[NET]: Update frag_list in pskb_trim
When pskb_trim has to defer to ___pksb_trim to trim the frag_list part of
the packet, the frag_list is not updated to reflect the trimming. This
will usually work fine until you hit something that uses the packet length
or tail from the frag_list.
Examples include esp_output and ip_fragment.
Another problem caused by this is that you can end up with a linear packet
with a frag_list attached.
It is possible to get away with this if we audit everything to make sure
that they always consult skb->len before going down onto frag_list. In
fact we can do the samething for the paged part as well to avoid copying
the data area of the skb. For now though, let's do the conservative fix
and update frag_list.

knfsd: Fix race that can disable NFS server.
This is a long standing bug that seems to have only recently become
apparent, presumably due to increasing use of NFS over TCP - many
distros seem to be making it the default.
The SK_CONN bit gets set when a listening socket may be ready
for an accept, just as SK_DATA is set when data may be available.
It is entirely possible for svc_tcp_accept to be called with neither
of these set. It doesn't happen often but there is a small race in
svc_sock_enqueue as SK_CONN and SK_DATA are tested outside the
spin_lock. They could be cleared immediately after the test and
before the lock is gained.
This normally shouldn't be a problem. The sockets are non-blocking so
trying to read() or accept() when ther is nothing to do is not a problem.
However: svc_tcp_recvfrom makes the decision "Should I accept() or
should I read()" based on whether SK_CONN is set or not. This usually
works but is not safe. The decision should be based on whether it is
a TCP_LISTEN socket or a TCP_CONNECTED socket.

posix-cpu-timers: prevent signal delivery starvation
The integer divisions in the timer accounting code can round the result
down to 0. Adding 0 is without effect and the signal delivery stops.
Clamp the division result to minimum 1 to avoid this.
Problem was reported by Seongbae Park <spark@google.com>, who provided
also an inital patch.
Roland sayeth:
I have had some more time to think about the problem, and to reproduce it
using Toyo's test case. For the record, if my understanding of the problem
is correct, this happens only in one very particular case. First, the
expiry time has to be so soon that in cputime_t units (usually 1s/HZ ticks)
it's < nthreads so the division yields zero. Second, it only affects each
thread that is so new that its CPU time accumulation is zero so now+0 is
still zero and ->it_*_expires winds up staying zero. For the VIRT and PROF
clocks when cputime_t is tick granularity (or the SCHED clock on
configurations where sched_clock's value only advances on clock ticks), this
is not hard to arrange with new threads starting up and blocking before they
accumulate a whole tick of CPU time. That's what happens in Toyo's test
case.
Note that in general it is fine for that division to round down to zero,
and set each thread's expiry time to its "now" time. The problem only
arises with thread's whose "now" value is still zero, so that now+0 winds up
0 and is interpreted as "not set" instead of ">= now". So it would be a
sufficient and more precise fix to just use max(ticks, 1) inside the loop
when setting each it_*_expires value.
But, it does no harm to round the division up to one and always advance
every thread's expiry time. If the thread didn't already fire timers for
the expiry time of "now", there is no expectation that it will do so before
the next tick anyway. So I followed Thomas's patch in lifting the max out
of the loops.
This patch also covers the reload cases, which are harder to write a test
for (and I didn't try). I've tested it with Toyo's case and it fixes that.

will spawn. This patch will prevent confusion by warning the user that
only one of the chips on the board are functional.
There are other versions of the SAA7134_BOARD_MD7134 with only a single
saa7134 bridge/decoder -- those devices will not be affected by this patch.
Only devices containing the second chip will display the warning.

V4L/DVB: Saa7134: make unsupported secondary decoder message generic
There are already some supported devices that contain two
saa713x chips on-board, where only one of these chips is
currently functional in the driver.
We are already printing a warning message for the second
saa7134 decoder in SAA7134_BOARD_AVERMEDIA_A169_B. This
patch alters that case to make it generic, so that other
cards in the same situation can use it.

V4L/DVB: Saa7134: add support for AVerMedia A169 Dual Analog tuner card
- Added support for AVerMedia A169 Dual Analog tuner card
(dual saa7134 decoders - only 1 working right now)
- Added autodetection for both parts of the card.
It shows up like 2 cards, B1 and B
- Enabled tuner B1, SVIDEO on B1 and composite1 through SVIDEO,
FIXME: B is more or less dead at this point and I suspect the
FM-radio is on the B part of the board
Adrian Bunk:
slightly adapted to 2.6.16

V4L/DVB: Kworld ATSC110: initialize the tuner for analog mode on module load
- Enable the tuv1236 tuner on the Kworld-ATSC110 card so that the
tuner can be identified when tuners.ko loads.
- With this change it is no longer necessary to remove and reload
the tuner module in order to get the tuv1236 identified.
- This code was copied from the ATI HDTV Wonder init routine (in cx88-cards.c)
which also uses the TUV1236D.
