It works, thanks! Please could you also add pbkdf2 speed fix to 1.6.1?

Because cryptsetup supports several backends (where this flawed whirlpool
was never present), I won't do any automatic repairs but instead I added
internal "whirlpool_gcryptbug" hash name to gcrypt cryptsetup backend
(which uses this flag with gcrypt > 1.6.0)

This will allow people to use it if really needed.

Thanks,
Milan
