Subject: [PATCH] x86_64: reserve crashkernel bootmem before reserve dma32 bootmem
Date: Mon, 14 Jul 2008 10:16:40 -0700 [thread overview]
Message-ID: <200807141016.40572.yhlu.kernel@gmail.com> (raw)
From: Joe Jin <joe.jin@oracle.com>
Before reserve_crashkernel, dma32_reserve_bootmem would reserve 128M memory.
this cuased crashkernel end address must less than 64M or start address must
more than 192M except crashkernel memory reserved before dma32 memory reserved.
