From b1f006b65c12b85df81f12c1073ad18fd26f4a16 Mon Sep 17 00:00:00 2001 From: Yinghai Lu Date: Mon, 9 Jun 2008 18:11:36 -0700 Subject: [PATCH] x86: make generic arch support NUMAQ, fix #2 we are checking mptable early for numaq, so don't need to reserve_bootmem for it. bootmem is not there yet. do the same thing as 64-bit. found it on 64g above system from 64-bit kernel kexec to 32 bit kernel with numaq support.
