-------
2.26.02.000 - Driver cleanup for kernel submission.
2.26.02.001 - Replace schedule_timeout() calls with msleep().
+ 2.26.02.002 - Add support for PAE mode.
+ Add lun support.
+ Fix twa_remove() to free irq handler/unregister_chrdev()
+ before shutting down card.
+ Change to new 'change_queue_depth' api.
+ Fix 'handled=1' ISR usage, remove bogus IRQ check.
+ Remove un-needed eh_abort handler.
+ Add support for embedded firmware error strings.
+ 2.26.02.003 - Correctly handle single sgl's with use_sg=1.
+ 2.26.02.004 - Add support for 9550SX controllers.
+ 2.26.02.005 - Fix use_sg == 0 mapping on systems with 4GB or higher.
+ 2.26.02.006 - Fix 9550SX pchip reset timeout.
+ Add big endian support.
+ 2.26.02.007 - Disable local interrupts during kmap/unmap_atomic().
+ 2.26.02.008 - Free irq handler in __twa_shutdown().
+ Serialize reset code.
+ Add support for 9650SE controllers.
