* Add CONFIG_IDE_XFER_MODE config option to be selected by host drivers
that support xfer mode tuning.
* Add CONFIG_IDE_XFER_MODE=n static inline versions of ide_set_pio()
and ide_set_xfer_rate().
* Make IDE_TIMINGS and BLK_DEV_IDEDMA config options select IDE_XFER_MODE,
also add explicit selects for few host drivers that need it.

Impact: cleanup, new schedstat ABI
Since they are used on in statistics and are always set to zero, the
following fields from struct rq have been removed: yld_exp_empty,
yld_act_empty and yld_both_empty.
Both Sched Debug and SCHEDSTAT_VERSION versions has also been
incremented since ABIs have been changed.
The schedtop tool has been updated to properly handle new version of
schedstat:

We use RCU to defer freeing of conntrack structures. In DOS situation, RCU might
accumulate about 10.000 elements per CPU in its internal queues. To get accurate
conntrack counts (at the expense of slightly more RAM used), we might consider
conntrack counter not taking into account "about to be freed elements, waiting
in RCU queues". We thus decrement it in nf_conntrack_free(), not in the RCU
callback.

Honour barrier requests in the loop back block device driver.

Currently inherited from sg.c bsg will submit asynchronous request
at the head-of-the-queue, (using "at_head" set in the call to
blk_execute_rq_nowait()). This is bad in situation where the queues
are full, requests will execute out of order, and can cause
starvation of the first submitted requests.
The sg_io_v4->flags member is used and a bit is allocated to denote the
Q_AT_TAIL. Zero is to queue at_head as before, to be compatible with old
code at the write/read path. SG_IO code path behavior was changed so to
be the same as write/read behavior. SG_IO was very rarely used and breaking
compatibility with it is OK at this stage.
sg_io_hdr at sg.h also has a flags member and uses 3 bits from the first
nibble and one bit from the last nibble. Even though none of these bits
are supported by bsg, The second nibble is allocated for use by bsg. Just
in case.
