This patch fixes 2 SMP deadlocks.  The first is that mv64x60_read() was
returning before the unlock.  The second was mv64x60_modify() locks the
spin lock and calls mv64x60_read() and mv64x60_write() which also lock the
same spin lock.

include/asm-ppc/rwsem.h has '#ifdef RWSEM_DEBUG' but RWSEM_DEBUG is always

Fix some bugs in device-mapper handling of 64-bit values, replacing
dm_div_up() and dm_round_up() inlines with macros and removing some
avoidable divisions of 64-bit numbers.

The mirror region size is the granularity used to manage and monitor the
data copying, typically 512KB, so 32 bits (of sectors) should be plenty to
hold this.

Taken together with the two earlier patches:
  "fix TB stripe data corruption" (a missing cast) and
  "stripe_width should be sector_t",
I've now had 3 independent reports that this fixes device-mapper
for devices with large stripes.

Still awaiting test results for dm-crypt and dm-raid1.

Not that low-level code really tends to care, but since loff_t is
a signed 64-bit entity and size_t is unsigned (and potentially
64-bit), mixing the two isn't very well-defined.. 

The actual user copy will do them too, but only for the
range that ends up being actually copied. That hides
bugs when the range has been clamped by file size or other
issues.
