From 31c9efde786252112cc3d04a1ed3513b6ec63a7b Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Wed, 9 Sep 2009 14:10:28 +0900 Subject: [PATCH] sh: Kill off broken PHYSADDR() usage in sh4_flush_dcache_page(). PHYSADDR() runs in to issues in 32-bit mode when we do not have the legacy P1/P2 areas mapped, as such, we need to use page_to_phys() directly, which also happens to do the right thing in legacy 29-bit mode.
