Cheng113** 1.arcmsr_iop_message_xfer() is called from atomic context under the114** queuecommand scsi_host_template handler. James Bottomley pointed out115** that the current GFP_KERNEL|GFP_DMA flags are wrong: firstly we are in116** atomic context, secondly this memory is not used for DMA.117** Also removed some unneeded casts.
