[PATCH] I2O: new sysfs attributes and Adaptec specific block device access and 64-bit DMA support
Changes: - Added Bus-OSM which could be used by user space programs to reset a channel on the controller - Make ioctl's in Config-OSM obsolete in prefer for sysfs attributes and move those to its own file - Added sysfs attribute for firmware read and write access for I2O controllers - Added special handling of firmware read and write access for Adaptec controllers - Added vendor id and product id as sysfs-attribute to Executive classes - Added automatic notification of LCT change handling to Exec-OSM - Added flushing function to Block-OSM for later barrier implementation - Use PRIVATE messages for Block access on Adaptec controllers, which are faster then BLOCK class access - Cleaned up support for Promise controller - New messages are now detected using the IRQ status register as suggested by the I2O spec - Added i2o_dma_high() and i2o_dma_low() functions - Added facility for SG tablesize calculation when using 32-bit and 64-bit DMA addresses - Added i2o_dma_map_single() and i2o_dma_map_sg() which could build the SG list for 32-bit as well as 64-bit DMA addresses 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>
