[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 Signed-off-by: Markus Lidel <Markus.Lidel@shadowconnect.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
