Hello!

The attached patch remove the get_hardblock_size() function entierly
from the kernel. This is due to the fact that this function is
compleatly
unneccessary due to the existance of get_hardsect_size(), which got
introduced to properly encapsulate acesses to the hardsec_size[].
As a side effect this is reducing the number of module call-entrypoints
by one, which is a Good Thing TM.

Plase just apply it...
