Flush_icache_range takes two arguments, start and end address. Both
addresses are the virtual addresses at which the code will run. Iow both
arguments are wrong. The result is that for start address values normally
passed to flush_icache_range it will optimize the flush into a full cache
flush of I-cache and D-cache - iow you're lucky.
