wext: fix alignment problem in serializing 'struct iw_point'
This fixes a typo in the definition of the serialized length of struct iw_point:
a) wireless.h is exported to userspace, the typo causes IW_EV_POINT_PK_LEN
to be 12 on 64-bit, and 8 on 32-bit systems (causing misalignment);
b) in compat-64 mode iwe_stream_add_point() memcpys overlap (see below).
The second case in in compat-64 mode looks like (variable names are as in
include/net/iw_handler.h:iwe_stream_add_point()):
This case could cause overrun whenever iw_point.length < 4.
The other two cases are -
* 32-bit systems: IW_EV_POINT_PK_LEN - IW_EV_LCP_PK_LEN = 8 - 4 = 4,
the second memcpy copies exactly the 4 required bytes;
* 64-bit systems: IW_EV_POINT_PK_LEN - IW_EV_LCP_PK_LEN = 12 - 4 = 8,
the second memcpy copies a superfluous (but non overlapping) 4 bytes.
The patch changes IW_EV_POINT_PK_LEN to be 8, so that in all 3 cases always only
the requested iw_point.{length,flags} (both __u16) are copied, avoiding overrrun
(compat-64) and superfluous copy (64-bit). In addition, the userspace header is
sanitized (in agreement with version 30 of the wireless tools).

However, these sockets still have SOCK_SEQPACKET read semantics when
bt_sock_recvmsg() is used to pull data from the receive queue. If the
application is only reading part of a frame, then the unread portion
of the frame is discarded. If the application requests more bytes
than are in the current frame, only the current frame's data is

make the code more generic for use with non-RFCOMM data over L2CAP.

This fixes a problem and a potential loophole with regard to seqno/ackno
validity: currently the initial adjustments to AWL/SWL are only performed
once at the begin of the connection, during the handshake.
Since the Sequence Window feature is always greater than Wmin=32 (7.5.2),
it is however necessary to perform these adjustments at least for the first
W/W' (variables as per 7.5.1) packets in the lifetime of a connection.
This requirement is complicated by the fact that W/W' can change at any time
during the lifetime of a connection.
Therefore it is better to perform that safety check each time SWL/AWL are
updated, as implemented by the patch.
A second problem solved by this patch is that the remote/local Sequence Window
feature values (which set the bounds for AWL/SWL/SWH) are undefined until the
feature negotiation has completed.
During the initial handshake we have more stringent sequence number protection;
the changes added by this patch effect that {A,S}W{L,H} are within the correct
bounds at the instant that feature negotiation completes (since the SeqWin
feature activation handlers call dccp_update_gsr/gss()).

To prevent unnecessary error message. pci_save_state() is also moved to
the end of ->probe() so that all PCI config, including AER state, will be
saved.
Update version to 2.0.18.

net dst: use a percpu_counter to track entries
struct dst_ops tracks number of allocated dst in an atomic_t field,
subject to high cache line contention in stress workload.
Switch to a percpu_counter, to reduce number of time we need to dirty a
central location. Place it on a separate cache line to avoid dirtying
read only fields.

net: clear heap allocations for privileged ethtool actions
Several other ethtool functions leave heap uncleared (potentially) by
drivers. Some interfaces appear safe (eeprom, etc), in that the sizes
are well controlled. In some situations (e.g. unchecked error conditions),
the heap will remain unchanged in areas before copying back to userspace.
Note that these are less of an issue since these all require CAP_NET_ADMIN.

rt2x00: Fix URB error handling
kill_urb guarentees that when the function returns, the URB has
been fully killed. This means we don't need the extra sleeping
after the call to kill_urb.
kill_urb can however also guarentee the submit_urb to fail, as
a result, we must catch the return value from submit_urb an
correctly mark the entry as owned by the driver, and the
status as broken.

All access to the queue_entry->flags can be done concurrently,

When the RX skb allocation failed, we should recycle
