From fa5c4639419668cbb18ca3d20c1253559a3b43ae Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Wed, 16 Apr 2008 02:29:42 +0200 Subject: [PATCH] x86: rename find_max_pfn() to propagate_e820_map() this function doesnt just 'find' the max_pfn - it also has other side-effects such as registering sparse memory maps.
