isdn_if.writebuf_skb has an additional ack flag argument which
was missing from sndpkt leading to the following warning:
CC [M] drivers/isdn/sc/init.o
drivers/isdn/sc/init.c: In function ‘sc_init’:
drivers/isdn/sc/init.c:281: warning: assignment from incompatible pointer type
Note that this doesn't actually do anything with the flag, it
just fixes the warning (and probably accessing the last argument).

I broke this in commit 3de96471bd7fb76406e975ef6387abe3a0698149:
[TCP]: Wrap-safed reordering detection FRTO check
tcp_process_frto should always see a valid frto_highmark. An invalid
frto_highmark (zero) is very likely what ultimately caused a seqno
compare in tcp_frto_enter_loss to do the wrong leading to the LOST-bit
leak.
Having LOST-bits integry ensured like done after commit
23aeeec365dcf8bc87fae44c533e50d0bb4f23cc:
[TCP] FRTO: Plug potential LOST-bit leak
won't hurt. It may still be useful in some other, possibly legimate,
scenario.

Commit fcc5a03ac42564e9e255c1134dda47442289e466:
[NET]: Allow netdev REGISTER/CHANGENAME events to fail
makes the register_netdevice_notifier() handle the error from the
NETDEV_REGISTER event, sent to the registering block.
The bad news is that in this case the notifier block is
not removed from the list, but the error is returned to the
caller. In case the caller is in module init function and
handles this error this can abort the module loading. The
notifier block will be then removed from the kernel, but
will be left in the list. Oops :(
I think that the notifier block should be removed from the
chain in case of error, regardless whether this error is
handled by the caller or not. In the worst case (the error
is _not_ handled) module will not receive the events any
longer.

If fs_enet is build as module, on PPC_CPM_NEW_BINDING platforms
mii-fec/mii-bitbang should be build as module, as well. On other
platforms, mii-fec/mii-bitbang must be included into the main module.
Otherwise some symbols remain undefined. Additionally, fs_enet uses
libphy, so add a select PHYLIB.

NULL ptr can be returned from tcp_write_queue_head to cached_skb
and then assigned to skb if packets_out was zero. Without this,
system is vulnerable to a carefully crafted ACKs which obviously
is remotely triggerable.
Besides, there's very little that needs to be done in sacktag
if there weren't any packets outstanding, just skipping the rest
doesn't hurt.

We round up the header size in sk_stream_alloc_pskb so that
TSO packets get zero tail room. Unfortunately this rounding
up is not coordinated with the select_size() function used by
TCP to calculate the second parameter of sk_stream_alloc_pskb.
As a result, we may allocate more than a page of data in the
non-TSO case when exactly one page is desired.
In fact, rounding up the head room is detrimental in the non-TSO
case because it makes memory that would otherwise be available to
the payload head room. TSO doesn't need this either, all it wants
is the guarantee that there is no tail room.
So this patch fixes this by adjusting the skb_reserve call so that
exactly the requested amount (which all callers have calculated in
a precise way) is made available as tail room.

Fix thinko in commit eaf559bf ("mlx4_core: Don't free special QPs in
QP number bitmap"). The old commit had the logic exactly backwards
and ended up freeing *only* special QPs, which not only left the
original bug in place but also introduced the problem that the QP
number bitmap would get full after a while.

All 32 bits machines but i386 dont have CONFIG_KTIME_SCALAR. On these
machines, ktime.tv64 is more than 4 times the (correct) result given
by ktime_to_ns()
Again on these machines, using ktime_get_real().tv64 >> 6 give a
32bits rollover every 64 seconds, which is not wanted (less than the
120 s MSL)
Using ktime_to_ns() is the portable way to get nsecs from a ktime, and
have correct code.

Otherwise TCP might violate packet ordering principles that FRTO
is based on. If conventional recovery path is chosen, this won't
be significant at all. In practice, any small enough value will
be sufficient to provide proper operation for FRTO, yet other
users of snd_cwnd might benefit from a "close enough" value.
FRTO's formula is now equal to what tcp_enter_cwr() uses.
FRTO used to check application limitedness a bit differently but
I changed that in commit 575ee7140dabe9b9c4f66f4f867039b97e548867
and as a result checking for application limitedness became
completely non-existing.

The only qdiscs that check subqueue state before dequeue'ing are PRIO
and RR. The other qdiscs, including the default pfifo_fast qdisc,
will allow traffic bound for subqueue 0 through to hard_start_xmit.
The check for netif_queue_stopped() is done above in pkt_sched.h, so
it is unnecessary for qdisc_restart(). However, if the underlying
driver is multiqueue capable, and only sets queue states on subqueues,
this will allow packets to enter the driver when it's currently unable
to process packets, resulting in expensive requeues and driver
entries. This patch re-adds the check for the subqueue status before
calling hard_start_xmit, so we can try and avoid the driver entry when
the queues are stopped.

This reverts commit 7c9e69faa28027913ee059c285a5ea8382e24b5d, fixing up
conflicts in fs/ext4/balloc.c manually.
The cost of doing the bitmap validation on each lookup - even when the
bitmap is cached - is absolutely prohibitive. We could, and probably
should, do it only when adding the bitmap to the buffer cache. However,
right now we are better off just reverting it.
Peter Zijlstra measured the cost of this extra validation as a 85%
decrease in cached iozone, and while I had a patch that took it down to
just 17% by not being _quite_ so stupid in the validation, it was still
a big slowdown that could have been avoided by just doing it right.
