Currently netdev_features_change is called before fcoe tx queues
setup is done, so this patch moves calling of netdev_features_change
after tx queues setup is done in ixgbe_init_interrupt_scheme, so
that real_num_tx_queues is updated correctly on each fcoe enable
or disable.

This allows additional fcoe queues updated correctly in vlan driver
for their correct queue selection.

This patch fixes UDP socket refcnt bugs in the pppol2tp driver.

A bug can cause a kernel stack trace when a tunnel socket is closed.

A way to reproduce the issue is to prepare the UDP socket for L2TP (by
opening a tunnel pppol2tp socket) and then close it before any L2TP
sessions are added to it. The sequence is

Create UDP socket
Create tunnel pppol2tp socket to prepare UDP socket for L2TP
  pppol2tp_connect: session_id=0, peer_session_id=0
L2TP SCCRP control frame received (tunnel_id==0)
  pppol2tp_recv_core: sock_hold()
  pppol2tp_recv_core: sock_put
L2TP ZLB control frame received (tunnel_id=nnn)
  pppol2tp_recv_core: sock_hold()
  pppol2tp_recv_core: sock_put
Close tunnel management socket
  pppol2tp_release: session_id=0, peer_session_id=0
Close UDP socket
  udp_lib_close: BUG

The addition of sock_hold() in pppol2tp_connect() solves the problem.

For data frames, two sock_put() calls were added to plug a refcnt leak
per received data frame. The ref that is grabbed at the top of
pppol2tp_recv_core() must always be released, but this wasn't done for
accepted data frames or data frames discarded because of bad UDP
checksums. This leak meant that any UDP socket that had passed L2TP
data traffic (i.e. L2TP data frames, not just L2TP control frames)
using pppol2tp would not be released by the kernel.

When I initially stumbled upon sequence number problems with PAE frames
in ath9k, I submitted a patch to remove all special cases for PAE
frames and let them go through the normal transmit path.
Out of concern about crypto incompatibility issues, this change was
merged instead:

commit 6c8afef5
Author: Sujith <Sujith.Manoharan@atheros.com>
Date:   Tue Feb 9 10:07:00 2010 +0530

    ath9k: Fix sequence numbers for PAE frames

After a lot of testing, I'm able to reliably trigger a driver crash on
rekeying with current versions with this change in place.
It seems that the driver does not support sending out regular MPDUs with
the same TID while an A-MPDU session is active.
This leads to duplicate entries in the TID Tx buffer, which hits the
following BUG_ON in ath_tx_addto_baw():

    index  = ATH_BA_INDEX(tid->seq_start, bf->bf_seqno);
    cindex = (tid->baw_head + index) & (ATH_TID_MAX_BUFS - 1);

    BUG_ON(tid->tx_buf[cindex] != NULL);

I believe until we actually have a reproducible case of an
incompatibility with another AP using no PAE special cases, we should
simply get rid of this mess.

This patch completely fixes my crash issues in STA mode and makes it
stay connected without throughput drops or connectivity issues even
when the AP is configured to a very short group rekey interval.

When compiling this driver, the compiler throws the following warnings:

drivers/isdn/hardware/eicon/message.c:8426: warning: array subscript is above array bounds
drivers/isdn/hardware/eicon/message.c:8427: warning: array subscript is above array bounds
drivers/isdn/hardware/eicon/message.c:8434: warning: array subscript is above array bounds
drivers/isdn/hardware/eicon/message.c:8435: warning: array subscript is above array bounds
drivers/isdn/hardware/eicon/message.c:8436: warning: array subscript is above array bounds
drivers/isdn/hardware/eicon/message.c:8447: warning: array subscript is above array bounds

This arises from the particular semantics the driver is using to write to
the nlc array (static byte[256]).  The array has a length in byte 0
followed by a T30_INFO struct starting at byte 1.

The T30_INFO struct has a number of variable length strings after the
station_id entry, which cannot be explicitly defined in the struct and the
driver accesses them with an array index to station_id beyond the length
of station_id.

This patch merely changes the semantics that the driver uses to access the
entries after the station_id entry to use the original 256 byte nlc array
taking the offset and length of the station_id entry to calculate where to
write in the array, thereby silencing the warning.

Access to fp->tx_bp_prod is protected by __netif_tx_lock,
smp_mb() is not needed for that.

Access to fp->tx_bd_prod is protected by __netif_tx_lock, so we do not
need any barrier for that.

Update of fp->tx_bd_cons in bnx2x_tx_int() is not protected by lock, but
barrier() nor smb_mb() in bnx2x_tx_avail() not guarantee we will see
values that is written on other cpu. Ordering issues between
netif_tx_stop_queue(), netif_tx_queue_stopped(), fp->tx_bd_cons = bd_cons
and bnx2x_tx_avail() are already handled by smp_mb() in bnx2x_tx_int()
and bnx2x_start_xmit().

Since we want to keep ordering of write to fp->bd_tx_cons and
netif_tx_queue_stopped(txq), what is read of txq->state, we have to use
general memory barrier.

The request to create an mccq was being dispatched without
doing a byte swap of num_pages. This byte swap is necessary
for Big Endian systems like PPC. Not having this fix leads
mccq create to fail on BE ASICs running newer version of
firmware, thereby causing driver initialization failure.

The davinci emac driver uses some ARM specific DMA APIs
for cache coherency which have been removed from kernel
with the 2.6.34 merge.

Modify the driver to use the dma_{map, unmap}_single() APIs
defined in dma-mapping.h

Without this fix, the driver fails to compile on Linus's
tree.

Tested on DM365 and OMAP-L138 EVMs.

When the PCI pool changes were added to fix resume failures:

commit 98468efd
e100: Use pci pool to work around GFP_ATOMIC order 5 memory allocation failu

and

commit 70abc8cb
e100: Fix broken cbs accounting due to missing memset.

This introduced a problem that can happen if the TX ring size
is increased.  We need to size the PCI pool using cbs->max
instead of the default cbs->count value.

Commit 6992f533 ("sysfs: Use one lockdep

There's no real need for a pointer to the MADT to be global. The only
function who uses it is map_madt_entry.

This allows us to remove some more ugly #ifdefs.
