[PATCH] I2O: bugfixes and compability enhancements
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
