If FEATURE_CLEAN_UP is defined, then delete_eth_table() frees the previously allocated memory for the pointer 'ch'.

[d7e9711] "Double lock when debugging diskquota [e1fbd92] Argument type incompatible with `printk' format string AMIGA's ramdisk support contains a type error (reported as a warning by gcc) when LBDAF is enabled. The result of `blk_rq_pos(req)' has type `sector_t' and is printed as an unsigned long value. Yet, when LBDAF is enabled, type `sector_t' is defined as unsigned long long. There is no safe cast from unsigned long long to unsigned long. The fix consists in printing the value as unsigned long long instead, without losing precision when LBDAF is enabled.
