Changes:

 - Fixed sysfs bug where user and parent links where added to the I2O
   device itself
 - Fixed bug when calculating TID for the event handler and cleaned up the
   workflow of i2o_driver_dispatch()
 - Fixed oops when no I2O device could be found for an event delivered to
   Exec-OSM
 - Fixed initialization of spinlock in Exec-OSM
 - Fixed memory leak in i2o_cfg_passthru() and i2o_cfg_passthru()
 - Removed MTRR support
 - Added PCI ID of Promise SX6000 with firmware >= 1.20.x.x
 - Turn of caching for ioremapped memory of in_queue
 - Added initialization sequence for Promise controllers
 - Moved definition of u8 / u16 / u32 for raidutils before first use
