b43: remove wrong probe_resp_plcp write

The tkip hw support uncovered a bug in b43_write_probe_resp_template : it is
writing at the wrong shm offset, it is in the B43_SHM_SH_TKIPTSCTTAK
zone. Remove b43_write_probe_resp_template,  b43_write_probe_resp_plcp
and b43_write_probe_resp_plcp because the probe response offload is
currently not supported by mac80211.

mac80211: fix compilation of mesh (although its disabled)

Mesh is currently disabled on mac80211, its marked
as broken. This patch gets it to compile though,
to account for the mac80211 workqueue changes.
There was a simple typo in the patches for mesh
for the workqueue migration, but we never compile
tested it as we couldn't even select mesh as its
broken. Lets at least let it compile for those
interested in getting it fixed.

Use correct NET_RX_* returns for atalk_rcv()

In all rx'd SKB cases, atalk_rcv() either eventually jumps to or falls through
    to the label out:, which  returns numeric 0. Numeric 0 corresponds to
    NET_RX_SUCCESS, which is incorrect in failed SKB cases.

    This patch makes atalk_rcv() provide the correct returns by:

    o  explicitly returning NET_RX_SUCCESS in the two success cases
    o  having the out: label return NET_RX_DROP, instead of numeric 0
    o  making the failed SKB labels and processing more consistent with other
       _rcv() routines in the kernel, simplifying validation and removing a
       backwards goto

f_phonet: use page-sized rather than MTU-sized RX buffers

Instead of a large (physically) linear buffer, we generate a set of
paged sk_buff, so no extra memory copy is involved. This removes
high-order allocations and saves quite a bit of memory. Phonet MTU is
65541 bytes, so the two buffers were padded to 128 kilo-bytes each.
Now, we create 17 page buffers, almost a 75% memory use reduction.

tun: Extend RTNL lock coverage over whole ioctl

As it is, parts of the ioctl runs under the RTNL and parts of
it do not.  The unlocked section is still protected by the BKL,
but there can be subtle races.  For example, Eric Biederman and
Paul Moore observed that if two threads tried to create two tun
devices on the same file descriptor, then unexpected results
may occur.

As there isn't anything in the ioctl that is expected to sleep
indefinitely, we can prevent this from occurring by extending
the RTNL lock coverage.

This also allows to get rid of the BKL.

Finally, I changed tun_get_iff to take a tun device in order to
avoid calling tun_put which would dead-lock as it also tries to
take the RTNL lock.

fec: fix FEC driver packet transmission breakage

Commit f0b3fbeae11a526c3d308b691684589ee37c359b ("FEC Buffer rework")
breaks transmission of packets where the skb data buffer is not memory
aligned according to FEC_ALIGNMENT. It incorrectly passes to
dma_sync_single() the buffer address directly from the skb, instead of
the address calculated for use (which may be the skb address or one of
the bounce buffers).

It seems there is no use converting the cpu address of the buffer to
a physical either, since dma_map_single() expects the cpu address and
will return the dma address to use in the descriptor. So remove the use
of __pa() on the buffer address as well.

This patch is against 2.6.30-rc5. This breakage is a regression over
2.6.30, which does not have this problem.
