1. Remove CACHE_ALL_LOOP2 macro because it is identical to CACHE_ALL_LOOP 2. Change BUG_ON to WARN_ON 3. Remove end aligned from CACHE_LOOP_LIMITS. C implementation do not need aligned end address and ASM code do aligned in their macros 4. ASM optimized CACHE_RANGE_LOOP_1/2 macros needs to get aligned end address. Because end address is compound from start + size, end address is the first address which is exclude. Here is the corresponding code which describe it. + int align = ~(line_length - 1); + end = ((end & align) == end) ? end - line_length : end & align; a) end is aligned: it is necessary to subtruct line length because we don't want to work with next cacheline b) end address is not aligned: Just align it to be ready for ASM code.
