There is no good reason to keep genhd.h separate from the main blkdev.h
header that includes it.  So fold the contents of genhd.h into blkdev.h
and remove genhd.h entirely.

Drop various include not actually used in genhd.h itself, and
move the remaning includes closer together.

Use struct block_device to lookup partitions on a disk.  This removes
all usage of struct hd_struct from the I/O path.

<content type='text'>
Allocate hd_struct together with struct block_device to pre-load
the lifetime rule changes in preparation of merging the two structures.

Note that part0 was previously embedded into struct gendisk, but is
a separate allocation now, and already points to the block_device instead
of the hd_struct.  The lifetime of struct gendisk is still controlled by
the struct device embedded in the part0 hd_struct.

Most architectures have fast path to access percpu for current cpu.
The required preempt_disable() is provided by part_stat_lock().

The RCU lock is required only in disk_map_sector_rcu() to lookup the
partition.  After that request holds reference to related hd_struct.

Replace get_cpu() with preempt_disable() - returned cpu index is unused.

percpu variables have a perfectly fine working stub implementation
for UP kernels, so use that.

These macros are just used by a few files.  Move them out of genhd.h,
which is included everywhere into a new standalone header.
