- * ===================
- *
- * The arch/arm/mm/cache-*.S and arch/arm/mm/proc-*.S files
- * implement these methods.
- *
- * Start addresses are inclusive and end addresses are exclusive;
- * start addresses should be rounded down, end addresses up.
- *
- * See Documentation/cachetlb.txt for more information.
- * Please note that the implementation of these, and the required
- * effects are cache-type (VIVT/VIPT/PIPT) specific.
- *
- * flush_icache_all()
- *
- * Unconditionally clean and invalidate the entire icache.
- * Currently only needed for cache-v6.S and cache-v7.S, see
- * __flush_icache_all for the generic implementation.
- *
- * flush_kern_all()
- *
- * Unconditionally clean and invalidate the entire cache.
- *
- * flush_kern_louis()
- *
- * Flush data cache levels up to the level of unification
- * inner shareable and invalidate the I-cache.
- * Only needed from v7 onwards, falls back to flush_cache_all()
- * for all other processor versions.
- *
- * flush_user_all()
- *
- * Clean and invalidate all user space cache entries
- * before a change of page tables.
- *
- * flush_user_range(start, end, flags)
- *
- * Clean and invalidate a range of cache entries in the
