** 8.replace pci_alloc_consistent()/pci_free_consistent() with kmalloc()/kfree() in arcmsr_iop_message_xfer()
** 9. fix the release of dma memory for type B in arcmsr_free_ccb_pool()
** 10.fix the arcmsr_polling_hbb_ccbdone()
** 1.20.00.15 02/27/2008 Erich Chen & Nick Cheng
** 1.arcmsr_iop_message_xfer() is called from atomic context under the
** queuecommand scsi_host_template handler. James Bottomley pointed out
** that the current GFP_KERNEL|GFP_DMA flags are wrong: firstly we are in
** atomic context, secondly this memory is not used for DMA.
** Also removed some unneeded casts. Thanks to Daniel Drake <dsd@gentoo.org>
