From 2e4e27c7d082b2198b63041310609d7191185a9d Mon Sep 17 00:00:00 2001 From: Adam Lackorzynski Date: Sun, 4 Jan 2009 12:00:46 -0800 Subject: [PATCH] vmalloc.c: fix flushing in vmap_page_range() The flush_cache_vmap in vmap_page_range() is called with the end of the range twice. The following patch fixes this for me.
