For those involved in the bcache support in storage-ng, this is Coly's answer to the question about the current status in all archs.

Bcache-tools can run on non-x86_64 platform, at least other people and I run them on s390x. The problem is, bcache code, everywhere, assume the machine is x86_64, even in formatting a bcache device, it does not handle bit order in meta data structures, and the checksum calculation order is wrong on big endian machines. So I would answer, bcache tools can run on all architectures, but they are only available (behave correctly) on x86_64 at this moment.
