| H A D | cache.c | 76382b5b Thu Dec 24 00:12:02 CST 2009 Markus Pietrek <Markus.Pietrek@emtrion.de> sh: Ensure all PG_dcache_dirty pages are written back.
With some of the cache rework an address aliasing optimization was added,
but this managed to fail on certain mappings resulting in pages with
PG_dcache_dirty set never writing back their dcache lines. This patch
reverts to the earlier behaviour of simply always writing back when the
dirty bit is set.
