From eca351336acb2fa943611e0846562ce3997ef53b Mon Sep 17 00:00:00 2001 From: Ben Collins Date: Tue, 29 Nov 2005 11:45:26 -0800 Subject: [PATCH] [PATCH] Fix missing pfn variables caused by vm changes I image this showed up because of "unused var..." when the changes occured, because flush_cache_page() is a noop in most places. This showed up for me on parisc however, where flush_cache_page() is a real function.
