This patch adds the ARCH=arm specific a kgdb backend, originally
written by Deepak Saxena <dsaxena@plexity.net> and George Davis
<gdavis@mvista.com>. Geoff Levand <geoffrey.levand@am.sony.com>,
Nicolas Pitre, Manish Lachwani, and Jason Wessel have contributed
various fixups here as well.
The KGDB patch makes one change to the core ARM architecture such that
the traps are initialized early for use with the debugger or other
subsystems.

Stephen Rothwell points out that this file got deleted (on purpose) by
commit 640c1bce86d1e11ee6a1263fdf6170d3210b1684 ("USB: delete airprime
driver"), but then almost immediately incorrectly resurrected by commit
95da310e66ee8090119596c70ca8432e57f9a97f ("usb_serial: API all change").
Delete it again. If it comes back, we'll need to drive a stake through
its heart.

netif_carrier_{on,off}() handles starting and stopping packet
flow into the driver. So there is no reason to invoke netif_stop_queue()
and netif_wake_queue() in response to link status events.

This patch completely reworks the RX path in order to be
more accurate about what is going on with the MAC.
We no longer read the error from the MLSR register instead read
the descriptor status register which reflects, the error per descriptor.
We now allocate skbs on the fly in r6040_rx, and we handle allocation
failure instead of simply dropping the packet. Remove the
rx_free_desc counter of r6040_private structure since we
allocate skbs in the RX path.
r6040_rx_buf_alloc is now removed and becomes unuseless.

Joseph Fannin <jfannin@gmail.com> and Takashi Iwai <tiwai@suse.de>
noticed that commit 073a345c04b01da0cc5b79ac7be0c7c8b1691ef5
("mv643xx_eth: clarify irq masking and unmasking") broke the
mv643xx_eth build when NETPOLL is enabled, due to it not renaming
one instance of INT_CAUSE_EXT in mv643xx_eth_netpoll(). This patch
takes care of that instance as well.

Rework the RX buffers allocation function so that we do not
leak memory in the case we could not allocate skbs for the
RX path. Propagate the errors to the r6040_up function
where we call the RX buffers allocation function.
Also rename the r6040_alloc_txbufs function to
r6040_init_txbufs, to reflect what it really does.

This patch allows Windows Mobile 6 devices to be used for
tethering -- that is, used as modems. It was requested by
AdamW in kernel bugzilla:
http://bugzilla.kernel.org/show_bug.cgi?id=11119
and Mandriva kernel-discuss list. It is tested and confirmed
to work by Peterl:
http://forum.eeeuser.com/viewtopic.php?pid=323543#p323543
This patch is based on the patch in the above kernel bugzilla,
which is from the usb-rndis-lite tree.

Using multiple cores in the same package to handle received traffic
does not appear to provide a performance benefit. Therefore use CPU
topology information to count CPU packages and use that as the default
number of RX queues and interrupts. We rely on interrupt balancing to
spread the interrupts across packages.

The drivers were touching net queue before it has been started, so
without this patch, the drivers will potentially WARN at
net/core/dev.c:1328.
I don't have the hardware for the drivers below, so this patch is
untested, and thus should be carefully peer reviewed.
tc35815.c
au1000_eth.c
bfin_mac.c
macb.c
^ The four drivers are using phylib, they're calling netif_start_queue()
in open() callback. So trivially remove netif_tx_schedule_all().
Phylib will handle netif_carrier_*().
cpmac.c
fec_mpc52xx.c
fs_enet/fs_enet-main.c
sh_eth.c
^ The same as above, but these were also needlessly calling
netif_carrier_*() functions. So removed queue calls and also remove
carrier calls, since phylib will handle it. fs_enet-main.c also didn't
call netif_start_queue() at open(), this is fixed now.
