Subject: [PATCH] x86_64: reserve crashkernel bootmem before reserve dma32 bootmem
Date: Thu, 10 Jul 2008 20:34:46 +0800 [thread overview]
Message-ID: <20080710123446.GA1595@joejin-pc.cn.oracle.com> (raw)
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.
