This series is the result of the work done to add support for the bxCAN
controller to the Linux kernel ([1], [2]). Since these are MMU-less
systems, I had to apply some patches to the userspace tools required to
test the driver. I also submitted a patch to busybox ([3]), but it has
not been accepted yet, and I don't know if it will be in the future. In
the meantime, the rtnl-link-can application can be used.

This series allows the use of CAN devices on MMU-less systems before it
is possible to bump can-utils and libmnl to the new versions containing
these patches.

All 4 patches applied to master, thanks.

I just tweaked the Upstream: tag for the libmnl patch, to point to the
actual URL instead of just the sha1:
    https://git.netfilter.org/libmnl/commit/?id=80442c4e32cde0b27b471c5c9688ee8488f14bec
