From de62893bc0725f8b5f0445250577cd7a10b2d8f8 Mon Sep 17 00:00:00 2001 From: Atsushi Nemoto Date: Mon, 13 Mar 2006 18:23:03 +0900 Subject: [MIPS] local_r4k_flush_cache_page fix If dcache_size != icache_size or dcache_size != scache_size, or set-associative cache, icache/scache does not flushed properly. Make blast_?cache_page_indexed() masks its index value correctly. Also, use physical address for physically indexed pcache/scache.
