Thanks for the reminder about the legal issues, I totally forgot about
reaching out to the authors.
The patches do work for me, but only if you're lucky enough to be on a
platform where it's fine to allocate a gigabyte of RAM (which is the
default memory-hardness for Argon2i). Unfortunately EFI isn't one of
them, which is why I've been working towards improving the memory
management subsystem to cope with such huge requests. So be warned if
you're trying out those patches, as decryption will quite likely fail
with an out-of-memory warning.
