While I downloaded new firmware to eHBA-9600 on KASAN enabled kernel, I observed
three BUGs. During patch review for the BUG fixes, two more related issues were
found. The first two patches address the two issues found during review, and the
last three patches address the three BUGs respectively.

Changes from v2:
* Added 1st and 2nd patches to address issues found during review
* 3rd patch: changed fix approach per comment on the list
* Added Acked-by and Reviewed-by tags

Changes from v1:
* 2nd patch: Modified to use bitmap helper functions and number of bits
* 1st/3rd patches: Reflected a comment on the list and added Reviewed-by tags
