to apply the check also for connected mode neighbours.

In mthca_reg_phys_mr(), we calculate the page size for the HCA
hardware to use to map the buffer list passed in by the consumer.
For example, if the consumer passes in
[0] addr 0x1000, size 0x1000
[1] addr 0x2000, size 0x1000
then the algorithm would come up with a page size of 0x2000 and a list
of two pages, at 0x0000 and 0x2000. Usually, this would work fine
since the memory region would start at an offset of 0x1000 and have a
length of 0x2000.
However, the old code did not take into account the alignment of the
IO virtual address passed in. For example, if the consumer passed in
a virtual address of 0x6000 for the above, then the offset of 0x1000
would not be used correctly because the page mask of 0x1fff would
result in an offset of 0.
We can fix this quite neatly by making sure that the page shift we use
is no bigger than the first bit where the start of the first buffer
and the IO virtual address differ. Also, we can further simplify the
code by removing the special case for a single buffer by noticing that
it doesn't matter if we use a page size that is too big. This allows
the loop to compute the page shift to be replaced with __ffs().
Thanks to Bryan S Rosenburg <rosnbrg@us.ibm.com> for pointing out the
original bug and suggesting several ways to improve this patch.

The IB spec doesn't allow packets to QP0 sent on any other VL than VL15.
Hardware doesn't filter those packets on the send side, so we need to do
this in the driver and firmware.
As eHCA doesn't support QP0, we can just filter out all traffic going to
QP0, regardless of SL or VL.

Paths with hop_limit > 1 indicate that the connection will be routed
between IB subnets. Update the subnet local field in the CM REQ based
on the hop_limit value. In addition, if the path is routed, then set
the LIDs in the REQ to the permissive LIDs. This is used to indicate
to the passive side that it should use the LIDs in the received local
route header (LRH) associated with the REQ when programming the QP.
This is a temporary work-around to the IB CM to support IB router
development until the IB router specification is completed. It is not
anticipated that this work-around will cause any interoperability
issues with existing stacks or future stacks that will properly
support IB routers when defined.
