9e87545f06
Changes: - Added header "core.h" for i2o_core.ko internal definitions - More sparse fixes - Changed display of TID's in sysfs attributes from XXX to 0xXXX - Use the right functions for accessing I/O and normal memory - Removed error handling of SCSI device errors and let the SCSI layer take care of it - Added new device / removed device handling to SCSI-OSM - Make status access volatile - Cleaned up activation of I2O controller - Removed unnecessary wmb() and rmb() calls - Use own struct i2o_io for I/O memory instead of struct i2o_dma 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>
