This patch cleans up asm-ppc64/byteorder.h to enable ___arch__swab16 and
___arch__swab32 which are marked TODO currently. It removes ___arch__swab64
because ppc64 does not have short instruction combinations for swab64, the
recent gcc generates enough smart code that is equivalent to hand assembled
code under my tests.

In the case of buffered AIO, in the aio retry path (aio_run_iocb), when the
retry method returns EIOCBRETRY the kicked iocb is added to the context run
list but is never queued onto the work queue. The request therefore is
never completed.
This patch fixes that by adding the appropriate call to aio_queue_work in
aio_run_aiocb so that subsequent retries will be handled by the aio worker
thread.

As Steven Rostedt pointed out, there are 2 problems with ITIMER_REAL
timers.
1. do_setitimer() does not call del_timer_sync() in case
when the timer is not pending (it_real_value() returns 0).
This is wrong, the timer may still be running, and it can
rearm itself.
2. It calls del_timer_sync() with tsk->sighand->siglock held.
This is deadlockable, because timer's handler needs this
lock too.

In 2.6.12 we started dropping the conntrack reference when a packet
leaves the IP layer. This broke connection tracking on a bridge,
because bridge-netfilter defers calling some NF_IP_* hooks to the bridge
layer for locally generated packets going out a bridge, where the
conntrack reference is no longer available. This patch keeps the
reference in this case as a temporary solution, long term we will
remove the defered hook calling. No attempt is made to drop the
reference in the bridge-code when it is no longer needed, tc actions
could already have sent the packet anywhere.

In an smp system, it is possible for an connection timer to expire, calling
ip_vs_conn_expire while the connection table is being flushed, before
ct_write_lock_bh is acquired.
Since the list iterator loop in ip_vs_con_flush releases and re-acquires the
spinlock (even though it doesn't re-enable softirqs), it is possible for the
expiration function to modify the connection list, while it is being traversed
in ip_vs_conn_flush.
The result is that the next pointer gets set to NULL, and subsequently
dereferenced, resulting in an oops.

Many drivers use skb->tail unnecessarily.
In these situations, the code roughly looks like:
dev = dev_alloc_skb(...);
[optional] skb_reserve(skb, ...);
... skb->tail ...
But even if the skb_reserve() happens, skb->data equals
skb->tail. So it doesn't make any sense to use anything
other than skb->data in these cases.
Another case was the s2io.c driver directly mucking with
the skb->data and skb->tail pointers. It really just wanted
to do an skb_reserve(), so that's what the code was changed
to do instead.
Another reason I'm making this change as it allows some SKB
cleanups I have planned simpler to merge. In those cleanups,
skb->head, skb->tail, and skb->end pointers are removed, and
replaced with skb->head_room and skb->tail_room integers.

This patch tweaks idle thread setup semantics a bit: instead of setting
NEED_RESCHED in init_idle(), we do an explicit schedule() before calling
into cpu_idle().
This patch, while having no negative side-effects, enables wider use of
cond_resched()s. (which might happen in the stock kernel too, but it's
particulary important for voluntary-preempt)

Currently we cap request allocations at q->nr_requests, but we allow a
batching io context to allocate up to 32 more (default setting). This
can flood the queue with request allocations, with only a few batching
processes. The real fix would be to limit the number of batchers, but
as that isn't currently tracked, I suggest we just cap the maximum
number of allocated requests to eg 50% over the limit.
This was observed in real life, users typically see this as vmstat bo
numbers going off the wall with seconds of no queueing afterwards.
Behaviour this bursty is not beneficial.

I think there is a small bug in ipconfig.c in case IPCONFIG_DHCP is set
and dhcp is used.
When a DHCPOFFER is received, ip address is kept until we get DHCPACK.
If no ack is received, ic_dynamic() returns negatively, but leaves the
offered ip address in ic_myaddr.
This makes the main loop in ip_auto_config() break and uses the maybe
incomplete configuration.
Not sure if it's the best way to do, but the following trivial patch
correct this.

I followed Thomas' proposal to see every martian destination as a case
where the ipInAddrErrors counter has to be incremented. There are
two advantages by doing so: (1) The relation between the ipInReceive
counter and all the other ipInXXX counters is more accurate in the
case the RTN_UNICAST code check fails and (2) it makes the code in
ip_route_input_slow easier.

This patch was suggested by RMK, and adds a warning on the accuracy
of timekeeping when using dynamic tick on some platforms. Depending
on the timer implementation, dynamic tick may affect the accuracy of
timekeeping.
Currently at least OMAP is known to have accurate timekeeping with
dynamic tick.
