Can you be a bit more specific in your commit messages ? That applies to 
the entire patchset. It is absolutely impossible to tell what race is 
fixed here or why it is fixed by exactly this change. This applies to 
the entire series.

And while I am at it, does the CRYP finally pass at least the most basic 
kernel boot time crypto tests or does running those still overwrite 
kernel memory and/or completely crash or lock up the machine ?
