[PATCH] 3ware driver update for 2.5.6-pre3 

 - Fix bug in tw_aen_complete() where aen's could be lost.
   Fix tw_aen_drain_queue() to display useful info at init.
   Set tw_host->max_id for 12 port cards.
   Add ioctl support for raw command packet post from userspace
   with sglist fragments (parameter and io).
 - Fix read capacity to under report by 1 sector to fix get
   last sector ioctl.
 - Fix bug where more AEN codes weren't coming out during
   driver initialization.
   Improved handling of PCI aborts.
 - Fix bug in tw_findcards() where AEN code could be lost.
   Increase timeout in tw_aen_drain_queue() to 30 seconds.
 - Re-write raw command post with data ioctl method.
   Remove raid5 bounce buffers for raid5 for 6XXX for kernel 2.5
   Add tw_map/unmap_scsi_sg/single_data() for kernel 2.5
   Replace io_request_lock with host_lock for kernel 2.5
   Set max_cmd_len to 16 for 3dm for kernel 2.5
 - Set host->max_sectors back up to 256.
 - Modified pci parity error handling/clearing from config space
   during initialization.
 - Better handling of request sense opcode and sense information
   for failed commands.  Add tw_decode_sense().
   Replace all mdelay()'s with scsi_sleep().
 - Revert mdelay's and scsi_sleep's, this caused problems on
   some SMP systems.
 - Add pci_set_dma_mask(), rewrite kmalloc()/virt_to_bus() to
   pci_alloc/free_consistent().
