xip sendfile removal

xip without replacement. Those customers that use xip on s390 are not
using sendfile() as far as we know, and so far s390 is the only platform
this could potentially be used on so far.
Having sendfile is not a popular feature for execute in place file
systems, however we have a working implementation of splice_read() based
on fs/splice.c if anyone asks for it.
At this point in time, it does not seem preferable to merge
splice_read() for xip because it causes extra maintenence effort due to
code duplication and it requires struct page behind the xip memory
segment. We'd like to get rid of that in favor of supporting flash based

[BLOCK] drop unnecessary bvec rewinding from flush_dry_bio_endio

Barrier bios are completed twice - once after the barrier write itself
is done and again after the whole sequence is complete.
flush_dry_bio_endio() is for the first completion.  It doesn't really
complete the bio.  It rewinds bvec and resets bio so that it can be
completed again when the whole barrier sequence is complete.

The bvec rewinding code has the following problems.

1. The rewinding code is wrong because filesystems may pass bvec with
   non zero bv_offset.

2. The block layer doesn't guarantee anything about the state of
   bvec array on request completion.  bv_offset and len are updated
   iff __end_that_request_first() completes the bvec partially.

Because of #2, #1 doesn't really matter (nobody cares whether bvec is
re-wound correctly or not) but then again by not doing unwinding at
all, we'll always give back the same bvec to the caller as full bvec
completion doesn't alter bvecs and the final completion is always full
completion.

Drop unnecessary rewinding code.

Based on patch "the scheduled removal of RAW1394_REQ_ISO_{SEND,LISTEN}"
from Adrian Bunk, November 20 2006.

This patch also removes the underlying facilities in ohci1394 and
disables them in pcilynx.  That is, hpsb_host_driver.devctl() and
hpsb_host_driver.transmit_packet() are no longer used for iso reception
and transmission.

Since video1394 and dv1394 only work with ohci1394 and raw1394's rawiso
interface has never been implemented in pcilynx, pcilynx is now no
longer useful for isochronous applications.

raw1394 will still handle the request types but will complete the
requests with errors that indicate API version conflicts.
