e4025f6c21 block: don't set REQ_NOMERGE unnecessarily 
RQ_NOMERGE_FLAGS already clears defines which REQ flags aren't
mergeable.  There is no reason to specify it superflously.  It only
adds to confusion.  Don't set REQ_NOMERGE for barriers and requests
with specific queueing directive.  REQ_NOMERGE is now exclusively used
by the merging code.

[ Impact: cleanup ]

710027a48e Add some block/ source files to the kernel-api docbook. Fix kernel-doc notation in them as needed. Fix changed function parameter names. Fix typos/spellos. In comments, change REQ_SPECIAL to REQ_TYPE_SPECIAL and REQ_BLOCK_PC to REQ_TYPE_BLOCK_PC.

681a561b7e block: unexport blk_end_sync_rq 
All the users of blk_end_sync_rq has gone (they are converted to use
blk_execute_rq). This unexports blk_end_sync_rq.

9a2d43b756 block: handle blk_pm_resume_request() requests in blk_execute_rq_nowait() 
For blk_pm_resume_request() requests (which are used only by IDE subsystem
currently) the queue is stopped so we need to call ->request_fn explicitly.

Thanks to:
- Rafael for reporting/bisecting the bug
- Borislav/Rafael for testing the fix

This is a preparation for converting IDE to use blk_execute_rq().
