From 6abf65510944d33b47575d151c6b318993c8d2b5 Mon Sep 17 00:00:00 2001 From: Jan Beulich Date: Thu, 30 Jul 2009 16:49:30 +0100 Subject: [PATCH] x86, 32-bit: Fix double accounting in reserve_top_address() With VMALLOC_END included in the calculation of MAXMEM (as of 2.6.28) it is no longer correct to also bump __VMALLOC_RESERVE in reserve_top_address(). Doing so results in needlessly small lowmem.
