With this patch applied it still doesn't work as expected. The overflow
messages are gone however syslog shows
[  120.924266] hifn0: abort: c: 0, s: 1, d: 0, r: 0.
when doing cryptsetup luksFormat as in original e-mail. At this point
cryptsetup hangs and can't be killed with -SIGKILL. I've attached
SysRq-t dump of this condition.
