From 751752789162fde69474edfa15935d0a77c0bc17 Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Wed, 30 Jan 2008 13:33:17 +0100 Subject: x86: replace hard coded reservations in 64-bit early boot code with dynamic table On x86-64 there are several memory allocations before bootmem. To avoid them stomping on each other they used to be all hard coded in bad_area(). Replace this with an array that is filled as needed. This cleans up the code considerably and allows to expand its use.
