[PATCH] sym53c8xx driver 2.1.18

[PATCH] sym53c8xx driver 2.1.18

Yes, there's a lot of changes here.  I've been busy :-P

 - Delete linux/version.h include as it's not necessary
 - Delete compatibility with ncr53c8xx configuration options
 - Convert to C99 initialisers
 - Delete the options: pci_parity, scsi_parity, min_sync, max_wide,
   max_offs, max_lun and pci_fix_up.  Some were unused, some are now
   unused.
 - Delete all the default settings from sym_conf.h that were unused.
 - Delete host_lock abstractions.
 - Replace custom jiffy handling with standard ones.
 - Replace u_long with unsigned long
 - Inline scsi_data_direction()
 - Use ioremap directly instead of indirecting through pci_map_mem.
 - Delete typedefs: bus_addr_t, ucmd_p, vm_offset_t, stcb_p,
   slcb_p, sccb_p, shcb_p, sym_device and sym_slot.
 - Use min() instead of MIN()
 - Use memcpy() instead of bcopy().
 - Delete code dependent on SYM_CONF_PCIQ_BROKEN_INTR as it's never defined.
 - Simplify the locking in sym_eh_handler().
 - Make the eh handlers static.
 - Use ctype.h instead of custom variants.
 - Use SYM_CONF_IOMAPPED and SYM_OPT_NO_BUS_MEMORY_MAPPING in a more
   consistent manner.
 - Remove check_region() and use pci_request_region instead.
 - Mark sym_detach() as __devexit.
 - Move many includes from sym_glue.h to sym_glue.c
 - Stop using Scsi_Cmnd.
 - Stop using ../hosts.h.
 - Simplify *_raw definitions.
 - Move PA-RISC specific code into its own function.
