113 **                                              1.arcmsr_iop_message_xfer() is called from atomic context under the
114 **                                              queuecommand scsi_host_template handler. James Bottomley pointed out
115 **                                              that the current GFP_KERNEL|GFP_DMA flags are wrong: firstly we are in
116 **                                              atomic context, secondly this memory is not used for DMA.
117 **                                              Also removed some unneeded casts. Thanks to Daniel Drake <dsd@gentoo.org>
