From 9e2779fa281cfda13ac060753d674bbcaa23367e Mon Sep 17 00:00:00 2001 From: Christoph Lameter Date: Mon, 4 Feb 2008 22:28:34 -0800 Subject: is_vmalloc_addr(): Check if an address is within the vmalloc boundaries Checking if an address is a vmalloc address is done in a couple of places. Define a common version in mm.h and replace the other checks. Again the include structures suck. The definition of VMALLOC_START and VMALLOC_END is not available in vmalloc.h since highmem.c cannot be included there.
