H A D | cache.c | f4281bba Mon Feb 29 20:37:58 CST 2016 Paul Burton <paul.burton@imgtec.com> MIPS: Handle highmem pages in __update_cache
The following patch will expose __update_cache to highmem pages. Handle them by mapping them in for the duration of the cache maintenance, just like in __flush_dcache_page. The code for that isn't shared because we need the page address in __update_cache so sharing became messy. Given that the entirity is an extra 5 lines, just duplicate it.
