From 0fc73099dd25df2c5181b7bad57d1faa5cd12d3c Mon Sep 17 00:00:00 2001 From: Catalin Marinas <catalin.marinas@arm.com> Date: Mon, 13 Sep 2010 15:57:05 +0100 Subject: [PATCH] ARM: 6378/1: Allow lazy cache flushing via PG_arch_1 for highmem pages Commit d73cd42 forced non-lazy cache flushing of highmem pages in flush_dcache_page(). This isn't needed since __flush_dcache_page() (called lazily from update_mmu_cache) can handle highmem pages (fixed by commit 7e5a69e).
