Update megaraid_sas to version 07.708.03.00. The initial patch contains a cleanup of unused variable. Next four patches contain driver fixes and enhancements. Patch 6 introduces IRQ polling in megaraid_sas driver to fix CPU hard/soft lockups that we have seen in the field. Patch 7 adds load balancing of IO completions across the available reply queues when combined MSIx mode is disabled in firmware. Patch 8 onwards adds few enhancements to improve debuggability of the driver by printing additional information and provding a debugfs interface to help debug field issues better.
