Linux 2.6.36 compat, blk_* macros removed

Most of the blk_* macros were removed in 2.6.36.  Ostensibly this was
done to improve readability and allow easier grepping.  However, from
a portability stand point the macros are helpful.  Therefore the needed
macros are redefined here if they are missing from the kernel.
