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.
