can: remove references to berlios mailinglist
The BerliOS project, which currently hosts our mailinglist, will
close with the end of the year. Now take the chance and remove all
occurrences of the mailinglist address from the source files.

net: remove interrupt.h inclusion from netdevice.h
* remove interrupt.g inclusion from netdevice.h -- not needed
* fixup fallout, add interrupt.h and hardirq.h back where needed.

can: Fix SJA1000 command register writes on SMP systems
The SJA1000 command register is concurrently written in the rx-path to free
the receive buffer _and_ in the tx-path to start the transmission.
The SJA1000 data sheet, 6.4.4 COMMAND REGISTER (CMR) states:
"Between two commands at least one internal clock cycle is needed in
order to proceed. The internal clock is half of the external oscillator
frequency."
On SMP systems the current implementation leads to a write stall in the
tx-path, which can be solved by adding some general locking and some time
to settle the write_reg() operation for the command register.
Thanks to Klaus Hitschler for the original fix and detailed problem
description.
This patch applies on net-2.6 and (with some offsets) on net-next-2.6 .

can: make the number of echo skb's configurable
This patch allows the CAN controller driver to define the number of echo
skb's used for the local loopback (echo), as suggested by Kurt Van
Dijck, with the function:
struct net_device *alloc_candev(int sizeof_priv,
unsigned int echo_skb_max);
The CAN drivers have been adapted accordingly. For the ems_usb driver,
as suggested by Sebastian Haas, the number of echo skb's has been
increased to 10, which improves the transmission performance a lot.

can: sja1000: stop misusing member base_addr of struct net_device
As discussed on the netdev mailing list, the member "base_addr" of
"struct net_device" should not be (mis)used to store the virtual
address to the SJA1000 register area. According to David Miller,
it's only use is to allow ISA and similar primitive bus devices to
have their I/O ports changed via ifconfig. The virtual address is
now stored in the private data structure of the SJA1000 device and
the callback functions use "struct sja1000_priv" instead of the
unneeded "struct net_device".
