This is the next page of the scm recursion story (the commit 
f8d570a4 net: Fix recursive descent in __scm_destroy()).

In function scm_fp_dup(), the INIT_LIST_HEAD(&fpl->list) of newly
created fpl is done *before* the subsequent memcpy from the old 
structure and thus the freshly initialized list is overwritten.

But that's OK, since this initialization is not required at all,
since the fpl->list is list_add-ed at the destruction time in any
case (and is unused in other code), so I propose to drop both
initializations, rather than moving it after the memcpy.

Please, correct me if I miss something significant.

This patch fixes two bugs:

1. setsockopt() of anything but a Type 2 routing header should return
EINVAL instead of EPERM.  Noticed by Shan Wei
(shanwei@cn.fujitsu.com).

2. setsockopt()/sendmsg() of a Type 2 routing header with invalid
length or segments should return EINVAL.  These values are statically
fixed in RFC 3775, unlike the variable Type 0 was.

This fixes a TX hang reported by Jesper Dangaard Brouer.

When an architecutre cannot provide a fully functional
64-bit atomic readq/writeq, the driver must implement
it's own.  This is because only the driver can say whether
doing something like using two 32-bit reads to implement
the full 64-bit read will actually work properly.

In particular one of the issues is whether the top 32-bits
or the bottom 32-bits of the 64-bit register should be read
first.  There could be side effects, and in fact that is
exactly the problem here.

The TX_CS register has counters in the upper 32-bits and
state bits in the lower 32-bits.  A read clears the state
bits.

We would read the counter half before the state bit half.
That first read would clear the state bits, and then the
driver thinks that no interrupts are pending because the
interrupt indication state bits are seen clear every time.

Fix this by reading the bottom half before the upper half.

Like mac80211 did, this driver makes 'clever' use of skb->cb to pass
information along with an skb as it is requeued from the virtual device
to the physical wireless device.  Unfortunately, that trick no longer
works...

Unlike mac80211, code complexity and driver apathy makes this hack
the best option we have in the short run.  Hopefully someone will
eventually be motivated to code a proper fix before all the effected
hardware dies.

This patch fixes a minor bug in tcp_htcp.c which has been
highlighted by Lachlan Andrew and Lawrence Stewart.  Currently, the
time since the last congestion event, which is stored in variable
last_cong, is reset whenever there is a state change into
TCP_CA_Open.  This includes transitions of the type
TCP_CA_Open->TCP_CA_Disorder->TCP_CA_Open which are not associated
with backoff of cwnd.  The patch changes last_cong to be updated
only on transitions into TCP_CA_Open that occur after experiencing
the congestion-related states TCP_CA_Loss, TCP_CA_Recovery,
TCP_CA_CWR.
